Theoretical 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...
متن کاملSynthesis, Physiochemical Studies And Antimicrobial Screening Of Metal Complexes Of Fe(III) & Au(III) With Amino Acids
Mixed ligand complexes of Iron(III) and Au(III) with succinimide or 8-hydroxyquinoline as primary ligands and amino acids as secondary ligands have been synthesized. The general formula of these complexes are follows: K[Fe(L)2(L′)2] & [Au(Q)( L′)] where L= C4H4O2N(1-5), Q= C9H6NO (6-10); L′=C6H12NO2 (1,9), C6H10N2O4S2(2,6), C3H6O2NS(3), C3H6NO3 (4,7), C9H10O2N (5,8). The complexes were prepared...
متن کاملChromium(V) complexes of hydroxamic acids: formation, structures, and reactivities.
A new family of relatively stable Cr(V) complexes, [Cr(V)O(L)(2)](-) (LH(2) = RC(O)NHOH, R = Me, Ph, 2-HO-Ph, or HONHC(O)(CH(2))(6)), has been obtained by the reactions of hydroxamic acids with Cr(VI) in polar aprotic solvents. Similar reactions in aqueous solutions led to the formation of transient Cr(V) species. All complexes have been characterized by electron paramagnetic resonance spectros...
متن کاملNew complexes of peroxidases with hydroxamic acids, hydrazides, and amides.
Horseradish peroxidase forms spectroscopically distinct, reversible complexes with hydroxamic acids (R-CONHOH), hydrazides (RCO-NHNH2), amides (RCONH2), and oc-hydroxyketones (RCO--CHsOH). Binding of these compounds to the enzyme depends on the polar and steric character of R and the hydrogen bonding capacity of-COX-Y (X-Y = NH-OH, NH-NH,, NH-H, CH,OH). Hydroxamate anions and hydrazide cations ...
متن کاملSynthesis and characterization of fatty hydroxamic acids from triacylglycerides.
In this study, fatty haydroxamic acids (FHAs), which have biological activities as antibiotics and antifungal, have been synthesized via refluxing of triacylglycrides, palm olein, palm stearin or corn oil with hydroxylamine hydrochloride. The products were characterized using the complex formation test of hydroxamic acid group with zinc(I), copper(II) and iron(III), various technique methods in...
