Cytotoxic diterpenoids from Isodon megathyrsus

J Nat Prod. 1994 Oct;57(10):1424-9. doi: 10.1021/np50112a012.

Abstract

A new diterpenoid, megathyrin A, together with three known compounds, rabdocoetsins B, C, and D, were isolated from the leaves of Isodon megathyrsus, and their structures and nmr spectral data were assigned by a combination of one- and two-dimensional nmr techniques. These compounds displayed significant cytotoxic activity.
