  Design and Synthesis of 3‘- and 5‘-O-(3-Benzenesulfonylfuroxan-4-yl)-2‘-deoxyuridines:  Biological Evaluation as Hybrid Nitric Oxide Donor−Nucleoside Anticancer Agents

  摘要：

  A group of 3'-O- and 5'-O-(3-benzenesulfonylfuroxan-4-yl)-2'-deoxyuridines possessing a variety of substituents (H, Me, 1, F, CF3) at the C-5 position of the nucleoside moiety were synthesized for evaluation as hybrid anticancer agents that have the ability to simultaneously release cytotoxic nitric oxide ((NO)-N-.). Incubation of these nitric oxide donor-nucleoside conjugates in the presence of 18 MM L-cysteine released a high percentage of (NO)-N-. (21-48% at 1 h; 37-86% at 16 h). The release of (NO)-N-. in the absence of the thiol cofactor was negligible. These hybrid (NO)-N-. donor-nucleosides exhibited high cellular toxicity (CC50 = 10(-6)-10(-8) M range) against a battery of tumor cell lines (143B-LTK, 14313, EMT-6, KBALB-STK, and KBALB) and normal human fibroblasts (Hs578Bst). No differences in cytotoxicity between nontransfected (143B, KBALB) and the corresponding transfected (143B-LTK, KBALB-STK) cancer cell lines possessing the herpes simplex virus type 1 (HSV-1) thymidine kinase gene (TK+) were observed, indicating that expression of the viral TK enzyme did not provide a gene therapeutic effect.
