compounds 20a, b, and the N6-dimethyl-9-(piperidin-3′-yl)adenine compounds 21a, b, have been prepared as analogs of the naturally occurring aminoacyl nucleoside antibiotic puromycin. The diastereomers were separated using high-pressure liquid chromatography, and the absolute configuration of the more mobile diastereomer 20a was assigned as (3′S,5′R) by 1H and 13C nuclear magnetic resonance analysis
非对映异构 1-(哌啶-3'-基) 尿嘧啶化合物 20a、b 和 N6-二甲基-9-(哌啶-3'-基) 腺嘌呤化合物 21a、b,已制备为天然存在的氨酰基的类似物核苷类抗生素嘌呤霉素。使用高压液相色谱分离非对映异构体,并且通过 1H 和 13C 核磁共振分析和分子建模将更具流动性的非对映异构体 20a 的绝对构型指定为 (3'S,5'R)。因此,流动性较小的非对映异构体20b具有(3'R,5'S)构型。21a 和 21b 的构型与 20a 和 20b 类比。这些嘌呤霉素类似物已在体外测试了抗 HIV 和抗肿瘤活性。
