Article Abstract

Meloyunnanines A-C, three alkaloids with an unprecedented skeleton, were isolated from fruits of . The structures featuring a caged-6/6/5/6/5/5 ring system were elucidated by the analysis of comprehensive spectroscopic and X-ray data. Biosynthetically, meloyunnanines A-C were assigned to monoterpenoid quinoline alkaloids (MQAs), derived from monoterpenoid indole alkaloids through oxidation and rearrangement. These compounds together with three known MQAs were evaluated for their neurotrophic activity and scandine -oxide exhibited significant effect.
