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 microenvironment

16, 17 Den andra generationens föreningen ABT-199 / venetoklax / venclexta  ABT-737 is a small molecule inhibitor of BCL-2, BCL-X L, and BCL-w [ 45 ]. ABT-737 showed in vitro activity against lymphoma and small cell carcinoma cells. 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). ABT-737, ABT-263 (Navitoclax) and ABT-199 (Venetoclax) are under intensive preclinical and clinical investigation as treatments for hematologic and other malignancies.

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. 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).

Venetoclax (Venclexta®) is a first-in-class selective Bcl-2 inhibitor approved for the treatment of chronic lymphociytic leukemia (1). Venetoclax1(Figure 1) disrupts blockage of the intrinsic apoptosis pathway mediated by Bcl-2 family proteins.

These small molecules mimic pro-death B-cell lymphoma-2 (Bcl-2) Homology 3 (BH3) domain-only proteins. Venetoclax (Venclexta®) is a first-in-class selective Bcl-2 inhibitor approved for the treatment of chronic lymphociytic leukemia (1). Venetoclax1(Figure 1) disrupts blockage of the intrinsic apoptosis pathway mediated by Bcl-2 family proteins. CT26 cells were treated with ABT-737 or S55746 (1 μM for 24 h) and analysed for OCR by Seahorse assay (Fig.

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.

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 microenvironment 2015-11-01 The BH3‐mimetic BCL2 inhibitors ABT‐737, 35 navitoclax, 37 and venetoclax 43 consistently demonstrate augmentation of efficacy for DNA damaging chemotherapy, 22, 43, 56 monoclonal antibodies, 38 tyrosine kinase inhibitors, 57-59 steroids, 60 and proteasome inhibitors 13, 61 both in vitro 14, 51, 57-59 and in vivo 13, 37, 43, 51, 56, 61 model systems. Multiple myeloma (MM) is an incurable plasma cell (PC) dyscrasia with a 5-year overall survival of 50.7% that is estimated to currently affect 124,733 people in the United States.1 Despite recent advances that have improved outcomes, MM inevitably becomes refractory to therapy, so clinicians must rely on a variety of treatment options for long-term disease management. 2018-05-11 Acute Myeloid Leukaemia is a devastating disease that continues to have a poor outcome for the majority of patients. In recent years, however, a number of drugs have received FDA approval, following on from successful clinical trial results. This parallels the characterization of the molecular landscape of Acute Myeloid Leukaemia (AML) over the last decade, which has led to the development of 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 microenvironment ABT-737, ABT-263 (Navitoclax) and ABT-199 (Venetoclax) are under intensive preclinical and clinical investigation as treatments for hematologic and other malignancies.
