Derivados de Aminoácidos

D-Histidinol dihydrochloride is a non-nucleoside inhibitor of phosphodiesterase enzymes. It has shown to be an effective inhibitor of topoisomerase II and topoisomerase IV, which are essential for DNA replication, repair and recombination. D-Histidinol dihydrochloride has been shown to inhibit the phosphodiesterase activity of several different types of cellular enzymes, including PDE1A4, PDE2A4 and PDE3A4. This drug also has shown to have some structural similarities with the nucleoside diphosphate analogs cAMP and cGMP. D-Histidinol dihydrochloride may be useful in the treatment of diseases that involve damage to DNA or cells.

N-Chloroacetyl-L-tyrosine is a synthetic, proteolytic enzyme that hydrolyzes proteins containing the amino acid L-tyrosine. It has been shown to inhibit the growth of bacteria by inhibiting the activity of enzymes involved with protein synthesis and peptide bond formation. N-Chloroacetyl-L-tyrosine inhibits the activity of diazonium salt and conjugates, which are involved in polypeptide synthesis and DNA replication. It also has an inhibitory effect on functional groups, such as hydroxyl, amine, sulfhydryl, carboxylate, phosphate, and phosphoric acid.

Beta-alanine tert-butyl ester hydrochloride is a hydrogenated beta-amino acid ester that is used as a peptidomimetic. It has been shown to be absorbed by the intestine and it can be used to focus on chloride channels in the intestinal cells. Beta-alanine tert-butyl ester hydrochloride is an organic solvent and can also be used as an excipient for drug formulations. The molecule has a benzyl group and a chloride group, which are both substituted with hydrogen atoms.

Selenocystine is a non-protein amino acid that belongs to the group of selenoamino acids. Selenocystine is found in plants and microorganisms, where it plays a role in bacterial metabolism. Selenocystine can be synthesized by bacteria from D-glutamate, cysteine, and hydrogen sulfide. It has been shown to have synergistic effects with other compounds such as carbon sources, hydroxyl ions, and subunits. Selenocystine has been shown to inhibit the growth of certain strains of bacteria that are resistant to antibiotics such as penicillin or erythromycin. These effects are mediated through the mitochondrial membrane potential and may also be due to its ability to inhibit microbial respiration.

N2-Lauroyl-L-glutamine is a surfactant that is used in skin care products. It is an amphiphilic molecule that has a hydrophilic head and lipophilic tail, which allows it to form micelles. This surfactant can be found as either the L or D isomer, which are mirror images of each other. The L form is more soluble and less hygroscopic than the D form. N2-Lauroyl-L-glutamine also contains fatty acids, polycarboxylic acid, and monomers. In addition to being used in skin care products, this surfactant can be found in cosmetics such as sunscreens and moisturizers. It also has a polymerization initiator function for silicone polymers and polyurethanes.
