Antidepressant- and anxiolytic-like actions of Cajanus cajan seed extract mediated through monoaminergic, nitric oxide-cyclic GMP and GABAergic pathways. JOURNAL OF ETHNOPHARMACOLOGY 2023; 306:116142. [PMID: 36638856 DOI: 10.1016/j.jep.2023.116142] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Revised: 12/31/2022] [Accepted: 01/01/2023] [Indexed: 06/17/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The seeds of Cajanus cajan (L) Millsp, are used in Traditional medicine for the treatment of anxiety and other neurological disorders. Hence, this study is designed to investigate the antidepressant- and anxiolytic-like properties of ethanol seed extract of Cajanus cajan (CC) in mice. MATERIALS AND METHODS CC (50, 100 or 200 mg/kg, p.o.) was administered 1h before subjecting the animals to different behavioral models: forced swim test (FST) and tail suspension test (TST) (depressive-like behaviour), open field test (OFT), elevated plus maze (EPM), light-dark test (LDT) and hole-board test (HBT) for anxiety-like behaviour. To ascertain the pharmacodynamic of CC mice were pretreated with monoaminergic, nitrergic and GABAergic receptors antagonists. As well as molecular docking analysis of about 19 flavonoids present in CC on GABAA, α2 adrenoceptors and 5-HT2A receptors. RESULTS CC (50, 100 or 200 mg/kg, p.o.) treatment significantly reduced immobile time in both FST and TST when compared with vehicle-treated control. However, the pretreatment of mice with prazosin/yohimbine (α1/2 adrenoceptor antagonists, respectively), WAY100635 (5-HT1A receptor antagonist), ketanserin (5-HT2A receptor antagonist), sulpiride (dopamine D2 receptor antagonist), L-NG-Nitro arginine methyl ester (L-NAME), or methylene blue reversed the antidepressant-like effect of CC. In anxiety model, CC produced significant (p < 0.05) increase in open arms exploration and head dipping behavior which was reversed by flumazenil (benzodiazepine receptor antagonist) in the EPM. Docking analysis showed significant binding affinity of orientin, vitexin, pinostrobin and quercetin with 5HT2A, α2-adrenoceptor and GABAA receptors. CONCLUSION Findings from this study showed that C.cajan seeds extract exerts antidepressant-like effect through participation of monoaminergic systems (5-HT2 receptor, α1/α2-adrenoceptors, and dopamine D2-receptors), nitric oxide-cyclic GMP pathway and anxiolytic-like effect via GABAA benzodiazepine receptors. Moreso, presence of flavonoids with significant binding energies with monoaminergic and GABAergic systems support the potential of the extract in the management of mixed anxiety-depressive illness.

Abstract
Parkinson's disease (PD) is a neurodegenerative disorder characterized by both motor and non-motor features. The current treatment regimen for PD are dopamine enhancers which have been reported to worsen the disease prognosis after long term treatment, thus, the need for better treatment options. This study sought to investigate the protective action of Double Stem Cell® (DSC), a blend of stem cells extracts from Swiss apples (Malus Domestica) and Burgundy grapes (Vitis vinifera) on 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced Parkinsonism in mice and genetic model of PD in Drosophila melanogaster. Male albino mice were pretreated with MPTP (4 × 20 mg/kg, i.p., two hourly in 8 h), twelve hours before administration of DSC (8, 40, or 200 mg/kg, p.o.). Thereafter, behavioural, biochemical and immunohistochemical assays were carried out. The impact of vehicle or DSC supplementation on α-synuclein aggregation was evaluated in Drosophila melanogaster using the UAS-Gal4 system, female DDC-Gal4 flies were crossed with male UAS-α-synuclein, the progenies were examined for fecundity, locomotion, memory, and lifespan. MPTP-induced motor deficits in open field test (OFT), working memory impairment (Y-maze test (YMT)) and muscle incoordination (rotarod test) were ameliorated by DSC (8, 40 or 200 mg/kg) through dose-dependent and significant improvements in motor, cognitive and motor coordination. Moreso, MPTP exposure caused significant increase in lipid peroxidation and decrease in antioxidant enzymes activities (glutathione, catalase and superoxide dismutase) in the midbrain which were attenuated by DSC. MPTP-induced expression of microglia (iba-1), astrocytes (glia fibrillary acidic protein; GFAP) as well as degeneration of dopamine neurons (tyrosine hydroxylase positive neurons) in the substantia nigra (SN) were reversed by DSC. Supplementation of flies feed with graded concentration of DSC (0.8, 4 or 20 mg/ml) did not affect fecundity but improved climbing activity and lifespan. Findings from this study showed that Double Stem Cell improved motor and cognitive functions in both mice and Drosophila through attenuation of neurotoxin-induced oxidative stress and neuroinflammation.

