Inhibitors of the oncogenic transcription factor AP-1 from Podocarpus latifolius

J Nat Prod. 2011 Mar 25;74(3):374-7. doi: 10.1021/np100736y. Epub 2011 Feb 9.

Abstract

An activator protein-1 (AP-1) based bioassay-guided phytochemical investigation on Podocarpus latifolius led to the isolation of three new sempervirol-type diterpenes, cycloinumakiol (1), inumakal (2), and inumakoic acid (3), along with three known norditerpenes (4-6). Compounds 4 and 6 were responsible for the observed bioactivity.
