摘要

(E)-Styryl benzylsulfones useful as antiproliferative agents, including, for example, anticancer agents, are provided according to formula I: wherein: R₁ is selected from the group consisting of halogen, C1-C6 alkoxy, nitro, phosphonato, amino, sulfamyl, carboxy, acetoxy and dimethylamino (C2-C6 alkoxy); and R₂ and R₃ are independently selected from the group consisting of halogen, C1-C6 alkoxy, C1-C6 alkyl, nitro, cyano, hydroxyl, phosphonato, amino, sulfamyl, carboxy, acetoxy, and dimethylamino (C2-C6 alkoxy); provided: R₁ may not be halogen when R₂ and R₃ are both halogen; R₂ may not be 2-halogen when R₃ is 4-halogen; or a pharmaceutically acceptable salt thereof; or formula II: wherein: R₄ is selected from the group consisting of C1-C6 alkoxy, phosphonato, amino, sulfamyl, carboxy, acetoxy and dimethylamino (C2-C6 alkoxy); R₆ is selected from the group consisting of nitro, hydrogen, phosphonato, amino, sulfamyl, carboxy, acetoxy and dimethylamino (C2-C6 alkoxy); and R₇ is selected from the group consisting of halogen, C1-C6 alkoxy, C1-C6 alkyl, nitro, cyano, hydroxy, phosphonato, amino, sulfamyl, carboxy, acetoxy, dimethylamino (C2-C6 alkoxy) and trifluoromethyl; provided R₅ and R₆ may not be hydrogen in the same compound; or a pharmaceutically acceptable salt thereof.
