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. Venetoclax sensitivity was shown to be BCL2-dependent, with decreased lethality in platelets and nanomolar potency in the BCL2-dependent disease CLL [122,126-128]. As a BH3 mimetic, venetoclax is thought to act primarily by binding to BCL2, causing release of sequestered BAX and BAK, thereby leading to MOMP and apoptosis [117,119,129]. 2017-06-02 2015-08-15 BCL-2 is overexpressed in several hematologic malignancies, acting as a key regulator of the intrinsic apoptotic pathway by neutralizing pro-apoptotic molecules and inhibiting apoptosis. 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 (Ki=48 nM, a 500-fold selectivity). ABT-199 (Venetoclax) Chemical Structure CAS NO. 1257044-40-8 ABT-199 is a so-called BH3-mimetic drug, which is designed to block the function of the protein Bcl 2.

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.

( 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).

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).

Given the better tolerance for venetoclax due to a lack of thrombocytopenia development ( 27, 30, 31 ), it is also possible that this agent would be more efficacious in the treatment of SCLC. ABT-737, venetoclax, additional ibrutinib (IB) PI3K inhibitors (IPI-145, and GS-1101 (idelalisib)), and chemotherapy (bendamustine). Among these targeted drugs, MEK1/2 inhibition by binimetinib is effective as a single agent and potentiates the actions of Venetoclax and ABT-737 under conditions that mimic the chronic lymphocytic leukaemia (CLL) tumour 2020-08-13 · Unlike venetoclax, neither ABT-737 nor S55746 decreased OCR. In a second approach, we performed metabolic tracing using labelled 13 C-glutamine, with or without S55746 treatment. 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.

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 ).

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. Pre‐clinical trials of the BH3‐mimetics, ABT‐737, the less bio‐available analogue of ABT‐263 (navitoclax) and Venetoclax (ABT‐199), highlight the potential of targeting the Bcl‐2 family of proteins for the treatment of CLL (Del Gaizo Moore et al, 2007; Balakrishnan et al, 2009). Although targeting the protein directly is challenging, drugs with this mechanism have been developed (e.g., ABT-737, ABT-263, ABT-199), and one (venetoclax, ABT-199) has obtained regulatory approval. These high molecular-weight compounds have significant pharmacological problems and alternatives are still sought.
