They have found applications as histone deacetylase inhibitors widely applied in cancer treatment such as vorinostat, belinostat, panobinostat and trichostatin A. They are amides where the hydrogen H atom of NH center has been replaced by an OH. Hydroxamates are deprotonated product of hydroxamic acid and acts as excellent ligand.

Introduction Hydroxamates are class of organic compounds bearing the functional group RICON OH RII as organic residues and CO as a carbonyl group.

The C-N C N-C core of carbodiimides N C N is linear, being related to the negatively charged oxygen must first be activated into a better leaving group. Cipemastat, marimastat, periostat, ilomastat and batimastat are all hydroxamate-based inhibitors of matrix metalloproteinase and are by so used in management of cardiovascular diseases. Hydroxamic acids have been the source of much biochemical interest in recent years reflecting the fact that they demonstrate a wide variety of biological activities.

There are hydroxamates with reported anti-HIV activity such as the hydroxyurea which acts as inhibitors of cellular enzyme ribonucleoside diphosphate reductase. 1 Hydroxamates have high affinity for ferric ions that nature has evolved families of hydroxamic acids to function as no N-binding compounds siderophores in bacteria.

Synthesis of Benzohydroxamic Acid 3 The synthesis of compound 3 was achieved by reacting methyl benzoate 1 and hydroxylamine 2. Synthesis of Hydroxamates Using N, N1, NII–trimethoxy-N, NI, NII-trimethyl Phosphorus Triamides 5 Nui et al 31 reported the conversion of aromatic and aliphatic carboxylic acids, including sterically hindered substrates directly to hydroxamates using N, NI, NII-trimethoxy-N, NI, NII–trimethyl phosphorus triamide 5.
