[PMID: 36760474 PMCID: PMC9904897 DOI: 10.1155/2023/1777631] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 12/01/2022] [Accepted: 12/13/2022] [Indexed: 02/01/2023]
Abstract
The objective of the present study was to develop a novel nanogel containing Beta vulgaris L. hydroalcoholic extract and assess its efficacy for treating testosterone-induced alopecia. Beta vulgaris L. leaf hydroalcoholic extract nanogel (BVEN) was prepared by ionic gelation method, incorporated in carbopol 934 gel. Optimization of particle size and entrapment efficiency as the responses was carried out by central composite design response surface methodology. Prepared nanoparticles were evaluated for entrapment efficiency, particle size, zeta potential, polydispersity index, Fourier transform infrared spectroscopy, transmission electron microscopy, and differential scanning calorimetry. Nanogel was evaluated for pH, colour, appearance and homogeneity, viscosity, spreadability, in vitro release study, and stability studies. Further, 2.5% and 5% BVEN were also evaluated for antialopecic activity in Swiss albino mice by using parameters as hair growth initiation, testosterone content, total protein, prostate weight measurement, hair follicular density, anagen/telogen ratio, and histopathological studies. The resulting nanoparticles had better entrapment efficiency with particle size of 274 nm, polydispersity index of 0.259, and zeta potential of +28.8. BVEN pH 6.5, drug content, i.e., quercetin 99.84 ± 1.30% and stigmasterol 99.89 ± 1.52%, spreadability 20.3 ± 0.5925 g cm/sec, and viscosity 110 × 105 cps were observed. Stability studies showed that nanogel was stable at 4°C ± 2°C/60% ± 5% RH. It was found that 5% BVEN showed better antialopecic activity as compared to 2.5% BVEN.

Abstract
Hair health is associated with personal distress and psychological well-being. Even though hair loss (alopecia) does not affect humans' biological health, it affects an individual's social well-being. So, treatment for hair problems and improving hair health are obligatory. Several pharmacological and cosmeceutical treatment procedures are available to manage hair loss and promote growth. Several factors associated with hair health include genetics, disease or disorder, drugs, lifestyle, chemical exposure, and unhealthy habits such as smoking, diet, and stress. Synthetic and chemical formulations have side effects, so people are moving towards natural compounds-based remedies for their hair problems. The history of using phytochemicals for hair health has been documented anciently. However, scientific studies on hair loss have accelerated in recent decades. The current review summarizes the type of alopecia, the factor affecting hair health, alopecia treatments, phytochemicals' role in managing hair loss, and the mechanisms of hair growth-stimulating properties of phytochemicals. The literature survey suggested that phytochemicals are potent candidates for developing treatment procedures for different hair problems. Further detailed studies are needed to bring the scientific evidence to market.

Abstract
Cuscuta reflexa is an extensive leafless, parasitic climber that has been used since ancient times for various purposes and as a therapeutic plant in different areas of Pakistan. The phytochemical, antibacterial, antioxidant, and fatty acid investigations were carried out on the leaves, stems, and fruit extracts of C. reflexa. Preliminary phytochemical screening has shown the presence of various phytochemicals such as carbohydrates, protein, amino acids, alkaloids, flavonoids, phenols, glycosides, saponins, tannins, terpenoids, steroids, and phenolic compounds. The percentage variation of some components fluctuated like moisture (6.85-10.34%), ash (5.38-7.83%), acid insoluble ash (0.28-0.71%), water-soluble ash (0.78-0.96%), hexane extractives (1.23-1.91%), alcohol extractives (10.39-12.23%), water extractives (25.34-30.35%), loss on drying (1.16-1.47%) and crude fiber (15.04-18.26%) for leaves, stems, and fruits respectively. The level of free fatty acid was different as follows: leaves (2.37%), stems (2.16%), and fruits (2.94%); a high value of peroxide was observed in stems, followed by leaves and fruits. The iodine and saponification values in leaves, stems, and fruits were found in the range of 105-116 g I2/100 g, and 165-175 mg KOH/g. The antibacterial activity was carried out by the disc diffusion method against gram-positive Staphylococcus aureus and gram-negative Escherichia coli bacteria. It was found that all extracts of the selected plant were most active against E. coli with a zone of inhibition of 4, 4, and 6 at MIC 250 as compared to S. aureus, which showed a zone of inhibition of 3, 4, and 5 at MIC 250 µg/ml. The antioxidant potential of the leaves, stems, and fruit extracts, examined on the basis of their scavenging activity of free radicals, was found to be good. The result of the gas chromatography-mass spectroscopy (GC-MS) analysis reveals that linoleic acid (38.10–40.53%) is the most abundant fatty acid of C. reflexa and the smallest amount was found in tricosanoic acid (0.12-0.19%). In general, the isolated compounds were reported to possess anticarcinogenic, antitumor, antimicrobial, and anti-inflammatory properties. It was concluded that C. reflexa has a markedly therapeutic potential to heal wounds and may provide the pharmacological basis for its folk uses.

