The title compound, 2-amino 4-picolinium 4-nitrobenzoate (2A4PNB), has been identified as a nonlinear optical material and its good quality single crystals were grown from methanol solution. It crystallizes in monoclinic system with the non-centro symmetric space group
The inorganic cobaloximes of type [Co(Cl)(dmgH)2B]; where dmgH = dimethyl glyoxime and B =
neutral bases: glycine, ethyl amine, 2-aminopyridine, 4-aminopyridine, 2,6-diaminopyridine, aniline
and 1-napthylamine have been synthesized. The synthesized cobaloximes were characterized by IR,
UV-visible, 1H NMR and 13C NMR spectroscopic techniques. The cobaloxime complexes were screened
for their antibacterial activity against methicillin resistant Staphylococcus aureus (MRSA) and
Acinetobacter baumannii by the zone of inhibition test, biofilm eradication on biomaterial using catheter
and modified Congo red agar method. It has been found that the cobaloxime complexes exhibit inhibition
against both gram positive and gram negative bacteria and the cobaloximes showed better inhibition
towards Gram-negative bacteria compared to Gram-positive bacteria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
