drug resistance and inadequate efficacy. In this case, the exploration of inhibitors targeting both JAK and SYK has emerged as a promising therapeutic strategy. In this study, a series of novel pyrrolo[2,3-]pyrimidine derivatives were designed and synthesized to selectively inhibit both JAK3 and SYK. The lead compound, , demonstrated an IC value of 2.14 μM against JAK3 and 7.10 μM against SYK, while exhibiting
Janus 激酶 (JAK) 和脾
酪氨酸激酶 (SYK) 是参与免疫调节的两种重要
酪氨酸激酶,代表了免疫性疾病的已启动治疗靶点。然而,针对单一激酶的单一疗法遇到了耐药性和疗效不足的挑战。在这种情况下,针对 JAK 和 SYK 的
抑制剂的探索已成为一种有前景的治疗策略。在本研究中,设计并合成了一系列新型
吡咯并[2,3-]
嘧啶衍
生物来选择性抑制JAK3和SYK。先导化合物,对 JAK3 的 IC 值为 2.14 μM,对 SYK 的 IC 值为 7.10 μM,而对 GSK3β 的活性可忽略不计(IC > 50 μM),为选择性 JAK/SYK 双
抑制剂的开发提供了一个命中支架。
