Design, synthesis, and biological evaluation of novel 2,4-thiazolidinedione derivatives as histone deacetylase inhibitors targeting liver cancer cell line
摘要:
As a part of an ongoing effort to find alternate chemotherapeutic agents for hepatocellular carcinoma, we herein, report the design and synthesis of two novel compounds targeting histone deacetylase (HDAC) with 2,4-thiazolidinedione as zinc chelating group. Further, we demonstrate that these compounds show cytotoxicity that parallels their ability to inhibit HDACs activity in human liver cancer cell line HepG2. The findings obtained in this study indicate that 2,4-thiazolidinedione group may be utilized successfully to inhibit HDAC activity with future potential for lead optimization by chemical derivatization of active compound, N-(6-(2,4-dioxothiazolidin-3- yl)hexyl) benzenesulfonamide.

We report the synthesis of new compounds 4 35 based on structural modifications of different moieties of previously described lead UCM-2550. The new nonpiperazine derivatives, representing second-generation agonists, were assessed for binding affinity, selectivity, and functional activity at the 5-HT1A receptor (5-HT1AR). Computational beta(2)-based homology models of the ligand receptor complexes were used to explain the observed structure affinity relationships. Selected candidates were also evaluated for their potential in vitro and in vivo neuroprotective properties. Interestingly, compound 26 (2-6-[(3,4:-dihydro-2H-chromen-2-ylmethyl)amino]hexyl}-tetrahydro-1H-pyrrolo[1,2-c]imidazole-1,3(2H)-dione) has been characterized as a high-affinity and potent 5-HT1AR agonist (K-i, = 5.9 nM, EC50 = 21.8 nM) and exhibits neuroprotective effect in neurotoxicity assays in primary cell cultures from rat hippocampus and in the MCAO model of focal cerebral ischemia in rats.
