Molecules of 2-nitrobenzaldehyde hydrazone, C7H7N3O2, where Z' = 2, are linked by two N-H...N hydrogen bonds into isolated dimers, whereas in the isomeric 3-nitrobenzaldehyde hydrazone, where Z' = 1, the molecules are linked by one N-H...O hydrogen bond and one N-H...N hydrogen bond into a three-dimensional framework structure.

For the detection of Cd(II) in aquatic media, a novel dicyanomethylene dihydrofuran hydrazone(DCDHFH)-based colorimetric chemosensor was developed. DCDHFH prepared by an azo-coupling process involving diazonium chloride 2, 4-dichloroaniline and heterocyclic moiety bearing active methyl group. The chromophore showed strong solvatochromism depending on solvent polarity due to electronic delocaliz...

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...

The asymmetric unit of the title compound, C(8)H(6)N(2)O(2), contains two independent mol-ecules, the aromatic rings of which are oriented at a dihedral angle of 1.68 (3)°. Intra-molecular C-H⋯O hydrogen bonds result in the formation of two non-planar six-membered rings, which adopt envelope and twisted conformations. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-e...

N-(4-tert-butylbenzoyl)-2-hydroxy-1-naphthaldehyde hydrazone (BBNH) inhibits both the DNA polymerase and ribonuclease H (RNase H) activities of the human immunodeficiency virus type 1 reverse transcriptase. In this study, we show that BBNH binding impacts on the stability of the human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT) heterodimer. The Gibbs free energy of dimer di...
