Some question about Voriconazole tablets

Voriconazole is a triazole antifungal medication that is generally used to treat serious, invasive fungal infections. These are generally seen in patients who are immunocompromised, and include invasive candidiasis, invasive aspergillosis, and certain emerging fungal infections.

1. What is voriconazole ?

Voriconazole is a medicine used to treat infections caused by yeast or fungi (such as Aspergillus or Candida). It works by killing or interfering with the growth of the yeast or fungi.

You may hear voriconazole called by its brand name Vfend®. Voriconazole comes as a tablet or injection. The tablets contain lactose.

2. How to use voriconazole tablets?

Use voriconazole tablets as directed by your doctor. Check the label on the medicine for exact dosing instructions.

An extra patient leaflet is available with voriconazole tablets. Talk to your pharmacist if you have questions about this information.

Take voriconazole tablets by mouth on an empty stomach at least 1 hour before or 1 hour after eating.

To clear up your infection completely, take voriconazole tablets for the full course of treatment. Keep taking it even if you feel better in a few days.

If you miss a dose of voriconazole tablets, take it as soon as possible. If it is more than 6 hours after the missed dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

3. What should you do if your child misses a dose of voriconazole?

Give the missed dose as soon as you remember.

If it is almost time for the next dose, skip the missed dose. Give the next dose at the regular time.

Do not give your child two doses to make up for one missed dose.

4. What safety measures should you take when your child is using voriconazole?

Your child should avoid grapefruit juice or grapefruit while taking voriconazole. These increase the amount of voriconazole in the blood, which may cause more side effects. Read the labels of mixed fruit juices to ensure that they do not contain grapefruit juice.

Your child may sunburn more easily than normal while taking voriconazole. To help prevent sunburn:

Avoid direct sunlight, especially between 10 a.m. to 3 p.m.

Avoid sunlamps, bright indoor lights, and tanning beds.

Wear a broad-rimmed hat, long sleeves, long pants, or skirt outside.

Apply a sun block with a SPF 15 or higher.

Because voriconazole may cause vision problems, watch your child’s activities closely until you see how voriconazole affects him or her. For example, your child may have problems with schoolwork, riding a bike, or playing sports.

There are some medicines that should not be taken together with voriconazole or in some cases, the dose of voriconazole or the other medicine may need to be adjusted. It is important that you tell your doctor and pharmacist if your child takes any other medications (prescription, over the counter, and herbal) including:

certain medications used to thin the blood (such as warfarin, coumadin)

sirolimus, tacrolimus

cyclosporine

nifedipine, amlodipine

omeprazole

HIV medications

seizure medications (phenytoin, phenobarbital, carbamazepine)

Betamethasone Drugs Information

Betamethasone is a corticosteroid used to treat the inflammation, swelling, and pain of arthritis. Brand name drugs which contain betamethasone include: Celestone, and Celestone Soluspan.

1. Application

Treating certain conditions associated with decreased adrenal gland function. It is used to treat severe inflammation caused by certain conditions, including severe asthma, severe allergies, rheumatoid arthritis, ulcerative colitis, certain blood disorders, lupus, multiple sclerosis, and certain eye and skinconditions. It may be used for certain types of cancer (eg, leukemia). It may also be used for other conditions as determined by your doctor.

Betamethasone is a corticosteroid. It works by modifying the body's immune response to various conditions and decreasing inflammation.

2. Pharmacodynamics

Betamethasone and its derivatives, betamethasone sodium phosphate and betamethasone acetate, are synthetic glucocorticoids. Used for its antiinflammatory or immunosuppressive properties, betamethasone is combined with a mineralocorticoid to manage adrenal insufficiency and is used in the form of betamethasone benzoate, betamethasone dipropionate, or betamethasone valerate for the treatment of inflammation due to corticosteroid-responsive dermatoses. Betamethasone and clotrimazole are used together to treat cutaneous tinea infections.

3. Mechanism of action

Betamethasone is a glucocorticoid receptor agonist. This leads to changes in genetic expression once this complex binds to the GRE. The antiinflammatory actions of corticosteroids are thought to involve lipocortins, phospholipase A2 inhibitory proteins which, through inhibition arachidonic acid, control the biosynthesis of prostaglandins and leukotrienes. The immune system is suppressed by corticosteroids due to a decrease in the function of the lymphatic system, a reduction in immunoglobulin and complement concentrations, the precipitation of lymphocytopenia, and interference with antigen-antibody binding. Betamethasone binds to plasma transcortin, and it becomes active when it is not bound to transcortin.

