  Synthesis of substituted 5-bromomethyl-4-nitroimidazoles and use for the preparation of the hypoxia-selective multikinase inhibitor SN29966

  摘要：

  5-Bromomethyl-4-nitroimidazoles have utility as bioreductive trigger precursors for the preparation of hypoxia-selective prodrugs. Here we describe an efficient two-step synthesis of 5-(bromomethyl)-1-methyl-4-nitro-1H-imidazole, a preferred precursor, employing an N-bromosuccinimide mediated radical bromination. Use of this precursor to prepare SN29966, a promising hypoxia-selective irreversible pan-ErbB inhibitor is reported along with the preparation of four other prodrug candidates. 5-Bromomethyl-4-nitroimidazole analogues bearing electron-donating and electron-withdrawing substituents at the N-1 and C-2 positions are also described.

  The invention provides novel prodrug compounds comprising a kinase inhibitor and a reductively-activated fragmenting aromatic nitroheterocycle or aromatic nitrocarbocycle trigger, where the compound carries a positive charge. In preferred embodiments, the compounds are of Formula I: where: X is any negatively charged counterion; R 1 is a group of the formula —(CH 2 ) n Tr, where Tr is an aromatic nitroheterocycle or aromatic nitrocarbocycle and —(CH 2 ) n Tr acts as a reductively-activated fragmenting trigger; and n is an integer from 0 to 6; R 2 , R 3 and R 4 may each independently be selected from aliphatic or aromatic groups of a tertiary amine kinase inhibitor (R 2 )(R 3 )(R 4 )N, or two of R 2 , R 3 , and R 4 may form an aliphatic or aromatic heterocyclic amine ring of a kinase inhibitor, or one of R 2 , R 3 and R 4 may be absent and two of R 2 , R 3 and R 4 form an aromatic heterocyclic amine ring of a kinase inhibitor. The compounds of the invention are useful in treating proliferative diseases such as cancer.
