Maxonine, a novel alkaloid from Simira maxonii

Abstract

A novel alkaloid, maxonine, with an indole-pyrido-naphthyridine skeleton, has been isolated from . Its structure was elucidated on the basis of 2D NMR spectral data. A novel alkaloid, maxonine (1), with an indolepyrido-naphthyridine nucleus, has been isolated from . Its structure was established on the basis of 2D NMR spectral data. Compound 1 showed an unexpected bathochromic shift in the UV spectrum with HCl.
