摘要: Apoptogenic and DNA damaging effects of chelidonine (CHE) sanguinarine (SAN), two structurally related benzophenanthridine alkaloids isolated from Chelidonium majus L. (Papaveraceae), were compared. Both induced apoptosis in human acute T-lymphoblastic leukaemia MT-4 cells. Apoptosis induction by CHE SAN these cells was accompanied caspase-9 -3 activation an increase the pro-apoptotic Bax protein. An elevation percentage possessing caspase-3 active form after their treatment with or parallel to a corresponding fraction apoptotic The involvement mitochondria both supported cytochrome C cytosol, accompanying decrease content mitochondrial fraction. At same time, under study differed drastically cell cycle phase-specific effects, since only arrested G(2)/M phase. It shown earlier, that CHE, contrast SAN, does not interact directly DNA. This fact is line detected COMET assay. Nevertheless, apoptosis-inducing activity even slightly exceeded SAN.
