describes the synthesis and antimicrobial activity evaluation of new pipemidic acid derivatives. New compounds were obtained on the basis of Mannich reaction of 4,5-disubstituted 1,2,4-triazole-3-thiones with pipemidic acid. Antimicrobial tests revealed high antibacterial activity of obtained derivatives. Gram-negative rods belonging to Enterobacteriaceae family were particularly most sensitive to new pipemidic
本文介绍了新型哌啶酸衍生物的合成和抗菌活性评价。在4,5-二取代的1,2,4-三唑-3-硫酮与哌啶酸的曼尼希反应的基础上获得了新化合物。抗菌试验表明获得的衍生物具有高抗菌活性。属于肠杆菌科的革兰氏阴性杆菌对新的哌啶酸衍生物特别敏感。合成的化合物对奇异变形杆菌 ATCC 12453、鼠伤寒沙门氏菌 ATCC 14028 和大肠杆菌 ATCC 25922 表现出非常强的活性。抑制这些细菌生长的新型哌啶酸衍生物的最低抑制浓度为 0.98–7.81 µg/ml,7.89 µg。 /ml 和 0.98–3.91 µg/ml,分别。
