Design, Synthesis, and Biological Evaluation of (E)-Styrylbenzylsulfones as Novel Anticancer Agents
摘要:
Cell cycle progression is regulated by cyclins and cyclin-dependent kinases, which are formed at specific stages of the cell cycle and regulate the G1/S and G2/M phase transitions, employing a series of "checkpoints" governed by phosphorylation of their substrates. Tumor development is associated with the loss of these checkpoint controls, and this provides an approach for the development of therapeutic agents that can specifically target tumor cells. Here, we describe the synthesis and SAR of a novel group of cytotoxic molecules that selectively induce growth arrest of normal cells in the G1 phase while inducing a mitotic arrest of tumor cells resulting in selective killing of tumor cell populations with little or no effect on normal cell viability. The broad spectrum of antitumor activity in vitro and xenograft models, lack of in vivo toxicity, and drug resistance suggest potential for use of these agents in cancer therapy.

Pre-treatment with one or more compounds of formula (I), as described herein, protects normal cells from the toxic side effects of ionizing radiation. Administration of one or more radioprotective compounds of formula (I) to a patient prior to anticancer radiotherapy reduces the cytotoxic side effects of the radiation on normal cells. The radioprotective effect of one or more compounds of formula (I) allows for the safe increase the dosage of anticancer radiation. Amelioration of toxicity following inadvertent radiation exposure may also be mitigated with administration of one or more compounds of formula (I).
