Prodrugs of a CBI-bearing CC-1065analogue were synthesized. Antitumor activity of the compounds was evaluated against tumor cells in vitro and in mouse tumor models. Compounds 1 and 7, bearing methylpiperazine and DHA moieties, respectively, showed significant antitumor activity in both the L1210 leukemia and Lewis lung carcinoma mouse tumor models. For the carbamate prodrugs 1-4 and 6, there is a

We have synthesized a conjugate of cis-4,7,10,13,16,19-docosahexenoic acid (DHA) and 10-hydroxycamptothecin (HCPT), DHA-HCPT. The antitumor activity of DHA-HCPT was evaluated in vitro against L1210 leukemia cells and in experimental animal tumor models including L1210 leukemia, Lewis lung carcinoma, and colon 38 adenocarcinoma. DHA-HCPT showed a greatly improved antitumor efficacy compared to HCPT. (c) 2005 Elsevier Ltd. All rights reserved.
