This class of putative anticancer agents invariantly contains an acylsulfonamide core. We have designed and synthesized a series of novel quinazoline-based inhibitors of Bcl-2 and Bcl-x(L) that contain a heterocyclic alternative to the acylsulfonamide. These compounds exhibit submicromolar, mechanism-based activity in human small-cell lung carcinoma cell lines in the presence of 10% human serum. This comprises the first successful demonstration of a quinazoline sulfonamide core serving as an effective benzoylsulfonamide bioisostere. Additionally, these novel quinazolines comprise only the second known class of Bcl-2 family protein inhibitors to induce mechanism-based cell death.
