  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 nitroheterocyde 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.

  本发明提供了新型的前药化合物，包括一种激酶抑制剂和一种还原活化的分裂芳香族硝基杂环或芳香族硝基碳杂环触发物，其中该化合物带有正电荷。在优选实施例中，该化合物的化学式为I：其中：X是任何带负电的反离子；R1是公式—（CH2）nTr的基团，其中Tr是一种芳香族硝基杂环或芳香族硝基碳杂环，而—（ ）nTr作为还原活化的分裂触发器；n是从0到6的整数；R2、R3和R4可以各自独立地选择来自三级胺激酶抑制剂（R2）（R3）（R4）N的脂肪族或芳香族基团，或者R2、R3和R4中的两个可以形成激酶抑制剂的脂肪族或芳香族杂环胺环，或者R2、R3和R4中的一个可以不存在，而R2、R3和R4中的两个可以形成激酶抑制剂的芳香族杂环胺环。本发明的化合物在治疗增殖性疾病如癌症方面是有用的。
