  Design, Synthesis and Evaluation of Imidazolylmethyl Carbamate Prodrugs of Alkylating Agents

  摘要：

  Two approaches to prodrugs of alkylating agents based on an imidazolylmethyl carbamate nucleus were explored. A 2-azido analogue (3) of the bis-carbamate carmethizole (1) displayed similar aerobic cytotoxicity to 1 in a panel of human and murine cell lines. Approaches to the 2-amino and 2-carbamoyl analogues are described. In the second approach an imidazolylmethanol was used as a 'trigger' linked via a carbamate to the alkylating agent N,N-bis(2-chlorethyl)amine (BCEA). Nitroimidazole and methylsulphinylimidazole carbamate prodrugs 6-8 were 5-20-fold less toxic than BCEA. Despite this deactivation in the prodrug form, little increase in cytotoxicity was observed under hypoxia. The data suggest that BCEA released on bioreduction is not sufficiently potent to contribute significant additional cytotoxicity. (C) 2000 Elsevier Science Ltd. All rights reserved.

  Compounds of formula (I) or (II), wherein X represents H, C1-6 alkyl or C1-6 alkoxy, said alkyl or alkoxy being optionally substituted with one or more groups; a is 0,1,2,3 or 4; Y represents H or C1-6 alkyl; 1, 2 or 3 of the members Z of the 5-membered aromatic ring are independently selected from -O-, -S-, -N= or -NR-, where R is H or C1-6 alkyl optionally substituted with one or more of groups; and E represents a moiety such that EH is an amine; provided that in formula (I) if a = 0 then Y≠H, are provided along with a method of selecting desired protecting groups by measuring the fragmentation rates of compounds of formula (I) or (II) when the nitro group is selected.
