Isolation, structure, and HIV-1 integrase inhibitory activity of Cytosporic acid, a fungal metabolite produced by a Cytospora sp.

Published

Journal Article

HIV-1 integrase is a critical enzyme for replication of HIV, and its inhibition has the potential to lead to an anti-retroviral therapy that has advantages over existing therapies. Cytosporic acid (1) is a polyketide-derived novel natural product that was isolated from a fermentation broth of the filamentous fungus Cytospora sp. collected from Puerto Rico. It inhibited strand transfer reaction of HIV-1 integrase with an IC(50) of 20 microM. The isolation, structure elucidation, relative stereochemistry, and activity of 1 are described.
