激酶抑制剂的前药形式及其在治疗中的用途
摘要：
本发明提供了新的前药化合物，其包含激酶抑制剂和还原性活化的可断裂的芳族硝基杂环或芳族硝基碳环触发剂，其中所述化合物携带正电荷。在优选的实施方案中，所述化合物为式I：其中，X是任何负电荷的平衡离子；R1是式-(CH2)nTr的基团，其中Tr是芳族硝基杂环或芳族硝基碳环，并且-(CH2)nTr作为还原性活化的可断裂触发剂起作用，n是0-6的整数；R2、R3和R4各自独立的选自叔胺激酶抑制剂(R2)(R3)(R4)N的脂肪族和芳族基团，或R2、R3和R4中的两者可形成激酶抑制剂的脂肪族或芳族杂环胺环，或R2、R3和R4中的一个可不存在，R2、R3和R4中的两个可形成激酶抑制剂的芳族杂环胺环。本发明的化合物可用于治疗增殖性疾病例如癌症。
摘要（英）：

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; R1 is a group of the formula -(CH2)nTr, where Tr is an aromatic nitroheterocycle or aromatic nitrocarbocycle and -(CH2)nTr acts as a reductively-activated fragmenting trigger; and n is an integer from 0 to 6; ; R2, R3 and R4 may each independently be selected from aliphatic or aromatic groups of a tertiary amine kinase inhibitor (R2)(R3)(R4)N, or two of R2, R3, and R4 may form an aliphatic or aromatic heterocyclic amine ring of a kinase inhibitor, or one of R2, R3 and R4 may be absent and two of R2, R3 and R4 form an aromatic heterocyclic amine ring of a kinase inhibitor. The compounds of the invention are useful in treating proliferative diseases such as cancer.
