The present work focuses on the synthesis of novel heterocycles 2-(aryloxy)-3-(4,5-diaryl-1H-imidazol-2-yl)quinolines (6k-v) by an effective condensation reaction. These molecules exhibited fluorescent properties and hence for the proper understanding of their optical behavior and quantum yields, solvatochromic studies have been carried out. Further, frontier molecular orbitals, molecular electrostatic potential (MEP), and geometrical structure optimization have been investigated using the BLYP/6-311G ++ (d, p) method.

Background: Fifty percent glycerin preserves immunotherapy solution potency for at least 3 years but must be diluted before injection to reduce glycerin-induced pain and inflammation. We studied pain, erythema, induration, and bruises caused by glycerin (0% to 30%).
Methods: In 15 healthy subjects we compared, in double-blind fashion, pain scores, injection site erythema, induration, and bruising caused by subcutaneous injections in randomized order of 0.
