Substituted pyridines were synthesized as potential angiotensin II (AII) receptor antagonists. Substitution at the position 2 in the pyridine resulted in potent activity, and the optimal alkyl length was four carbons. The potency further increased with the introduction of a hydroxymethyl group at the position 4. One of the compounds, 2-butyl-6-chloro-4-hydroxymethyl-5-methyl-3-[[2'-(1H-tetrazol-5-yl
取代的吡啶被合成为潜在的血管紧张素II(AII)受体拮抗剂。在吡啶的2位取代导致有效的活性,并且最佳的烷基长度为四个碳。随着在位置4处引入羟甲基的影响,效力进一步提高。化合物之一是2-丁基-6-氯-4-氯甲基-4-羟甲基-5-甲基-3-[[2'-(1H-四唑-5) -yl)联苯基-4-yl]甲基]吡啶9 h(KT3-579)是竞争性AII拮抗剂,pA2值为9.31,效力是Du Pont 753的约10倍。发现它是AT1特异性拮抗剂,IC50为3.09 nM。
