Several α-hydroxyamides with (2,6-dialkoxyphenoxy)methyl substituents have been prepared and their activities as antagonists of the M3 muscarinic receptor in guinea pig ileum have been evaluated. N-1-[(Phenyl)methyl]piperidin-4-yl}-2-2-[(2,6-dimethoxyphenoxy)-methyl]phenyl}-2-hydroxypropanamide and N-(1-[6-amino-4-[(1-propylpiperidin-4-yl)methyl]pyridin-2-yl}methyl]piperidin-4-yl)-2-cyclopentyl-2-hydroxy-2-phenylacetamide were the most potent compounds prepared, the micromolar potency of the latter indicating that it may be worth further investigation.
已准备了几种具有(2,6-二烷氧基苯氧基)甲基取代基的α-羟基酰胺,并评估它们作为豚鼠回肠M3胆碱能受体拮抗剂的活性。N-1-[(苯基)甲基]哌啶-4-基}-2-2-[(2,6-二甲氧基苯氧基)甲基]苯基}-2-羟基丙酰胺和N-(1-[6-氨基-4-[(1-丙基哌啶-4-基)甲基]吡啶-2-基}甲基]哌啶-4-基)-2-环戊基-2-羟基-2-苯乙酰胺是制备的最有效化合物,后者的微摩尔效力表明它可能值得进一步研究。
