Isolation and Characterization of Aphidicolin Derivatives from Tolypocladium inflatum

Molecules. 2017 Jul 12;22(7):1168. doi: 10.3390/molecules22071168.

Abstract

Inflatin G (1), a new aphidicolin analogue, together with seven known compounds inflatin A (2), inflatin B (3), aphidicolin (4), aphidicolin-17-monoacetate (5), gulypyrone A (6), pyridoxatin rotamers A (7) and B (8), were isolated from the ascomycete fungus Tolypocladium inflatum. Their structures were determined through NMR analyses and the circular dichroism data of the in situ formed [Rh₂(OCOCF₃)₄] complexes. Compounds 1, 4, 5, 7, and 8 showed modest cytotoxicity against four human cancer cell lines A549, CNE1-MP1, A375, and MCF-7.

Keywords: Tolypocladium inflatum; biological activities; structure elucidation.
