Targeted screening of multiple anti-inflammatory components from Chrysanthemi indici Flos by ligand fishing with affinity UF-LC/MS. Front Pharmacol 2024; 15:1272087. [PMID: 38694923 PMCID: PMC11062130 DOI: 10.3389/fphar.2024.1272087] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Accepted: 04/02/2024] [Indexed: 05/04/2024] Open
Abstract
Chrysanthemi indic Flos (CIF) has been commonly consumed for the treatment of inflammation and related skin diseases. However, the potential bioactive components responsible for its anti-inflammatory and sensitive skin (SS) improvement activities, and the correlated mechanisms of action still remain unknown. In this work, it was firstly found that the CIF extract (CIFE) displayed arrestive free radical scavenging activity on DPPH and ABTS radicals, with no significant difference with positive control Trolox (p > 0.05). Then, compared to the negative group, CIFE markedly decreased the productions of the pro-inflammatory cytokines (IL-1β, IL-6, PEG2, TNF-α, IFN-γ, NO) in LPS induced RAW264.7 cells in a dose-dependent manner (p < 0.01). Besides, CIFE strongly inhibited the COX-2 and hyaluronidase (HAase) with the IC50 values of 1.06 ± 0.01 μg/mL and 12.22 ± 0.39 μg/mL, indicating higher inhibitory effect than positive control of aspirin of 6.33 ± 0.05 μg/mL (p < 0.01), and comparable inhibitory effect with indometacin of 0.60 ± 0.03 μg/mL, and ascorbic acid of 11.03 ± 0.41 μg/mL (p > 0.05), respectively. Furthermore, kinetic assays with Lineweaver-Burk plot (Michaelis Menten equation) suggested that CIFE reversibly inhibited the COX-2 and HAase, with a mixed characteristics of competitive and non-competitive inhibition. Thereafter, multi-target affinity ultrafiltration liquid chromatography-mass spectrometry (UF-LC/MS) method was employed to fast fish out the potential COX-2 and HAase in CIFE. Herein, 13 components showed various affinity binding degrees to the COX-2 and HAase, while those components with relative binding affinity (RBA) value higher than 3.0, such as linarin and chlorogenic acid isomers, were deemed to be the most bioactive components for the anti-inflammatory and SS improvement activities of CIFE. Finally, the interaction mechanism, including binding energy, inhibition constant, docking sites, and the key amino acids involved in hydrogen bonds between the potential ligands and COX-2/HAase were simulated and confirmed with the molecule docking analysis. In summary, this study showcased the prominent anti-inflammatory and SS improvement activities of CIF, which would provide further insights on this functional medicinal plant to be a natural anti-SS remedy.

In vitro contraceptive activities, molecular docking, molecular dynamics, MM-PBSA, non-covalent interaction and DFT studies of bioactive compounds from Aegle marmelos. Linn., leaves. Front Chem 2023; 11:1096177. [PMID: 36778035 PMCID: PMC9911112 DOI: 10.3389/fchem.2023.1096177] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Accepted: 01/09/2023] [Indexed: 01/27/2023] Open
Abstract
Introduction: Bioactive molecules from natural sources having contraceptive properties were excellent alternatives for modern hormonal contraceptives. Researchers around the world were working on identifying contraceptive leads targeting the male reproductive system rather than the usual female contraceptives. The lack of proper understanding on male contraceptive protein drug targets leads to insufficient evidence on activities of identified contraceptive compounds. The proteins specific to the male reproductive system and involved in sperm-egg fusion will be an excellent drug target to identify the male non-hormonal, reversible contraceptive leads. Inhibiting sperm hyaluronidase activity by natural non-hormonal compounds will lead to reversible and non-hormonal male contraception. The Aegle marmelos Linn. is one such important medicinal plant with valuable phytocompounds, used traditionally as a potential contraceptive measure. The in vivo experiments on leaf extracts of Aegle marmelos. Linn containing terpenes, sterols, and alkaloids shows prominent contraceptive activities. Moreover, this study explores the potential ability of the leaf extract on inhibiting the sperm hyaluronidase action with additional molecular details on the interaction between sperm hyaluronidases and three phytocompounds such as aegeline, marmin, and marminol. Material and methods: The in vitro hyaluronidase inhibition assay and Computer Assisted Sperm Analysis (CASA) were used to evaluate the male contraceptive properties of the Aegle marmelos Linn. leaf extract. To identify the interaction profile of aegeline, marmin, and marmenol on sperm cell hyaluronidases the in-silico methods such as molecular docking, Non-Covalent Interaction analysis, Molecular dynamics, and Molecular Mechanics Poisson Boltzmann Surface Area were used. Results and discussion: The results of in vitro hyaluronidase inhibition assay and Computer Assisted Sperm Analysis shows the inhibition of hyaluronidase enzymatic activity and reduced sperm activities in the presence of leaf extracts. After incubation with leaf extracts for about 30 minutes time intervals show, the motility drops from progressive to non-progressive and ended up with complete immotile in 100 μg/ml concentration of leaf extract. The results of molecular docking, Non-Covalent Interaction analysis, Molecular dynamics, and Molecular mechanics Poisson Boltzmann Surface Area show that the phytocompounds marmin, and aegeline have the potential ability to inhibit sperm hyaluronidase.

