employed has been a solution-phase parallel synthesis based on the coupling of three thymine-derived acids [4-(thymin-1-yl)butyric acid (I), [4-(thymin-1-yl)-butyrylamino]acetic acid (II) and 6-(thymin-1-yl)hexanoic acid (III)] with different commercially available primary amines that carry cyano and/or phenyl groups. The couplings were performed in good yields (from 60% to 90%), with the exception of those
基于我们先前确定的线粒体胸苷激酶(TK-2)抑制剂的结构,合成了三组源自胸腺嘧啶的羧酰胺,并针对TK-2和相关酶进行了测试。所采用的方法是基于三种胸腺嘧啶衍生的酸[4-(胸苷-1-基)丁酸(I),[4-(胸苷-1-基)-丁酰氨基]偶合的溶液相平行合成。乙酸(Ⅱ)和6-(胸腺嘧啶-1-基)己酸(Ⅲ)]和带有氰基和/或苯基的可商购的不同伯胺。除掺入高度拥挤的三苯甲胺(e)的偶联剂外,偶联剂均以良好的收率(60%至90%)进行。从新合成的化合物中,N-三苯甲基-6-(胸腺嘧啶-1-基)己酰胺(IIIe)是最具活性的TK-2抑制剂(IC(50)= 19 +/- 2microM)。
