alpha-Piperidine-beta-sulfone hydroxamate derivatives were explored that are potent for matrix metalloproteinases (MMP)-2, -9, and -13 and are sparing of MMP-1. The investigation of the beta-sulfones subsequently led to the discovery of hitherto unknown alpha-sulfone hydroxamates that are superior to the corresponding beta-sulfones in potency for target MMPs, selectivity vs MMP-1, and exposure when dosed orally. alpha-Tiperidine-alpha-sulfone, hydroxamate 35f (SC-276) was advanced through antitumor and antiangiogenesis assays and was selected for development. Compound 35f demonstrates excellent antitumor activity vs MX-1 breast tumor in mice when dosed orally as monotherapy or in combination with paclitaxel.
