生物活性

Amiselimod (MT-1303) hydrochloride is converted to its active metabolite Amiselimod phosphate by sphingosine kinases in vivo. Amiselimod hydrochloride is an orally active and high selectivity sphingosine 1-phosphate receptor-1 (S1P1) agonist, designed to reduce the bradycardia effects associated with fingolimod and other S1P receptor modulators. Amiselimod hydrochloride inhibits chronic colitis via inhibiting infiltration of colitogenic Th1 and Th17 cells into the colon. Amiselimod hydrochloride inhibits lupus nephritis by reducing the infiltration of autoreactive T cells into the kidneys. Amiselimod hydrochloride is promising for research of autoimmune diseases[1][2][3][4].

体外研究
(In Vitro)

Amiselimod hydrochloride (100 nM, 12 h) 在 HEK293 细胞或原代 HCMs (人类心肌细胞) 中转化为Amiselimod-P 的速度比 Fingolimod (HY-11063) 转化为 fingolimod-P 的速度慢[1]。 Amiselimod-P (0.001-1000 nM) 在人 S1P1 受体表达细胞中表现出 S1P1 受体激动剂活性, EC50 为 75 pM, 其活性高于在 S1P4 和 S1P5 受体上的活性,但在 S1P2 或 S1P3 受体上没有明显的激动剂活性[1]
Amiselimod-P (0.001-1000 nM) 在人类心房肌细胞中以浓度依赖的方式增加 G 蛋白激活的内向整流钾通道(GIRK) 电流幅度,其 EC50 值为 41.6 nM[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.