Elicitation of Submerged Adventitious Root Cultures of Stevia rebaudiana with Cuscuta reflexa for Production of Biomass and Secondary Metabolites. Molecules 2021; 27:molecules27010014. [PMID: 35011247 PMCID: PMC8746614 DOI: 10.3390/molecules27010014] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Revised: 11/30/2021] [Accepted: 12/16/2021] [Indexed: 11/19/2022] Open
Abstract
Stevia rebaudiana is an important medicinal plant that belongs to the Asteraceae family. The leaves of Stevia rebaudiana are a rich source of many health-promoting agents such as polyphenols, flavonoids, and steviol glycoside, which play a key role in controlling obesity and diabetes. New strategies such as the elicitation of culture media are needed to enhance the productivity of active components. Herein, the Cuscuta reflexa extracts were exploited as elicitors to enhance the productivity of active components. Cuscuta reflexa is one of the parasitic plants that has the ability to elongate very fast and cover the host plant. Consequently, it may be possible that the addition of Cuscuta reflexa extracts to adventitious root cultures (ADR) of Stevia rebaudiana may elongate the root more than control cultures to produce higher quantities of the desired secondary metabolites. Therefore, the main objective of the current study was to investigate the effect of Cuscuta reflexa extract as a biotic elicitor on the biomass accumulation and production of antioxidant secondary metabolite in submerged adventitious root cultures of Stevia rebaudiana. Ten different concentrations of Cuscuta reflexa were added to liquid media containing 0.5 mg/L naphthalene acetic acid (NAA). The growth kinetics of adventitious roots was investigated for a period of 49 days with an interval of 7 days. The maximum biomass accumulation (7.83 g/3 flasks) was observed on medium containing 10 mg/L extract of Cuscuta reflexa on day 49. As the concentration of extract increases in the culture media, the biomass gradually decreases after 49 days of inoculation. In this study, the higher total phenolics content (0.31 mg GAE/g-DW), total flavonoids content (0.22 mg QE/g-DW), and antioxidant activity (85.54%) were observed in 100 mg/L treated cultures. The higher concentration (100 mg/L) of Cuscuta reflexa extract considerably increased the total phenolics content (TPC), total phenolics production (TPP), total flavonoids content (TFC), total flavonoids production (TFP), total polyphenolics content (TPPC), and total polyphenolics production (TPPP). It was concluded that the extract of Cuscuta reflexa moderately improved biomass accumulation but enhanced the synthesis of phenolics, flavonoids, and antioxidant activities. Here, biomass’s independent production of secondary metabolites was observed with the addition of extract. The present study will be helpful to scale up adventitious roots culture into a bioreactor for the production of secondary metabolites rather than biomass accumulation in medicinally important Stevia rebaudiana.

