BACKGROUND Thiazolidine-2, 4-diones (TZDs) have become a pharmacologically important class of heterocyclic compounds since their introduction in the form of glitazones into the clinical use for the treatment of type 2 diabetes. TZDs lower the plasma glucose levels by acting as ligands for gamma peroxisome proliferators-activated receptors. In addition, this(More)
A series of nine new compounds of 5-((3-(aryl)-1-phenyl-1H-pyrazol-4-yl)methylene)-3-phenylthiazolidine-2,4-diones was synthesized by Knoevenagel condensation of various 3-(aryl)-1-phenyl-1H-pyrazole-4-carbaldehydes with 3-phenylthiazolidine-2,4-dione in ethanol in the presence of piperidine as a catalyst. The reaction afforded the desired products in good(More)
In the present study, poplar (Populus) wood is coated with intumescent formulation (ammonium polyphosphate/melamine/pentaerythritol), using acrylic resin as binder. Samples have also been prepared by adding fly ash (FA) in intumescent formulation at different loading levels. Thermal stability of composites has been studied with thermogravimetry, derivative(More)
Two series of compounds namely, dihydroindeno and indeno [1,2-e] [1,2,4]triazolo [3,4-b] [1,3,4]thiadizines (9a-l & 11a-l) were synthesized by cyclocondensation between α-bromoindanones (7a-b) or/and α,α-dibromoindanones (8a-b) and various 3-alkyl/aryl-4-amino-5-mercapto-1,2,4-s-triazoles (3a-f) in methanol with an aim to explore their effect on in vitro(More)
A series of 5-((3-aryl-1-phenyl-1H-pyrazol-4-yl)methylene)thiazolidine-2,4-diones was synthesized by Knoevenagel condensation of various 3-aryl-1-phenyl-1H-pyrazole-4-carbaldehydes (1a–h) with thiazolidine-2,4-dione (2) in ethanol in the presence of piperidine. All compounds were screened for their in vitro antibacterial (Staphylococcus aureus, Bacillus(More)
