proliferation and immune suppression. A series of novel quinazoline compounds with dual-target inhibition function was constructed using the skeleton growth method, and their structures were synthesized, characterized, and evaluated. Among them, the perfected compounds (L11, L20, L21) were selected for further study, which exhibited remarkable biological activity against different fungal strains (MIC50, 0
双靶点(CYP51/PD-L1)在真菌增殖和免疫抑制过程中发挥着重要作用。采用骨架生长法构建了一系列具有双靶点抑制功能的新型喹唑啉化合物,并对其结构进行了合成、表征和评价。其中,选择完善的化合物( L11、L20、L21 )进行进一步研究,其在体外对不同真菌菌株(MIC 50,0.25-2.0 μg/mL)表现出显着的生物活性。一方面,这些化合物抑制CYP51活性,诱导ROS聚集和线粒体损伤;这最终导致真菌裂解和死亡。另一方面,它们还通过阻断PD-L1和PD-1之间的相互作用,有效激活人体的免疫能力,减缓炎症反应,加速真菌感染的恢复过程。
