Delgocitinib (Corectim(Delgocitinib)) 是一种有效的、有特异性的 JAK 抑制剂,对 JAK1, JAK2, JAK3 和 Tyk2 具有抑制作用,其 IC50 值分别为 2.8,2.6,13 和 58 nM。Delgocitinib 通过JAK-依赖性细胞因子参与多种炎症和自身免疫性疾病,可广泛用于治疗各种炎症性疾病,是全球首款治疗特应性皮炎的JAK 局部外用化合物
Delgocitinib (JTE-052) is a specific JAK inhibitor with IC 50 s of 2.8, 2.6, 13 and 58 nM for JAK1 , JAK2 , JAK3 and Tyk2 , respectively
In Vitro
In the enzymatic assays, Delgocitinib potently inhibits all of the JAK subtypes with IC 50 values of 2.8±0.6, 2.6±0.2, 13±0 and 58±9 nM for JAK1, JAK2, JAK3 and Tyk2, respectively. Lineweaver-Burk plots show that the inhibition mode of Delgocitinib toward all JAKs is competitive with ATP with K i values of 2.1±0.3, 1.7±0.0, 5.5±0.3 and 14±1 nM for JAK1, JAK2, JAK3 and Tyk2, respectively. In these cell-based cytokine signaling assays, Delgocitinib inhibits the phosphorylation of Stat proteins induced by IL-2, IL-6, IL-23, GM-CSF, and IFN-α with IC 50 values of 40±9, 33±14, 84±11, 304±22 and 18±3 nM, respectively. Delgocitinib also inhibits IL-2-induced proliferation of T cells in a concentration-dependent manner (IC 50 =8.9±3.6 nM), and its potency is similar to that of CP-690550 (IC 50 =16 nM). MCE has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
Delgocitinib decreases the IFN-γ production, but the potency of the 1-h prior administration is higher than that of the 6-h prior administration (ED 50 =0.24 versus 1.3 mg/kg). In the administration from day 1, Delgocitinib prevents the development of hind paw swelling and histological changes of inflammatory cell infiltration and synovial cell hyperplasia. Delgocitinib inhibits radiographic and histological changes of bone destruction and cartilage destruction. In the administration from day 15, Delgocitinib decreases the paw swelling in a dose-dependent manner. In addition, Delgocitinib ameliorates the inflammatory cell infiltration, synovial cell hyperplasia, and cartilage/bone destructions in the histological and radiographic examinations at the end of the study . MCE has not independently confirmed the accuracy of these methods. They are for reference only.
