摘要:
Ophirapstanol trisulfate [1], a new steroid trisulfate related to sokotrasterol trisulfate was isolated from a deep water marine sponge Topsentia ophiraphidites. Compound 1 exhibited significant inhibition in the guanosine diphosphate/G-protein RAS exchange assay. The structure elucidation of 1 and ophirapstanol [2] by nmr spectroscopy is described.
