“…However, as far as 5-MOP is concerned, although its use in association with Ultraviolet A irradiation for skin diseases is known from a long time [46], to the best of our knowledge, this is the first report of its direct anti-inflammatory effect in the absence of irradiation, whose mechanisms require further investigation. As far as the clinical indication of the lead compounds identified here to cure the chronic lung disease of patients affected by cystic fibrosis, consensus is growing on the need of intervening in parallel on the three major pathophysiological issues of CF lung pathology [47], that is the basic defect of ion transport regulation and airway surface fluid hydration, the chronic bacterial colonization by P. aeruginosa and the excessive inflammatory response, which contributes to the progressive damage of the respiratory tissue and lung function insufficiency. Thus potential clinical application of molecules such as 5-MOP, an already FDA-approved drug, as an anti-inflammatory molecule for cystic fibrosis patients deserves further investigation in pre-clinical and clinical studies.…”
