TAILIEUCHUNG - Báo cáo khoa học: Strong cytotoxic effect of the bradykinin antagonist BKM-570 in ovarian cancer cells – analysis of the molecular mechanisms of its antiproliferative action

The standard chemotherapy for epithelial ovarian cancer (EOC) patients is currently a combination of taxane and platinum. However, most EOC patients still suffer relapses, and there is an immediate need for the devel-opment of novel and more effective therapeutic modalities against this deadly disease. | IFEBS Journal Strong cytotoxic effect of the bradykinin antagonist BKM-570 in ovarian cancer cells - analysis of the molecular mechanisms of its antiproliferative action Stephanie Jutras1 2 Magdalena Bachvarova2 Mamadou Keita1 2 Jean-Loup Bascands3 4 Anne-Marie Mes-Masson5 6 John M.

However most EOC patients still suffer relapses and there is an immediate need for the development of novel and more effective therapeutic modalities against this deadly disease. Recently the nonpeptide bradykinin BK antagonist pentafluorocinnamoyl- o-2 6-dichlorobenzyl -l-tyrosine-N- 4-amino- tetramethyl-piperidyl amide BKM-570 was shown to cause impressive growth inhibition of lung and prostate tumors displaying superior in vivo inhibitory effects than convential chemotherapeutic drugs.
