Simple chalcones and bis-chalcones ethers as possible pleiotropic agents

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2015
The synthesis, the antioxidative properties and the lipoxygenase (LOX) and acetylcholinesterase (AChE) inhibition of a number of 4-hydroxy-chalcones diversely substituted as well as of a series of bis-chalcones ether derivatives are reported. The chalcones derivatives were readily produced using a Claisen-Schmidt condensation in a ultra sound bath in ...

4-({4-[(2E)-3-(2,5-Dimethoxyphenyl)prop-2-enoyl]phenyl}amino)-4-oxobutanoic Acid

open access: yesMolbank, 2017
A dimethoxy amide chalcone has been synthesized in a two-step reaction. First, an amine chalcone was synthesized by the reaction of 4′-aminoacetophenone and 2,5-dimethoxybenzaldehyde using 40% NaOH solution as a catalyst in ethanol, and then followed by ...

Synthesis, Antioxidant and Antimicrobial Activities of a Novel Series of Chalcones, Pyrazolic Chalcones, and Allylic Chalcones

open access: yesPharmacology & Pharmacy, 2011
A new series of chalcones (4a-c) and allylicchalcones (11a-b) have been prepared by the Claisen-Schmidt condensation. A novel series of pyrazolicchalcones (5a-c) have been synthesized by the reaction of respective chalcones (4a-c) and hydrazine hydrate.
