Two distinct synthetic schemes were applied to access heteroatom-containing alpha-chain lactams or lactams terminated as aryl acids. The latter lactams were devised using a pharmacophore for EP(4) receptor activity. gamma-Lactams were characterized for their prostanoid EP receptor affinities and EP(4) activity and found to be selective for the EP(2) and EP(4) receptors or selective for the EP(4) subtype. Benzoic acid 17 displayed enhanced in vivo exposure relative to 3.
采用了两种不同的合成方案来制备含杂原子的α-链内酰胺或末端为芳基酸的内酰胺。后一种内酰胺是利用一种用于EP(4)受体活性的药效团设计的。γ-内酰胺通过其前列腺素EP受体亲和力和EP(4)活性进行表征,发现它们对EP(2)和EP(4)受体具有选择性,或者对EP(4)亚型具有选择性。相对于3,苯甲酸17在体内的暴露量有所增加。
