Venetoclax (ABT-199, GDC-0199) is a selective inhibitor of Bcl-2 with a K i of 0.01 nM in cell-free assays. Compared to Bcl-XL and Bcl-W more than 4800 times more selective, no inhibitory activity against McL-1[1].
ABT-199 cell killing was selective and mechanism dependent, BCL2high status is thus a potential predictive marker for sensitivity to ABT-199[1].BIM binding to BCL2 correlates with ABT-199 response and further showed that knockout of BIM results in decreased ABT-199 sensitivity. Eexpression of B-cell genes as enriched in ABT-199-sensitive myeloma, although no single gene consistently delineated sensitive and resistant cells[4]. In the ABT-199-resistant OCI-AML3 cell line, CXCL12 promoted an increase in the proportion of cells expressing high levels of embryonic stem cell core transcription factors abrogated by CD44 knockdown[7].The T-ALL cell line LOUCY, which shows a transcriptional program related to immature T-ALL, exhibited high in vitro and in vivo sensitivity for ABT-199 in correspondence with high levels of BCL-2. In addition, ABT-199 showed synergistic therapeutic effects with different chemotherapeutic agents[3].When performed a genome-wide CRISPR knockout screen and found that inactivation of genes involved in mitochondrial translation restored sensitivity to ABT-199 in resistant AML cells. Pharmacologic inhibition of mitochondrial protein synthesis with antibiotics that target the ribosome, including tedizolid and doxycycline, effectively overcame ABT-199 resistance[6].
VU661013 is a novel, potent, selective MCL1 inhibitor. VU661013 was safely combined with ABT-199 for synergy in murine models of AML[3].ABT-199 and 5-Aza act synergistically to kill AML cells in vitro and display combinatorial antitumor activity in vivo[5]. Treatment with ABT-199 alone and in combination is well tolerated, with the most common side effects being neutropenia, infection, and gastrointestinal toxic effects[2].

ABT-199 细胞杀伤具有选择性和机制因此,BCL2high 状态是对 ABT-199[1] 敏感性的潜在预测标志物。BIM 与 BCL2 的结合与 ABT-199 反应相关,并进一步表明敲除 BIM 会导致 ABT-199 降低灵敏度。 B 细胞基因的表达在 ABT-199 敏感性骨髓瘤中富集,尽管没有单个基因始终如一地描述敏感和耐药细胞[4]。在 ABT-199 抗性 OCI-AML3 细胞系中,CXCL12 促进表达高水平胚胎干细胞核心转录因子的细胞比例增加,CD44 敲低[7]。T-显示与未成熟 T-ALL 相关的转录程序的 ALL 细胞系 LOUCY 对 ABT-199 表现出高体外和体内敏感性,与高水平的 BCL-2 相对应。此外,ABT-199 显示出与不同化疗药物的协同治疗效果[3]。在进行全基因组 CRISPR 敲除筛选时,发现参与线粒体翻译的基因失活可恢复对 ABT-199 的敏感性在抗性 AML 细胞中。使用靶向核糖体的抗生素（包括泰地唑胺和多西环素）抑制线粒体蛋白质合成,有效克服了 ABT-199 耐药性[6]。
