BACKGROUND Coumarin and their derivatives are important and useful compounds with diverse pharmacological properties. In the present study, we evaluated the in vitro cytotoxic activity of new acetoxycoumarin derivatives: 4-(7-methoxy-4-methyl-2-oxo-2H-chromen-3-yl)phenyl acetate (1), 4-(1-methyl-3-oxo-3H-benzo[f]chromen-2-yl)phenyl acetate (2), 4-(6-propionamido-4-methyl-2-oxo-2H-chromen-3-yl) ...

In the title compound, C(16)H(13)N(3)S, the pyrazoline ring forms dihedral angles of 6.89 (14) and 4.96 (11)° with the benzene ring and the benzothia-zole group, respectively. In the crystal, weak C-H⋯N inter-actions link the mol-ecules into chains extending along the b-axis direction.

reaction between aromatic aldehydes and 3–methyl-1-phenyl-2-pyrazoline-5-one catalyzed by nano-sio2/hclo4 in water under reflux provided a simple and efficient route for the synthesis of 4-((5-hydroxy-3-methyl-1-phenyl-1h-pyrazol-4-yl)(aryl)methyl)-3-methyl-1-phenyl-1h-pyrazol-5-ol derivatives in high yields.

Eight novel 1-[2-(1H-tetrazol-5-yl)ethyl]-1H-benzo[d][1,2,3]triazoles (3a-h) have been synthesized in order to obtain new compounds with potential anti-nociceptive and anti-inflammatory activity. The titled compounds were synthesized by the condensation of 1-[2-(1H-tetrazol-5-yl) ethyl]-1H-benzotriazole (2) and appropriate acid chlorides. Compound 2 was synthesized by reacting 3-(1H-benzo[d][1,...

A series of five-membered heterocyclic rings like Benzimidazole were synthesized by the reaction between benzene-1, 2 diamine and formic acid to form various derivatives (BD- BK) compounds was tested for their anti-inflammatory activity determined rat-paw- oedema method. All synthesis have been characterized 1HNMR, IR some Mass spectral data. The purified recrystallization entire compound gives...

The new polyheterocyclic compound, 2-benzyl-7-(4-chlorophenyl)-3-morpholino-6-((1-phenyl-1H-1,2,3-triazol-4-yl)methyl)-6,7-dihydro-5H-pyrrolo[3,4-b]pyridin-5-one, was synthesized by a sequential combination of 4-chlorobenzaldehyde, (1-phenyl-1H-1,2,3-triazol-4-yl)methanamine, 2-isocyano-1-morpholino-3-phenylpropan-1-one, and maleic anhydride under microwave-assisted one-pot process [Ugi-Zhu/aza...