4. Proper storage of betamethasone

Betamethasone is usually handled and stored by a health care provider. If you are using betamethasone at home, store betamethasone as directed by your pharmacist or health care provider. Keep betamethasone out of the reach of children and away from pets.

5. Toxicity

Symptoms of overdose include burning, itching, irritation, dryness, folliculitis, hypertrichosis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, maceration of the skin, secondary infection, skin atrophy, striae, and miliaria.

6. Indication

Topical use (cream, lotion and ointment): for relief of the inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses

Topical use (foam): relief of the inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses of the scalp

Systemic use: for the treatment of edocrine disorders, rheumatic disorders, collagen diseases, dermatological diseases, allergic states, ophthalmic diseases, respiratory diseases, hematologic disorders, neoplastic diseases, edematous states, gastrointestinal diseases, tuberculous meningitis and trichinosis.

1,2,3-Propanetriol Health Information

1,2,3-Propanetriol is a naturally occurring chemical. 1,2,3-Propanetriol (or glycerine, glycerin) is a simple polyol (sugar alcohol) compound. It is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. 1,2,3-Propanetriol has three hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature. The 1,2,3-Propanetriol backbone is central to all lipids known as triglycerides. 1,2,3-Propanetriol is sweet-tasting and of low toxicity.

6 . Fire Fighting Measures

General Information:As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. Containers may explode when heated.

Media:Use water spray to cool fire-exposed containers. Use agent most appropriate to extinguish fire. Use water spray, dry chemical, carbon dioxide, or appropriate foam.

Calcium carbonate in Industrial

Calcium carbonate, or CaCO3, comprises more than 4% of the earth’s crust and is found throughout the world.  Its most common natural forms are chalk, limestone, and marble, produced by the sedimentation of the shells of small fossilized snails, shellfish, and coral over millions of years.  Although all three forms are identical in chemical terms, they differ in many other respects, including purity, whiteness, thickness and homogeneity.  Calcium carbonate is one of the most useful and versatile materials known to man.

Calcium carbonate, as it is used for industrial purposes, is extracted by mining or quarrying.  Pure calcium carbonate can be produced from marble, or it can be prepared by passing carbon dioxide into a solution of calcium hydroxide.  In the later case calcium carbonate is derived from the mixture, forming a grade of product called "precipitated calcium carbonate,” or PCC. PCC has a very fine and controlled particle size, on the order of 2 microns in diameter, particularly useful in production of paper.  The other primary type of industrial product is "ground calcium carbonate,” or GCC. GCC, as the name implies, involves crushing and processing limestone to create a powdery-like form graded by size and other properties for many different industrial and pharmaceutical applications.


The main use of calcium carbonate is in the construction industry, either as a building material or limestone aggregate for roadbuilding or as an ingredient of cement or as the starting material for the preparation of builder's lime by burning in a kiln. However, due to weathering mainly caused by acid rain, calcium carbonate (in limestone form) is no longer used for building purposes on its own, and only as a raw/primary substance for building materials.


Calcium carbonate(CAS.NO:471-34-1) is also used in the purification of iron from iron ore in a blast furnace. The carbonate is calcined in situ to give calcium oxide, which forms a slag with various impurities present, and separates from the purified iron.

In the oil industry, calcium carbonate is added to drilling fluids as a formation-bridging and filtercake-sealing agent; it is also a weighting material which increases the density of drilling fluids to control the downhole pressure. Calcium carbonate is added to swimming pools, as a pH corrector for maintaining alkalinity and offsetting the acidic properties of the disinfectant agent.

It is also used as a raw material in the refining of sugar from sugar beet; It is calcined in a kiln with anthracite to produce calcium oxide + carbon dioxide. This burnt lime is then slaked in sweet water to produce a calcium hydroxide suspension for the precipitation of impurities in raw juice during carbonatation.

Calcium carbonate has traditionally been a major component of blackboard chalk. However, modern manufactured chalk is mostly gypsum, hydrated calcium sulfate CaSO4·2H2O. Calcium carbonate is a main source for growing Seacrete, or Biorock. Precipitated calcium carbonate (PCC), pre-dispersed in slurry form, is a common filler material for latex gloves with the aim of achieving maximum saving in material and production costs.

