(1H-Pyrazol-1-yl)-, (1H-imidazol-1-yl)-, and (1H-1, 2, 4-triazol-1-yl)phrimidines were prepared and evaluated for cytoprotective antiulcer activity. Among them, 4-methoxy-6-methyl-2-(1H-pyrazol-1-yl)pyrimidine (18) showed potent inhibition of the HCl-ethanol-induced and water-immersion stress-induced ulcers in rats, as well as low acute toxicity.
(1H-吡唑-1-基)、(1H-咪唑-1-基)和(1H-1, 2, 4-三唑-1-基)嘧啶的衍生物被合成并评估其细胞保护的抗溃疡活性。其中,4-甲氧基-6-甲基-2-(1H-吡唑-1-基)嘧啶(18)显示出对盐酸-乙醇诱导和水浸应激诱导的溃疡具有强效的抑制作用,并且急性毒性低。
