In the unsubstituted guanidines that exhibited low toxicity, optimum activity resulted when the aryl group was a 2-methylphenyl ring (11). Modifications to the guanidine group did not increase antihypertensive activity, but, in the 2-methylphenyl series, the N-n-butyl- and N-(2-methoxyethyl)guanidines (63 and 78) and the related iminoimidazolidine 93 were of comparable activity to that of the unsubstituted
发现一些2-芳基-5-胍基-(或N-取代的胍基)-1,3,4-噻二唑和密切相关的类似物可降低肾上腺皮质激素(DOCA)高血压的血压。在具有低毒性的未取代胍中,当芳基为2-甲基苯基环时,可获得最佳活性(11)。修饰胍基并没有增加抗高血压活性,但在2-甲基苯基系列中,Nn-丁基和N-(2-甲氧基乙基)胍(63和78)以及相关的亚氨基咪唑烷93具有与之相当的活性。与取代的胍衍生物相比,亚氨基咪唑烷93显示出更长的作用持续时间。对脱髓鞘的大鼠制剂的初步研究表明,这些噻二唑衍生物(11,63,