Abstract
Background Androgenetic alopecia (AGA) is the most common form of non‐scarring alopecia in humans. Several studies have used different laboratory models to study the pathogenesis and interventions for AGA. These study models have proved beneficial and have led to the approval of two drugs. However, the need to build on existing knowledge remains by examining the relevance of study models to the disease. Objective We sought to appraise laboratory or pre‐clinical models of AGA. Method We searched through databases (PubMed, ScienceDirect, Web of Science, World CAT, Scopus and Google Scholar) for articles on AGA‐related studies from 1942 to March 2019 with a focus on study models. Results The search rendered 101 studies after screening and deduplication. Several studies (70) used in vitro models, mostly consisting of two‐dimensional monolayer cells for experiments involving the characterization of androgen and 5‐alpha reductase (5AR) and inhibition thereof, the effects of dihydrotestosterone (DHT) and biomarker(s) of AGA. Twenty‐seven studies used in vivo models of mice and monkeys to investigate DHT synthesis, the expression and inhibition of 5AR and hair growth. Only four studies used AGA‐related or healthy excisional/punch biopsy explants as ex vivo models to study the action of 5AR inhibitors and AGA‐associated genes. No study used three‐dimensional [3‐D] organoids or organotypic human skin culture models. Conclusion We recommend clinically relevant laboratory models like human or patient‐derived 3‐D organoids or organotypic skin in AGA‐related studies. These models are closer to human scalp tissue and minimize the use of laboratory animals and could ultimately facilitate novel therapeutics.

Evaluation of the anti-diarrheal effects of the whole plant extracts of Cuscuta reflexa Roxb in pigeons. Toxicol Rep 2021; 8:395-404. [PMID: 33717992 PMCID: PMC7921875 DOI: 10.1016/j.toxrep.2021.02.013] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2020] [Revised: 02/16/2021] [Accepted: 02/20/2021] [Indexed: 01/22/2023] Open
Abstract
The antidiarrheal activity of C. reflexa was evaluated in pigeons using the juice, aqueous, and methanol extracts. The antidiarrheal effect of C. reflexa was evaluated using different reported research models. The juice, aqueous, and methanol extract of C. reflexa exhibit significant anti-motility and anti-secretory potential.
Background Cuscuta reflexa (dodder) belonging to the family Convolvulaceae has many ethno-medicinal uses such as antidiarrheal and antiemetic. This plant has been employed to treat diarrhea, where the antidiarrheal use of this plant is well established in different communities around the world without scientific bases. In addition, the antibacterial, anthelmintic, anticholinergic, and antihistaminic effects of this parasitic vine are partly responsible for the folkloric antidiarrheal use of this plant. In the present study, the antidiarrheal activity of C. reflexa was evaluated in pigeons (Columba livia) using the juice (JCR), aqueous (CRAE), and methanol (CRME) extracts. Methods The antidiarrheal effect of C. reflexa was evaluated using different reported research models, with few modifications. In pigeons, diarrhea was induced by administration of castor oil (6 mL/kg, PO), ampicillin (250 mg/kg, IP), magnesium sulfate (2 gm/kg, PO), and cisplatin (6 mg/kg, IV). In these experiments, loperamide (2 mg/kg, IM) was used as a positive control, whereas JCR (1 mL/kg (1%) and 1 mL/kg (2%), CRAE (50, 100 and 200 mg/kg) and CRME (50, 100 and 200 mg/kg) were administered intramuscularly at different doses into each pigeon in the test groups. Results In addition to cisplatin-induced diarrhea, all paradigms tested gave significant results (P < 0.01). The JCR, at different doses, exhibited a significant (p < 0.01) a dose-dependent antidiarrheal effect on both the frequency and the onset of diarrhea. Similarly, CRAE and CRME, at doses of 100 and 200 mg/kg, showed considerable (p < 0.001) inhibition against the onset and frequency of diarrhea. On the other hand, JCR, CRAE, and CRME exerted significant effects (p < 0.001) on the percentage inhibition (PI) of diarrhea and gastrointestinal charcoal transit in a dose-dependent manner. In this respect, the maximum PI (p < 0.01) of JCR, CRAE, and CRME in different experimental paradigms was 43.13, 49.14, and 55.99 %, respectively. Conclusions Taken all together, results from this study reveal that the juice, aqueous, and methanol extract of C. reflexa exhibit significant anti-motility and anti-secretory potential. These findings may explain the medicinal use of C. reflexa in folk medicine as an antidiarrheal medicinal plant.

