Abstract
During a chemotaxonomic survey of Calophyllum extracts present in the National Cancer Institute's natural product repository, four new pyran ocoumarins were isolated from extracts of C. lanigerum var. austrocori aceum and C. teysmannii var. inophylloide (King.) P. F. Stevens (Clusi aceae). The structure elucidation and anti-HIV activity of calanolide E2 (4), cordatolide E (5), pseudocordatolide C (6), and calanolide F ( 9), along with a simple prenylated coumarin precursor (11), are descri bed here.