[PMID: 35847835 PMCID: PMC9277211 DOI: 10.1155/2022/5742431] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Revised: 04/20/2022] [Accepted: 06/14/2022] [Indexed: 11/17/2022] Open
Abstract
Benign prostatic hyperplasia (BPH) is a common disease that affects elderly men with various complications. This study evaluates the effects of an Iranian traditional herbal medicine “Atrifil and Oshagh gum” on BPH in male Wistar rats. Atrifil is a combination of three medicinal plants: Emblica officinalis Gaertn, Terminalia chebula Retz, and Terminalia bellerica Retz” extracts, and Oshagh gum is Dorema ammoniacum D. Dono gum. In this study, 30 male Wistar rats were divided into five groups: normal control, disease, finasteride, and extract with 300 and 600 mg/kg groups. The extract is a combination of hydroalcoholic Atrifil extract and Oshagh gum. All groups received intramuscular testosterone enanthate to induce BPH except the normal control group. On the twenty-eighth day, prostate glands were separated. Histopathological changes were observed. Furthermore, the prostate-specific antigen (PSA) and prostate weights were measured. The binding propensities of finasteride, equol, and flavonoids present in this extract such as quercetin, rutin, and kaempferol for 5α-reductase, estrogen receptor alpha and beta, and estrogen-related receptor gamma were assessed using in silico docking approach. Histopathological evaluation, biochemical parameter, and PSA level results indicated significant inhibition of accruing and progression of BPH in groups treated with 600 mg/kg extract (p < 0.01). Furthermore, molecular docking showed that rutin had a high affinity to bind the receptors 5α-reductase, estrogen receptor beta, and estrogen-related receptor gamma even more than finasteride, and on average, quercetin had a higher affinity to all these receptors. In the end, it can be concluded that Atrifil and Oshagh gum is effective in preventing BPH.

Assessment of antiandrogenic and antispermatogenic activity of Hedera nepalensis in adult male rats. Andrologia 2021; 54:e14353. [PMID: 34931341 DOI: 10.1111/and.14353] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Revised: 12/07/2021] [Accepted: 12/08/2021] [Indexed: 11/29/2022] Open
Abstract
The use of medicinal plants for fertility regulation has been prevalent worldwide for many centuries. They possess natural substances having antiandrogenic properties and can be used as source of contraception. In the current study, methanolic leaf extract of Hedera nepalensis was evaluated for antiandrogenic and antispermatogenic activity in adult male rats through various reproductive parameters. Experimental findings showed significantly increased oxidative stress with reduced antioxidant activity at highest dose regimens in both in vitro and in vivo studies. Increased ROS generation and lipid peroxidation lead to DNA damage in rat sperm. In vivo determination of sperm parameters exhibited notable reduction in sperm motility, viability and DSP in dose-treated animals. Histopathological observations revealed reduced epithelial height and wider lumen having less number of spermatozoa in high-dose-treated groups. Additionally, a marked decline noted in Testosterone concentration in all extract treated groups, while plasma LH and FSH levels only in high-dose-treated groups were noted. The findings of the current study conclude that methanolic leaf extract of H. nepalensis has the potential to disturb male fertility by generating oxidative stress and hormonal imbalance leading to histological alterations and sperm DNA damage.

