Cenerimod (ACT-334441) 是一种有效,选择性和具有口服活性的S1P1受体调节剂,EC50值为 1 nM。Cenerimod 对 hS1P1 的选择性比 hS1P2,hS1P3,hS1P4 和 hS1P5 受体亚型 (EC50s=>10000,228,2134 和 36 nM) 高出 16 倍以上。Cenerimod 可减轻鼠类实验性自身免疫性脑脊髓炎 (EAE)和鼠类硬皮病。
生物活性 | Cenerimod (ACT-334441) is a potent, selective and orally activeS1P1 receptormodulator, with anEC50of 1 nM. Cenerimod shows more than 36‐fold selctivity for hS1P1 over hS1P2, hS1P3, hS1P4, and hS1P5 receptor subtypes (EC50s=>10000, 228, 2134, and 36 nM, respectively). Cenerimod can attenuate murine experimental autoimmune encephalomyelitis (EAE) and murine sclerodermatous[1][2]. |
IC50& Target | S1PR1 1 nM (EC50) | S1PR5 36 nM (EC50) | S1PR5 228 nM (EC50) | S1PR4 2134 nM (EC50) |

体外研究 (In Vitro) | Cenerimod is a highly potent S1P1 receptor agonists in (35S)-GTPγS assays using HUVEC cell membrane preparations, with an EC50of 2 nM[1]. Cenerimod activates G protein and increases Ca2+signaling in CHO cells, with EC50s of 1 nM and 124 nM, respectively[1]. Cenerimod (5 μM; 24 h) inhibits collagen production in fibroblasts[2].

体内研究 (In Vivo) | Cenerimod (0.1-10 mg/kg; a single p.o.) reversibly reduces the number of circulating lymphocytes in a dose‐dependent manner in rats[1]. Cenerimod (6 mg/kg/day for 30 days; p.o.) attenuates disease in a mouse experimental autoimmune encephalitis (EAE) model[1]. Cenerimod (10 mg/kg/day for 42 days; p.o.) attenuates skin and lung fibrosis in Scl-cGVHD mice[2].
Animal Model: | Male Wistar rats weighing 294-510 g[1] | Dosage: | 0.1, 0.3, 1, 3 and 10 mg/kg | Administration: | A single p.o. | Result: | Effectively and reversibly reduced the blood lymphocyte counts, with a plateau reached after a single oral dose of 1 mg/kg. |
