Discovery of 1H-benzo[d][1,2,3]triazol-1-yl 3,4,5-trimethoxybenzoate as a potential antiproliferative agent by inhibiting histone deacetylase
摘要:
Twenty-one benzotriazoles (3-16 and 18-24) were synthesized and half of them (5, 8-16, 20, and 21) were reported for the first time. Their antiproliferative activities against three human cancer cells were assayed. It revealed that 1H-benzo[d][1,2,3] triazol-1-yl 3,4,5-trimethoxybenzoate (9) showed considerable activity against three human cancer cell lines with the half maximal inhibitory concentration (IC50) values of 1.2-2.4 nM, which were close to the value of the positive control, doxorubicin. Further investigation indicated compound 9 was a potential histone deacetylase inhibitor (IC50 = 9.4 mu M) and its binding mode was simulated using docking method. (C) 2010 Elsevier Ltd.

The HIV-1 nucleocapsid (NCp7), structurally defined by zinc-binding domains, participates in crucial stages of the HIV-1 lifecycle and is mutationally nonpermissive, making it an attractive anti-HIV target. Mode of action studies have shown that the secondary structure and activity of NCp7 can be disrupted by acyl transfer from N-2-mercaptobenzoyl-amino amides. We have developed an improved one-pot reaction that affords N-2-mercaptobenzoyl-amino acids on multi-gram scales. This synthetic route allows for rapid modular construction and has greatly expanded the scope of easily accessible potential NCp7 inhibitors. Published by Elsevier Ltd.