Cuscuta reflexa Roxb. Expedites the Healing Process in Contact Frostbite. BIOMED RESEARCH INTERNATIONAL 2020; 2020:4327651. [PMID: 33083466 PMCID: PMC7556107 DOI: 10.1155/2020/4327651] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/23/2019] [Revised: 02/19/2020] [Accepted: 07/07/2020] [Indexed: 11/17/2022]
Abstract
Frostbite is caused due to extreme vulnerability to cold, resulting in damage of deeper and superficial tissues alike. In this study, we report the anti-inflammatory and wound-healing properties of aqueous methanolic extract of Cuscuta reflexa (Cs.Cr) against contact frostbite. Thirty rats were divided into five groups including three treatment groups with increasing doses of Cs.Cr, a standard drug group receiving acetylsalicylic acid (ASA), and a metal bar-induced frostbite group. Frostbite injury was induced by a 3 × 3.5 cm metal bar frozen up to -79°C on shaved skin for continuous 3 minutes. Wounded area percentages were recorded to measure the healing rate in response to Cs.Cr administration. Haematological parameters and malondialdehyde content were also noted. On treatment with Cs.Cr, the healing rate is drastically increased and lipid peroxidation product malondialdehyde was decreased in a dose-dependent manner. Results were compared with frostbite and ASA (standard drug group). These results indicate that Cs.Cr possesses excellent wound-healing properties against frostbite injury and can prove to be a prospective compound in such conditions.

Abstract
Cuscuta reflexa has been traditionally used as an antiemetic. Additionally, it has been used in various herbal formulations for the treatment of emesis. So far, there is no scientific evidence of the plant extract as antiemetic. Therefore, this study was intended to assess the antiemetic activity of Juice (JCR), aqueous (CRAE) and methanolic extract (CRME) of C. reflexa in pigeons. Emesis was induced through GIT irritants like ampicillin (300 mg/kg, IM), copper sulphate (100 mg/kg, PO), conc. sodium chloride solution (1600 mg/kg, PO) and cisplatin (5-HT3 receptor stimulator) (6 mg/kg, IM). Dimenhydrinate acted as a positive control (2 mg/kg; IM). JCR [(1 ml/kg (1 %) and 1 ml/kg (2 %)], CRAE, and CRME were administered intramuscularly at different doses (50, 100 and 200 mg/kg) to each pigeon (n = 6). In each group, calculation of total number of jerks & vomiting episodes, and vomiting-weight was carried out to evaluate its antiemetic activity. The JCR exhibited a significant (p < 0.05) antiemetic impact on both the frequency and onset of emesis at 1 ml/kg (2 %) against various emesis mediator, except sodium chloride. Similarly, CRAE and CRME elicited marked dose dependent inhibition both on onset and frequency of emesis with highly significant (p < 0.001) effect at 200 mg/kg. The study reflects that juice, aqueous and methanolic extract of C. reflexa have significant antiemetic potential and possess pharmacological active constituent(s) that interfered with the emetic mediators by acting through GIT irritation and 5-HT3 receptor stimulations. Results of this study provide a scientific background to its traditional antiemetic uses.

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.

Unveiling Pharmacological Responses and Potential Targets Insights of Identified Bioactive Constituents of Cuscuta reflexa Roxb. Leaves through In Vivo and In Silico Approaches. Pharmaceuticals (Basel) 2020; 13:ph13030050. [PMID: 32245131 PMCID: PMC7151675 DOI: 10.3390/ph13030050] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Revised: 03/18/2020] [Accepted: 03/19/2020] [Indexed: 01/02/2023] Open
Abstract
Cuscuta reflexa Roxb. is traditionally used by the indigenous communities of Bangladesh to treat different diseases, such as pain, edema, tumor, jaundice, and skin infections. This study tested neuro-pharmacological, anti-nociceptive, and antidiarrheal activities by in vivo and in silico experiments for the metabolites extracted (methanol) from the leaves of Cuscuta reflexa (MECR). During the anxiolytic evaluation analyzed by elevated plus maze and hole board tests, MECR (200 and 400 mg/kg) exhibited a significant dose-dependent reduction of anxiety-like behavior in mice. Similarly, mice treated with MECR demonstrated a dose-dependent decrease in the time of immobility in both forced swimming and tail suspension tests. In addition, anti-nociceptive activity was assessed by the chemical-induced (acetic acid and formalin) pain models. In both cases, 400 mg/kg was found to be most effective and significantly (p < 0.001) inhibited acetic acid stimulated writhing and formalin-induced licking (pain response) in mice. Furthermore, antidiarrheal efficacy determined by the castor-oil induced diarrheal model manifested an evident inhibition of diarrheal stool frequency. In parallel, previously isolated bioactive compounds were documented based on the biological activities and subjected to in silico studies to correlate with the current pharmacological outcomes. The selected isolated compounds (15) displayed favorable binding affinities to potassium channels, human serotonin receptor, COX-1, COX-2, M3 muscarinic acetylcholine receptor, and 5-HT3 receptor proteins. Additionally, the ADME/T and toxicological properties were justified to unveil their drug-like properties and toxicity level. Overall, Cuscuta reflexa is bioactive and could be a potential source for the development of alternative medicine.

