  We have previously identified the 7,8,9,10-tetrahydro-7,10-ethano-1,2,4-triazolo[3,4-a]phthalazine (1) as a potent partial agonist for the alpha(3) receptor subtype with 5-fold selectivity in binding affinity over alpha(1). This paper describes a detailed investigation of the substituents on this core structure at both the 3- and 6-positions. Despite evaluating a wide range of groups, the maximum selectivity

  我们之前已经确定了7,8,9,10-四氢-7,10-乙醇-1,2,4-三唑并[3,4-a]酞嗪（1）是α（3）的有效部分激动剂。受体亚型，对α（1）的结合亲和力具有5倍的选择性。本文描述了在此核心结构的3位和6位上的取代基的详细研究。尽管评估了广泛的组，但相对于alpha（1）亚型，对alpha（3）亚型的亲和力可达到的最大选择性是12倍（对于57）。尽管大多数类似物在功效上均未显示选择性，但一些类似物确实在α（1）处表现出部分激动作用，而在α（3）处表现出拮抗作用（例如25和75）。但是，测试了两个类似物（93和96），它们都在6位上有三唑取代基，显示出对alpha（3）亚型的疗效明显高于alpha（1）亚型。这是该系列中可以在所需方向上实现选择性的第一个迹象。
