Pim kinase inhibitory and antiproliferative activity of a novel series of meridianin C derivatives

Bioorg Med Chem Lett. 2014 Jun 1;24(11):2424-8. doi: 10.1016/j.bmcl.2014.04.035. Epub 2014 Apr 16.

Abstract

A novel series of meridianin C derivatives substituted at C-5 position were prepared. These derivatives were tested for their kinase inhibitory potencies against all three family members of the pim kinases (Pim-1, Pim-2 and Pim-3). In addition, their antiproliferative activity towards three human leukemia cell lines as MV4-11, Jurkat clone E6-1 and K562 has been evaluated. Structure activity relationships at C-3 and C-5 positions of indole were performed to better understand the mechanism behind the enhanced potency. Compound 7f, the most active compound of the series showed a single-digit nanomolar IC50 with selectivity towards Pim-1 kinase.

Keywords: 3,5-Disubstituted indole; Antiproliferative activity; Inhibitor; Meridianin C; Pim kinase.
