CAS:Meclofenamate sodium hydrate is a non-steroidal anti-inflammatory drug that inhibits cyclooxygenase, lipoxygenase, and phospholipase A 2 . It has been shown to be effective in the treatment of many diseases such as rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, and gout. Meclofenamate sodium hydrate is a potent inducer of polymorphonuclear leucocytes, which are cells involved in the inflammatory response. It also reduces the production of prostaglandins and leukotrienes by inhibiting cyclooxygenase and lipoxygenase enzymes. This agent is very potent in inhibiting diphosphatidylinositol 4-kinase (DPP IV), which is involved in the degradation of glucocorticoids.Formula:C14H12Cl2NNaO3Purity:Min. 95%Molecular weight:336.1 g/molDexamethasone palmitate

CAS:Triphenylmethanol (TPM) is an inhibitor of the enzyme alcohol dehydrogenase. It is synthesized by reacting p-hydroxybenzoic acid with a hydroxyl group in the presence of trifluoroacetic acid and potassium carbonate. The reaction solution was then analyzed by x-ray crystallography, revealing the molecular structure of TPM. TPM binds to the metal ion in a hydroxyl group, preventing alcohol dehydrogenase from oxidizing ethanol to acetaldehyde. This mechanism also explains why TPM inhibits other enzymes that use this same metal ion cofactor such as carboxypeptidase A and aminopeptidase P, which are involved in protein synthesis and degradation. Triphenylmethanol (TPM) is an inhibitor of the enzyme alcohol dehydrogenase. It is synthesized by reacting p-hydroxybenzoic acid with a hydroxyl group in the presence of trifFormula:C19H16OPurity:Min. 95%Color and Shape:White Beige Slightly Yellow PowderMolecular weight:260.33 g/mol2-{N2-[NAlpha-Benzoylbenzoicamido-N6-6-biotinamidocaproyl]lysinylamido}ethyl-2’-(N-sulfosuccinimidyl
