  drugs. Accordingly, in this research, we report the design, synthesis and biological evaluation of a series of novel phenylalanine derivatives as HIV-1 CA protein inhibitors using the Cu(I)-catalyzed azide and alkyne 1,3-dipolar cycloaddition (CuAAC) reaction. Among this series of inhibitors, compound II-10c displayed a remarkable anti-HIV activity (EC50 = 2.13 μM, CC50 > 35.49 μM). Furthermore, surface

  HIV-1 衣壳 (CA) 蛋白在病毒生命周期的早期和晚期都发挥着至关重要的作用，这引起了研究人员的兴趣，将其作为开发抗 HIV 药物的目标。因此，在这项研究中，我们报告了一系列新型苯丙氨酸衍生物作为 HIV-1 CA 蛋白抑制剂的设计、合成和生物学评估，这些衍生物使用 Cu(I) 催化的叠氮化物和炔烃 1,3-偶极环加成 (CuAAC) 反应. 在这一系列抑制剂中，化合物 II-10c 表现出显着的抗 HIV 活性（EC50 = 2.13 μM，CC50 > 35.49 μM）。此外，表面等离子共振 (SPR) 结合试验表明化合物 II-10c 和 PF-74（先导化合物）与 HIV-1 CA 单体具有相似的亲和力。进一步研究表明，代表性化合物的弱渗透性和水溶性可能是限制其细胞活性的重要因素。根据这些化合物的活性及其已知结构推断出初步的构效关系 (SAR)。通过分子动力学模拟 (MD)
