  A novel triazole derivative of betulinic acid induces extrinsic and intrinsic apoptosis in human leukemia HL-60 cells

  摘要：

  In an attempt to arrive at more potent cytotoxic agent than the bioactive natural product betulinic acid, influence of small structural modifications of its 1, 2, 3 triazole derivatives tethered at C-28 and both C3, C-28 using click chemistry approach has been studied. The chemically characterized triazoles have been screened for in vitro cytotoxicity against four human cancer cell lines HL-60, MiaPaCa-2, PC-3 and A549 which has allowed to identify triazole derivative 28{1N (4-fluoro phenyl)-1H-1, 2, 3-triazol-4-yl} methyloxy betulinic ester having better potency profile than the parent compound with IC50 values in the range of 5-7 mu M. It caused disruption of mitochondrial membrane potential, rendered Bcl-2 cleavage, Bax translocation and decrease Bcl-2/Bax ratio. These events are accompanied by activation of caspases -9, similar to 3, which cleave the PARP-1. It also induces caspase-8, which is involved in extrinsic apoptotic pathway. Therefore, it induces apoptosis through both intrinsic and extrinsic pathways in human leukemia HL-60 cells. (C) 2015 Elsevier Masson SAS. All rights reserved.

  alpha-Santonin derived new series of 1,2,3-triazoles synthesized through Azide Alkyne Huisgen 1,3-dipolar cycloaddition reaction between substituted aryl azide and a propargylated alpha-desmotrosantonin were bio-evaluated for their diminutive effect on ConA induced T-cell and LPS induced B-cell proliferation. Interestingly, most of the synthesized compounds showed better immunosuppressant activity than alpha-santonin. Triazole derivatives 9, 10, 17, 18, 29, and 30 displayed significant diminutive effect on cell proliferation. Compounds 12 and 13 were found selective against ConA T-cell proliferation exhibiting >90% inhibition at 1 x 10(-6) M concentration. The present study resulted in identification of several triazole derivatives as effective immunosuppressive agents. (C) 2012 Elsevier Masson SAS. All rights reserved.
