The present invention provides a series of 2,3-bis(hydroxymethyl)-4H-benzo[d]pyrrolo-[1,2-a]thiazoles and 1,2-bis(hydroxymethyl)indolizino[6,7-b]indole derivatives and their bis(alkylcarbamates) derivatives. These derivatives were designed as bi-functional DNA cross-linking agents. The in vitro cytotoxicity study of these compounds revealed that they exhibit significant anti-proliferative activity in inhibiting human lymphoblastic leukemia and various solid tumor cell growth. The compounds also exhibit therapeutic efficacy against human breast carcinoma and lung cancer in xenograft model. The compounds generally possess potent antitumor activity to kill various human solid tumors and have high potential for clinical applications.

in vitro was studied. The structure–activity relationship studies revealed that the bis(alkylcarbamates) derivatives are generally more cytotoxic than the corresponding bis(hydroxymethyl) congeners in inhibiting human lymphoblastic leukemia CCRF-CEM and various human solid tumor cell growth in culture. These agents have no cross-resistance to taxol or vinblastine. Studies on the therapeutic effect against
