4-Nitrophenyl Anthranilate
CAS:Controlled Product4-Nitrophenyl anthranilate is a potent inhibitor of serine protease. It is synthesized by reacting an anthranilate with an hydroxyl group in the presence of ultraviolet light, and can be used as a fluorescent probe. 4-Nitrophenyl anthranilate binds to the active site of serine protease, and prevents the hydrolysis of proteins by blocking the cleavage of peptide bonds at the carboxylic acid termini. This compound has been shown to inhibit human serum albumin and cell nuclei in vitro. The reaction mechanism for this compound is unknown, but it is believed that it may involve a photo-induced electron transfer mechanism.

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.

Discontinued product4-Aminoacetophenone
CAS:4-Aminoacetophenone is an inhibitor of the enzyme acetylcholinesterase and it is used as an insecticide. It inhibits the enzyme by forming hydrogen bonding interactions with the active site. The inhibition of this enzyme leads to paralysis and death in insects. 4-Aminoacetophenone has been shown to have anti-cancer effects in vitro, which may be due to its ability to inhibit glycoside hydrolases and amine oxidases that are involved in cancer development. The compound also has a thermal expansion coefficient that is comparable to other polymers used in drug delivery systems.

Discontinued product4-Acetyl-1,8-naphthalic anhydride
CAS:4-Acetyl-1,8-naphthalic anhydride is a naphthoquinone that has been shown to have apoptosis-inducing properties. It inhibits mitochondrial electron transport and the generation of ATP, leading to cell death. 4-Acetyl-1,8-naphthalic anhydride also binds to DNA, which prevents transcription and replication. This compound can be used in vivo assays to evaluate the efficacy of anticancer drugs by determining tumor growth inhibition or the induction of apoptosis in cancer cells. The binding affinity of 4-acetyl-1,8-naphthalic anhydride for DNA is approximately two orders of magnitude higher than its affinity for other cellular components such as proteins or lipids.

Discontinued product2,6-Dimethylaniline hydrochloride
CAS:Ropivacaine Related Compound A is a chemical compound that has not been fully characterized. It is an inhibitor of the enzyme P-hydroxybenzoic acid, which is involved in the synthesis of tyrosine and phenylalanine. Ropivacaine Related Compound A has shown to be potent inducers of the enzyme polymerase chain reaction (PCR) when combined with other chemicals such as potassium peroxydisulfate. The optimum concentration for this chemical compound to inhibit PCR reactions is 50 mM. Ropivacaine Related Compound A may have carcinogenic potential due to its ability to form p-hydroxybenzoic acid and other carcinogenic compounds. This chemical compound has been found to be a good candidate for wastewater treatment due to its low potency and high solubility in water.

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.
