  摘要：

  干扰素基因刺激物 (STING) 是一种关键的衔接蛋白，在触发对感染的固有免疫反应中起着关键作用。STING 相关干扰素的产生参与抗炎、抗感染和抗肿瘤免疫。在此，对作为 STING 激动剂的一系列氨基苯并咪唑类似物的效力和类药特性进行了分析。通过基于单氨基苯并咪唑 (ABZI) 的结构修饰和优化，获得了具有纳摩尔 STING 激动活性的类似物。其中，化合物D59和D61显着增加了IFN -β和促炎细胞因子CXCL10的转录，以及显着诱导 THP1 细胞中 STING 下游蛋白的磷酸化。此外，化合物D61表现出良好的药代动力学特性和代谢稳定性。在 CT-26 同源小鼠荷瘤模型中，D61通过瘤内、静脉内、腹膜内和口服途径给药时，可有效抑制肿瘤生长并具有良好的耐受性。这项关于口服生物可利用的氨基苯并咪唑类似物的研究扩展了用于 STING 介导的免疫疗法的激动剂化学结构的多样性。
