Novel pyrimidines were prepared by the condensation of chalcones of 4'-piperazine acetophenone with guanidine HCl. The structures of the synthesized compounds RP 1-5 were assigned on the basis of elemental analysis, IR, (1)H NMR and mass spectroscopy. These compounds were also screened for anti-histaminic activity. The recorded percentage of histamine inhibition showed a significant anti-histaminic activity when compared to the reference anti-histaminic drug mepiramine.
新型嘧啶类化合物是由 4'-哌嗪苯乙酮查耳酮与盐酸胍缩合而成。根据元素分析、IR、(1)H NMR 和质谱,确定了合成化合物 RP 1-5 的结构。这些化合物还进行了抗组胺活性筛选。与参考抗组胺药哌啶嗪相比,记录的组胺抑制百分率显示出显著的抗组胺活性。
