A number of 1,2,3‐triazolylmethyl piperazino oxazolidinone derivatives with optionally varied substituents at the 4N‐piperazine position were synthesized and their antibacterial activity evaluated against a panel of susceptible and resistant Gram‐positive and selected Gram‐negative bacteria. Substitution with 5‐membered heteroaroyl and dinitrobenzoyl moieties potentiated activity against staphylococci
合成了许多在 4N-哌嗪位置具有不同取代基的 1,2,3-三唑基甲基哌嗪基恶唑烷酮衍生物,并评估了它们对一组敏感和耐药的革兰氏阳性菌和选定的革兰氏阴性菌的抗菌活性。用 5 元杂芳酰基和二硝基苯甲酰基部分取代可增强对葡萄球菌和肠球菌菌株的活性。此外,具有二硝基苯甲酰基 7n、7o 和 5-硝基呋喃酰基 7t 取代的化合物对卡他莫拉氏菌的效力是利奈唑胺的四到八倍。然而,在 4N-哌嗪位置取代胍基和其他水溶性官能团导致化合物缺乏抗菌活性。
