Venetoclax (ABT-199; GDC-0199) is a highly potent, selective and orally bioavailable Bcl-2 inhibitor with a Ki of less than 0.01 nM. Venetoclax induces 

IC50 values ranged from 192 nM (the pre-B cell line Hal-01) to 10 μM (Nalm-6, K562 and HL-60). (ABT-737, Navitoclax, and Venetoclax) target this binding and induce apoptosis. Venetoclax avoids Navitoclax's adverse effects on platelets by specifically targeting BCL-2 instead of multiple BCL proteins. EFFECTS ON TARGETS Venetoclax sensitizes cells for apoptosis. When active pro-apoptotic Unlike ABT-737, venetoclax does not neutralize BCL-X L, , which cooperates with MCL-1 to tether BAK .

The need to develop a BCL-2 inhibitor sparing BCL-X L and platelets sparked the discovery and development of ABT-199 (venetoclax) . Suppression of apoptosis by expression of antiapoptotic BCL2 family members is a hallmark of acute myeloblastic leukemia (AML). Induced myeloid leukemia cell differentiation protein (MCL1), an antiapoptotic BCL2 family member, is commonly upregulated in AML cells and is often a primary mode of resistance to treatment with the BCL2 inhibitor venetoclax.

Nevertheless, both genetic and pharmacologic inactivation of BCL-2 sharply increased the antileukemic activity of the PI3K inhibitor GDC-0980, demonstrating that BCL-X L disruption is not required for synergistic antileukemic interactions in AML cells. 2016-04-21 · generation BH3 mimetic venetoclax (ABT-199/GDC-0199) is a BCL-2–selective inhibitor that retains robust activity against hematologic tumor cells (i.e., CLL) but spares platelets, resulting in a wider therapeutic index (22). Similar to ABT-737, proapop-totic effects have been observed with venetoclax in HMCLs and Pharmacological inhibition of BCL2 or JAK1/2 prior to alloSCT in mice with Venetoclax or Ruxolitinib respectively resulted in rapid depletion of recipient NK cells. A significant proportion (>80%) of alloSCT recipient mice pre-treated with either drug developed full donor cell engraftment after reduced intensity conditioning, did not develop GVHD, and retained potent anti-tumour effects abt-737 It was discovered as the first high-affinity inhibitor of BCL-2 family proteins by using nuclear magnetic resonance (NMR)-based screening ( 41 ).

ABT-737, ABT-263 (Navitoclax) and ABT-199 (Venetoclax) are under intensive preclinical and clinical investigation as treatments for hematologic and other malignancies. These small molecules mimic pro-death B-cell lymphoma-2 (Bcl-2) Homology 3 (BH3) domain-only proteins. They also bear a structural resemblance to certain sigma (σ) receptor ligands.

Primary AML blasts were treated with cobimetinib and venetoclax alone or in combination at 0.1 μM for 5 days in LSC medium to maintain the immature state of the leukemia cells.24 Cobimetinib alone induced minimal cell death (specific apoptosis, 6.7 ± 5.9%), which was significantly enhanced when the drug was given in combination with venetoclax (27.7 ± 20.2%, P=0.001) (Figure 2A, left). Venetoclax plus LDAC demonstrates clinically meaningful improvement in remission rate and OS vs LDAC alone, with a manageable safety profile. Results confirm venetoclax plus LDAC as an important frontline treatment for AML patients unfit for intensive chemotherapy. This trial was registered at www.clinicaltrials.gov as #NCT03069352.

CT26 cells were treated with ABT-737 or S55746 (1 μM for 24 h) and analysed for OCR by Seahorse assay (Fig. 3a, b). Unlike venetoclax, neither ABT-737 nor S55746 decreased OCR. Description: ABT-737 is a novel, potent, selective and orally available BH3 mimetic inhibitor of Bcl-xL, Bcl-2 and Bcl-w with EC50 of 78.7 nM, 30.3 nM and 197.8 nM in enzymatic assays, respectively. It does not inhibit Mcl-1, Bcl-B or Bfl-1 etc. It is currently in Phase 2 clinical trial for cancer treatment.
