Discontinued productVitamin A palmitate
CAS:Vitamin A palmitate is a fat-soluble vitamin that has antioxidant properties. It is available as a supplement in the form of retinol and retinyl palmitate. Vitamin A palmitate is an inactive form of vitamin A that can be converted to retinol in vivo by esterases and other enzymes. The conversion of vitamin A palmitate to retinol may be inhibited by various substances, such as estradiol benzoate. This conversion leads to the formation of free radicals, which cause oxidative injury to cells. Studies have shown that vitamin A palmitate can be toxic for humans because it interferes with the synthesis of mucin, an important constituent of human lungs and airways. Vitamin A palmitate also alters gene expression in some experimental models, leading to changes in cell growth or death.

CAS:Pancreastatin is a cytosolic protein that inhibits the production of peptide hormones such as glucagon, insulin, and gastrin. It is used to treat bowel disease, including carcinoid syndrome and inflammatory bowel disease. Pancreastatin has been shown to inhibit the activity of cyclase enzymes that are responsible for the production of these hormones. Pancreatic beta-cells produce pancreatic polypeptide (PP), which is converted by pancreastatin into inactive PP2. Pancreatic alpha-cells produce somatostatin (SS), which is converted by pancreastatin into inactive SS2. Pancreatic delta cells produce pancreatic polypeptide (PP), which is not affected by pancreastatin. Pancreatic somatostatinomas secrete SS, which is not affected by pancreastatin.

Discontinued productMethyl L-tyrosinate
CAS:Methyl-L-tyrosinate is a drug that has been shown to increase the activity of tyrosinase, an enzyme involved in the production of melanin. It also prevents the oxidation of tyrosine and phenylalanine, which are precursors to melanin. Methyl L-tyrosinate has been studied for its potential effects on hepatitis and Parkinson's disease. This drug binds to the hydroxyl group of tyrosinase and inhibits its activity. The inhibition of this enzyme leads to a decrease in melanin synthesis, which may be beneficial for those with vitiligo or other skin disorders where pigment loss is desired. This drug also prevents oxidative carbonylation and functional assays have shown that it has an affinity for potassium ion coordination chemistry.
