Oxidative stress and inflammation are commonly present in many chronic diseases. These responses are closely related to pathophysiological processes. The inflammatory process can induce oxidative stress and vice versa through the activation of multiple pathways. Therefore, agents with antioxidant and/or

Enantioselective association events between boronic acid receptors and bifunctional substrates such as alpha-hydroxycarboxylates and vicinal diols were exploited to develop enantioselective indicator-displacement assays. It was found that the sensitivity of the assay could be tuned by using either colorimetric or
