Design, synthesis and antiproliferative activity of hydroxyacetamide derivatives against HeLa cervical carcinoma cell and breast cancer cell line
Abstract
Purpose: To design and develop a new series of histone deacetylase inhibitors (FP1 - FP12) and evaluate their inhibitory activity against hydroxyacetamide (HDAC) enzyme mixture-derived HeLa cervical carcinoma cell and MCF-7.
Methods: The designed molecules (FP1 - FP12) were docked using AUTODOCK 1.4.6. FP3 and FP8 showed higher interaction comparable to the prototypical HDACI. The designed series of 2-[[(3- Phenyl/substituted Phenyl-[4-{(4- (substituted phenyl)ethylidine-2-Phenyl-1,3-Imidazol-5-One}](-4H- 1,2,4-triazol-5-yl)sulfanyl]-N-hydroxyacetamide derivatives (FP1-FP12) was synthesized by merging 2- [(4-amino-3-phenyl-4H- 1, 2, 4-triazol-5-yl) sulfanyl]- N-hydroxyacetamide and 2-{[4-amino-3-(2- hydroxyphenyl)-4H-1,2, 4-triazol-5-yl]sulfanyl}-N hydroxyacetamide derivatives with aromatic substituted
oxazolone. The biological activity of the synthesized molecule (FP1-FP12) was evaluated against HDAC enzyme mixture-derived HeLa cervical carcinoma cell and breast cancer cell line (MCF-7).
Results: HDAC inhibitory activity of FP10 showed higher IC50 (half-maximal concentration inhibitory activity) of 0.09 μM, whereas standard SAHA molecule showed IC50 of 0.057 μM. On the other hand, FP9 exhibited higher GI50 (50 % of maximal concentration that inhibited cell proliferation) of 22.8 μM against MCF-7 cell line, compared with the standard, adriamycin, with GI50 of (-) 50.2 μM.
Conclusion: Synthesis, spectral characterization, and evaluation of HDAC inhibition activity and in vitro anticancer evaluation of novel hydroxyacetamide derivatives against MCF-7 cell line have been achieved. The findings indicate the emergence of potentialanticancer compounds.
