title: Okaramines N, O, P, Q and R, new okaramine congeners, from Penicillium simplicissimum ATCC 90288.
abstract: Five new okaramine congeners, okaramines N, O, P, Q, and R, were isolated from Penicillium simplicissimum ATCC 90288. Their structures were determined by an analysis of spectroscopic data. The insecticidal activity of these new okaramines was evaluated against silkworms.
