IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca

IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.

AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.

Background/Aim: The identification of a series of oxadiazole-based compounds, as promising antiproliferative agents, has been previously reported. The aim of this study was to explore the SAR of newly-synthesized oxadiazole derivatives and identify their molecular targets. Materials and Methods: A small library of 1,2,5-oxadiazole derivatives was synthetized and their antiproliferative activity was tested by the MTT assay. Their interaction with topoisomerase I was evaluated and a molecular docking study was performed. Results: Several candidates showed cytotoxicity towards two human tumor cell lines, HCT-116 (colorectal carcinoma) and HeLa (cervix adenocarcinoma). Some derivatives exhibited inhibitory effects on the catalytic activity of topoisomerase I and this effect was supported by docking studies. Conclusion: The enzyme inhibition results, although not directly related to cytotoxicity, suggest that a properly modified 1,2,5 oxadiazole scaffold could be considered for the development of new anti-topoisomerase agents.
