(79) outlined the synthesis and evaluation of a series of succinimide hydroxamic acids, which were prepared and evaluated for HDAC inhibition and antiproliferation.
Based on their chemical structures, HDAC inhibitors include short-chain fatty acids, hydroxamic acids, synthetic benzamides, and cyclic peptides, which exhibit various bioactivities and specificities.

Allelopathic agents reported from higher plants include coumarins, flavonoids, alkaloids, tannins, certain quinones, hydroxamic acids, sesquiterpene lactones, and various mono-, sesqui-, di-, and triterpenes, among other compounds, synthesized from either the acetate or the shikimate pathways [3].

A number of synthetic compounds including imidazoles, hydroxamic acids, and phosphazenes are effective urease inhibitors, but limited studies have been conducted on natural products (Ahmad et al.

WP1 shows the use of hydroxamic acids 2 as starting compounds whose oxidation is performed either with the more soluble tetraalkylammonium periodate salts or PhI[(OAc).sub.2] (path a) [17].
Pharmacophore model on histone deacetylase (HDAC) with known hydroxamic acids and cyclic peptides shows four pharmacophore features: one hydrogen acceptor and one hydrophobic and two aromatic rings [17] and in the study with known hydroxamic acids, benzamides, and biphenyl derivatives on HDAC [40] three pharmacophore features were shown: hydrogen acceptors, hydrogen donors, and hydrophobic aromatic ring.
Important secondary metabolites identified as allelochemicals are phenolics, alkaloids, flavonoids, terpenoids, momilactone, hydroxamic acids, brassinosteroids, jasmonates, salicylates, glucosinolates, carbohydrates and amino acids (Kruse et al., 2000; Jabran and Farooq, 2012).