Abstract
AbstractBackgroundAcknowledging population control to be an essential step for global health promotes wide research study in the area of male contraception. Although there are a great number of synthetic contraceptives available in the market, they have plenty of adverse effects. Different potential strategies for male contraception were investigated over a long period time consisting of hormonal, chemical, and immunological interventions, although these methods showed good antifertility results with low failure rates relative to condoms.Main textThis review is based upon the concept of herbal contraceptives which are an effective method for controlling the fertility of animals and humans. This review has highlighted herbal medicinal plants and plant extracts which have been reported to possess significant antifertility action in males. The review considers those plants which are used traditionally for their spermicidal and antispermatogenic activities and imbalance essential hormones for fertility purposes and plants with reported animal studies as well as some with human studies for antifertility effect along with their doses, chemical constituents, and mechanism of action of the antifertility effect of the plants. This review also explains the phases of sperm formation, hormone production, and the mechanism of male contraceptives.ConclusionAs far as the relevance of the current review is discussed, it might be quite useful in generating monographs on plants and recommendations on their use. A lot of the plant species listed here might appear promising as effective alternative oral fertility-regulating agents in males. Therefore, significant research into the chemical and biological properties of such less-explored plants is still needed to determine their contraceptive efficacy and also to possibly define their toxic effects so that these ingredients can be utilized with confidence to regulate male fertility. The new inventions in this field are necessary to concentrate on modern, more potent drugs with less harmful content and that are self-administrable, less costly, and entirely reversible.

Abstract
This study evaluated the effects of subchronic exposure to Caryocar brasiliense peel ethanolic extract (CBPE) on reproductive function in male Swiss mice. CBPE was administered orally for 28 days at doses of 75, 150 and 300 mg.kg-1 bw; control group received saline. Fertility test was performed after 14 days of treatment and animals were euthanized after the end of the 28-day period for evaluation of the reproductive parameters. The tested doses produced no significant changes in plasma testosterone levels, daily sperm production, sperm concentration, sperm morphology or fertility rate. However, sperm transit time was reduced in the caput/corpus epididymis, the post-implantation loss rate increased and there were significant changes in spermatogenic dynamics at the highest dose. These results indicated that subchronic exposure to CBPE has low reproductive toxicity, but additional studies are recommended to provide evidence of long-term safety at high concentrations.

Abstract
Calcium (Ca2+) signaling is critical for successful fertilization. In spermatozoa, capacitation, hyperactivation of motility and the acrosome reaction are all mediated by increases in intracellular Ca2+ through CatSper (sperm-specific cation channel). The CatSper channel complex contains four pore-forming α subunits (CatSper1-4) and five accessory subunits called β, δ, ε, γ and ζ. Genetic deletion of any of the four CatSper genes in mice results in loss of hyperactivated motility and male infertility. Despite their vital role in male fertility, almost very little is known about influence of antifertility agents on CatSper gene expression in epididymis and epididymal spermatozoa. Therefore, we performed quantitative real-time qPCR analysis for CatSper expression in the epididymis and epididymal sperm of BALB/c mice after treatment with Dutasteride (DS), a dual 5-α reductase inhibitor and Nifedipine (NF) a calcium channel blocker as positive control. We observed that treatment with antifertility agents Dutasteride and Nifedipine induced significant decreases in the caput and cauda epididymal sperm counts, motility and fertility which could partly be attributed to alteration in the normal morphology of the sperm associated with downregulation/upregulation of CatSper mRNAs in epididymis and epididymal spermatozoa of male BALB/c mice. These can be explained on the basis of interference with mechanisms affecting calcium ion signaling resulting in changes in intracellular calcium required for sperm activity, finally affecting sperm maturation and fertility of male BALB/c mice. These studies provide some novel avenues for developing new male contraceptives in future.

Abstract
CONTEXT Terminalia chebula Retz (Combretaceae) and Musa balbisiana Colla (Musaceae) have a traditional reputation as a male contraceptive. OBJECTIVE To determine the hypo-testicular activity of aqueous extracts of Terminalia chebula (fruit) and Musa balbisiana (seed) separately, and in composite manner at the ratio of 1:1 named as 'Contracept-TM' compared to cyproterone acetate (CPA), for developing a polyherbal contraceptive. MATERIALS AND METHODS The separate extract of above said plants or 'Contracept-TM' at the dose of 40 mg/100 g body weight of rat/day or CPA at 2 mg/100 g body weight of rat/day was administered for 28 days. Spermiological, androgenic and oxidative stress sensors, LD50 and ED50/100 g body weight values were measured. RESULTS Treatment of individual, 'Contracept-TM' or CPA resulted significant decrease in the count of spermatogonia A (36.36-49.09%), pre-leptotene spermatocyte (19.11-55.30%), mid-pachytene spermatocyte (28.65-47.28%) and step 7 spermatid (29.65-51.59%). Activities of testicular Δ5, 3β (21.25-48.02%),17β-hydroxysteroid dehydrogenases (29.75-55.08%), catalase (19.06-43.29%) and peroxidase (30.76-62.82%), levels of testosterone (28.15-63.44%), testicular cholesterol (19.61-49.33%), conjugated diene (29.69-84.99%) and thiobarbituric acid reactive substances (41.25-86.73%) were elevated compare to the control. The ED50 and LD50 values were 40 mg and 5.8 g (T. chebula), 48 mg and 6.3 g (M. bulbisiana), 40 mg and 6.0 g ('Contracept-TM'), respectively. DISCUSSION AND CONCLUSION The said spermiological and androgenic sensors' levels were decreased significantly by 'Contracept-TM' than its constitutional individual plant extract and it may be comparable to standard anti-testicular drug like CPA. So, it may be concluded that above polyherbal formulation is potent for inducing hypo-testicular activity.

