HDAC as onco target: Reviewing the synthetic approaches with SAR study of their inhibitors

Even though one is moving towards the success in the discovery of efficient anti-cancer molecules, the drugs used in the treatment of various malignancies are found to possess toxicity and adverse reactivity in the human body that limit their use. The scientists all over the world are engaged in bringing up strategies that aim to develop small molecules that target the abnormal epigenetic factors. The discovery of the role of Histone deacetylases (HDACs) has promised to be a turning point in the treatment of various malignancies. Thus, the invention of potent and safe anticancer therapeutics agents with minimal adverse and side effects are still a major topic of concern and a huge number of research works have been reported in the past few years. This review has been written to discuss on the influence of Histone Deacetylases in cancer malignancies. We have tried to embrace majority of the developments made till date in the field of HDAC and its inhibitors herein. The drugs that are clinically applied, synthesis and SAR study that highlight the chemical groups responsible for evoking the HDAC inhibition and potential of various new classes of HDAC inhibitors (synthetic, hybrid and natural) have also been included.

Reactions of 5-Mercapto-3-(4′-pyridyl)-s-triazole with alpha-Halogenoketones, 1,2-Dibromoethane and 2,3-Dichloroquinoxaline: Synthesis of Thiazolo<2,3-c>-s-triazoles and s-Triazolo<3',4':2,3>thiazolo<4,5-b>quinoxaline

5-Mercapto-3-(4′-pyridyl)-s-triazole (I; R = 4-pyridyl) reacts with alpha-halogenoketones to give 5-aroylmethylthio-3-(4′-pyridyl)-s-triazoles (IIa-f) which on treatment with PPA undergo cyclodehydration to furnish 5-aryl-3-(4′-pyridyl)thiazolo<2,3-c>-s-triazoles (IIIa-f) and not the isomeric 5-aryl-2-(4′-pyridyl)thiazolo<3,2-b>-s-triazoles (VIIIa-f).The structural assignments of III are based on elemental analyses, spectral data and the unequivocal synthesis of IIIa (R = 4-pyridyl; R1 = p-ClC6H4) by POCl3 cyclization of 4-(p-chlorophenyl)-2-isonicotinylhydrazinothiazole (V) obtained from isonicotinyl thiosemicarbazide (IV) and p-chlorophenacyl bromide.A similar condensation of I (R = 4-pyridyl) with 1,2-dibromoethane yields 5,6-dihydro-3-(4′-pyridyl)thiazolo<2,3-c>-s-triazole (VI) and not its isomer, 5,6-dihydro-2-(4′-pyridyl)thiazolo<3,2-b>-s-triazole (IX).This has also been proved by the unequivocal synthesis of VI by the reaction of IV with 1,2-dibromoethane.The reaction of I (R = 4-pyridyl) with 2,3-dichloroquinoxaline gives 3-(4′-pyridyl)-s-triazolo<3',4':2,3>thiazolo<4,5-b>quinoxaline (VII).

Transition-Metal-Free Cross-Coupling Reactions in Dynamic Thin Films To Access Pyrimidine and Quinoxaline Analogues

The vortex fluidic device (VFD) is effective in modulating the synthesis of pyrimidine and quinoxaline-based compounds at room temperature and in high yield. The formation of the C?N bond occurs in the absence of a transition-metal catalyst, which avoids the contamination of the products with trace amounts of a transition metal. The systematic investigation of the operating parameters for the microfluidic platform in the confined operation mode established an optimum tilt angle of 45 for a 10 mm diameter borosilicate glass tube rotating at 5000 rpm.

Heteroaromatic motifs in resorcinarene-derived cavitand receptors: Structural and functional elements

Cavitands are synthetic receptors typically based on resorcin[4]arenes, macrocyclic concave compounds that are readily available and can be easily transformed into deeper synthetic cavities by attachment of aromatic spacers or panels. The use of aromatic heterocycles is ubiquitous in these structures, either for synthetic convenience, to regulate the dynamic and self-assembling properties of these receptors, or to provide suitable coordination environments for metal-functionalized receptors.

Design, synthesis, and biological evaluation of analogues of the antitumor agent, 2-{4-[(7-chloro-2-quinoxalinyl)oxy]phenoxy}propionic acid (XK469)

2-{4-[(7-Chloro-2-quinoxalinyl)oxy]phenoxy}propionic acid (XK469) is among the most highly and broadly active antitumor agents to have been evaluated in our laboratories and is currently scheduled to enter clinical trials in 2001. The mechanism or mechanisms of action of XK469 remain to be elaborated. Accordingly, an effort was initiated to establish a pharmacophore hypothesis to delineate the requirements of the active site, via a comprehensive program of synthesis of analogues of XK469 and evaluation of the effects of structural modification(s) on solid tumor activity. The strategy formulated chose to dissect the two-dimensional parent structure into three regions – I, ring A of quinoxaline; II, the hydroquinone connector linkage; and III, the lactic acid moiety – to determine the resultant in vitro and in vivo effects of chemical alterations in each region. Neither the A-ring unsubstituted nor the B-ring 3-chloro-regioisomer of XK469 showed antitumor activity. The modulating antitumor effect(s) of substituents of differing electronegativities, located at the several sites comprising the A-ring of region I, were next ascertained. Thus, a halogen substituent, located at the 7-position of a 2-{4-[(2-quinoxalinyl)oxy]phenoxy}propionic acid, generated the most highly and broadly active antitumor agents. A methyl, methoxy, or an azido substituent at this site generated a much less active structure, whereas 5-, 6-, 8-chloro-, 6-, 7-nitro, and 7-amino derivatives all proved to be essentially inactive. When the connector linkage (region II) of 1 was changed from that of a hydroquinone to either a resorcinol or a catechol derivative, all antitumor activity was lost. Of the carboxylic acid derivatives of XK469 (region III), i.e., CONH2, CONHCH3, CON(CH3)2, CONHOH, CONHNH2, CN, or CN4H (tetrazole), only the monomethyl- and N,N-dimethylamides proved to be active.

Synthesis and spectral studies of sterically hindered half-sandwich d6 metal complexes containing quinoxaline based electron rich heterocyclic pyrazoles

Reactions of halide bridged arene d6 metal precursors with the quinoxaline based electron rich heterocyclic (furan or thiophene) pyrazoles (L1-L4) yielded a series of mononuclear complexes 1?16. In general complexes have been formulated as [(arene)MClL]PF6 where L = L1, M = Ru, arene = benzene (1); p-cymene (2); arene = Cp?, M = Rh (3) and Ir (4); L = L2, M = Ru, arene = benzene (5); p-cymene (6); arene = Cp?, M = Rh (7) and Ir (8); L = L3, M = Ru, arene = benzene (9); p-cymene (10); arene = Cp?, M = Rh (11) and Ir (12); L = L4, M = Ru, arene = benzene (13); p-cymene (14); arene = Cp?, M = Rh (15) and Ir (16). All these cationic complexes have been characterized by various spectroscopic techniques. Most of the complexes (except 3, 11, 15 and 16) have been established by single crystal analysis. Structural studies revealed that complexes are mononuclear and X-ray studies suggest that the vicinity around the metal atom is distorted octahedral. Variation in the heterocyclic moiety of the ligands doesn’t influence in the mode of bonding towards the metal atoms in the complexes. Moreover, the molar ratio between the metal precursors and ligands, effect of temperature and the reaction times does not influence the elucidation of the di-nuclear complexes.
