Mer 受体酪氨酸激酶的异常激活或过度表达与许多人类癌症的存活信号传导和化学抗性有关。因此,Mer 是一种很有前途的新型癌症治疗靶点。开发并验证了一种使用伪环置换策略的基于结构的药物设计方法,以发现新的吡啶嘧啶类似物家族作为有效的 Mer 抑制剂。通过 SAR 研究,基于对其他激酶的高选择性和良好的药代动力学特性,10 ( UNC2250 ) 被确定为进一步研究的先导化合物。当应用于活细胞时,10抑制内源性 Mer 的稳态磷酸化,IC 509.8 nM 并阻止配体刺激的嵌合 EGFR-Mer 蛋白激活。用10治疗还导致横纹肌样和非小细胞肺癌肿瘤细胞的集落形成潜力降低,从而显示出功能性抗肿瘤活性。结果为进一步研究该化合物在癌症患者中的治疗应用提供了依据。

The scope of an unexpected Mitsunobu cyclisation to prepare N-arylated Fsp3-enriched azacycles was investigated. In the current study, we have identified whether a pKa-dependent Mitsunobu cyclodehydration or a pKa-independent Mitsunobu intramolecular reaction was in operation. A Mitsunobu reaction, creating a leaving group, followed by intramolecular nucleophilic displacement was determined to be the
