Synthesis and anticancer activity of analogues of phenstatin, with a phenothiazine A-ring, as a new class of microtubule-targeting agents
摘要:
A new family of microtubule-targeting agents with a phenothiazine A-ring was synthesized and evaluated for anti-proliferative activity and interaction with tubulin. These new derivatives showed significant activities against cellular proliferation and tubulin polymerization, rather similar to those of phenstatin. Phenothiazine derivative 21 proved to be the most potent compound synthesized with GI(50) values ranging from 29 to 93 nM on different cell lines. The same compound showed a better inhibition of COLO 205, A498, and MCF7 cell lines than the parent phenstatin. (C) 2012 Elsevier Ltd. All rights reserved.

Two new families of human farnesyltransferase inhibitors 13a-m and 14a-d, based on a phenothiazine scaffold, were synthesized. Compounds 14a and 14b were the most promising inhibitors of human farnesyltransferase with IC50 values of 0.7 and 0.6 mu M, respectively. (C) 2012 Elsevier Masson SAS. All rights reserved.
