Synthesis and in vitro activity of 1,2,4-triazole-ciprofloxacin hybrids against drug-susceptible and drug-resistant bacteria
摘要:
A series of novel 1,2,4-triazole-ciprofloxacin hybrids was designed, synthesised and evaluated in vitro against drug-susceptible and drug-resistant bacteria. A significant part of the compounds obtained showed antibacterial activity higher than the activity of ciprofloxacin, both towards Gram-positive and Gram-negative species. Despite relatively small number of synthesised derivatives, it was possible to observe important dependences between their structure and activity. (C) 2012 Elsevier Masson SAS. All rights reserved.
Synthesis, characterization and preliminary anticonvulsant evaluation of some 4-alkyl-1,2,4-triazoles
摘要:
Designed and synthesized 4-alkyl-1,2,4-triazole-3-thione derivatives showed significant anticonvulsant activity, determined in the maximal electroshock-induced seizure (MES) test. The chemical structure of all new compounds was confirmed by spectral methods (H-1 NMR, C-13 NMR, IR, MS). A sensitive and selective method was elaborated for the determination of the anticonvulsant compounds levels in mice brain tissue, based on HPLC with diode array detector (DAD). Chromatographic tests showed that lack of anticonvulsant effect of two derivatives (15,16) with long alkyl chains at N-4 position of the 1,2,4-triazole ring was due to the inability to cross the blood brain barrier (BBB).
