合成了erythro-1,6-Dihydro-6-(hydroxymethyl)-9-(2-hydroxy-3-nonyl)purine(4)作为潜在的腺苷脱氨酶抑制剂,它在一个分子中结合了两个结构部分,每个结构部分它对酶的不同区域,催化区域和对赤型9-(2-羟基-3-壬基)腺嘌呤(1)具有特异性的辅助结合区域具有高度亲和力。4的效力(Ki = 1.2 x 10(-5)M)约为赤型9-(2-羟基-3-壬基)嘌呤(2; Ki = 6.8 x 10(-7)M的效力的十七分之一),其中仅包含一个高亲和力部分。这两个部分的相互干扰而不是增强的作用可能表明缺乏同时结合,从而提供了对酶的两个结合区域的相对几何结构的了解。

6-Dihydro-6-(hydroxymethyl)-9-(2-hydroxy-3-nonyl)purine (4) was synthesized as a potential adenosinedeaminaseinhibitor, which combines in a single molecule two structural moieties, each of which possesses high affinity to a different region of the enzyme, the catalytic region and an auxiliary binding region which is specific for erythro-9-(2-hydroxy-3-nonyl)adenine (1). The potency of 4 (Ki = 1.2
