To explore non‐aniline aromatic substitution on the pyrimidine C4 position, novel 4‐(N,N′‐di‐n‐propyl‐3,4‐dicarboxamido‐1H‐pyrrole)pyrimidines are designed and synthesized as anaplastic lymphoma kinase inhibitors for non‐small cell lung cancer treatment. To overcome the unexpected cleavage between the C‐N linkage of pyrrole nitrogen and C4‐pyrimidine during hydrolysis and inaccessibility of the desired diamide formation through coupling agent‐mediated conditions, the 4‐(N,N′‐di‐n‐propyl‐3,4‐dicarboxamido‐1H‐pyrrole)pyrimidine was assembled through direct nucleophilic substitution under microwave irradiation. Thus prepared 4‐(N,N′‐di‐n‐propyl‐3,4‐dicarboxamido‐1H‐pyrrole)pyrimidines were measured both ALK binding and H3122 cell proliferation assay. Their weak ALK activities are explained with molecular modeling study.
为了探索嘧啶 C4 位上的非苯胺芳香取代,设计并合成了新型 4-(N,N′-二正丙基-3,4-二羧酰胺基-1H-吡咯)嘧啶,作为治疗非小细胞肺癌的无性淋巴瘤激酶抑制剂。为了克服在水解过程中吡咯氮和 C4-嘧啶的 C-N 连接意外断裂以及在偶联剂介导的条件下无法形成所需的二酰胺的问题,在微波辐照下通过直接亲核取代组装了 4-(N,N′-二正丙基-3,4-二羧酰胺基-1H-吡咯)嘧啶。对制备的 4-(N,N′-二正丙基-3,4-二羧氨基-1H-吡咯)嘧啶进行了 ALK 结合和 H3122 细胞增殖试验。分子建模研究解释了它们较弱的 ALK 活性。
