synthesized compounds were screened for their antimicrobial activities. In general, most compounds except 22 were Found (%) to be active against Mycobacterium smegmatis, Candida albicans and/or Saccharomyces cerevisiae. Furthermore, 9a and b, which are Mannich bases incorporating morpholine or piperazine nucleus, exhibited excellent antimicrobial activity on test microorganisms. In addition, the hydrazide
所述carbothioamides合成(5,13,22)进行从3开始ħ -1,2,4-三唑-3-酮(2,17)由几个步骤,然后,这些carbothioamides转化为包含1三杂环化合物1,2,4-三唑,咪唑和1,3-噻唑(idinone)部分。化合物2与3,4-二氟硝基苯的反应得到2-(2-氟-4-硝基苯基)衍生物10。通过硝基的还原,将化合物10转化为亚芳基氨基衍生物(12a,b)。另一方面,酰肼的处理(20)是从17开始获得的,与几种芳族醛生成相应的芳基酰肼(21a – c)。化合物2与合适的杂环胺之间的曼尼希反应导致2的N-烷基化。筛选所有新合成的化合物的抗菌活性。通常,发现除22种化合物外,大多数化合物(%)对耻垢分枝杆菌,白色念珠菌和/或酿酒酵母具有活性。此外,9a和b,是结合了吗啉或哌嗪核的曼尼希碱,对测试微生物表现出出色的抗菌活性。此外,发现酰肼4(%)对Ec和Yp具有活性。
