Hydroxamic acid is a potent moiety not only in the field of cancer therapy but also as a mutagenic agent. Among the various derivatives of hydroxamic acid, SAHA (Suberoylanilide Hydroxamic Acid) is considered as a potent anticancer agent. Scientists from the different corner synthesized different hydroxamic acid moieties with some straight chain oxazole, thiadiazole, biphenyl moieties in the terminal position. Acetylation and deacetylation of histones of the core proteins of nucleosomes in chromatin play an important role in the regulation of gene expression. The level of acetylation of histones is established and maintained by two classes of enzymes, histone acetyltransferase and histone deacetylases, which have been identified as transcriptional coactivators and transcriptional corepressors, respectively. There is increasing evidence that aberrant histone acetylation has been linked to various malignant diseases. Great efforts are currently underway for the design of more potent and less toxic candidates for the treatment of cancer. In recent years, hydroxamic acid derivatives have attracted increasing attention for their potential as highly efficacious in combating various etiological factors associated with cancer. Our main intention to draw an attention is that this single functional moiety has not only fit in the receptor but also create a diversified activity.

   Introduction Top

For the last four decades, a number of potential approaches have been proposed for the treatment of cancer. Several targets have already been identified in the process of novel anticancer therapy. One of the recent targets in which nowadays the scientists are showing their maximum interest is Histone Deacetylase (HDAC) enzyme. Great efforts are currently underway for the design of more potent and less toxic candidates for the treatment of cancer. In recent years, hydroxamic acid derivatives have attracted increasing attention for their potential as highly efficacious in combating various etiological factors associated with cancer. Several attempts have already been made prior to synthesizing novel compounds irrespective of the targets; they are molecular modeling, molecular docking, QSAR studies, etc. Among them, molecular docking study was found to be a promising tool as compared with High Throughput Screening (HTS) in overcoming the limitations of unprecedented number of novel leads.

   Histone Deacetylase Structural Features Top

HDAC enzyme was found to be one of the leading targets in the process of anticancer drug development. HDAC have been divided into three distinct structural classes as class (i/ii) zinc dependent and class (iii) as NAD (Nicotinamide adenine dinucleotide) dependent. These enzymes are a part of multiprotein complexes, catalyzing the removal of acetyl group from lysine residue on protein, including histones. HDAC inhibitors have shown to bind the active site and block the substrate access, causing a resultant accumulation of acetylated histones. HDACIs (Histone deacetylase inhibitors) induce tumor growth inhibition, cell differentiation, and programmed cell death. HDACIs induce cancer cell cycle arrest, growth inhibition, differentiation, and programmed cell death. HDACI-induced cell cycle arrest and growth inhibition is usually correlated with transcriptional activation of p21WAF1/CIP1 (cyclin-dependent kinase inhibitor 1 or CDK-interacting protein), p27KIP1 (a cell-cycle regulatory protein that Interacts with cyclin-CDK2 and -CDK4, inhibiting cell cycle progression at G1), GADD45 (Growth Arrest and DNA Damage), inhibition of cyclin A, cyclin D, and thymidylate synthetase. [1]

   Hydroxamic Acid as Anticancer Top

Ragno et al. synthesized a new class of synthetic HDACIs, 3-(4-Aroyl-1-methyl- 1H-pyrrol-2-yl)-N-hydroxy-2-propenamides [2] which show minimal inhibitory concentration against HDAC in restricting the over expression of HDAC.

Kim et al. developed a new class of HDACIs, 3-(4-Substituted-phenyl)-N-hydroxy-2-propenamides by incorporating 1, 4-phenylene carboxamide as linker shows greater HDAC inhibition. [3]

Angibaud et al. developed a series of pyrimidyl-5-hydroxamic acids which was prepared for evaluation as inhibitors of HDAC. Amino-2-pyrimidinyl can be used as a linker to provide HDAC inhibitors of good enzymatic potency. [17]

Codd et al. discovered SAHA (vorinostat, Zolinza®) and trichostatin A are inhibitors of the Zn(II)-dependent class I and class II HDACs resulting inhibition of Zn(II)-dependent HDACs that relaxes the chromatin structure and upregulates transcription. [18]

Gu et al. developed a new series of carbonyl and sulfur-containing analogs of SAHA as a potent inhibition of HDACIs. [19]

Rajak et al. developed two novel series of 2-[5-(4-substitutedphenyl)- [1, 3, 4]-oxadiazol/thiadiazol-2-ylamino]-pyrimidine-5-carboxylic acid [20] (tetrahydro-pyran-2-yloxy)-amides which were designed and synthesized as novel hydroxamic acid-based HDACIs.

   Hydroxamic Acid as Mutagenic and MMP (Matrix Metalloproteinase) Inhibitor Top

Wang et al. evaluated the mutagenicity and antibacterial activity of a series of hydroxamic acids over a huge diversified range of bacterial strains. Among them, Salicylhydroxamic acid has shown antitubercular activity both in vivo and in vitro. [25]

An in vitro antimicrobial evaluation was carried out by Davis et al. for cyclic hydroxamic acid and related lactams which showed the maximal antibacterial effects against E. aerogenes 13048, S. marcescens 13880, K. pneumoniae 10031, P. aeruginosa 10145, E. coli 9723, etc. [26]

Brien et al. developed a complex with iron(III), copper(II), nickel(II), and zinc(II) complexes of salicylhydroxamic acid, anthranilic hydroxamic acid, and benzohydroxamic acid which showed some hydroxamate-peroxidase inhibitor interactions. [27]

Kokare et al. successfully used a novel reagent, phosphoric acid diethyl ester 2-phenyl-benzimidazol-1-yl ester, [28] that was designed and synthesized and its applicability was demonstrated for the preparation of O-alkyl hydroxamic acids. The O-alkyl hydroxamic acids of N-protected amino acids were also synthesized.

Reiter et al. used a series of sterically hindered sulfonamide hydroxamic acids which are the potent inhibitors of MMP-13. The metabolically more stable compounds in the series contain either a monocyclic or bicyclic pyran ring adjacent to the hydroxamate group. [29]

Tommasi et al. discovered a series of hydroxamic acid inhibitors of MMP-13 that do not significantly inhibit MMP-2 (gelatinase-1). MMP-2 has been implicated in the musculoskeletal side effects resulting from pan-MMP inhibition due to findings from spontaneously occurring human MMP-2 deletions. [30]

Sulfonamide hydroxamic acid molecule has a great influence against metalloproteinase enzyme and if that molecule was further substituted with naphthyl molecule, it also shows a greater affinity to that enzyme [Table 2].

   Conclusion Top

So, hydroxamic acid molecule has a greater impact in the field of pharmaceutical chemistry, though it has not only used as an anticancer but also for other mutagenic problems. From the total review, we can conclude that there was a diversified activity profile that occurred due to the changes in the various position of a molecule with the same hydroxamic acid group on the terminal. So, this single molecule can work further more and more with various other compatible groups and not only in the field of cancer therapy but also other associated diseases.
