描述了一系列的6-氯-4-氟烷基氨基-2-杂芳基-5-(取代)苯基嘧啶作为抗癌剂的合成和SAR。这一系列的2-杂芳基嘧啶是通过修饰我们先前报道的一系列抗肿瘤[1,2,4]三唑并[1,5- a ]嘧啶和2-氰基氨基嘧啶而开发的。对于2-杂芳基,当杂芳基在嘧啶基核的邻位具有氮原子时,可获得最佳活性。该2-杂芳基嘧啶系列中其余分子的结构-活性关系类似于[1,2,4]三唑[1,5- a ]的结构-活性关系]嘧啶系列。像三唑并嘧啶和2-氰基氨基嘧啶一样,2-杂芳基嘧啶保留克服由于Pgp引起的多药耐药性的能力。作用机理研究表明,先导化合物的行为与三唑并嘧啶和2-氰基氨基嘧啶相同。在体外和体内,该系列中的先导化合物比相应的三唑并嘧啶更有效。化合物21(PTI-868)在几种裸鼠异种移植模型中均显示出抑制肿瘤生长的作用,因此被选择进行临床前开发。
