Antimicrotubule properties of benzophenanthridine alkaloids

Biochemistry, 1993
Chelidonine, sanguinarine, and chelerythrine are natural benzophenanthridine alkaloids that inhibit taxol-mediated polymerization of rat brain tubulin in the micromolar range. Chelidonine is a weak, competitive inhibitor of colchicine binding to tubulin but does not inhibit podophyllotoxin binding.

Benzophenanthridine alkaloids from Zanthoxylum rhoifolium

Phytochemistry, 1997
A novel benzophenanthridine alkaloid, named zanthoxyline, was isolated from the bark of Zanthoxylum rhoifolium, together with the known compounds, dihydronitidine, 6-oxynitidine and skimmianine. The structure of the new compound was elucidated on the basis of spectroscopic investigations and elemental analysis.

Isochelidonine, a benzophenanthridine alkaloid from chelidonium majus

Phytochemistry, 1992
Abstract A new benzophenanthridine alkaloid, isochelidonine, has been isolated from Chelidonium majus and characterized mainly by spectral analysis. Isochelidonine is the first benzophenanthridine alkaloid from the Papaveraceae with C-10,11 substituents.
