In addition, inflammatory pathways involved in prostatitis have been increasingly studied, and herbal extracts endowed with anti-inflammatory effects are under investigation, individually or in combination, for their efficacy in alleviating the burden of inflammation, with possible improvements in symptoms. Serenoa repens (Serenoa), in combination with Crocus sativus (Crocus) and Pinus massoniana (Pinus), has previously shown to improve sexual function and limit urinary symptoms in patients suffering from concomitant erectile dysfunction and lower urinary tract symptoms. In this context, the aim of the present study is to evaluate the efficacy of Serenoa, Crocus and Pinus extracts, either alone or in combination, on immortalized prostate cells (PC3) and in an experimental model of bacterial prostatitis constituted by ex vivo prostate specimens challenged with lipopolysaccharide (LPS). We found that the tested extracts were able to reduce ROS production by PC3 cells and NF kappa B and PGE(2) activity in prostate specimens challenged with LPS. In addition, the pharmacological association of the extracts displayed synergistic effects indicating a rational use of the mixture of the tested extracts as a novel anti-oxidant and anti-inflammatory formulation in bacterial prostatitis. Finally, we performed analytical and in vitro evaluation to better characterize the phytochemical profile and the mechanism of action of selected secondary metabolites.eninfo:eu-repo/semantics/closedAccessSerenoa repensPinus massoniana Lamb.Crocus sativus L.PGE(2)NF kappa BROSViabilityArticle31353154128889734Q3WOS:000412687500001Q4
