    • Sulfones of formula I are useful as antiproliferative agents, including, for example, anticancer agents: wherein: Q1 is selected from the group consisting of (a) a phenyl radical according to formula II  wherein R1, R2, R3, R4 and R5 are independently selected from the group consisting of hydrogen, halogen, C1-C6 alkyl, C1-C6 alkoxy, nitro, cyano, carboxyl, hydroxyl, amino, C1-C6 trifluoroalkoxy and trifluoromethyl; (b) an aromatic radical selected from the group consisting of 1-naphthyl, 2-naphthyl and 9-anthryl; and (c) an aromatic radical according to formula III  wherein n1 is 1 or 2, Y1 and Y2 are independently selected from the group consisting of hydrogen, halogen, and nitro, and X1 is selected from the group consisting of oxygen, nitrogen, sulfur and and Q2 is selected from the group consisting of (d) a phenyl radical according to formula II, as defined above; (e) an aromatic radical selected from the group consisting of 1-naphthyl, 2-naphthyl and 9-anthryl; (f) an aromatic radical according to formula IV  wherein n1 is 1 or 2, Y3 and Y4 are independently selected from the group consisting of hydrogen, halogen, and nitro, and X2, X3 and X4 are independently selected from the group consisting of carbon, oxygen, nitrogen, sulfur and  provided that not all of X2, X3 and X4 may be carbon; and (g) 1-piperazinyl; provided that at least one of Q1 or Q2 is other than a phenyl radical according to formula II; or a pharmaceutically acceptable salt thereof. Sulfones of formula V are also useful as antiproliferative agents, including, for example, anticancer agents: wherein: X is sulfur or oxygen; Ya and Yb are independently selected from the group consisting of hydrogen, halogen, and nitro; and R1-R5 are defined as above; or a pharmaceutically acceptable salt thereof.
    • 式I的砜可用作抗增殖剂,包括例如抗癌剂:其中:Q1选自(a)根据式II的苯基,其中R 1,R 2,R 3,R 4和R 5独立地选自 由C 1 -C 6烷基,C 1 -C 6烷氧基,硝基,氰基,羧基,羟基,氨基,C 1 -C 6三氟烷氧基和三氟甲基组成的组;(b)选自1- 萘基,2-萘基和9-蒽基; 和(c)根据式III的芳族基团,其中n1为1或2,Y1和Y2独立地选自氢,卤素和硝基,X1选自氧,氮,硫,Q2为 选自(d)如上定义的根据式II的苯基;(e)选自1-萘基,2-萘基和9-蒽基的芳族基团;(f)芳族 基团,其中n1为1或2,Y3和Y4独立地选自氢,卤素和硝基,X2,X3和X4独立地选自碳,氧,氮,硫和 只要不是所有的X2,X3和X4都可以是碳; (g)1-哌嗪基;条件是Q1或Q2中的至少一个不是根据式II的苯基;或其药学上可接受的盐。式V的砜也可用作抗增殖剂,包括例如 抗癌剂:其中:X为硫或氧; Ya和Yb独立地选自氢,卤素和硝基; 和R 1 -R 5如上定义;或其药学上可接受的盐。
