was found in both the 2(1H)- and 4(3H)-pyrimidinone series and was most prominent in analogues containing either an electron-withdrawing or -donating substituent in the para position of the phenoxy ring. Significant antiulcer activity was observed only in the 2(1H)-pyrimidinone series among three closely related analogues. One of these, 5-(m-methylphenoxy)-2(1H)-pyrimidinone (3), exhibited more potent
在制备作为潜在的环状核苷酸调节剂的铅的后续步骤中,制备了一系列5-苯氧基-2(1H)-嘧啶酮,5-苯氧基-4(3H)-嘧啶酮和相关化合物。评价化合物在组胺攻击的豚鼠中的支气管扩张剂活性,以及在冷约束,应激大鼠溃疡模型中的抗增白剂活性。在2(1H)-和4(3H)-嘧啶酮系列中发现与茶碱相当或更高的支气管扩张剂活性,在对位上含有吸电子或供电子取代基的类似物中最显着苯氧基环。在三个密切相关的类似物中,仅在2(1H)-嘧啶酮系列中观察到了显着的抗溃疡活性。5-(间甲基苯氧基)-2(1H)-嘧啶酮(3)中的一种,
