Isolation and structures of attenols A and B. novel bicyclic triols from the Chinese bivalve Pinna attenuata
Novel bicyclic triols, attenols A (1) and B (2), were isolated from the Chinese bivalve Pinna attenuata. The absolute stereostructures of 1 and 2 were determined by spectroscopic analysis and the modified Mosher’s method. These attenols exhibited moderate cytotoxicity against P388 cells.
