Simple chalcones and bis-chalcones ethers as possible pleiotropic agents
Journal 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 ...
