Some new isatin3hydrazone derivatives that are Isatin3(benzylidene)hydrazone, Isatin3-(methyl ethylide)hydrazone, isatin 3-(isoproplylidene)hydrazone have been synthesized from the reaction of isatin3-hydrazone and different aldehydes and ketones. Thestructure of synthesized compound is assigned on the basis of, IR, 1HNMR, 13CNMRdata. The anti microbial activity was done by disk diffusion metho...

Isatin is an endogenous compound identified in humans that possesses a wide range of biological activities. Isatin has anxiogenic, sedative, anticonvulsant activities and acts as a potent antagonist on atrial natriuretic peptide receptors in vitro. A series of p-substituted isatin semicarbazones have shown anticonvulsant activity in MES, scPTZ and scSTY tests. Various isatin-N-Mannich bases of ...

In the title compound, C(14)H(10)FN(3)O, the six- and five-membered rings of the isatin moiety and the six-membered ring of phenyl-hydrazone are nearly planar with r.m.s. deviations of 0.0003, 0.0004 and 0.007 Å, respectively. The dihedral angle between the phenyl ring and the isatin ring system is 6.09 (9)°. The mol-ecular structure is stabilized by a strong intra-molecular N-H⋯O hydrogen bond...

In this work, a series of novel Mannich's bases incorporated with Ibuprofen core and Biginelli derivatives have been reported. The synthesis process was dependent on linking hydrazone Isatin to via methylene group formaldehyde. new compounds characterized using FT-IR spectroscopy, 1H-NMR spectroscopy the physical properties.

Some new 3-[(5-benzylidene-2-phenyl)-3, 5-dihydro-4-H-imidazol-4-one-3-(4-bezoylhydrazono)]-indole-2-ones (VIII) have been synthesized from different isatinhydrazones (II) by condensing with 2-phenyl-5-benzylidene- 3-N (4-acetyl phenyl)-1, 5-dihydro-imidazol-4-one (VII).

BACKGROUND The importance of the isatinic quinolyl hydrazones arises from incorporating the quinoline ring with the indole ring. Quinoline ring has therapeutic and biological activities whereas, the indole ring occurs in Jasmine flowers and Orange blossoms. As a ligand, the isatin moiety is potentially ambidentate and can coordinate the metal ions either through its lactam or lactim forms. In a...

Recently, we have reported a series of isatin hydrazone, two them, namely, 3-((2,6-dichlorobenzylidene)hydrazono)indolin-2-one (1) and 3-((2-chloro-6-fluorobenzylidene)hydrazono)indolin-2-one (2) having potent cytotoxicity, showing cyclin-dependent kinases (CDK2) inhibitory activity bearing recommended drug likeness properties. Since both compounds (1 2) showed against CDK2, assumed it would al...

A novel series of isatin-s-triazine hydrazone derivatives has been synthesized and reported herein. The synthetic methodology involved the reaction s-triazine hydrazine precursors with isatin in presence CH3COOH as a catalyst EtOH solvent to afford corresponding target products 6a-e high yields purities. characterization data obtained from elemental analysis, FT-IR, NMR (1H- 13C-) were full agr...
