JAK3- in -11 (Compound 12) 是一种有效的、无细胞毒性、不可逆、具有口服活性的JAK3抑制剂，IC50值为1.7 nM，具有优良的选择性(高于其他 JAK3 亚型的588倍)，共价结合到 JAK3 的 ATP-binding pocket。 JAK3-IN-11 强烈抑制 JAK3 依赖的信号转导和T细胞增殖，是研究自身免疫性疾病的有效工具。
| 生物活性 | JAK3-IN-11 (Compound 12), a potent, noncytotoxic, irreversible, orally activeJAK3inhibitor withIC50value of 1.7 nM, has excellent selectivity (>588-fold compared to otherJAKisoforms), covalently bind to the ATP-binding pocket inJAK3. JAK3-IN-11 strongly inhibits JAK3-dependent signaling and T cell proliferation, is a promising tool for studyautoimmunediseases[1]. |
