A series of new 3-aroylpyrido[1,2-a]pyrimidines were synthesized from aryl methyl ketones in a simple two-step procedure and evaluated as nitric oxide synthases (NOS) inhibitors. In order to perform a structure–activity relationship study, different aroyl groups were introduced in 3-position and methyl groups were introduced at different positions of the pyrimidine heterocycle.

以简单的两步程序由芳基甲基酮合成了一系列新的3-芳基吡啶并[1,2- a ]嘧啶,并被评估为一氧化氮合酶(NOS)抑制剂。为了进行结构-活性关系研究,在3位引入了不同的芳酰基,在嘧啶杂环的不同位置引入了甲基。具有联苯甲酰基,苄氧基苯甲酰基或萘甲酰基的化合物表现出最高的抑制作用,通过在吡啶基[1,2- a]的8位引入甲基进一步增强了抑制作用。]嘧啶部分。一些化合物对纯化的诱导型NOS(iNOS)具有选择性显示出有希望的抑制作用,并且对刺激的RAW 264.7细胞中表达的iNOS也具有活性。
