Novel Aminonaphthoquinone Mannich Bases Derived from Lawsone and their Copper(II) Complexes: Synthesis, Characterization and Antibacterial Activity
Uma série de novas Bases de Mannich (HL1-HL13) derivadas da 2-hidroxi-1,4-naftoquinona (lausona), benzaldeídos substituídos [C 6 H 2 RRRC(O)H] e várias aminas primárias (NH 2 R, R = n-butil, benzil, alil, 2-furfuril) e seus complexos de Cu, [Cu(L1) 2 ]-[Cu(L13) 2 ], foram sintetizados e caracterizados por métodos analíticos e espectroscópicos. As estruturas dos complexos 1 (R = R = R = H; R = B...
متن کاملSynthesis and Biological Activity of Certain Mannich Bases Derivatives from 1, 2, 4-Triazoles
Substituted 1, 2, 4- Triazoles have shown multiple biological activities such as anti-inflammatory, anti fungal, etc. 5-mercapto triazoles were prepared from the potassium dithiocarbazinates. These triazoles were used for preparation of different derivatives by two different schemes. In the first scheme the Mannich bases were prepared from 5- marcapto-s triazole Quinazolines. The 5-Marcato-s-Tr...
متن کاملSynthesis Characterization and Biological Activity Study of New Schiff and Mannich Bases and Some Metal Complexes Derived from Isatin and Dithiooxamide
Two new Schiff and Mannich bases, namely, 1-Morpholinomethyl-3(1' -N-dithiooxamide)iminoisatin (L(I)H) and 1-diphenylaminomethyl-3-1'-N-dithiooxamide)iminoisatin (L(II)H), were prepared from condensation reaction of new Schiff base 3-(1'-N-dithiooxamide)iminoisatin (SBH) with morpholine or diphenylamine respectively in presence of formaldehyde . The structures were characterized by IR, (1)HNMR,...
متن کاملAntioxidant Activity and Electrochemical Properties of Tetradentate Schiff Bases and Their Cd(II) Complexes
This study describes the effects of the substituents on electrochemical behavior and antioxidant activity of the three tetradentate Schiff bases, containing ethane-1,2- diamine, propane-1,3- diamine and butan-1,4- diamine as the amine part and salicylaldehyde, and corresponding Cd(II) complexes. Cyclic voltammograms of these compounds were recorded in dimethylsulfoxide and 0.1 M sodium perchlor...
متن کاملAntibacterial evaluation of some Schiff bases derived from 2-acetylpyridine and their metal complexes.
A series of Schiff bases derived from 2-acetylpyridne and their metal complexes were characterized by elemental analysis, NMR, FT-IR and UV-Vis spectral studies. The complexes were screened for anti-bacterial activity against Methicillin-resistant Staphylococcus aureus (MRSA), Acinetobacter baumanni (AC), Klebsiella pneumonie (KB) and Pseudomonas aeruginosa (PA) using the disc diffusion and mic...
