Logáil Isteach / Cláraigh
A molecular modeling study of two alkaloids, tubulosine and psychotrine, isolated from the sap of Pogonopus speciosus, and other related ipecac alkaloids, showed that these flexible alkaloids favor a nonplanar structure. The biologically active compounds had conformations with a similar angle

Logáil Isteach / Cláraigh
From the antitumor-bioactive sap of Pogonopus speciosus, tubulosine [1] was isolated, by activity-directed fractionation using the brine shrimp lethality test, as the major antitumor constituent. 1H-nmr assignments, obtained from HETCOR and COSY, and X-ray crystallographic results are reported for
1',2',3',4'-tetradehydrotubulosine, a cytotoxic alkaloid from Pogonopus speciosus.

Logáil Isteach / Cláraigh
Bioassay-guided phytochemical investigation of the stems of Pogonopus speciosus, using human oral epidermoid carcinoma (KB) cells as a monitor, led to the isolation of a novel alkaloid, 1',2', 3',4'-tetradehydrotubulosine (1), along with tubulosine (2) and psychotrine (3) as bioactive constituents.
