A new class of β-aryloxyquinolines 3a–i and their pyrano[3,2-c]chromene derivatives 6a–r incorporating a validated molecular target has been synthesized via a nucleophilic displacement and a one-pot multicomponent reaction respectively. In vitro antimicrobial activity of the synthesized compounds were investigated against a representative panel of pathogenic strains specifically Bacillus subtilis,
分别通过亲核置换和一锅多组分反应合成了新型的β-芳氧基喹啉3a - i及其吡喃并[3,2- c ]色烯衍生物6a - r,其中包含已验证的分子靶标。研究了合成化合物对代表性的致病菌株的体外抗菌活性,这些致病菌株特别是枯草芽孢杆菌,破伤风梭菌,肺炎链球菌,大肠杆菌,伤寒沙门氏菌,霍乱弧菌,烟曲霉和白色念珠菌。化合物3c,3e,3g,6f,6l和6q显示出优异的抗菌活性,而化合物6p显示出比一线标准药物更强的抗真菌活性。评估了针对结核分枝杆菌H37Rv的体外抗结核活性,化合物6f成为具有更好抗结核活性的有希望的抗微生物成员。该化合物的大多数似乎是更好的抗菌剂,但抗结核药效果较差。
