A series of new pyridazinylacetic acid derivatives were synthesized and have been investigated for their ability to inhibit the activity of the A and B isoforms of monoamine oxidase (MAO). All compounds were found to be more selective to the MAO-A isoform with compound 5d having the highest SI values. Computational study performed with a docking technique indicated the potential of these compou...

A highly efficient method for the synthesis of 2-hydroxy-2,3-dihydrofuran derivatives from 1,4-enediones and phenacyl pyridinium halides via a domino reaction has been developed. This is a simple and beneficial strategy for the construction of 2-hydroxy-2,3-dihydrofuran compounds from readily available starting materials under mild conditions. Moreover, the application of this reaction provides...

In the title coordination polymer, [HgBr(2)(C(14)H(10)N(4)S(2))](n), the Hg(II) atom is four-coordinated in a distorted tetra-hedral geometry by the two N atoms of the pyridyl groups of different 3,6-bis-(2-pyridyl-sulfan-yl)pyridazine ligands and two Br atoms. The bridging function of the cis ligands leads to a helical chain structure along [100].

The work described herein employs potassium hydroxide impregnated alumina (KOH-alumina) as a mild, efficient, and recyclable catalyst for a one-pot solvent-free and environmentally safer synthesis of 3,4,6-triarylpyridazines and some substituted pyridazines from active methylene carbonyl species, 1,2-dicarbonyls, and hydrazine hydrate by microwave (MW) irradiation. The method offers highly conv...

Abstract We report here synthetic approaches to access new classes of small molecules based on three heterocyclic scaffolds, i.e. 3,7-dihydropyrimido[4,5-d]pyridazine-4,8-dione, 1,8-naphthyridin-4(1 H )-one and 4H-pyrido[1,2-a]pyrimidin-4-one. The bi-cyclic structure 3,7-dihydropyrimido[4,5-d]pyridazine-4,8-dione is a heterocycle, described for the first time. In silico methodologies inverse vi...
