Abstract

The aim of this study was to examine of antibacterial and antifungal activity of 2-amino-3-cyanopyridine derivatives against some microorganisms. The investigated compounds 2, 4, 6 exhibit promising antibacterial and antifungal activities. The high biological activities of the indicated compounds can be probably caused by the simultaneous presence of bromine atoms, nitro and amino groups in the molecules.

Abstract

The corrosion inhibition activities 2.4-dimethylasetophenone semicarbazone (1), 2.4-dimethylacetophenone thiosemicarbazone (2), (E)-3-(2-allyloxy)phenyl)-1-(4-hydroxy-2-methylphenyl)prop-2-en-1-one (3), (E,E)-3-(5-bromo-2-hydroxy­phe­nyl)-1-(4-hydroxy-2-methylphenyl)prop-2-en-1-one th­i­­­­o­se­­mi­car­bazone (4) and 3-hydroxy-3-(2-(2-hydroxy-5-methylphenyl)-2-oxoethyl)indolin-2-one (5) have been studied by weight loss measu­rements for mild steel-3 specimen in diesel fuel. The corrosion rates of the steel-3 are decreased with the increase of the carbazones, chalcone, indolinone con­cen­tra­ti­on, while the inhibition efficiencies are increased.
