(Z)-styryl benzylsulfones of formula I are useful as anticancer agents:
wherein
R1 is selected from the group consisting of hydrogen, chloro and nitro;
R2 is selected from the group consisting of hydrogen, lower alkyl, lower alkoxy, chloro, bromo, iodo and fluoro; and
R3 and R4 are independently selected from the group consisting of hydrogen, lower alkyl, nitro, chloro, bromo, iodo and fluoro;
provided that at least one of R1 or R2 is hydrogen.
The corresponding (Z)-styryl benzylsulfides are useful as intermediates in the preparation of the biologically active (Z)-styryl benzyl sulfones.

Pre-treatment with &agr;,&bgr; unsaturated aryl sulfones protects normal cells from the cytotoxic side effects of two classes of anticancer chemotherapeutics. Administration of a cytoprotective sulfone compound to a patient prior to anticancer chemotherapy with a mitotic phase cell cycle inhibitor or topoisomerase inhibitor reduces or eliminates the cytotoxic side effects of the anticancer agent on normal cells. The cytoprotective effect of the &agr;,&bgr; unsaturated aryl sulfone allows the clinician to safely increasing the dosage of the anticancer chemotherapeutic.
