Long-chain alkanehydroxamic acids adsorb on the native oxides of metals and formed oriented selfassembled monolayers (SAMs). This study examined SAMs of hydroxamic acids on the native oxides of copper, silver, titanium, aluminum, zirconium, and iron. These SAMs were characterized usingwettability, X-ray photoelectron spectroscopy (XPS), and polarized infrared external reflectance spectroscopy (...

Germination inhibition activity of N-aryl hydroxamic acids and acetanilide analogues was measured on lettuce seeds (Lactuca sativa). Lipophilicity of the compounds was determined by HPLC. A correlation between lipophilicity values and percentage of germination inhibition was established. A model mechanism of action for auxin was used for analyzing the effect of the substituent at the alpha carb...

Fatty hydroxamic acid derivatives were synthesized using Lipozyme TL IM catalyst at biphasic medium as the palm kernel oil was dissolved in hexane and hydroxylamine derivatives were dissolved in water: (1) N-methyl fatty hydroxamic acids (MFHAs); (2) N-isopropyl fatty hydroxamic acids (IPFHAs) and (3) N-benzyl fatty hydroxamic acids (BFHAs) were synthesized by reaction of palm kernel oil and N-...

The development of light-mediated methods for synthetic applications is increasingly attracting high interest. We present herein a new photochemical protocol the synthesis hydroxamic acids, which constitute an important class medicinal agents, mainly due to their anticancer properties. method mediated by UVA-light or sunlight and its key point generation charge transfer complex interaction 4-di...

Hogg, Robert W. (University of Illinois, Urbana), Chitra S. Biswas, and Harry P. Broquist. Interference with valine and isoleucine biosynthesis by cyclic hydroxamic acids. J. Bacteriol. 90:1265-1270. 1965.-The introduction of a hydroxyl group in a number of common barbiturates, a substitution which converts these compounds to cyclic hydroxamic acids, gives rise to compounds which inhibit growth...

Hydroxamic acids, R-CONHOH, are inhibitors specific to the respiratory pathway through the alternate, cyanide-insensitive terminal oxidase of plant mitochondria. The nature of the R group in these compounds affects the concentration at which the hydroxamic acids are effective, but it appears that all hydroxamic acids inhibit if high enough concentrations are used. The benzhydroxamic acids are e...