Abstract
This is an extensive review on epiphytic plants that have been used traditionally as medicines. It provides information on 185 epiphytes and their traditional medicinal uses, regions where Indigenous people use the plants, parts of the plants used as medicines and their preparation, and their reported phytochemical properties and pharmacological properties aligned with their traditional uses. These epiphytic medicinal plants are able to produce a range of secondary metabolites, including alkaloids, and a total of 842 phytochemicals have been identified to date. As many as 71 epiphytic medicinal plants were studied for their biological activities, showing promising pharmacological activities, including as anti-inflammatory, antimicrobial, and anticancer agents. There are several species that were not investigated for their activities and are worthy of exploration. These epipythes have the potential to furnish drug lead compounds, especially for treating cancers, and thus warrant indepth investigations.

Abstract
Cuscuta, commonly known as dodder, is a genus of family convolvolaceace. Approximately 170 species of Cuscuta are extensively distributed in temperate and subtropical areas of the world. Species of this genus are widely used as essential constituents in functional foods and traditional medicinal systems. Various parts of many members of Cuscuta have been found efficacious against a variety of diseases. Phytochemical investigations have confirmed presence of biologically active moieties such as flavonoids, alkaloids, lignans, saponines, phenolics, tannins, and fatty acids. Pharmacological studies and traditional uses of these plants have proved that they are effective antibacterial, antioxidant, antiostioporotic, hepatoprotective, anti-inflammatory, antitumor, antipyretic, antihypertensive, analgesic, anti hair fall, and antisteriogenic agents.

Abstract
BACKGROUND Androgenic alopecia (AGA) is a major type of human scalp hair loss, which is caused by two androgens: testosterone (T) and 5α-dihydrotestosterone (5α-DHT). Both androgens bind to the androgen receptor (AR) and induce androgen-sensitive genes within the human hair dermal papilla cells (HHDPCs), but 5α-DHT exhibits much higher binding affinity and potency than T does in inducing the involved androgen-sensitive genes. Changes in the induction of androgen-sensitive genes during AGA are caused by the over-production of 5α-DHT by the 5α-reductase (5α-R) enzyme; therefore, one possible method to treat AGA is to inhibit this enzymatic reaction. METHODS RT-PCR was used to identify the presence of the 5α-R and AR within HHDPCs. A newly developed AGA-relevant HHDPC-based assay combined with non-radioactive thin layer chromatography (TLC) detection was used for screening crude plant extracts for the identification of new 5α-R inhibitors. RESULTS HHDPCs expressed both 5α-R type 1 isoform of the enzyme (5α-R1) and AR in all of the passages used in this study. Among the thirty tested extracts, Avicennia marina (AM) displayed the highest inhibitory activity at the final concentration of 10 μg/ml, as the production of 5α-DHT decreased by 52% (IC50 = 9.21 ± 0.38 μg/ml). CONCLUSIONS Avicennia marina (AM) was identified as a potential candidate for the treatment of AGA based on its 5α-R1-inhibitory activity.

