CS-0777-P 是 CS-0777 的磷酸化形式,是 S1P 受体-1 (S1P1) 的强效和选择性调节剂。CS-0777-P 对人 S1P1 比对 S1P3 的激动剂活性高大约 320 倍,EC50 为 1.1 nM。在药理研究中,CS-0777-P 作为 S1P1 和 S1P3 激动剂在体外表现出显著作用,导致外周血淋巴细胞计数降低并对大鼠实验性自身免疫性脑脊髓炎 (EAE) 产生抑制作用。大鼠药代动力学研究表明,口服给药后淋巴细胞计数迅速减少,这使得 CS-0777 有潜力用于多发性硬化症 (MS) 的研究。

生物活性

CS-0777-P, the phosphorylated form of CS-0777, acts as a potent and selective modulator of the S1P receptor-1 (S1P1). It exhibits approximately 320-fold higher agonist activity for human S1P1 compared to S1P3, with an EC50 of 1.1 nM. In pharmacological studies, CS-0777-P demonstrated significant effects in vitro as an S1P1 and S1P3 agonist, leading to lowered peripheral blood lymphocyte counts and suppressive effects on experimental autoimmune encephalomyelitis (EAE) in rats. Pharmacokinetic studies in rats revealed rapid lymphocyte count reductions following oral administration, making CS-0777 a promising candidate currently undergoing clinical trials for the treatment of multiple sclerosis (MS)[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
