体外研究：

S55746 is a potent inhibitor of BCL-2 (Ki=1.3 nM). S55746 potently induces RS4;11 cell killing after 72 h of treatment with an IC50 of 71.6 nM. Interestingly, S55746 exhibits a much weaker activity in H146 (IC50=1.7 μM), a BCL-XL-dependent cell line, which expresses a low level of BCL-2 and high level of BCL-XL whereas ABT-263, which targets BCL-2 and BCL-XL, induces equivalent cell killing in both RS4;11 and H146 (41.5 nM and 49.7 nM, respectively). S55746-induced apoptosis in RS4;11 is mediated in part by the BAX effector protein since PARP cleavage is markedly inhibited in BAX-deficient RS4;11 cells. S55746 is shown to strongly induce apoptosis in BCL-2-dependent FL5.12 cells with a minor effect in BCL-XL-dependent FL5.12 cells.
