Seventeen alkyl-substituted quaternary pyridinium compounds were synthesized by the condensation reaction of amino acids and primary amines with alkanals. The growth-inhibitorycapabilities of these pyridiniums were investigated against gram-negative and gram-positive bacteria (Escherichia coli and Streptococcus thermophilus), as well as against a mold (Neurospora crassa) and yeast (Candida utilis). Most of the pyridiniums appreciably inhibited the growth of the microorganisms tested. 1-Carboxymethyl-2-hexyl-3,5-dipentylpyridinium betaine and 1-(2-hydroxyethyl)-2-hexyl-3,5-dipentylpyridiriium chloride showed the greatest inhibitory activity. Least growth inhibition by pyridinium ions was observed for E. coli.
通过氨基酸和伯胺与烷烃的缩合反应,合成了 17 种烷基取代的季铵盐吡啶化合物。研究了这些吡啶鎓对革兰氏阴性和革兰氏阳性细菌(大肠杆菌和嗜热链球菌)以及霉菌(Neurospora crassa)和酵母菌(Candida utilis)的生长抑制能力。大多数吡啶鎓都能明显抑制受试微生物的生长。1-羧甲基-2-己基-3,5-二戊基吡啶鎓甜菜碱和 1-(2-羟乙基)-2-己基-3,5-二戊基吡啶鎓氯化物的抑制活性最强。吡啶鎓离子对大肠杆菌的生长抑制作用最小。
