5-Benzy-2-pyridine carboxylic acids, in which the benzyl group is optionally substituted by one or two like or different alkyl, halo, alkoxy, nitro, amino, acetamido, hydroxy or acetoxy groups, and the corresponding amides and esters, possess dopamine .beta.-hydroxylase inhibitory properties and are useful as blood pressure lowering agents. The compounds, of which 5-(4-chlorobenzyl)-2-pyridine carboxylic acid, 5-(4-hydroxybenzyl)-2-pyridine carboxylic acid and 5-benzyl-2-pyridine carboxylic acid are typical examples, can be prepared by a number of chemical methods.
5-苯基-2-吡啶羧酸,其中苯甲基可以选择性地被一个或两个相同或不同的烷基,卤素,烷氧基,硝基,氨基,乙酰胺基,羟基或乙酰氧基基团取代,相应的酰胺和酯具有多巴胺β-羟化酶抑制作用,可用作降低血压的药物。这些化合物,其中5-(4-氯苯甲基)-2-吡啶羧酸,5-(4-羟基苯甲基)-2-吡啶羧酸和5-苯甲基-2-吡啶羧酸是典型的例子,可以通过多种化学方法制备。
