Novel gemini (tail-head-spacer-head-tail) bis-quaternary ammonium compounds (bis-QACs) with a biphenyl spacer between two pyridinium heads were synthesized and compared with commonly used antiseptics such as benzalkonium chloride (BAC) and chlorhexidine digluconate (CHG). The series of compounds showed high inhibitory activity against five bacterial strains and two fungi. The compounds, which contain
合成了在两个吡啶鎓头之间具有联苯间隔物的新型双季铵化合物 (bis-QACs),并与常用的防腐剂如苯扎氯铵 (BAC) 和二葡萄糖酸氯己定进行了比较。 CHG)。该系列化合物对五种细菌菌株和两种真菌显示出高抑制活性。包含 CH-CH 脂肪族尾部的化合物在该系列中最好。反离子变化一般不会影响 MIC。还研究了对人胚胎肾细胞和溶血的细胞毒性。对于双 QAC,其细胞毒性作用低于 3,3'-[1,4-亚苯基双(氧基)]双(1-十二烷基吡啶鎓)二溴化物 (3PHBO-12),即它们最接近的结构类似物,以及对于 BAC。
