ABSTRACT There has been an increasing interest in the chemistry of pyridazinone derivatives because of their biological significance. Pyridazinones have been reported to possess variety of biological activities like antidiabetic, anticancer, anti-AIDS, cardiovascular, antiinflammatory, anticonvulsant and cerebroprotective, analgesics, antidepressant, anticonvulsant, antiasthmatic, anti-HIV1, an...

In the title compound, C21H24N2O2Si, the carbonyl group of the heterocyclic ring and the O atom of the silyl ether group are placed toward opposite sides and the tert-butyl and pyridazinone moieties are anti-oriented across the Si-O bond [torsion angle = -168.44 (19)°]. In the crystal, mol-ecules are assembled into inversion dimers through co-operative N-H⋯O hydrogen bonds between the NH groups...

To synthesize 4-chloro-5-methoxy-2-(b-trifluoroethyl)-3(2H)-pyridazinone (4), the reactions of 4-chloro-5-methoxy-3(2H)-pyridazinone (5) with RCH(2)CF(3)(R = I, TsO, MsO, TfO) in different solvents were studied. It was found that methyl group migration took place during this reaction. An oxonium salt 9 was suggested as the active intermediate for the formation of the byproduct 4-chloro-5-methox...

Inflammation is associated with the development of several diseases comprising cancer and cardiovascular disease. Agents that suppress cyclooxygenase (COX) lipoxygenase (LOX) enzymes, besides chemokines have been suggested to minimise inflammation. Here, a variety novel heterocyclic non-heterocyclic compounds were prepared from three furanone derivatives. The structures all synthesised confirme...

benzofuran as an important heterocyclic compound is extensively found in natural products as well as synthetic materials. since benzofuran drivatives display a diverse array of pharmacological activities, an interest in developing new biologically active agents from benzofuran is still under consideration. this review highlights recent findings on biological activities of benzofuran derivatives...

In the title compound, C21H24N2O2Si, a new pyridazin-3(2H)-one derivative, the carbonyl group of the heterocyclic ring and the O atom of the silyl ether are located on the same side of the pyridazinone ring and the C-C-O-Si torsion angle is -140.69 (17)°. In the crystal, mol-ecules are linked by pairs of strong N-H⋯O hydrogen bonds into centrosymmetric dimers with graph-set notation R 2 (2)(8)....

quinazolinones are a group of fused heterocyclic compounds which have valuable biological properties including cytotoxic, antibacterial and antifungal activities. thiazole group-containing compounds have been also reported to have a wide range of biological activities such as antitumor, anti-inflammatory, analgesic and antibacterial effects. due to valuable cytotoxic effects of both thiazole gr...

The pyridazine ring is present in various biologically active compounds and some pyridazine compounds have been reported as valuable cardiovascular agents. Benzimidazole-pyridazinone compound, 4,5-dihydro-6-[2-(4-methoxyphenyl)-1H-benzimidazole-5-yl]-5-methyl-3(2H)pyridazinone (pimobedan or vetmedin) is a potent cardiovascular agent. It is a non adrenergic, non-glycoside inotropic drug with vas...
