derivatives and related compounds were synthesized and evaluated for histamine H2-receptor antagonist and gastric acid antisecretory activities. Among them, compounds I-17, I-48 and I-49 showed high activities in these tests. In addition, compound I-17 possessed potent inhibitory activities on each of the gastric ulcers induced by stress, ethanol and HCl-aspirin. On the other hand, compound I-48 demonstrated
合成了一系列的4-呋喃基-2-胍基噻唑衍生物和相关化合物,并评估了组胺H2-受体拮抗剂和胃酸的抗分泌活性。其中,化合物I-17,I-48和I-49在这些测试中显示出高活性。另外,化合物I-17对由压力,乙醇和HCl-阿司匹林诱导的每个胃溃疡具有有效的抑制活性。另一方面,化合物I-48显示出对幽门螺杆菌的抗菌活性,并且效力远强于临床使用的H2-拮抗剂。讨论了一些构效关系。
