Spingosine-1-phosphate receptor 1 (S1P1) has been actively pursued as an important therapeutic target in immune regulation. A series of 2-substituted 2-aminopropane-1,3-diols were designed and synthesized as selective S1P1 agonists. Most of the compounds with a biphenyl ether scaffold showed moderate to excellent S1P1/S1P3 selectivity. Compound 40c is identified as a potent S1P1 agonist with 350-fold S1P1/S1P3
Spingosine-1-磷酸受体1(S1P 1)已被积极追求为免疫调节中的重要治疗靶标。设计并合成了一系列2-取代的2-氨基丙烷-1,3-二醇作为选择性的S1P 1激动剂。大多数具有联苯醚支架的化合物显示出中等至出色的S1P 1 / S1P 3选择性。化合物40c被鉴定为具有350倍S1P 1 / S1P 3选择性的有效S1P 1激动剂。39c,40c的酒精形式在体内具有良好的淋巴细胞减少活性但对心率的影响微弱。为了更详细地研究2-取代的2-氨基丙烷-1,3-二醇的比吸收比,建立了COMFA(q 2 = 0.547 ,r 2 = 0.986)和COMSIA(q 2 = 0.544,r 2 = 0.943)模型。关于分子对接比对的研究,在预测激动剂的活性方面具有很高的可靠性。3D-QSAR模型将有助于设计新颖,有效和选择性的S1P 1激动剂。
