[ 1 ] - Brønsted Acidic Phosphonium Based Ionic Liquid Functionalized SBA-15 [HO3S-PhospIL@SBA-15]: Green, Recyclable, and Efficient Catalyst for the Synthesis of Pyrano[3,2-c]Chromenone Derivatives

The surface of SBA-15 was modified by diphenylphosphine; then, it was treated with butane sultone and sulfuric acid to obtain Brønsted acid HO3S-phosphonium based ionic liquid functionalized SBA-15 with HSO4- as a counteranion. It efficiently catalyzed synthesis of pyrano[3,2-c]chromenone derivatives through the reaction of 4-hydroxycoumarin and chalcones at...

[ 2 ] - Synthesis and Biological Investigation of some Novel Sulfonamide and Amide Derivatives Containing Coumarin Moieties

New sulfonamide and amide derivatives containing coumarin moieties; oxo-2H-chromen-sulfamoylphenylacetamides and oxo-2H-chromen-arylacetamides were synthesized starting from diverse 2-chloroacetamide derivatives and a wide range of coumarins. The structures of the obtained compounds were elucidated by IR and NMR spectra and also analytical elemental analysis. In the next step, the above mention...

[ 4 ] - Potential Anti-obesity Effects of some Medicinal Herb: In vitro α-Amylase, α-Glucosidase and Lipase Inhibitory Activity

In this study, in vitro inhibitory activity of methanolic and chloroform extracts of some medicinal plants including C. wightii, T. ammi, N. sativa, C. arabica, L. usitatissimum, C. cyminum, and R. Graveolens was evaluated toward α-glucosidase, α-amylase, and lipase comparing with acarbose and orlistat as the standard inhibitors. Our results revealed that both methanolic and chloroform extracts...
