CAS#: 138489-18-6

Description: Ro 31-8220 is a PKC-inhibitor, which inhibits stimulated fluid pinocytosis of human PMNs induced by the PKC-activators phorbol myristate acetate (PMA, IC50 = 1.35 x 10(-6) M) or diacylglycerols (OAG, diC8) by 95%. Ro-31-8220 showed the apoptotic effect on HL-60 cells, which was mediated by a well-characterized transduction process of apoptotic signals: i.e., mitochondrial cytochrome c efflux and the activation of caspase-3 in the cytosol. Moreover, the ability of Ro-31-8220 to induce apoptotic activation was completely inhibited by the over-expression of the apoptotic suppressor gene, Bcl-2, in the cells.
