with a 2-substituted phenyl ring had higher activity than their 3- or 4-substituted counterparts or those containing heteroaryl groups. The 2-methylphenyl and 2-ethylphenyl derivatives 7 and 18 were the most potent members of the series. Preliminary studies indicated that the hypotensive action of these compounds was due to a direct relaxant effect on vascular smooth muscle.
已经合成了一些2-芳基-5-肼基-1,3,4-噻二唑并筛选了其降压活性。通常,具有2-取代的苯环的化合物比其3-或4-取代的对应物或含有杂芳基的化合物具有更高的活性。2-甲基苯基和2-乙基苯基衍生物7和18是该系列中最有效的成员。初步研究表明,这些化合物的降压作用归因于对血管平滑肌的直接松弛作用。
