Inhibiting α-glucosidase is a reliable method for reducing blood sugar levels in diabetic individuals. Bis(dimethylamino)benzophenone derivatives 1–27 were synthesized from bis(dimethylamino)benzophenone via two-step reaction. Different spectroscopic techniques, including EI-MS and 1H NMR, employed to characterize all synthetic derivatives. The elemental composition of compounds was confirmed by analysis results found agreement with the calculated values. evaluated inhibitory activity,...

Background: Ferula ammoniacum (D. Don) is one of the endemic medicinal plants that traditionally used to treat a number diseases. Although plant has been enhance memory, investigational evidence supporting nootropic effect was unsubstantial. Hence, rationale for this study assess potential beneficial F. seed extracts on learning and memory in mice. Methods: The powdered samples (aerial parts) were subjected extraction ad fractionation. Among extracts, crude ethyl acetate screened major...