Abstract
BACKGROUND Androgenetic alopecia (AGA) is one of the most common chronic problems seen by dermatologists worldwide. It is characterized by progressive hair loss, especially of scalp hair, and has distinctive patterns of loss in women versus men, but in both genders the central scalp is most severely affected. It often begins around puberty and is known to effect self-esteem and the individual's quality of life. In contrast to the high prevalence of AGA, approved therapeutic options are limited. In addition to the scarce pharmacologic treatments, there are numerous nonprescription products claimed to be effective in restoring hair in androgenetic alopecia. OBJECTIVES The purpose of this paper is to review published medical and non-medical treatments for male and female AGA using the American College of Physicians evidence assessment methods. MEDLINE, EMBASE and Cochrane Library were searched for systematic reviews, randomized controlled trials, open studies, case reports and relevant studies of the treatment of male and female AGA. The relevant articles were classified according to grade and level of evidence. RESULTS The medical treatments with the best level of evidence classification for efficacy and safety for male AGA are oral finasteride and topical minoxidil solution. For female AGA, topical minoxidil solution appears to be the most effective and safe treatment. The medical treatments corresponding to the next level of evidence quality are some commonly used therapeutic non-FDA-approved options including oral and topical anti-hormonal treatments. Surgical treatment of follicular unit hair transplantation is an option in cases that have failed medical treatment although there is high variation in outcomes. LIMITATIONS Some articles, especially those concerning traditional herbs claimed to promote hair regrowth, were published in non-English, local journals. CONCLUSIONS An assessment of the evidence quality of current publications indicates that oral finasteride (for men only) and topical minoxidil (for men and women) are the best treatments of AGA.

Abstract
INTRODUCTION Androgenic alopecia (AGA) is the major type of scalp hair loss affecting 60 - 70% of the population worldwide. It is caused by two potent androgens, namely testosterone (T) and 5α-dihydrotestosterone (5α-DHT). Till date, only two FDA-approved synthetic drugs, minoxidil and finasteride, are used to cure AGA with only 35 and 48% success, respectively; therefore, a search for new drug based on the mechanism of androgens action is still needed. AREAS COVERED Relevant literature was reviewed to identify current therapeutic targets and treatments for AGA. The potential targets are classified into three categories: i) 5α-reductase; ii) androgen receptor and iii) growth-factor-producing genes related to hair growth. EXPERT OPINION Relevant assay systems using the right targets are required in order to obtain specific and effective drugs for AGA treatment. It is unlikely that single targeted agents will be sufficient for treating AGA, and therefore, it would be a challenge to obtain compounds with multiple activities.

Abstract
Avicennia marina (AM) exhibits various biological activities and has been traditionally used in Egypt to cure skin diseases. In this study, the methanolic heartwood extract of AM was evaluated for inhibitory activity against 5α-reductase (5α-R) [E.C.1.3.99.5], the enzyme responsible for the over-production of 5α-dihydrotestosterone (5α-DHT) causing androgenic alopecia (AGA). An AGA-relevant cell-based assay was developed using human hair dermal papilla cells (HHDPCs), the main regulator of hair growth and the only cells within the hair follicle that are the direct site of 5α-DHT action, combined with a non-radioactive thin layer chromatography (TLC) detection technique. The results revealed that AM is a potent 5α-R type 1 (5α-R1) inhibitor, reducing the 5α-DHT production by 52% at the final concentration of 10 µg/mL. Activity-guided fractionation has led to the identification of avicequinone C, a furanonaphthaquinone, as a 5α-R1 inhibitor with an IC50 of 9.94 ± 0.33 µg/mL or 38.8 ± 1.29 µM. This paper is the first to report anti-androgenic activity through 5α-R1 inhibition of AM and avicequinone C.

Abstract
Pumpkin seed oil (PSO) has been shown to block the action of 5-alpha reductase and to have antiandrogenic effects on rats. This randomized, placebo-controlled, double-blind study was designed to investigate the efficacy and tolerability of PSO for treatment of hair growth in male patients with mild to moderate androgenetic alopecia (AGA). 76 male patients with AGA received 400 mg of PSO per day or a placebo for 24 weeks. Change over time in scalp hair growth was evaluated by four outcomes: assessment of standardized clinical photographs by a blinded investigator; patient self-assessment scores; scalp hair thickness; and scalp hair counts. Reports of adverse events were collected throughout the study. After 24 weeks of treatment, self-rated improvement score and self-rated satisfaction scores in the PSO-treated group were higher than in the placebo group (P = 0.013, 0.003). The PSO-treated group had more hair after treatment than at baseline, compared to the placebo group (P < 0.001). Mean hair count increases of 40% were observed in PSO-treated men at 24 weeks, whereas increases of 10% were observed in placebo-treated men (P < 0.001). Adverse effects were not different in the two groups.