Fine ground calcium carbonate (GCC) is an essential ingredient in the microporous film used in babies' diapers and some building films as the pores are nucleated around the calcium carbonate particles during the manufacture of the film by biaxial stretching. GCC or PCC is used as a filler in paper because they are cheaper than wood fiber. In terms of market volume, GCC are the most important types of fillers currently used. Printing and writing paper can contain 10–20% calcium carbonate. In North America, calcium carbonate has begun to replace kaolin in the production of glossy paper. Europe has been practicing this as alkaline papermaking or acid-free papermaking for some decades. PCC has a very fine and controlled particle size, on the order of 2 micrometres in diameter, useful in coatings for paper.


Calcium carbonate is widely used as an extender in paints, in particular matte emulsion paint where typically 30% by weight of the paint is either chalk or marble. It is also a popular filler in plastics.Some typical examples include around 15 to 20% loading of chalk in unplasticized polyvinyl chloride (uPVC) drain pipe, 5 to 15% loading of stearate coated chalk or marble in uPVC window profile. PVC cables can use calcium carbonate at loadings of up to 70 phr (parts per hundred parts of resin) to improve mechanical properties (tensile strength and elongation) and electrical properties (volume resistivity). Polypropylene compounds are often filled with calcium carbonate to increase rigidity, a requirement that becomes important at high use temperatures. Here the percentage is often 20–40%. It also routinely used as a filler in thermosetting resins (sheet and bulk molding compounds) and has also been mixed with ABS, and other ingredients, to form some types of compression molded "clay" poker chips. Precipitated calcium carbonate, made by dropping calcium oxide into water, is used by itself or with additives as a white paint, known as whitewashing.

Calcium carbonate is added to a wide range of trade and do it yourself adhesives, sealants, and decorating fillers. Ceramic tile adhesives typically contain 70 to 80% limestone. Decorating crack fillers contain similar levels of marble or dolomite. It is also mixed with putty in setting stained glass windows, and as a resist to prevent glass from sticking to kiln shelves when firing glazes and paints at high temperature.


In ceramics/glazing applications, calcium carbonate is known as whiting, and is a common ingredient for many glazes in its white powdered form. When a glaze containing this material is fired in a kiln, the whiting acts as a flux material in the glaze. Ground calcium carbonate is an abrasive (both as scouring powder and as an ingredient of household scouring creams), in particular in its calcite form, which has the relatively low hardness level of 3 on the Mohs scale of mineral hardness, and will therefore not scratch glass and most other ceramics, enamel, bronze, iron, and steel, and have a moderate effect on softer metals like aluminium and copper. A paste made from calcium carbonate and deionized water can be used to clean tarnish on silver.

A anti-inflammatory drug :Naproxen

Naproxen is a non-steroidal anti-inflammatory drug. It is also known as an NSAID. It is used to relieve pain and inflammation in rheumatic disease, sprains, strains, backache, gout, and period (menstrual) pain.

1. Medical uses

Naproxen(CAS.NO:22204-53-1) is commonly used for the reduction of pain, fever, inflammation and stiffness caused by conditions including migraine, osteoarthritis, kidney stones, rheumatoid arthritis, psoriatic arthritis, gout, ankylosing spondylitis, menstrual cramps, tendinitis and bursitis. It is also used for the treatment of primary dysmenorrhea.

2. Mechanism of action

Naproxen works by blocking a substance in the body called cyclo-oxygenase (also known as COX) which is involved in the production of certain irritant chemicals in response to injury or disease. By blocking the action of COX, naproxen reduces the symptoms of pain and inflammation.


Some forms of naproxen have a special enteric coating to help protect your stomach against irritation. There is also a modified-release form of tablets which allows naproxen to be released slowly to give a more even pain-relieving effect. Naproxen can be used alone, or alongside medicines such as misoprostol or esomeprazole which help protect against stomach irritation.

3. How to store naproxen

*Keep all medicines out of the reach and sight of children.

*Store in a cool, dry place, away from direct heat and light.

4. Dosing

The usual adult dose for pain is 250 every 6 to 8 hours or 500 mg twice daily using regular naproxen tablets. The usual dose for Naprelan controlled release tablets is 750 to 1000 mg given once daily. For EC-Naprosyn, the usual dose is 375-500 mg twice daily.

