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 ). In a preclinical study, ABT-737, which can effectively trigger Bax/Bak-mediated apoptosis, induced AML cell apoptosis in vitro , and the same activity was demonstrated in a murine xenograft model in vivo ( 42 – 44 ).

Structure, properties, spectra, suppliers and links for: Venetoclax, 1257044-40-8. 2021-01-06 · Venetoclax (ABT-199, GDC-0199) is a Bcl-2-selective inhibitor with K i of 0.01 nM in cell-free assays, >4800-fold more selective versus Bcl-xL and Bcl-w, and no activity to Mcl-1. Venetoclax is reported to induce cell growth suppression, apoptosis, cell cycle arrest, and autophagy in triple negative The venetoclax/azacitidine combination showed less potency against AML cell lines in vitro compared to ABT-737, but similar potency against primary AML and MDS samples tested ex vivo (23, 24).

( 26 Feb 2016 William Wierda, MD, PhD from the University of Texas MD Anderson Cancer Center, Houston, TX talks about venetoclax (ABT-199), which is a William Wierda, MD, PhD from the University of Texas MD Anderson Cancer Center, Houston, TX talks about venetoclax (ABT-199), which is a Bcl-2 inhibitor. ABT-199 is an orally bioavailable, second-generation BH3-mimetic that specifically and potently inhibits BCL-2 (Ki<0.10 nM), highly selective over BCL- xL ABT-199, developed through a structure-based reverse engineering process, is a novel and specific inhibitor of B-cell lymphoma/leukemia 2 (BCL-2) Venetoclax is a targeted therapy that can make lymphoma cells undergo apoptosis (programmed cell death).

Subsequent in vitro studies showed activity against myeloma [ 46, 47 ], acute leukemia [ 48, 49 ], and lymphoma. ABT-737 is a pan-Bcl-2 inhibitor. IC50 values ranged from 192 nM (the pre-B cell line Hal-01) to <10 μM (Nalm-6, K562 and HL-60).
2015-11-20 · Therefore, BCL-X L inhibition could speed up this molecular clock and lead to decreased platelet survival—the mechanism implicated in ABT-737/ABT-263-induced thrombocytopenia. 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.

However, increased mortality was seen in the venetoclax group, mostly because of an increased rate of infections, highlighting the importance of appropriate selection of patients for this treatment option.
