starting point for the development of IDO1 inhibitors. With the aim of discovering more potent ligands, a virtual library of imidazoles synthesizable via the van Leusen multicomponent reaction was created and filtered to afford a set of 4,5- and 1,5-disubstituted imidazoles as virtual lead candidates. The compounds were selected according to their docking score and to their synthetic feasibility, synthesized
吲哚胺2,3-二加氧酶参与病理性免疫逃逸,最近已成为抗癌治疗的有吸引力的靶标。4-苯基咪唑(4-PI)为IDO1抑制剂的开发提供了一个有希望的起点。为了发现更有效的配体,可通过以下方法合成一个虚拟的咪唑文库产生van Leusen多组分反应并过滤,得到一组4,5-和1,5-二取代的咪唑作为潜在的潜在候选铅。根据化合物的对接分数和合成可行性选择化合物,进行合成和生物学评估。与4-PI相比,这种实验方法产生的IDO1抑制剂具有增强的效力。活性最高的化合物在酶和细胞分析中均显示出较低的微摩尔效价,而无可检测的细胞毒性。观察到基于静电和空间配体-蛋白质相互作用的3D定量结构-活性关系。
