(16E,20β)-16,17-ジデヒドロ-9,17-ジメトキシコリナン-16-カルボン酸メチル 化学特性,用途語,生産方法
説明
This alkaloid has been isolated from Mitragyna speciosa Korth, and is amorphous
although it yields a series of crystalline salts and derivatives. The hydrochloride
crystallizes as colourless leaflets from EtOH-Et20 with m.p. 243°C; the picrate
forms thin, orange-red needles, m.p. 223-4°C and the methiodide is a pale
yellow powder which, although amorphous, has a sharp melting point of
21 1. 5°C. The alkaloid also forms compounds with acetic acid, m.p. 142°C,
decomposing at 175-6°, and with trichloroacetic acid, m.p. 157°C.
Mitragynine exerts a general depressant effect on plain muscle and facilitates
the passage of autonomic impulses. It is, however, ineffective against pathogenic
organisms.
