Synthesis and biological evaluation of new benzofuran carboxamide derivatives
A series of new 3-(glycinamido)-benzofuran-2-carboxamide and 3-(β-alanamido)-benzofuran-2-carboxamide derivatives (5a–o) were synthesized for the purpose of developing the new bioactive chemical entities and evaluated for their in vitro antimicrobial, anti-inflammatory and DPPH radical scavenging activities. The synthesized compounds were characterized by NMR, IR, Mass and X-ray crystallographic techniques
Selective synthesis of ureas and tetrazoles from amides controlled by experimental conditions using conventional and microwave irradiation
An efficient synthetic procedure has been achieved for selective synthesis of 1,5-disubstituted tetrazoles and diaryl ureas from secondary amides in situ in the presence of NaN3 and POCl3 as solvent, both by conventional and microwave methods. The reaction conditions were optimized to yield selectively either tetrazoles or urea derivatives from reasonable to excellent yields. These conversions have been tested and verified with various secondary amide precursors. The synthesized compounds were characterized by 1H NMR, 13C NMR and ESI-MS spectroscopic techniques
Evaluation of antimicrobial activity of glycinate and carbonate derivatives of cholesterol: Synthesis and characterization
A series of glycinate and carbonate derivatives of cholesterol (4a–t) were synthesized, characterized and assessed for their in vitro antimicrobial activity. Our results revealed that the compounds exerted inhibitory activities against gram-negative bacteria and fungi