Abstract
Purpose Vitis vinifera is a species of Vitis that is native to the Mediterranean region, central Europe, and southwestern Asia, and has been used as a drug in traditional medicine. Traditional medicinal plants have been used for medical purposes with increasing effectiveness. It is important to identify drugs that inhibit spermatogenesis. Therefore, the present study aimed to investigate the effect of grape juice (GJ) on serum levels of inhibin B and sperm count in normal male rats. Materials and Methods Thirty-five adult male rats were randomly divided into five groups, each containing seven rats. Rats in the control group received 1 mL of normal saline over the course of the study. The experimental groups received GJ (100, 200, 400, and 1,600 mg/kg, orally, for 35 days consecutively). At the end of the treatment period, fertility indices were measured, including body weight difference, sex organ weight, sperm motility and count, epididymal sperm reserve, daily sperm production (DSP), and serum inhibin B levels. Results We found that GJ reduces body weight difference, was associated with decreased sperm motility and count in all treatment groups (p≤0.05 and p≤0.001, respectively). Moreover, DSP was significantly decreased in all treatment groups compared to the control group (p≤0.05), except in the group receiving 100 mg/kg of GJ. Inhibin B levels were significantly decreased in all treatment groups (p≤0.05). Conclusions The results of our study suggest that GJ in all doses, but especially in higher doses, may decrease fertility in male rats.

Abstract
CONTEXT Asparagus adscendens Roxb (Liliaceae) has a promising role in modulation of various disorders such as leucorrhea, diarrhea, dysentery, diabetes, senile pruritus, asthma, fatigue antifilarial, antifungal, spermatorrhea, and sexual debility/seminal weakness. OBJECTIVE To investigate dose-dependent effects of Asparagus adscendens root (AARR) extract on anabolic, reproductive, and sexual behavioral activities with a view to emphasize the pharmacological basis. MATERIALS AND METHODS Rats were divided into five groups: Group I (control), Groups II-IV (AARR treated, 100, 200, and 300 mg/kg body weight, respectively, orally for 30 d) and Group V (standard control treated with sildenafil citrate, 5 mg/kg body weight). On day 31, copulatory and potency tests were carried out and an autopsy was done to study the reproductive function, namely, organ weights, spermatogenesis, daily sperm production rate (DSP), and epididymal sperm counts (ESC). RESULTS AARR extract (200 and 300 mg/kg doses) caused a significant increase in body (p < 0.02 and p < 0.001) and testes (p < 0.01 and p < 0.001, control versus treated) weights. Reproductive activity showed significant a increase in testicular tubular diameter (p < 0.005-0.001), the number of round/elongated spermatids (p < 0.02-0.001), DSP, and ESC (p < 0.05-0.001). The sexual behavioral parameters including mounting/intromission frequency (13.0 ± 0.32/11.8 ± 0.37 and 18.2 ± 2.12/14.8 ± 1.15 versus 11.2 ± 0.66/8.2 ± 1.16), ejaculation latency (187.4 ± 1.91 and 191.4 ± 1.72 versus 180.0 ± 3.47), and penile erections (13.5 ± 0.3 and 14.5 ± 0.5 versus 8.5 ± 0.2) showed a significant increase at 200 and 300 mg/kg doses (ED50 300 mg/kg), but less than a standard control. In contrast, 100 mg/kg dose caused an increase (p < 0.005) in mounting latency only. CONCLUSION These results indicate increased anabolic, reproductive, and sexual activities by AARR treatment. Thus, the data provide scientific rationale for its traditional use as an aphrodisiac or for sexual disorders.

Abstract
Male contraceptive development in the present scenario is most viable aspect of research due to uncontrolled population growth in the world. In this respect investigators are busy to find out a safe male contraceptive drug. Researchers have started their finding for a suitable drug from natural sources because these are safe and easily acceptable for common man, most of natural sources are plants and their products. In this review 137 plants and their effects on reproduction and reproductive physiology are summarized. Some of them have intense effect on male reproductive system and do not produce any side effects. Reproductive toxicological studies are also important aspects of these kinds of researches, so it is important that drugs are safe and widely acceptable. An ideal male contraceptive can influence semen, testes, hormone level, accessory reproductive organs and general physiology of animals and produced some alterations. Many plants in this review are showing antifertility as well as antispermatogenic effects, so these may be used for further study for contraceptives development but it is important to find out the mechanism of reaction and further laboratory and clinical research on some plants are needed for final male contraceptive drug development. In conclusion this review will help for finding suitable plant products for male contraceptive clinical and laboratory studies.

