Chemical constituents and biological activities of the genus Zanthoxylum: A review

Zanthoxylum known as “Timoor” is used as mouth fresh, tooth care, spice and in intoxicating of the fishes. The present study deals with documentation of isolated chemical constituents and biological activities of the genus Zanthoxylum. The chemical constituents and essential oil have been isolated and characterized by several analytical methods. Alkaloids and cumarins are the main constituents...

Synthesis of benzothiazoyl salicylate moieties

Aminosalicylates are derivatives of the highly functionalized compound aminosalicylic acid. Benzothiazoyl salicylates were obtained in this work from the highly functionalized aminosalicylic acid by reacting ammonium thioureas as a nucleophile to aminosalicylates that were derived from aminosalicylic acid and bromine was used as the cyclising agent. Results obtained indicated that it was the brominated cyclised product...

Facile green synthesis of 2, 4-substituted -2, 3- dihydro -1, 5 Benzothiazepine derivatives as novel anticonvulsant and central nervous system (CNS) depressant agents

The present work reports eco friendly synthesis of 2, 4-substituted -2, 3- dihydro -1,5-benzothiazepine derivatives as novel anticonvulsant and central nervous system (CNS)depressant agents having lesser side effects. Facile, one pot efficient, solvent free microwave-assisted green synthesis of 1, 5-benzothiazepine derivatives by cyclo- condensation of 2-aminothiophenol with 1, 3-substituted-prop-2-en-1-one (2a-h)...

Sodium nano-particle effects on montmorillinite structure

The main aim of the work is to study the expansion of the inter-layers clay to see what will happen to the mechanical properties of clays. The expansion of clay layers with sodium nano- particles makes for the exfoliation and dispersion of the crystal in fine particles in the clay positions. Patterns obtained by X-ray diffraction (XRD) of nano montmorillinite (MMT) illustrate that its shape is irregular and the range of...
