The Lack of Standardization and Pharmacological Effect Limits the Potential Clinical Usefulness of Phytosterols in Benign Prostatic Hyperplasia. PLANTS (BASEL, SWITZERLAND) 2023; 12:1722. [PMID: 37111945 PMCID: PMC10142909 DOI: 10.3390/plants12081722] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/18/2023] [Revised: 04/14/2023] [Accepted: 04/18/2023] [Indexed: 06/19/2023]
Abstract
The prevalence of benign prostatic hyperplasia (BPH) markedly increases with age. Phytotherapeutic approaches have been developed over time owing to the adverse side effects of conventional medications such as 5-reductase inhibitors and α1-adrenergic receptor antagonists. Therefore, dietary supplements (DS) containing active compounds that benefit BPH are widely available. Phytosterols (PSs) are well recognized for their role in maintaining blood cholesterol levels; however, their potential in BPH treatment remains unexplored. This review aims to provide a general overview of the available data regarding the clinical evidence and a good understanding of the detailed pharmacological roles of PSs-induced activities at a molecular level in BPH. Furthermore, we will explore the authenticity of PSs content in DS used by patients with BPH compared to the current legislation and appropriate analytical methods for tracking DS containing PSs. The results showed that PSs might be a useful pharmacological treatment option for men with mild to moderate BPH, but the lack of standardized extracts linked with the regulation of DS containing PSs and experimental evidence to elucidate the mechanisms of action limit the use of PSs in BPH. Moreover, the results suggest multiple research directions in this field.

JOURNAL OF ETHNOPHARMACOLOGY 2022; 284:114447. [PMID: 34737008 DOI: 10.1016/j.jep.2021.114447] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Revised: 07/15/2021] [Accepted: 07/21/2021] [Indexed: 06/13/2023]
Abstract
The genus Deverra DC. (Apiaceae) comprising only 13 taxa (9 species and 4 subspecies level) with disjunctive distribution in South Africa, in North Africa to Arabian Ecoregion. Thesis, books, Scientific journals, and reports were referred to collect information on the Deverra species. This present work reviewed the literature from 1900 to the end of January 2021. The aim of the review is to highlight traditional uses, phytochemistry and pharmacological properties of the species of the genus. The ethnopharmacologial uses of plant taxa belonging to this genus indicated that plant extracts, Essentail Oils (EOs) and infusion of aerial parts (APs) have been used in traditional popular medicine. The plants are used as a treatment of various purposes, such as asthma, rheumatism, fevers, hepatitis, diabetes and digestive difficulties. This present work focuses on ethnopharmacology of the Deverra species, the phytochemistry, pharmacology, toxicology among other studies on the genus. The present article summarizes on known and potential effects of the Deverra species as well as traditional medicine uses corroborated with pharmacological evidences. By the end of the review, Deverra species have a large application of bioactivities and the most described activities of Deverra plants are attributed to the presence of essential oils, coumarins, furocoumarins, flavonoids and phenolics. CONCLUSIONS: The review confirms that some Deverra taxa have been reported as a valuable source for flavoring and as a condiment as well as in the traditional medicine for the treatment of hypertension, to relief stomach pain and against intestinal parasites against spasms, pains, diabetes, hepatitis, digestive difficulties, urinary infections … etc. Nonetheless, for the valorisation of Deverra species in order to prevent and treat various diseases, further pharmacological investigations are strongly required to determine the mechanism of action, test the safety and the efficacity before starting clinical trials at big scale.