Abstract
BACKGROUND Benincasa hispida Cogn. has been used traditionally in India for the management of urinary disorders. The fruit of B hispida is used as a diuretic and the seeds have been reported to possess antiangiogenic effects in prostate cells. OBJECTIVE The aim of the present study was to examine the effect of petroleum ether extract, ethanolic extract, and B hispida seed oil on hyperplasia of the prostate induced by the subcutaneous administration of testosterone in rats. METHODS In vitro studies were performed to determine the 5α-reductase inhibitory potential of the extracts. The results of those studies paved the way for the pharmacologic screening of the extracts to assess their potential against testosterone-induced hyperplasia in rats. Nine groups containing 10 rats per group were created for this study. Hyperplasia was induced by administration of testosterone (3 mg/kg SC) for 14 days in all the groups except the vehicle-treated group. Simultaneous administration of petroleum ether extract (100 or 200 mg/kg PO), ethanolic extract (100 or 200 mg/kg PO), and B hispida seed oil (20 or 40 mg/kg PO) was conducted. A standard 5α-reductase inhibitor (ie, finasteride) was used as a positive control. The weight of the rats was recorded on day 0 (ie, day 1 of the study) and on day 14, and the influence of testosterone and test extracts on the weight of the rats was determined. On day 14, rats were euthanized; prostates were dissected out, and weighed. The rats' prostate/body weight (P/BW) ratio was then determined. Histologic examinations were performed on prostates from each group. RESULTS The petroleum ether extract as well as B hispida seed oil exhibited inhibition of 5α-reductase activity in in vitro studies. Ethanolic extract did not exhibit significant inhibitory potential in vitro. Further in vivo study found that testosterone treatment significantly increased the rats' P/BW ratio in all the groups except the vehicle-treated rats, and this increase in weight was significantly inhibited in rats administered petroleum ether extract (100 and 200 mg/kg PO) and B hispida seed oil (20 and 40 mg/kg PO). Ethanolic extract did not exhibit any significant activity. CONCLUSIONS Petroleum ether extract and B hispida seed oil inhibited testosterone-induced hyperplasia of the prostate in these rats. Further studies are needed to evaluate its effect in humans with benign prostatic hyperplasia.

Abstract
This study demonstrates 5α-reductase inhibitory activity of certain herbs useful in the management of androgenic disorders. Ganoderma lucidum (Curtis) P. Karst (GL), Urtica dioica Linn. (UD), Caesalpinia bonducella Fleming. (CB), Tribulus terrestris Linn. (TT), Pedalium murex Linn. (PM), Sphaeranthus indicus Linn. (SI), Cuscuta reflexa Roxb. (CR), Citrullus colocynthis Schrad. (CC), Benincasa hispida Cogn. (BH), Phyllanthus niruri Linn. (PN) and Echinops echinatus Linn. (EE) were included in the study. Petroleum ether, ethanol and aqueous extracts of these herbs were tested for their 5α-reductase inhibitory activity against the standard 5α-reductase inhibitor, finasteride. A biochemical method to determine the activity of 5α-reductase was used to evaluate the inhibition of different extracts to the enzyme. The optical density (OD) value of each sample was measured continuously with ultraviolet spectrophotometer for the reason that the substrate NADPH has a specific absorbance at 340 nm. As the enzyme 5α-reductase uses NADPH as a substrate, so in the presence of 5α-reductase inhibitor, the NADPH concentration will increase with the function of time. This method thus implicates the activity of 5α-reductase. The method proved to be extremely useful to screen the herbs for their 5α-reductase inhibitory potential. GL, UD, BH, SI and CR came out to be promising candidates for further exploring their antiandrogenic properties.

Abstract
Cuscuta reflexa Roxb. is a golden yellow, leafless, perennial, parasitic herb of the family Convolvulaceae. C. reflexa has been investigated for antispasmodic, hemodynamic, anticonvulsant, anti steroidogenic, antihypertensive, muscle relaxant, cardiotonic, antiviral, antibacterial, antioxidant, cholinergic, diuretic and hair growth activities. Many chemical constituents have been isolated from C. reflexa such as cuscutin, amarbelin, β-sitosterol, stigmasterol, kaempferol, dulcitol, myricetin, quercetin, coumarin and oleanolic acid. This review presents a detailed survey of the literature on pharmacognosy, phytochemistry and traditional and biological medicinal uses of C. reflexa.
