Tolebrutinib 是一种选择性、有效的、具有口服活性、可透过血脑屏障的布鲁顿氏酪氨酸激酶抑制剂，能够作用于 Ramos B 细胞 (IC50:0.4 nM)、HMC 小胶质细胞 (IC50:0.7 nM)。它对中枢神经系统免疫具有功效。它可用于多发性硬化症的研究。

Tolebrutinib is a potent, selective, orally active and brain-penetrant Bruton tyrosine kinase (BTK) inhibitor(IC50s of 0.4 and 0.7 nM in Ramos B cells and in HMC microglia cells, respectively). It exhibits efficacy in central nervous system immunity. Tolebrutinib can be used for the research of multiple sclerosis (MS).

PRN2246 inhibits microglial FcγR activation through durable occupancy of BTK, with an IC50 of 157 nM.?PRN2246 blocks the BCR-mediated activation (IC50=10 nM) and Fc receptor activation (IC50=166 and 9.6 nM for FcεR and FcγR, repectively) of immune cells[1].

PRN2246 produces dose-dependent protection from in myelin oligodendrocyte glycoprotein (MOG)-induced experimental autoimmune encephalomyelitis (EAE) model[1]
