4-triazol-4-yl)piperidines and 1-alkyl-4-(2H-1,2,4-triazol-3-one-4-yl) piperidines were synthesized and their anticonvulsant and antibacterial activities were evaluated. Pharmacological tests showed that three of the synthesized compounds (6c, 6k, 7m) displayed 100% protection at a dose of 100 mg/kg. 4-(1- Octylpiperidin-4-yl)-2,4-dihydro-3H-1,2,4-triazol-3-one (6c) was the most active compound in this study
两个系列的1-烷基-4-(4H-1,2,4-三唑-4-基)哌啶和1-烷基-4-(2H-1,2,4-三唑-3-一-4-基)合成哌啶并评估其抗惊厥和抗菌活性。药理试验表明,三种合成化合物(6c,6k,7m)在100 mg / kg剂量下显示出100%的保护作用。4-(1-辛基哌啶-4-基)-2,4-二氢-3H-1,2,4-三唑-3-酮(6c)是本研究中活性最高的化合物,ED 50为65.4 mg / kg和TD 50值为241.2 mg / kg,PI值为3.6。四种合成的化合物对革兰氏阳性细菌金黄色葡萄球菌(RN4220,KCTC 209和KCTC 503)表现出有效的抑制活性,尤其是对耐多药临床分离株(MRSA3167 / 3506和QRSA3505 / 3519)具有抑制作用。其中,化合物1-tetradeyl-4-(4H-1,2,4-triazol-4-yl)哌啶(7f)对革兰氏阳性菌株的活性最高(MIC
