Ivarmacitinib (SHR0302) 是一种有效的具有口服活性的JAK抑制剂,尤其是JAK1的抑制剂。Ivarmacitinib 对JAK1的选择性是JAK2的 10 倍以上,是JAK3的 77 倍,是Tyk2的 420 倍。Ivarmacitinib 抑制JAK1-STAT3磷酸化并诱导肝星状细胞凋亡 (apoptosis)。Ivarmacitinib 具有抗增殖和抗炎作用。
生物活性 | Ivarmacitinib (SHR0302) is a potent and orally active all members of theJAKfamilyinhibitor, particularlyJAK1. The selectivity of Ivarmacitinib forJAK1is >10-fold forJAK2, 77-fold forJAK3, 420-fold forTyk2. Ivarmacitinib inhibitsJAK1-STAT3phosphorylation and induces theapoptosisof hepatic stellate cells. Ivarmacitinib has anti-proliferative and anti-inflammatory effects[1][2]. |

体外研究 (In Vitro) | Ivarmacitinib (SHR0302; 1 nM-10 μM; 48 hours; HSCs) treatment displays an inhibitory effect on the proliferation of HSCs in a concentration-dependent manner[2]. Ivarmacitinib (1 nM-10 μM) exerts an inhibitory effect on the activation, proliferation and migration of HSCs[2]. Ivarmacitinib (1 nM-10 μM; 48 hours; HSCs) treatment induces the apoptosis of HSCs[2]. Ivarmacitinib (1 nM-10 μM; 48 hours; HSCs) treatment significantly increases the activation of caspase-3 and Bax in HSCs, and decreases the expression of Bcl-2. SHR0302 also inhibits the activation of Akt signaling pathway[2].

体内研究 (In Vivo) | Ivarmacitinib (SHR0302; 0.3-3.0 mg/kg; intragastric administration; twice a day; for 14 days; male Sprague-Dawley (SD) rats) treatment suppresses the severity of AA rats by attenuating the arthritis index, arthritis global assessment and paw swelling degree, and alleviated histopathology of spleen and joint of AA rats[1]. Ivarmacitinib can inhibit the proliferation of T, B and fibroblast-like synoviocytes (FLS), and down-regulates cytokines TNF-α, IL-1β, IL-17 and antibody IgG1, IgG2a levels, and suppresses the proportion of Th17 and total B, and inhibits JAK1-STAT3 phosphorylation[1].
Animal Model: | Male Sprague-Dawley (SD) rats (150-180 g) injected with complete Freund’s adjuvant (CFA)[1] | Dosage: | 0.3 mg/kg,1.0 mg/kg, 3.0 mg/kg | Administration: | Intragastric administration; twice a day; for 14 days | Result: | Suppressed the severity of adjuvant-induced arthritis (AA) rats by attenuating the arthritis index, arthritis global assessment and paw swelling degree, and alleviated histopathology of spleen and joint of AA rats. |
