Venetoclax (ABT-199, GDC-0199)是一种Bcl-2选择性抑制剂，无细胞试验中Ki为<0.01 nM，比作用于Bcl-xL和Bcl-w选择性高4800倍以上，对Mcl-1没有抑制活性。有研究证明 Venetoclax 在三阴性乳腺癌 MDA-MB-231 细胞中诱导细胞生长抑制，凋亡，细胞周期停滞和自噬。Phase 3。

| 体内研究 | After a single oral dose of 12.5 mg per kg body weight in xenografts derived from RS4;11 cells (ALL), Venetoclax (ABT-199) causes a maximal tumor growth inhibition (TGImax) of 47% (P<0.001) and tumor growth delay (TGD) of 26% (P<0.05). Treatment of established xenografted (a mouse xenograft model of the T-ALL cell line LOUCY) tumors with Venetoclax (ABT-199) 100 mg/kg for 4 days results in a significant reduction of leukemic burden. |
| 体外研究 | Venetoclax (ABT-199) potently kills FL5.12-BCL-2 cells (EC50=4 nM), Venetoclax (ABT-199) shows much weaker activity against FL5.12-BCL-XL cells (EC50=261 nM). ABT-199 also shows selectivity in cellular mammalian two-hybrid assays, where it disrupts BCL-2-BIM complexes (EC50=3 nM) but is much less effective against BCL-XL-BCL-XS (EC50=2.2 μM) or MCL-1-NOXA complexes. |