Naproxen should be given with food to reduce upset stomach. The dose for rheumatoid arthritis, osteoarthritis, or ankylosing spondylitis is 500 to 1000 mg every 12 hours. Dysmenorrhea is treated with 250 mg every 6 to 8 hours after an initial dose of 500 mg.

5. Warning


Nonsteroidal anti-inflammatory drugs (including naproxen) may rarely increase the risk for a heart attack or stroke. The risk may be greater if you have heart disease or increased risk for heart disease (for example, due to smoking, family history of heart disease, or conditions such as high blood pressure or diabetes), or with longer use. This drug should not be taken right before or after heart bypass surgery (CABG).

Properties of Proline

Proline (abbreviated as Pro or P) is an α-amino acid, one of the twenty DNA-encoded amino acids. Its codons are CCU, CCC, CCA, and CCG. It is not an essential amino acid, which means that the human body can synthesize it. It is unique among the 20 protein-forming amino acids in that the amine nitrogen is bound to not one but two alkyl groups, thus making it a secondary amine. The more common L form has S stereochemistry.

Proline and its derivatives are often used as asymmetric catalysts in organic reactions. The CBS reduction and proline catalysed aldol condensation are prominent examples. L-Proline is an osmoprotectant and therefore is used in many pharmaceutical, biotechnological applications.

D-Proline (CAS NO.344-25-2) is used as synthesizing the drugs. D-Proline , with CAS number of 344-25-2, It is a white to off-white powder.

Cypermethrin used in agricultural

Cypermethrin belongs to a class of insecticides known as synthetic pyrethroids, found in Cynoff EC, Cynoff WP, Cyper TC Termiticide, Cyper WP, and Demon WP pesticide concentrates. Synthetic pyrethroids are man-made insecticides created to mimic the chemical properties of the naturally-occurring insecticide pyrethrum, which comes from the crushed petals of the Chrysanthemum flower. Synthetic pyrethroids, like cypermethrin, are often preferred to the real thing as active ingredients because they offer the added bonus of remaining effective for longer periods of time.

1. Application

Cypermethrin is a synthetic pyrethroid used as an insecticide in large-scale commercial agricultural applications as well as in consumer products for domestic purposes. It behaves as a fast-acting neurotoxin in insects. It is easily degraded on soil and plants but can be effective for weeks when applied to indoor inert surfaces. It was synthesised in 1974 and first marketed in 1977, by Shell.

Cypermethrin is highly toxic to fish, bees and aquatic insects, according to the National Pesticides Telecommunications Network (NPTN). It is found in many household ant and cockroach killers, including Raid and ant chalk. Cypermethrin is a synthetic chemical similar to the pyrethrins in pyrethrum extract (whichcomes fromthe chrysanthemum plant). Pyrethroids, including cypermethrin were designed to be effective longer than pyrethrins.

2. Environmental effects

Cypermethrin is a broad-spectrum insecticide, which means it kills beneficial insects and animals as well as the targeted insects. Fish are particularly susceptible to cypermethrin.Resistance to cypermethrin has developed quickly in insects exposed frequently and can render it ineffective.

The typical half-life of cypermethrin in the soil is 30 days, although it can range from two to eight weeks. Soil microbes rapidly break down cypermethrin. Cypermethrin has an extremely low potential to move in the soil. It is unlikely to contaminate groundwater because it binds tightly to soil particles.

3. Mechanism

Cypermethrin begins working immediately upon contact or ingestion, leading to insect knock-down and death. Cypermethrin kills by acting as a high-power poison to the central nervous system. Once poisoned, the insect’s nerve cells become excited, causing paralysis and preventing normal feeding and grooming activities. Absence of these activities leads to the insect’s eventual or immediate death.

4. Cypermethrin Toxicity

Cypermethrin has low toxicity to humans, mammals and birds.


Excessive exposure can cause nausea, headache, muscle weakness, salivation, shortness of breath and seizures. In humans, cypermethrin is deactivated by enzymatic hydrolysis to several carboxylic acid metabolites, which are eliminated in the urine. Worker exposure to the chemical can be monitored by measurement of the urinary metabolites, while severe overdosage may be confirmed by quantitation of cypermethrin in blood or plasma.

