(2S)-2-Dimethylamino-N-[(3R,4S,7S)-5,8-dioxo-3-phenyl-7-phenylmethyl-2-oxa-6,9-diazabicyclo[10.2.2]hexadeca-10,12,14(1),15-tetren-4-yl]-3-methylbutanamide

Description

The second peptide alkaloid isolated from the roots of Ceanothus integerrimus Hook et Am., this base also crystallizes from CHCl3-light petroleum as colourless needles. Like the preceding alkaloid it is laevorotatory with [α]²⁰_D - 164° (c 0.2, CHCI 3). The ultraviolet spectrum is identical with that of integerrenine. The structure has likewise been elucidated from the mass spectrum.

Definition

ChEBI: Integerressine is a cyclic peptide.
