A simple and rapid reversed-phase high-performance liquid-chromatographic method for the separation and determination of process-related impurities of celecoxib (CXB) in bulk drugs and pharmaceuticals was developed. The separation of impurities viz., 4-methylacetophenone (I), 1-(4-methylphenyl)-4,4,4-trifluorobutane-1,3-dione (II), 4-hydrazinobenzene sulfonamide (III) and a regio-specific isome...

Molecules of 5-methyl-2-phenyl-6,7-dihydrobenzo[h]pyrazolo[1,5-a]quinazoline, C21H17N3, (I), are linked into chains by a combination of a C-H...pi(arene) hydrogen bond and a pi-pi stacking interaction; in the closely related 5-methyl-2-(4-methylphenyl)-6,7-dihydrobenzo[h]pyrazolo[1,5-a]quinazoline, C22H19N3, (II), there are no hydrogen bonds and the molecules are linked into centrosymmetric dim...

transfusion-dependent patients such as those suffering from β-thalassaemia develop a fatal secondary haemosiderosis and consequently a selective iron chelator must be used to relieve such iron overload. 3- hydroxypyridin-4-ones are selective for iron(iii) under most biological conditions, but unlike desferrioxamine, are efficiently absorbed when administered orally. in this study, the synthesis...

In this study, a series of twenty-two ring-substituted naphthalene-1-carboxanilides were prepared and characterized. Primary in vitro screening of the synthesized carboxanilides was performed against Mycobacterium avium subsp. paratuberculosis. N-(2-Methoxyphenyl)naphthalene-1-carboxamide, N-(3-methoxy-phenyl)naphthalene-1-carboxamide, N-(3-methylphenyl)naphthalene-1-carboxamide, N-(4-methylphe...

The two title compounds, 2-([(1Z)-[4-(dimethylamino)phenyl]methylene]amino)-4,5-dimethyl-N-(2-methylphenyl)thiophene-3-carboxamide, C(23)H(25)N(3)OS, (I), and 2-([(1E)-[4-(dimethylamino)phenyl]methylene]amino)-N-(4-methylphenyl)-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxamide,C(25)H(27)N(3)OS, (II), show antibacterial and antifungal activities. The asymmetric unit of (II) contains two crystal...