It behaves as a fast-acting neurotoxin in insects. It is easily degraded on soil and plants but can be effective for weeks when applied to indoor inert surfaces. Exposure to sunlight, water and oxygen will accelerate its decomposition. Cypermethrin is highly toxic to fish, bees and aquatic insects, according to the National Pesticides Telecommunications Network (NPTN). It is found in many household ant and cockroach killers, including Raid and ant chalk.

Medicine:Metformin Hydrochloride

Metformin Hydrochloride Tablets 500mg belong to a group of medicines called biguanide oral anti−hyperglycaemic agents. It works by lowering your blood−sugar level.

Metformin Hydrochloride(CAS.NO:1115-70-4) is used to treat non−insulin dependent diabetes when a change of diet has failed to reduce blood sugar levels, particularly if overweight.It may be used alone as initial therapy or along with another group of medicines called sulphonylureas, which stimulate the pancreas to produce more insulin. Sometimes Metformin Hydrochloride is also used to treat patients suffering from insulin dependent diabetes, who are over weight (obese) and whose symptoms are poorly controlled.

If your blood sugar levels are not controlled, it can lead to serious problems such as kidney damage, amputations and blindness. Metformin Hydrochloride is thought to work by decreasing the amount of sugar absorbed from food through the stomach, by helping the body respond better to the insulin it makes naturally and by decreasing the amount of sugar produced by the liver and kidneys.

2. Uses of Metformin hydrochloride

Metformin hydrochloride is an oral hypoglycemic agent. It can lower plasma glucose levels and improves insulin sensitivity. Metformin hydrochloride Inhibits hepatic gluconeogenesis via activation of the LKB1/AMPK pathway. Displays antiproliferative effects in cancer cell lines.

3. Production of Metformin hydrochloride

Metformin hydrochloride is derived by Dimethylamine salt reacting with Dicyandiamide

4. Mechanism of Action


Metformin is an antihyperglycemic agent which improves glucose tolerance in patients with type 2 diabetes, lowering both basal and postprandial plasma glucose. Its pharmacologic mechanisms of action are different from other classes of oral antihyperglycemic agents. Metformin decreases hepatic glucose production, decreases intestinal absorption of glucose, and improves insulin sensitivity by increasing peripheral glucose uptake and utilization. Unlike sulfonylureas, metformin does not produce hypoglycemia in either patients with type 2 diabetes or normal subjects (except in special circumstances, see PRECAUTIONS) and does not cause hyperinsulinemia. With metformin therapy, insulin secretion remains unchanged while fasting insulin levels and day-long plasma insulin response may actually decrease.

Where can you get Di-tert butyl dicarbonate?

Di-tert-butyl dicarbonate is a reagent widely used in organic synthesis. This carbonate ester reacts with amines to give N-tert-butoxycarbonyl or so-called t-BOC derivatives. These derivatives do not behave as amines, which allows certain subsequent transformations to occur that would have otherwise affected the amine functional group. The t-BOC can later be removed from the amine using acids. Thus, t-BOC serves as a protective group, for instance in solid phase peptide synthesis. It is unreactive to most bases and nucleophiles, allowing for an orthogonal Fmoc protection.
Di-tert-butyl-dicarbonate Using:

1、Di-tert-butyl-dicarbonate (DIBOC) is used  in the organic synthesis to introduce amino acid protection gene.
                               
2、Because it must synthesize one kind of compound similar to the natural multi-peptide, also must connect each kind of optical rotation amino acid to certain length the peptide chain according to certain order, when needed to combine  one kind of amino acid the carboxyl group and another kind of amino acid amino, must prevent to combine identical kind of amino acid mutually, therefore, in synthesis , it must protect certain aminos or the carboxyl group,In order to react in the way which is required to carry on.

3、Di-tert-butyl dicarbonate is one well capable protecting agent for amino acid , utilized specially in the amino acid amino protection, widely applied in the medicine, the protein and the multi-peptide synthesis, biochemistry food, the cosmetics and many kinds of product synthesis.In. Compared with the traditional amino acid protecting agent like chloro-carbonic acid animal pen ester, the chloro-carbonic acid - P wu formic acid, it has the following merit:

a、Competitive price


b、No intense irritant flavor, no harm to human body, but may cause skin allergy if contact the skin directly, and may strip with water.


c、Using this product to synthesize the multi-peptides, the remove condition of this protection gene is temperate, and it is easier to separate the responded product compared with using other types of amino acid protecting agent.


d、Has the ignitability, but does not belong to flammable explosive
