Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Synthetic studies of fused pyrimidine have been reported extensively because of their structural diversity and association with a wide spectrum of biological activity. It has been observed over the years that poly substituted pyrimido[1,2-a]benzimidazoles possess a wide spectrum of biological activities and they are structurally related to natural purine bases. With this background we have prepared a library of imidazopyrimidine analogues by one pot Biginelly type multi-component reaction. The process has several advantages like neat reaction and easy workup and purification steps. All the synthesized compounds were evaluated for their antimicrobial activity. The investigation of antimicrobial and anti-fungal screening data revealed that all the tested compounds showed moderate to significant activity.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Pyrimidine is a well known hetero-cyclic compound, which has been subjected to a large variety of structural modification in order to synthesize derivatives with different biological properties. Pyrimidine derivatives have been reported to possess a broad spectrum of pharmacological properties. Pyrimidine is the most important member of all the diazines as this ring system occurs widely in living organisms. Purines, uric acid, barbituric acid and some anti-malarial and anti-bacterial agents also contain the pyrimidine ring.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - An efficient protocol to synthesized a small library of N-aryl pyrazoles via C-N bond Chan-Lam coupling reaction using diverse boronicacids at room temperature using Cu(OAc)2/TEA as a catalytic system without utilization of any ligand or additive and exposed to air to afford moderate to excellent yield. The characterizations of newly synthesized compounds were confirmed by FTIR, MS, 1H NMR, 13C NMR, and elemental analysis. All the synthesized compounds were assayed for their antibacterial activity against Staphylococcus aureus MTCC-96, Escherichia coli MTCC-443, B. subtilis MTCC-441, S. typhi MTCC-98, and antifungal activity against Aspergillus niger MTCC-282 and Aspergillus clavatus MTCC-1323 at different concentration and compared with standards drugs. The minimum inhibition concentration (MIC) of the compounds was studied by micro broth dilution method.…
