Chemistry and Biology of Hydroxamic Acids
The action of salicylhydroxamic acid and its halogen derivatives against tuberculosis, fungi, trypanosomae, and the biosynthesis of cholesterol are described. Their hypoglycemic and phospholipid lowering actions are also mentioned. The author suggested, in 1948, the use of salicylhydroxamic acid I (X = Y = Z = R = H)—called SH—as an antitubercular agent [26]. The suggestion was based on the hyp...
متن کاملQuantum Chemistry Study & Evaluation of Basis Set Effects on Prediction of Amino Acids Properties:
The potential energy surface of gaseous glycine determined years ago in the ab initio B3LYP/6-311++G** calculations is composed of thirteen stable conformers. We performed the ab initiomolecular orbital calculations as the starting point to carry out a force field and normal coordinatecalculation on the most stable conformer of non-zwitterionic glycine [conformer (I)]. Thecalculations were carr...
متن کاملInhibition of urease activity by hydroxamic acid derivatives of amino acids.
Hydroxamic acids have been reported to be potent and specific inhibitors of urease (EC 3.5.1.5) activity of plant and bacterial origin. The present investigation was performed on the inhibitory effect of hydroxamic acid derivatives of naturally occurring amino acids on the urease activity of the Jack Bean and the alimentary tracts of rats. Methionine-hydroxamic acid was the most powerful inhi...
متن کاملTheoretical Studies on Hydroxamic Acids
Hydroxamic acids find many applications in chemistry and biology and have been the subject of many experimental investigations. Theoretical studies are not as frequent. However, the smallest homolog, formohydroxamic acid (FHA), has been studied at various levels, including high-level ab initio and density functional with large basis sets. All studies indicate that it exists as the Z-amide tauto...
