Here we describe a new class of potent S1PR1 agonists wherein the exocyclic nitrogen was moved away from the pyridine ring (e.g. 11c). Further structural modifications led to the identification of novel alkylaminomethyl substituted phenyl and thienyl derivatives as potent S1PR1 agonists. These new alkylaminomethyl aryl compounds showed no phototoxic potential. Based on their in vivo efficacy and ability
在先前的通讯中,我们报告了烷基氨基吡啶衍生物(例如1)作为一类新型的有效,选择性和有效的S1P 1受体(S1PR 1)激动剂的发现。但是,更详细的分析表明,该化合物类别在体外具有光毒性。在这里,我们描述了一类新的强效S1PR 1激动剂,其中环外氮从吡啶环(例如11c)移开。进一步的结构修饰导致鉴定出新颖的烷基氨基甲基取代的苯基和噻吩基衍生物作为有效的S1PR 1激动剂。这些新的烷基氨基甲基芳基化合物无光毒性。根据他们的在体内功效和穿透大脑的能力方面,5-烷基-氨基甲基噻吩似乎是最有趣的一类。例如,向大鼠口服10 mg / kg的强效和选择性S1PR 1激动剂20e,在24小时内最大程度地降低了血淋巴细胞计数(LC),并且在24小时内其脑浓度达到了500 ng / g以上。
