Continuous chemical investigation of the gorgonian coral Pinnigorgia
sp. resulted in the isolation of two new sterols, 5α,6α-epoxy-(22E
) and (22R
). The structures of sterols 1
were elucidated using spectroscopic methods. Sterol 1
displayed inhibitory effects on the generation of superoxide anions and the release of elastase by human neutrophils with IC50
values of 8.65 and 5.86 μM, respectively. The structure of a known metabolite, pubinernoid A (3
), is revised as (+)-loliolide (4
