New Schiff bases, hydrazones and semicarbazones derived from 1,2-dihydro-4-hydroxy-6-methyl2-oxoquinoline-3-carbaldehyde, have been synthesized. The semicarbazone was subjected to react with 2,3-dichloroquinoxaline, chloroacetic acid, and oxalyl chloride affording multiaza­ heterocycles substituted to quinolone moiety at position 3. Condensation of the 2-imidazolidinethione derivative with some...

This review presents an analysis of different algorithms for predicting the sensory ability organic compounds towards metal ions based on their chemical formula. A database chemosensors containing information various classes suitable compounds, including dipyrromethenes, BODIPY, Schiff bases, hydrazones, fluorescein, rhodamine, phenanthroline, coumarin, naphthalimide derivatives, and others (a ...

Transition metal complexes containing Schiff base ligands are of interest to model the active sites of biologically important molecules. In particular, Schiff base derivatives of hydrazones exhibit various bioactivities and play vital role in certain physiological functions as well. Hydrazones and their metal complexes exhibit wide range of biological and pharmaceutical activities that includes...

Hydrazones are a special class of organic compounds in the Schiff base family. Hydrazones constitute a versatile compound of organic class having basic structure (R1R2C=NNR3R4). The active centers of hydrazone, that is, carbon and nitrogen, are mainly responsible for the physical and chemical properties of the hydrazones and, due to the reactivity toward electrophiles and nucleophiles, hydrazon...

New Schiff bases derivatives from lauric acid were synthesized through the condensation of dodecane methyl ester with hydrazine to give corresponding hydrazide, which react aromatic aldehyde afford dodecanehydrazide-hydrazones and carbon disulfide 1,3,4-oxadiazole-2-thion. The chemical structures confirmed by numerous characterization methods; including Infrared, Ultraviolet-Visible, 1H 13C Nuc...

to develop novel antimycobacterial agents, a new series of thiazolidinone-azole hybrids 4a-b, 5a-b and 6-13 were designed and synthesized. thiazolidin-4-ones (4a-b and 5a-b) were obtained by the reaction of schiff bases and hydrazones (2a-b and 3a-b) with mercaptoacetic acid. 5-benzylidene derivatives (6-13) were gained by treatment of 5a-b with appropriate benzaldehydes according to knoevenage...
