Synthesis and pharmacological evaluation of a novel series of cyclopentenone derivatives

A novel series of cyclopent-2-enone derivatives have been synthesised by the reaction of 4-hydroxy-3,4-diphenylcyclopent-2-enone, cyclic secondary amines, phosphorus reagents, hexamethylphosphoramide and Lawesson's reagent in boiling toluene/THF. The chemical structures of new compounds were identified by H-1 NMR, C-13 NMR, P-31 NMR and mass spectra. Furthermore, the structure of one of the synthesised compounds has been confirmed using single crystal X-ray diffraction. The pharmacological evaluation results of antilung and anticolon carcinoma cell line properties for the products are discussed.
