Methyl 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.

Discontinued product5-Deazariboflavin
CAS:5-Deazariboflavin is a proton carrier that is found in the mitochondrial cytochrome b. It has been shown to bind covalently to the protein, forming 5-deazariboflavin-protein adducts. These adducts are formed by reacting with amines and other amino acids present in the protein. In vitro studies have shown that 5-deazariboflavin inhibits Mycobacterium avium growth and acid production by binding to the enzyme pyruvate kinase, which is involved in glycolysis. 5-Deazariboflavin can also be used as an indicator of pH because it is reduced at low pH levels and oxidized at high pH levels. The second order rate constant for this reaction can be determined using kinetic data, such as absorbance or fluorescence properties.

CAS:Controlled Product2-Aminoacetophenone hydrochloride is a chemical compound that is used in analytical chemistry as a reagent for the determination of protein and amino acid concentrations. This reagent can be prepared in various forms, depending on the type of analysis being performed. 2-Aminoacetophenone hydrochloride is used to determine the concentration of free amino acids in a sample by binding to it. It can also be used for determining the concentration of bound amino acids by reacting with them with hydrochloric acid. 2-Aminoacetophenone hydrochloride is an excellent substrate for matrix effect, which may cause errors in measurement due to interference from other substances present in the sample. The use of light exposure reduces this problem by removing interfering substances from the sample.

Discontinued productCyclohexylstatine
CAS:Cyclohexylstatine is a glycopeptide antibiotic that inhibits the synthesis of collagen in animals and humans. It also has been shown to have anticancer activity. Cyclohexylstatine works by inhibiting the biosynthesis of collagen, which is an important component of skin, ligaments, and tendons. The molecule was synthesized in 1975 and has been used as a pharmaceutical agent since 1980. Cyclohexylstatine is the first anti-collagen drug to be developed for use in humans. It has been shown to be effective against autoimmune diseases such as rheumatoid arthritis but not against cancer cells or bacteria. Cyclohexylstatine binds to the zymogen form of collagenase and inhibits its activity. This inhibition leads to an accumulation of polysaccharides in the extracellular matrix that are converted into oligosaccharides by glycosidases present in tissue fluids. These oligosaccharides inhibit collagen synthesis by binding to

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.
