Tenellones A and B from a Diaporthe sp.: two highly substituted benzophenone inhibitors of parasite cGMP-dependent protein kinase activity.

Journal Article (Journal Article)

Parasite cGMP-dependent protein kinase (PKG) has been recently validated as a biochemical target for the treatment of coccidiosis. To discover new anticoccidial leads, we have screened our library of natural product extracts for inhibitors of parasite PKG. Bioassay-guided fractionation of the microbial extracts has led to the discovery of tenellones A (2) and B (3), two new highly substituted benzophenones. The isolation, structure, and activity of these compounds are described.
