ABT 263

Description

ABT-263 (923564-51-6) is a potent and selective Bcl-2 family inhibitor / BH3 domain mimetic which binds to Bcl-2, Bcl-xL?and Bcl-w (Ki<1 nM). A useful tool compound which has shown interesting results in various cancer clinical trials.2?Synergizes with deoxyglucose and other agents, inducing apoptosis in cancer cells in a xenograft mouse model.3?A novel senolytic agent, inducing apoptosis preferentially in senescent cells in a cell type-restricted manner.4

The Uses of ABT 263

A novel inhibitor of antiapoptotic BCL-2 proteins; a new promising anticancer drug candidate.

The Uses of ABT 263

ABT-263 (Navitoclax) is a potent inhibitor of Bcl-xL, Bcl-2 and Bcl-w with Ki of ≤ 0.5 nM, ≤1 nM and ≤ 1 nM, respectively.

What are the applications of Application

ABT 263 is an inhibitor of antiapoptotic Bcl-2 proteins

Definition

ChEBI: Navitoclax is a N-sulfonylcarboxamide resulting from the formal condensation of the carboxy group of 4-{4-[(4'-chloro-4,4-dimethyl-3,4,5,6-tetrahydro[biphenyl]-2-yl)methyl]piperazin-1-yl}benzoic acid with the amino group of 4-{[(2R)-4-(morpholin-4-yl)-1-(phenylsulfanyl)butan-2-yl]amino}-3-[(trifluoromethyl)sulfonyl]benzenesulfonamide. It is a BH3-mimetic drug which targets the anti-apoptotic B-cell lymphoma-2 (BCL-2) family proteins, including BCL-2, BCL-xL, and BCL-w, and induces apoptosis in cancer cells. Currently under clinical investigation as treatment for solid tumors and hematologic malignancies. It has a role as a B-cell lymphoma 2 inhibitor, an apoptosis inducer and an antineoplastic agent. It is a member of piperazines, a member of monochlorobenzenes, a member of morpholines, an aryl sulfide, a N-sulfonylcarboxamide, a sulfone, an organofluorine compound, a secondary amino compound and a tertiary amino compound.

Mechanism of action

ABT‐263 exerts its senolytic activity in senescent tumor cells by inhibiting BCL‐XL's interaction with BAX. ABT‐263 is a BH3 mimetic that inhibits anti‐apoptotic BCL‐2 family proteins by impeding their ability to bind pro‐apoptotic proteins, such as BAK and BAX. BCL‐2 and BCL‐XL are the primary targets of ABT‐263 in cancer cells.
