AIM The cooper(II) complex combination of N, N'-disalicylidenemethylenediamine and the Schiff bis base were investigated for anti-inflammatory activity. MATERIAL AND METHODS In vivo, the anti-inflammatory activity of the metallic complex in comparison with the activity of the Schiff bis base was tested by the method of Winter and co-workers using the Levy technique. RESULTS AND DISCUSSIONS ...
a new series of transition metal complexes of co(ii), ni(ii), cu(ii) and zn(ii), has beensynthesized from the knoevenagel condensate schiff base ligand(l) derived from β-ketoanilideand furfural with o-phenylenediamine and diethylmalonate. structural features were determinedby spectral and analytical techniques. square-planar geometry has been adopted by thecomplexes except cobalt complex which ...
the condensation reaction of 5-(4-aminophenyl)-4-phenyl-1,2,4-triazole-3-thione with salicylaldehyde, 4-hydroxybenzaldehyde, 5-chlorosalicylaldehyde, 5-bromosalicylaldehyde, 2-nitrobenzaldehyde, 3-nitrobenzaldehyde, 4-nitrobenzaldehyde and 4-methoxybenzaldehyde in methanol results in series of new schiff bases. the structure of schiff bases were confirmed by 1h nmr, 13c nmr, ir and mass spectro...
The coronavirus disease (COVID-19) is caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). As isatin-containing compounds exhibit several remarkable biological activities, isatin derivatives were prepared to combat global pandemic SARS-CoV-2 that gripping world. Herein, synthesis of novel has been reported. cytotoxic activities determined using cancer cell (MCF-7) and nor...
in this work we introduce a practical use of synthesized schiff base metal complex in sensing application. a new perchlorate-selective electrode based on the complex n, n'-4-nitro-phenylmethanebis-(salicylaldiminato) copper (ii) [cul] as the membrane carrier was developed. the electrode exhibits a good nernstian slope of -55.0 ± 1.0 mv/decade and a linear range of for perchlorate. the limit o...
The asymmetric unit of the title compound, C(22)H(28)N(2)O(3)·CH(4)O, consists of two independent Schiff base mol-ecules and two independent methanol solvent mol-ecules. In one Schiff base mol-ecule, the 2-hydr-oxy group forms an intra-molecular hydrogen bond with the amide O atom, whereas in the other Schiff base mol-ecule, the 2-hydr-oxy-substituted benzene ring is oriented so that the 2-hydr...
new hetero-binuclear hg-cu schiff base complexes were prepared by reaction of 2,2'-[1,1'-(2,2-dimethylpropane-1,3-diyldinitrilo)-diethyldyne]diphenolato}copper(ii) (cul1) and 6,6'-x-2,2'-[(2,2-dimethylpropane-1,3-diyl)bis(nitrilomethanylylidene)]diphenolato copper(ii) [(x = ethoxy (cul2) and methoxy (cul3)], with hgcl2 to give [cu(l1)hgcl2] (1), [cu(l2)hgcl2] (2), and [cu...
