Synthesis and antibacterial activity of pyridylselenium compounds: Self-assembly of bis(3-bromo-2-pyridyl)diselenide via intermolecular secondary and π⋯π stacking interactions
摘要:
Various pyridylseleniums and their hydrochloride salts have been synthesized and evaluated for their antibacterial activities. SEM, TEM and enzyme profiling techniques have been used to investigate the mode of action of these compounds as antibiotics. Single crystal X-ray study of bis(3-bromo-2-pyridyl) diselenide (6b) has also been reported. The molecule 6b displays pi center dot center dot center dot pi stacking and pi center dot center dot center dot Br secondary interactions leading to a supramolecular self-assembly. A search on Cambridge Structural Database was undertaken to identify the pi center dot center dot center dot pi stacking interactions in various other bis(2-pyridyl) diselenides. (C) 2014 Elsevier B.

sodium borohydride in ethanol. The ethyl pyridyl/naphthyl/(diphenyl)methylseleno substituted alkanoates (8–13) on basic hydrolysis and subsequent acidification afford pyridyl/naphthyl/(diphenyl) methylseleno substitutedalkanoicacids (20–25) in excellent yields. These selenoalkanoates (8–13) and selenoalkanoic acids (20–25) have been characterized by elemental analysis and various spectroscopic techniques
