Methods for Hydroxamic Acid Synthesis [PDF]
Current Organic Chemistry, 2019 Substituted hydroxamic acid is one of the most extensively studied pharmacophores because of their ability to chelate biologically important metal ions to modulate various enzymes, such as HDACs, urease, metallopeptidase, and carbonic anhydrase. Syntheses and biological studies of various classes of hydroxamic acid derivatives have been reported in ...

Journal of Pharmacy and Pharmacology, 1964 Abstract The preparation of certain quinolines, quinazolines, quinoxalines, benzoxazines and benzothiazines containing the cyclic hydroxamic grouping is described. In vitro antibacterial activities showed that no compound had a broader spectrum of activity than the known 1,2-dihydro-1-hydroxy-2-oxoquinoline.

Antifungal properties of phenyl fatty hydroxamic acids and their copper complexes synthesized based on canola and palm kernel oils [PDF]
, 2013 Phenyl fatty hydroxamic acids (PFHAs) were synthesized by phenyl hydroxylaminolysis of canola or palm kernel oils using lipozyme TL IM as catalyst. Copper complexes of phenyl fatty hydroxamic acids (copper phenyl fatty hydroxamate (Cu-PFHs)) acids were ...

Interaction of solid organic acids with carbon nanotube field effect transistors [PDF]
, 2006 A series of solid organic acids were used to p-dope carbon nanotubes. The extent of doping is shown to be dependent on the pKa value of the acids. Highly fluorinated carboxylic acids and sulfonic acids are very effective in shifting the threshold voltage

Chemical Ligation of Backbone N‐hydroxylated Peptides
Chemistry – A European Journal, EarlyView.Peptide backbone N‐hydroxylation enables sequence‐agnostic fragment ligation via hydroxamate O‐acyl capture and O→N acyl transfer in water. Broad tolerance of sterically demanding nucleophilic residues is observed, and reductive N─O cleavage restores the native amide bond.

International Journal for Parasitology: Drugs and Drug Resistance, 2017 Histone deacetylase inhibitors (HDACi) are being investigated for the control of various human parasites. Here we investigate their potential as insecticides for the control of a major ecto-parasite of sheep, the Australian sheep blowfly, Lucilia cuprina.
