摘要: Solamargine, solasodine and khasianine steroidal alkaloids are utilized to determine the role of carbohydrate moiety in mechanism apoptosis. The C3 side chain solamargine, contains 4'Rha-Glc-Rha2', 4'Rha-Glc H, respectively. Solamargine possessed potent cytotoxicity human hepatoma cells, while was greatly diminished. Nevertheless, only solamargine could induced "sub-G1" apoptotic feature flowcytometry. Thus, 2'Rha may play a crucial triggering cell death by In addition, molecular modeling indicated that adjacent rigid steroid structure, drastically changed dihedral angle glycosidic bond. regulations TNFR I II expression different moieties were also distinct. It implied might alter binding specificity receptors consequently regulate gene manners.
