The mechanism of co-assembly of different aromatic dipeptides has been studied using a combination of microscopy and spectroscopy techniques. At an equimolar ratio, the kinetics of the process is favored giving rise to alternate copolymers.
Primary hyperoxaluria type 1 (PH1) is a rare life-threatening genetic disease related to glyoxylate metabolism and characterized by accumulation of calcium oxalate crystals. Current therapies involve hepatic and/or renal transplantation, procedures that have significant morbidity and mortality and require long-term immunosuppression. Thus, a pharmacological treatment is urgently needed. We introduce here an unprecedented activity of salicylic acid derivatives as agents capable of decreasing oxalate output in hyperoxaluric hepatocytes at the low micromolar range, which means a potential use in the treatment of PH1. Though correlation of this phenotypic activity with glycolate oxidase (GO) inhibition is still to be verified, most of the salicylic acids described here are GO inhibitors with IC values down to 3 μM. Binding mode of salicylic acids inside GO has been studied using in silico methods, and preliminary structure-activity relationships have been established. The drug-like structure and ease of synthesis of our compounds make them promising hits for structural optimization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
