METHODS AND RESULTS:
The total alkaloids of T. glandulosissimum and its main component hernandezine were found to be effective for treatment of mice bearing P388 leukemia, S180 ascites and C26 colon cancer.
Although hernandezine inhibited the growth of mouse L1210 cells and human oral cancer KB cells in vitro markedly, its inhibitory effect on normal hemopoietic progenitor cells (CFU-GM) in mice was relatively low.
CONCLUSIONS:
Preliminary results showed that hernandezine blocked cell-cycle transfer from G1 to S phase, and its cytocidal action might be cell cycle specific. In addition, two other components, thalidezine and isothalidezine, isolated from the same plant exerted similar inhibitory effect on L1210 cells. | | Lloydia. 1977 Jul-Aug;40(4):384-94. | | Alkaloids of Thalictrum. XXI. Isolation and characterization of alkaloids from the roots of Thalictrum podocarpum.[Pubmed: 331006] |
METHODS AND RESULTS:
Thirteen alkaloids, hernandezine, thalidezine, N-desmethylthalidezine, isothalidezine, thalistyline, thalistyline methodiiodide, N-desemethylthalistyline, berberine, columbamine, jatrorrhizine, palmatine, thalifendine, magnoflorine and the artifact, 8-trichloromethyldihydroberberine were isolated from the roots of Thalictrum podocarpum Humb. In addition, oxyberberine and thaliglucinone were obtained in very minor amounts and identified by tlc.
CONCLUSIONS:
Of these compounds, N-desmethylthalidezine and isothalidezine are new bisbenzylisoquinoline alkaloids. Sucrose was isolated from the alcoholic extract. Hernandezine, thalistyline, thalidezine, thalistyline methodiiodide and N-desmethylthalistyline were found to possess antimicrobial activity against Mycobacterium smegmatis at concentrations of 100 microgram/ml or less. |
