analytical and spectral data. All the synthesized compounds were screened for their antibacterial activity and 3-3-(4-dimethylaminophenyl)acryloyl}-2H-chromen-2-one () was discovered to be the most active at minimum inhibitory concentration (MIC) value of 7.8 μg/mL. J. Heterocyclic Chem., (2010).
effects. The compound 1a molecules have π···πinteractions proved by short distance of 3.61(2) Å between the centroids of six-membered cycles and weak intermolecular C–H…O hydrogen bonds, which link the π···π dimers into columns. According to quantum chemical calculations by TD DFT method with the B3LYP functional, in the def2-TZVP basis, intermolecular π···πinteractions lead to strong red-shift (around

Synthesis and pharmacological evaluation of a novel series of 5-(substituted)aryl-3-(3-coumarinyl)-1-phenyl-2-pyrazolines as novel anti-inflammatory and analgesic agents
A novel series of 5-(substituted)aryl-3-(3-coumarinyl)-1-phenyl-2-pyrazolines (3a–l) were synthesized by reacting various substituted 3-aryl-1-(3-coumarinyl)propan-1-ones (2a–l) with phenylhydrazine in the presence of hot pyridine. Structures of all new synthesized compounds were characterized on the basis of elemental analysis and spectral data (IR, 1H NMR and 13C NMR). The title compounds were screened
