Modular Access to N-Substituted cis-3,5-Diaminopiperidines
摘要:
A sequence of oxidative cleavage/reductive amination/hydrogenolysis enables the preparation of N-substituted cis-3,5-diaminopiperidines from a readily available bicyclic hydrazine. This new synthetic route provides a simple and general access to RNA-friendly fragments with a good chemical diversity.
Synthesis and biological evaluation of new N-(2-hydroxy-4(or 5)-nitro/aminophenyl)benzamides and phenylacetamides as antimicrobial agents
摘要:
A new series of N-(2-hydroxy-4(or 5)-nitro/aminophenyl)benzamide and phenylacetamide derivatives (la-In, 2a-2n) were synthesized and evaluated for antibacterial and antifungal activities against Staphylococcus aureus, Bacillus subtilis, Klebsiella pneumoniae, Pseudomonas aeruginosa, Escherichia coli, Candida albicans, and their drug-resistant isolates. Microbiological results indicated that the compounds possessed a broad spectrum of activity against the tested microorganisms at MIC values between 500 and 1.95 mu g/ml. Benzamide derivative Id exhibited the greatest activity with MIC values of 1.95, 3.9, and 7.8 mu g/ml against drug-resistant B. subtilis, B. subtilis, and S. aureus, respectively.
