A series of cyano-substituted 2,4-diarylaminopyrimidines was designed and synthesized as potent non-covalent JAK3 inhibitors. Among the derivatives synthesized, 9o (IC50 = 22.86 nM), 9 k (IC50 = 21.58 nM), and 9j (IC50 = 20.66 nM) demonstrated inhibitory potencies against JAK3 similar to the known JAK3 inhibitor tofacitinib (IC50 = 20.10 nM). Moreover, 9o displayed potent anti-proliferative activities
设计并合成了一系列氰基取代的 2,4-二芳基氨基嘧啶作为有效的非共价 JAK3 抑制剂。在合成的衍生物中,9o (IC 50 = 22.86 nM)、9 k (IC 50 = 21.58 nM) 和9j (IC 50 = 20.66 nM) 对 JAK3 的抑制效力类似于已知的 JAK3 抑制剂托法替尼 (IC 50 = 20.10)毫)。此外,9o对 Raji 和 Ramos 细胞显示出有效的抗增殖活性,IC 50值分别为 0.9255 μM 和 1.405 μM。此外,9o在正常 HBE(人支气管上皮细胞,IC50 > 10 μM)和 L-02(人肝细胞,IC 50 = 3.104 μM)细胞。流式细胞术对作用方式的分析表明,9o在 G2/M 期有效地阻止了 Raji 细胞。综上所述,这些结果表明9o可能是作为 B 细胞淋巴瘤潜在治疗方法开发的有希望的候选者。
