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.

Venetoclax induces Abstract: Venetoclax (formerly ABT-199) was recently approved in the United to induce apoptosis in CLL cells in vitro, ABT-737 possesses poor therapeutic 27 Mar 2019 Recently, venetoclax, an inhibitor of the anti-apoptotic protein BCL-2, has As with ABT-737, venetoclax in combination with azacitidine results 8 Jul 2016 It is important to note; however, that ABT-737 was more potent than ABT-263 at inducing apoptosis in CLL cells, especially in whole blood, since A12500-10 | ABT-199 (Venetoclax) [1257044-40-8]. Synonyms, ABT199; ABT 199; GDC-0199; RG7601. SMILES ABT-737. ABT-737 is a pan-Bcl-2 inhibitor. Venetoclax (formerly ABT-199) is the first to achieve US Food and Drug BH3- mimetic was ABT-737, a small organic molecule tool com- pound that bound Bcl-2 (B-cell lymphoma 2), encoded in humans by the BCL2 gene, is the founding member of ABT-737 is superior to previous BCL-2 inhibitors given its higher affinity for Bcl-2, Bcl-xL and Bcl-w. Abbvie successfully developed the hi ABT-199 (Venetoclax), Bcl-2 inhibitor. (ab217298).

2017. ABT-199 regulates p53/p21 signaling to induce G2/M phase arrest in DOHH2 cells. Representative blots of CDK1/cdc2, cyclin B1, p21 and p53 in DOHH2 cells treated with ABT-199 at 0.1 and 1 μM for 24 h. β-actin is used as the int Since ABT-737 was not suitable for clinical development as an oral agent, its orally bioavailable relative, ABT-263 (navitoclax), was substituted for clinical trials. It is important to note; however, that ABT-737 was more potent than ABT-263 at inducing apoptosis in CLL cells, especially in whole blood, since ABT-263 was highly bound by albumin as compared with ABT-737 [ Vogler et al. 2010 ].

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 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).

Discovery of Venetoclax The binding modes of AbbVie inhibitors are primarily characterized by an electrostatic interaction between the charged acylsulfonamide and an arginine residue on the target

Furthermore, binimetinib significantly increased the sensitivity of CLL cells co-cultured with CD40 ligand (CD40L)-expressing fibroblasts to the BH3-mimetics ABT-737 and Venetoclax (ABT-199) via a mechanism involving down-regulation of Mcl-1 (MCL1) activity and Bim (BCL2L11) and Bcl-xL (BCL2L1) expression. CT26 cells were treated with ABT-737 or S55746 (1 μM for 24 h) and analysed for OCR by Seahorse assay (Fig. 3a, b).
