The reaction between 5-nitro-isatin and phenyl-hydrazine in acidic ethanol yields the title compound, C14H10N4O3, whose mol-ecular structure deviates slightly from a planar geometry (r.m.s. deviation = 0.065 Å for the mean plane through all non-H atoms). An intra-molecular N-H⋯O hydrogen bond is present, forming a ring of graph-set motif S(6). In the crystal, mol-ecules are linked by N-H⋯O and ...

The synthesis, structure, electrochemistry, and biological studies of Co(II), Ni(II), Cu(II), and Zn(II) complexes of thiocarbohydrazone ligand are described. The ligand is synthesized starting from thiocarbohydrazide and isatin. It is evident from the IR data that in all the complexes, only one part of the ligand is coordinated to the metal ion resulting mononuclear complexes. The ligand coord...

Schiff bases and phenyl hydrazone of isatins were prepared by reacting isatin and the appropriate aromatic primary amine/hydrazines. A new series of the corresponding N-mannich bases were synthesized by reacting them with formaldehyde and diphenylamine. The chemical structures were confirmed by means of their 1H-NMR, IR spectral data and elemental analysis. The compounds were screened for analg...

Isatin derivatives are one of most potent anticonvulsant agent of natural origin. It has display potent anticonvulsant effect in a wide variety of preclinical anticonvulsant models. Till date various isatin derivatives have been synthesized and evaluated for anticonvulsant activity. This review is an attempt to compile the medicinal chemistry of various synthesized isatin analogs. Isatin and it...

Isatin (2,3-dioxindole) is a benzopyrrole derivative that belongs to large class of heterocyclic chemicals. derivatives are essential synthetic substrates can be utilized as starting materials build wide range heterocycles with diverse applications in pharmaceutical sciences. therefore have recently gained lot attention. This review emphasizes on the Schiff base from isatin, isatin quinoline/fl...

There is evidence that the binding of deprenyl, a monoamine oxidase (MAO) B inhibitor, and other propargylamines to glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is primarily responsible for their neuroprotective and antiapoptotic effects. Thus, GAPDH may be a target for other neuroprotective drugs. Using two independent approaches, radioligand analysis and an optical biosensor technique, we...

Isatin, 1H-indole-2,3-dione, is a heterocyclic compound of significant importance in medicinal chemistry. It is a synthetically versatile molecule, a precursor for a large number of pharmacologically active compounds. Isatin and its derivatives have aroused great attention in recent years due to their wide variety of biological activities, relevant to application as insecticides and fungicides ...
