  • Aceclofenac benzyl ester

    CAS:

    Aceclofenac is a nonsteroidal anti-inflammatory drug (NSAID) that belongs to the propionic acid derivative group. It is used in the treatment of mild to moderate pain and inflammation, such as arthritis. Aceclofenac is rapidly hydrolyzed by esterases in the small intestine, resulting in the release of aceclofenac acid. Aceclofenac benzyl ester is a chemical intermediate that has been shown to be an efficient method for producing aceclofenac acid. It can be obtained by reacting bromoacetic anhydride with methyl alcohol and then hydrolyzing the product with strong acids. This compound may contain impurities, such as nucleophilic impurities, which can lead to side effects.

  • Pteroic acid, min95%

    CAS:

    Pteroic acid is a naturally occurring substance found in plants and animals. It has inhibitory activities against enzymes such as butyrate kinase, acetyl-CoA synthetase, and glutamate dehydrogenase. Pteroic acid is used to synthesize quinoxalines, which are used for the treatment of cancer. Pteroic acid also inhibits cell growth by inhibiting protein synthesis. This is done by conjugating with amino acids and inhibiting their uptake into the ribosome. The inhibition of glutamate dehydrogenase may be due to its ability to reduce levels of glutathione, which is an inhibitor of this enzyme.

  • 22,23-Dihydroavermectin B1b (Ivermectin B1b)

    CAS:

    Ivermectin is a drug that belongs to the anthelmintic class of drugs. It is active against roundworms, pinworms, and hookworms. Ivermectin has been shown to have an effect on autoimmune diseases such as multiple sclerosis, systemic lupus erythematosus, and rheumatoid arthritis by inhibiting the inflammatory response. The drug has been shown to inhibit matrix metalloproteinases in vitro and in vivo. The matrix effect is seen when the drug binds to proteins in the blood plasma or tissue matrix, where it inhibits their activity. This inhibition prevents the degradation of collagen, which can lead to tissue damage or renal failure. Ivermectin also binds to striatal dopamine receptors and inhibits dry weight gain in animals infected with Ostertagia ostertagi. Ivermectin is given orally in a single dose of 200 micrograms/kg body weight for treatment of intestinal worms (roundworm,

  • Pantoprazole sulfone N-oxide

    CAS:

    Pantoprazole sulfone N-oxide is a prodrug that is converted to the active form pantoprazole in the stomach where it inhibits gastric acid secretion. Pantoprazole sulfone N-oxide has been shown to be genotoxic, and can cause polyvinyl chloride to degrade when stored together. Reconstituted solution of this drug should be used within 24 hours after reconstitution, as the chemical stability of this drug decreases rapidly. Validation studies have been conducted on different analytical methods for determining pantoprazole concentrations in reconstituted solutions, and these methods have been harmonized with those published by the United States Pharmacopeia (USP). The pump inhibitor activity of pantoprazole sulfone N-oxide has been demonstrated in dogs, and it is also useful for treating acid reflux disease in humans. Pantoprazole sulfone N-oxide is unstable at high temperatures (>25°C), so should not be refrigerated or
