药效药理
作用机制
芬戈莫德在体内代谢为磷酸化代谢物,即活性代谢物。淋巴结作为S1P1受体的功能性拮抗剂,通过与 1-磷酸鞘氨醇(S1P)受体1(S1P1受体)结合并诱导其内化和降解。抑制淋巴细胞从次级淋巴组织中的输出,例如。自身反应性T细胞,包括髓鞘抗原特异性Th17细胞,也通过类似机制抑制淋巴结迁移,从而抑制浸润到中枢神经系统组织。
另一方面,芬戈莫德对效应记忆T细胞几乎没有影响,因为在外来病原体感染中起重要作用的效应记忆T细胞没有通过次级淋巴组织循环的能力。
芬戈莫德还被证明可以迁移到人类和动物的中枢神经系统(CNS)并抑制星形胶质细胞增生、脱髓鞘和神经元损伤。
实验性自身免疫性脑脊髓炎(EAE)
在多发性硬化症动物模型小鼠的复发缓解型EAE中,口服芬戈莫德治疗时,对神经系统症状的复发显示出抑制作用。
