Abstract
Benign prostatic hyperplasia (BPH), characterized by the enlargement of the prostate gland and subsequent lower urinary tract symptoms, poses a significant health concern for aging men with increasing prevalence. Extensive efforts encompassing in vitro and in vivo models are underway to identify novel and effective agents for the management and treatment of BPH. Research endeavors are primarily channeled toward assessing the potential of compounds to inhibit cell proliferation, curb inflammation, and display anti-androgenic activity. Notably, through screening aimed at inhibiting 5-alpha reductase type 2 (5αR2) in human prostatic cells, two acyl compounds (1 and 2) were isolated from a bioactive fraction sourced from an association of marine sponges Poecillastra sp. and Jaspis sp. The complete structure of 1 was determined as (Z)-dec-3-enony (2S, 3S)-capreomycidine, ascertained by JBCA and ECD comparison. While the absolute configurations of 2 remained unassigned, it was identified as a linkage of a 2, 7S*-dihydoxy-9R*-methyloctadecanoyl group with the 2-amino position of a tramiprosate moiety referred to as homotaurine. Evaluation of both compounds encompassed the assessment of their inhibitory effects on key biomarkers (5αR2, AR, PSA, and PCNA) associated with BPH in testosterone propionate (TP)-activated LNCap and RWPE-1 cells.

Abstract
PURPOSE Tomato is an important source of lycopene, a carotenoid that has been emerging as a natural preventive agent for prostate disease. Moreover, tomato contains other components with a wide range of physiological properties, but their potential beneficial effects on prostatic hyperplasia (PH) during obesity have not been completely established. In this study, we compared the effect of a lipidic extract of tomato saladette (STE) with Serenoa repens (SR) on obese rats with PH. METHODS Forty-eight Wistar rats were divided in Control (C) and Obese (Ob) treated without (n = 12) and with (n = 36) testosterone enanthate (TE), once a week for 8 weeks to induce PH. After 4 weeks, SR and STE were administered. Biochemical parameters, oxidative stress markers and inflammatory cytokines production were determined. RESULTS TE increased prostate weight and caused prostatic hyperplasia in C group, and these effects were exacerbated by obesity. SR and STE reverted the increase in prostate weight and hyperplasia caused by TE in C and Ob groups. Obesity increased LDL, TGs, NOx and MAD, but decreased HDLc, GSx, SOD and CAT. SR reverted the effects of obesity, but these were significantly reduced and HDLc increased with STE. Obesity and TE increased TNFα, IL-1β and IL-6 levels, but these were partially reverted by STE compared with SR. CONCLUSIONS Excess of fat tissue increases the alterations by PH. STE diminishes these alterations compared with SR, suggesting its beneficial effect to improve prostate function. Whole tomato lipid extract could serve as sole therapy or as an adjunct to pharmacological treatment for PH.

Abstract
Inhibition of 5α-reductase (5αR), which blocks the conversion of testosterone to its active metabolite, dihydrotestosterone, has been shown to impact further prostate enlargement (benign prostatic hyperplasia, or BPH). Clinical trials of standardized lipidosterolic extracts of Serenoa repens (LSESr), also known as standardized extracts of saw palmetto, have demonstrated improvement in lower urinary tract symptoms (LUTS) and delayed progression of BPH. The aim of this preclinical study was to compare two standardized LSESr, a proprietary ultrahigh-pressure supercritical carbon dioxide extract of S. repens (UHP-sCESr) and the well-established hexanic extract of S. repens (HESr), for both 5αR inhibition activity and lipid profiles. UHP-sCESr and HESr had nearly identical inhibition curves and comparable IC50 values for 5αR-1 (9.25 ± 0.87 and 9.86 ± 0.11 μg/mL, respectively; p = 0.43) and 5αR-2 (7.47 ± 0.07 and 7.72 ± 0.05 μg/mL, respectively; p = 0.0544). UHP-sCESr and HESr also had comparable lipid profiles based on similar total fatty acid levels (87.7% and 91.5%, respectively), weight/weight comparisons of individual fatty acids, and individual fatty acid ratios to lauric acid. In addition, UHP-sCESr meets the standard set by the United States Pharmacopeia (USP) monograph for authenticity and purity for a supercritical carbon dioxide (SCCO2) extract of saw palmetto, whereas HESr meets the standard set by the European Medicines Agency (EMA) for a well-established medicinal product. In conclusion, based on enzyme inhibition curves and IC50 values, a standardized lipid profile is important to achieve comparable mechanisms of action for lipidosterolic extracts of saw palmetto. UHP-sCESr offers a comparable, standardized LSESr for men with LUTS/BPH in regions where the proprietary HESr is not available.

