Synthesis of the amaryllidaceae alkaloid, lycorine

Journal of the Chemical Society, Chemical Communications, 1975
A key intermediate for the total synthesis of lycorine has been prepared in racemic form; the optically pure form of this epoxylycorinane lactam, obtained from lycorine, has been reconverted into the alkaloid.

Antiinflammatory effects of lycorine and haemanthidine

Phytotherapy Research, 1998
The antiinflammatory effects of lycorine and haemanthidine which were isolated from Sternbergia clusiana (Ker-Gawl.) Ker-Gawl ex Sprengel growing in Turkey were evaluated in mice by the carrageenan-induced oedema test. Antiinflammatory activities of lycorine and haemanthidine were higher than that of indomethacin. © 1998 John Wiley & Sons, Ltd.

[Various sensitivities of yeasts to lycorine].

Bollettino della Societa italiana di biologia sperimentale, 1990
Lycorine, an Amaryllidaceae alkaloid, is a powerful inhibitor of growth in higher plants and algae. Thirty-one strains of yeasts, belonging to different genera and species, were screened to study the effect of lycorine on their growth. The strains were incubated at 25 degrees C in a 2% glucose medium with different concentrations of lycorine (10, 50 ...
