    Prostatitis is a common prostate disease that could be promoted by bacterial or non-bacterial infectious agents. 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.

    Phytochemical and Pharmacological Profile of Origanum Sipyleum Extracts: Exploring Novel Sources for Potential Pharmaceutical, Food, and Cosmetic Applications

    Origanum sipyleum L., an endemic plant of Western Anatolia has been used as a medicinal tea, food additive, and for the production of essential oil. In this study, the biological potential of three extracts (ethyl acetate, methanol, and aqueous) of O. sipyleum was assessed based on antioxidant activity against key enzymes of clinical relvance. The chemical profile of the plant was assessed using spectrophotometric and LC-MS techniques. Additionally, we explored potential antioxidant and anti-inflammatory effects duced by the extracts in an experimental model of ulcerative colitis induced by LPS challenging. LC-MS analysis revealed that the extracts contained different classes of phenolics, such as rosmarinic acid, phlorizin and gallic acid. We found that the aqueous extract was the most effective antioxidant, displaying the highest DPPH and ABTS scavenging, FRAP, CUPRAC, molybdenum(VI) reducing, and metal chelating effect. The aqueous extract howed the strongest acetylcholinesterase (AChE) inhibition; the methanol extract showed the highest ?-glucosidase inhibition, while the ethyl acetate extract was the most effective on butyrylcholinesterase (BChE), tyrosinase, and ?-amylase. The total flavonoid content was highest in the aqueous and ethyl acetate extract, respectively. Finally, we found that all extracts were effective in reducing LPS-induced activity of pro-oxidant and pro-inflammatory biomarkers including nitrites, LDH, PGE2 and 5-HT, in rat colon, with the best activity showed by ethyl acetate extract. Our results indicated that the three solvent extracts varied in their chemical and biological profiles, but overall, O. sipyleum showed promising therapeutic properties, nonetheless, need to be further validated in in vivo models.