Abstract
Benign prostatic hyperplasia (BPH) is a nonmalignant growth of the prostate tissue and causes urinary tract symptoms. To provide effective treatment, tamsulosin (TM), saw palmetto oil (SP), and pumpkin seed oil (PSO) were combined and fabricated a nanostructured lipid carrier (NLC) as TM-S/P-NLC using experimental design. The purpose was to enhance the permeation and therapeutic activity of TM; combining TM with SP and PSO in an NLC generates a synergistic activity. An optimized TM-S/P-NLC was obtained after statistical analysis, and it had a particle size, percentage of entrapment efficiency, and steady-state flux of 102 nm, 65%, and 4.5 μg/cm2.min, respectively. Additionally, the optimized TM-S/P-NLC had spherical particles with a more or less uniform size and a stability score of 95%, indicating a high level of stability. The in vitro release studies exhibited the optimized TM-S/P-NLC had the maximum release profile for TM (81 ± 4%) as compared to the TM-NLCs prepared without the addition of S/P oil (59 ± 3%) or the TM aqueous suspension (30 ± 5%). The plasma TM concentration–time profile for the TM-S/P-NLC and the marketed TM tablets indicated that when TM was supplied in a TM-S/P-NLC, the pharmacokinetic profile of the drug was improved. Simultaneously, in vivo therapeutic efficacy studies also showed favorable results for the TM-S/P-NLC in terms of the prostate weight and prostate index following treatment of BPH. Based on the findings of present study, we suggest that in the future, the TM-S/P-NLC could be a novel drug delivery system for treating BPH.

Abstract
Saw palmetto extract (SPE) has been widely used as a therapeutic remedy for urinary dysfunction in western countries. Furthermore, as an herb drug, it can be used as an alternative therapy for benign prostatic hyperplasia (BPH) due to its safety and minimum adverse effects. Reportedly, SPE improves the urinary symptoms, which mainly depend on anti-androgenic effects and effects on autonomic receptors in the lower urinary tract. However, the mechanisms of action responsible for the therapeutic roles of SPE have not been fully elucidated. Relevant studies indicate that SPE has some positive effects on the treatment of urological diseases in animals, and clinical trials are ongoing. In this review, we summarize the pharmacological properties and discuss the possible therapeutic mechanisms of SPE in urological diseases, including anti-androgenic effects, effects on autonomic receptors in the lower urinary tract, anti-inflammatory activity, anti-proliferative and pro-apoptotic effects, and highlight a potential therapeutic approach in the clinical treatment of patients with BPH, prostate cancer, chronic prostatitis (CP) and erectile dysfunction (ED).

A double blind, placebo-controlled randomized comparative study on the efficacy of phytosterol-enriched and conventional saw palmetto oil in mitigating benign prostate hyperplasia and androgen deficiency. BMC Urol 2020; 20:86. [PMID: 32620155 PMCID: PMC7333342 DOI: 10.1186/s12894-020-00648-9] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2020] [Accepted: 06/19/2020] [Indexed: 02/06/2023] Open
Abstract
Background The present clinical trial was conducted to evaluate the efficacy and tolerability of a standardized saw palmetto oil containing 3% β-sitosterol in the treatment of benign prostate hyperplasia (BPH) and androgen deficiency. Methods Subjects aged 40–65 years with symptomatic BPH were randomized to 12-week double-blind treatment with 500 mg doses of β-sitosterol enriched saw palmetto oil, conventional saw palmetto oil and placebo orally in the form of capsules (n = 33 in each group). BPH severity was determined using the International Prostate Symptom Score (IPSS), uroflowmetry, serum measurement of prostate specific antigen (PSA), testosterone and 5α-reductase. During the trial, the androgen deficiency was evaluated using Aging Male Symptoms (AMS) scale, the Androgen Deficiency in the Aging Male (ADAM) questionnaire, serum levels of free testosterone. Results Subjects treated with β-sitosterol enriched saw palmetto oil showed significant decrease in IPSS, AMS and ADAM scores along with reduced postvoiding residual volume (p < 0.001), PSA (p < 0.01) and 5α-reductase from baseline to end of 12-week treatment as compared to placebo. There was also a significant increment in the maximum and average urine flow rate (p < 0.001), and serum free testosterone level of subjects treated with enriched saw palmetto oil as compared to placebo. Conclusion This study demonstrates the efficacy of β-sitosterol enriched saw palmetto oil superior to conventional oil thus extending the scope of effective BPH and androgen deficiency treatment with improved quality of life through the intake of functional ingredients.
