Design, synthesis and characterization of podocarpate derivatives as openers of BK channels

Bioorg Med Chem Lett. 2008 Oct 1;18(19):5197-200. doi: 10.1016/j.bmcl.2008.08.081. Epub 2008 Aug 28.

Abstract

We found that the podocarpic acid structure provides a new scaffold for chemical modulators of large-conductance calcium-activated K(+) channels (BK channels). Structure-activity analysis indicates the importance of both the arrangement (i.e., location and orientation) of the carboxylic acid functionality of ring A and the hydrophobic region of ring C for expression of BK channel-opening activity.
