has role navitoclax A <em>N</em>-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-{[(2<i>R</i>)-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.