The role of Allium cepa on aluminum-induced reproductive dysfunction in experimental male rat models. J Hum Reprod Sci 2012; 5:200-5. [PMID: 23162360 PMCID: PMC3493836 DOI: 10.4103/0974-1208.101022] [Citation(s) in RCA: 33] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2012] [Revised: 04/30/2012] [Accepted: 06/23/2012] [Indexed: 11/04/2022] Open
Abstract
AIM Reproductive toxicity is a major challenge associated with aluminum (Al) exposure. Studies that associated Al with reproductive dysfunction did not account for the possible influence of Allium cepa extract. This study, therefore, investigates the influence of A. cepa on aluminum-induced reproductive dysfunction. MATERIALS AND METHODS SIX MALE RATS PER GROUP WERE ASSIGNED TO ONE OF THE FOLLOWING FOUR TREATMENT GROUPS: The control animals were on control diet. A. cepa-treated rats received 1 ml of the extract/100 g body weight (BW), Al-treated rats received 100 mg AlCl(3) /kg BW, and A.cepa+Al received 1 ml of the extract/100 g BW plus 100 mg AlCl(3) /kg BW. Rats were orally administered their respective doses. A. cepa treatment was for 8 weeks, while Al treatment was for the last 3 days of the experimental period. RESULTS Results obtained showed that Al significantly decreased (P < 0.05) plasma testosterone, follicular stimulating hormone (FSH), luteinizing hormone (LH), sperm count, motility, morphology and viability, superoxide dismutase (SOD) and catalase (CAT) activities, while lipid peroxidation index [malondialdehyde (MDA)] was significantly (P < 0.05) increased. Reproductive hormones (except testosterone), sperm qualities, and enzymatic antioxidants were significantly (P < 0.05) increased in A. cepa-treated rats and A. cepa plus Al-treated rats, while MDA was significantly (P < 0.05) improved. Weights of testes were comparable in all groups. CONCLUSION It is thus suggested that Al exerts reproductive dysfunction by oxidative damage. A. cepa antagonizes the toxic effects of AlCl(3) and improves the antioxidant status and sperm quality of male rat. However, testosterone level did not increase with A. cepa treatment.

Abstract
This study was carried out to investigate the anti-fertility and anti-venom activities of the extract of the stem bark of Butea monosperma by inhibiting hyaluronidase, which is a spreading factor and plays a role in fertilisation. Among ethanol, methanol and water extracts, the ethanol extract dose-dependently inhibited the ovine, mouse testicular and Vipera russelli snake venom hyaluronidase enzyme activities, with IC₅₀ values 12.00 ± 0.45, 49.40 ± 1.58 µg and 125.42 ± 2.82 µg mL⁻¹, respectively. In a zymogram assay, the extract showed differential inhibition towards hyaluronidase isoform preferentially with low-molecular weight isoforms. The V. russelli snake venom-induced hemorrhage was significantly reduced at 1:05 ratio of venom-to-extract in mouse. The high antioxidant activity and total phenolic content in the ethanolic extract strongly correlated with the hyaluronidase inhibition. The above results justify the traditional use of the stem bark of B. monosperma as a contraceptive and a strong antidote to snake venom.

Abstract
To control growing world population, there is a need for male contraceptive methods that are comparable to female contraceptives, but due to lack of knowledge or investigation, no sufficient safe and effective contraceptives were developed till now. In the present investigation, the effect of 100% methanol extract of Opuntia dillenii phylloclade on reproduction in male rats was studied. A first group (I) received vehicle alone to serve as control. The second group (II) was further divided into treated and recovery groups, and the plant extract at 50 mg kg body weight(-1) was administered orally for 30 days. Biochemical, haematological and histopathological analyses were carried out to reveal the effects on reproductive organs in the male rats. The weights of reproductive organs were recorded. It was found that the number of fertile males, number of inseminated females, number of litters delivered and testosterone levels were reduced significantly. Epididymal sperm count and motility were also significantly decreased. Biochemical parameters support the antifertility activity of O. dillenii i.e. decreases in protein, glycogen content and elevation in cholesterol level. Testes and sperm morphology were altered significantly. Haematological parameters have not shown any significant changes. It is concluded that 100% methanol extract of O. dillenii possesses antifertility effects on male reproduction without change in general physiology.
