Twenty eight new aryloxybenzene analogues were synthesized and their in vitro binding potencies toward S1PR2 were determined using a [32P]S1P competitive binding assay. Out of these new analogues, three compounds, 28c (IC50 = 29.9 ± 3.9 nM), 28e (IC50 = 14.6 ± 1.5 nM), and 28g (IC50 = 38.5 ± 6.3 nM) exhibited high binding potency toward S1PR2 and high selectivity over the other four receptor subtypes
合成了 28 种新的芳氧基苯类似物,并使用 [32P]S1P 竞争性结合测定法确定了它们对 S1PR2 的体外结合效力。在这些新的类似物中,三种化合物 28c (IC50 = 29.9 ± 3.9 nM)、28e (IC50 = 14.6 ± 1.5 nM) 和 28g (IC50 = 38.5 ± 6.3 nM) 表现出对 S1PR2 的高结合效力和对 S1PR2 的高选择性其他四种受体亚型(S1PR1、3、4 和 5;IC50 > 1000 nM)。三种强效化合物 28c、28e 和 28g 中的每一种都含有一个氟原子,可以开发用于 S1PR2 成像的 F-18 标记的 PET 放射性示踪剂。