Abstract
Prostate cancer (CaP) is one of the leading causes of death in men worldwide. Much attention has been given on its prevention and treatment strategies, including targeting the regulation of 5-alpha-Reductase (5αR) enzyme activity, aimed to limit the progression of CaP by inhibiting the conversion of potent androgen dihydrotestosterone from testosterone that is thought to play a role in pathogenesis of CaP, by using the 5-alpha-Reductase inhibitors (5αRis) such as finasteride and dutasteride. However, 5αRis are reported to exhibit numerous adverse side effects, for instance erectile dysfunction, ejaculatory dysfunction and loss of libido. This has led to a surge of interest on plant-derived alternatives that might offer favourable side effects and less toxic profiles. Phytochemicals from plants are shown to exhibit numerous medicinal properties in various studies targeting many major illnesses including CaP. Therefore, in this review, we aim to discuss the use of phytochemicals namely phytosterols, polyphenols and fatty acids, found in various plants with proven anti-CaP properties, as an alternative herbal CaP medicines as well as to outline their inhibitory activities on 5αRs isozymes based on their structural similarities with current 5αRis as part of CaP treatment approaches.

Abstract
Androgenic alopecia (AGA) has a high incidence. Excess dihydrotestosterone in blood capillaries, which is converted from testosterone by 5α-reductase, is an AGA causative factor. We identified the inhibitory activity of four Polygonum multiflorum compounds against 5α-reductase via high-performance liquid chromatography, and the results showed that Physcion was a potent 5α-reductase inhibitor. Additionally, we found that through inhibiting 5α-reductase expression, Physcion could shorten the time of dorsal skin darkening and hair growth, improve hair follicle morphology, and significantly increase hair follicle count. Eventually, through molecular docking study, we found the binding energy and molecular interactions between Physcion and 5α-reductase type II. These results suggested that Physcion is a potent 5α-reductase inhibitor, as well as a new natural medicine for treating AGA.

Cho EC, Kim K. A comprehensive review of biochemical factors in herbs and their constituent compounds in experimental studies on alopecia. JOURNAL OF ETHNOPHARMACOLOGY 2020; 258:112907. [PMID: 32360043 DOI: 10.1016/j.jep.2020.112907] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/04/2020] [Revised: 04/17/2020] [Accepted: 04/21/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Alopecia is a chronic condition that may cause emotional and psychological distress to patients, which may significantly impact a patient's quality of life. As conventional treatments have only a transient therapeutic effect and result in unwanted side effects, many patients have attempted to find therapeutic herbs or compounds that function as safer and more potent treatments for alopecia. Many such herbs have been used in complementary and alternative medicine (CAM) for centuries; however, there is a lack of information on the therapeutic mechanisms of herbs used for the treatment of alopecia. AIM OF THE STUDY The aim of this review was to perform a critical assessment of the methods and results of experimental studies related to alopecia and to provide the potential mechanisms of action of herbs and their constituent compounds used in the identified studies, in particular, in relation to the stages of the cell cycle. We hope to better guide the clinical application and scientific research of herbs for the treatment of alopecia. MATERIALS AND METHODS We reviewed experimental studies to determine the methods used and the mechanism of action of the herbs and constituent compounds. Databases, including Medline (via PubMed), EMBASE, OASIS, and RISS, were searched for the following keywords: "medicinal plants," "alopecia," "alopecia areata," "androgenetic alopecia," "animal experiment," and "in vitro study." We also assessed the risks of bias, toxicity, and taxonomy to determine the quality of information. RESULTS C57BL/6 mice and human dermal papilla cells were the most commonly used models for in vivo and in vitro studies, respectively. Many herbs and their constituent compounds were used to treat alopecia by managing the hair cycle, keratinocyte proliferation, apoptosis, angiogenesis, hormones, and inflammation. These compounds prolong the anagen phase, shorten the transition from the telogen to phase anagen, and inhibit premature catagen phase. CONCLUSIONS This review has further elucidated the therapeutic mechanisms of herbs and their constituent compounds that are relevant to alopecia and discussed the effectiveness of using herbal treatments. There is a need to develop evidence regarding the quality control, taxonomy, and toxicology of these compounds. Such improvements will provide a better quality of evidence to ensure the efficacy and safety of herbs and compounds used for the treatment of alopecia.
