Synthesis, antiproliferation, and docking studies of N-phenyl-lipoamide and 8-mercapto-N-phenyloctanamide derivatives: effects of C6 position thiol moiety
摘要:
Some N-phenyl lipoamide and 8-mercapto-N-phenyloctanamide derivatives were synthesized and their in vitro antiproliferative activity was evaluated. The experimental results indicated that 8-mercapto-N-phenyloctanamides might be good histone deacetylase inhibitors rather than N-phenyl lipoamides, who had thiol moiety at C6 position. To verify the antiproliferation data on structural basis, in silico docking studies of the representative compounds into the crystal structure of histone deacetylase-like protein using AutoDock 4.0 program were performed. Furthermore, sulfur acetylated 8-mercapto-N-phenyloctanamide improved its in vitro antiproliferative activity, probably due to the increasing of its cell membrane permeability. While the identification of enzymatic target of N-phenyl lipoamides with dithiolane is still ongoing.

α-Lipoicacidderivatives were synthesized and evaluated for their in vitro anticancer activities against NCI-460, HO-8910, KB, BEL-7402, and PC-3 cell lines. The results, for most compounds exhibited dose-dependent inhibitory property and several compounds had good inhibitions at the dose of 100 μg/mL. Compound 17m was further selected for in vivo evaluation against S180 xenograft in ICR mice, which

Moreover, the present invention provides a method of treating a patient having a tumor characterized by proliferation of neoplastic cells. Lastly, the present invention provides a pharmaceutical composition comprising a pharmaceutically acceptable carrier and a therapeutically acceptable amount of the compound above.
In order to find novel nonhydroxamate histone deacetylase (HDAC) inhibitors, a series of thiol-based compounds modeled after suberoylanilide hydroxamic acid (SAHA) was synthesized, and their inhibitory effect on HDACs was evaluated. Compound 6, in which the hydroxamic acid of SAHA was replaced by a thiol, was found to be as potent as SAHA, and optimization of this series led to the identification of HDAC inhibitors more potent than SAHA.
