IMMH001, which is a prodrug for sphingosine-1-phosphate receptor 1 (S1P1) agonist, is converted to the active form, its monophosphate ester (S)-IMMH001-P, by sphingosine kinase 1 (SphK1) and sphingosine kinase 2 (SphK2) in vivo. In this study, we designed head-piece-modified analogues of IMMH001 based on structural information and prepared them with an efficient modular synthetic strategy. The analogues
IMMH001是鞘氨醇1-磷酸受体1(S1P 1)激动剂的前药,通过鞘氨醇激酶1(SphK1)和鞘氨醇激酶2(SphK1)转化为活性形式,即单磷酸酯(S)-IMMH001-P。 SphK2)体内。在这项研究中,我们根据结构信息设计了IMMH001的头部修饰类似物,并采用有效的模块化合成策略对其进行了制备。该类似物在人血中显示出比母体化合物更高的磷酸化率。这些结果表明,亲- [R在的IMMH001防止亲头片基的部分羟甲基小号羟甲从由激酶和ATP磷酸化被。这些类似物可能具有更好的治疗潜力。
