Aplysiallene, a new bromoallene as an Na, K-ATPase inhibitor from the sea hare, Aplysia kurodai.

ABSTRACT

A new bromoallene metabolite, named aplysiallene, was isolated from the Japanese sea hare, Aplysia kurodai, as an Na, K-ATPase inhibitor. Its structure was elucidated by spectroscopic methods. The known metabolites, laurinterol and debromolaurinterol, isolated from this animal were also evaluated for their Na, K-ATPase inhibitory activity.