Monoaminergic system involvement in the antidepressant-like and anxiolytic-like properties of novel β-dihydroagarofuran sesquiterpene alkaloid and triterpenes isolated from Gymnosporia heterophylla aerial parts in mice. Neurochem Int 2022; 158:105379. [PMID: 35724873 DOI: 10.1016/j.neuint.2022.105379] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Revised: 06/04/2022] [Accepted: 06/14/2022] [Indexed: 11/22/2022]
Abstract
Gymnosporia heterophylla (synonym Maytenus) is widely used in folk medicine for the treatment of various illness including neurological diseases. This study presents the antidepressant-like and anxiolytic-like effects of novel bioactive constituents; 3,4-seco-1-hydroxy-21-oxoolean-3,11-olide (A2), 1β,2β-diacetoxy-9β-benzoyloxy-6α-nicotinoyloxy-β-dihydroagarofuran (A5) as well as known 3-acetoxy-1β-hydroxyLupe-20(29)-ene (selective COX-2; A4) from the aerial parts of G. heterophylla. The antidepressant-like effect was studied using the forced swim test (FST) while the elevated plus maze test (EPMT) and open field test (OFT) were employed for anxiolytic-like effect. Acute treatment with A4 and A5 (0.5, 5 or 10 mg/kg) significantly reduced the duration of immobility and immobile episodes with prolongation of immobility latency in the FST with peak effects observed at 10 and 0.5 mg/kg, respectively. Moreover, antidepressant-like effect of A4 and A5 were relatively better than that of fluoxetine. Conversely, the pretreatment of mice with prazosin (1 mg/kg, α1-adrenoceptor antagonist), yohimbine (1 mg/kg; α2-adrenoceptor antagonist), or sulpiride (50 mg/kg; dopamine D2-receptor antagonist) reversed antidepressant-like effect of A4 and A5 but not WAY 100635 (10 mg/kg, i.p., selective 5-HT1A receptor antagonist), GR 127935 (5 mg/kg, i.p., selective 5-HT1B receptor antagonist), metergoline (4 mg/kg, i.p, non-selective 5-HT2 receptor antagonist), ketanserin (5 mg/kg, i.p., a selective 5-HT2A receptor antagonist) or p-chlorophenylalanine (pCPA) (100 mg/kg, i.p., tryptophan hydroxylase inhibitor) in the FST. Interestingly, A2, A4 and A5 significantly increased the time spent in the open arms of the EPM suggestive of anxiolytic-like action. Findings from this study showed that the novel β-dihydroagarofuran sesquiterpene alkaloid and triterpenes possesses antidepressant-like and anxiolytic-like effects through enhancement of monoaminergic signaling.

Ecdysteroids from the Stem Bark of Vitex doniana Sweet (Lamiaceae; ex. Verbenaceae): A Geographically Variable African Medicinal Species. Antibiotics (Basel) 2021; 10:antibiotics10080937. [PMID: 34438987 PMCID: PMC8388959 DOI: 10.3390/antibiotics10080937] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 07/27/2021] [Accepted: 08/02/2021] [Indexed: 11/21/2022] Open
Abstract
Vitex doniana Sweet is an African medicinal species that is prescribed as an aqueous bark extract to be applied topically or orally to achieve anti-infective outcomes. In select regions it is also taken orally as an antimalarial agent. The aim of the current study was to explore the biological properties of V. doniana and isolated compounds in the context of pathogenic bacteria and the protozoan parasite Plasmodium falciparum. Three compounds were isolated and assigned by nuclear magnetic resonance spectroscopy as ecdysteroids: (1) 20-hydroxyecdysone, (2) turkesterone, and (3) ajugasterone C. Interestingly, two of these compounds had not previously been identified in V. doniana, providing evidence of chemical variability between regions. The bark extract and three ecdysteroids were screened for activity against a panel of pathogenic bacteria associated with skin, stomach and urinary tract infections, and the protozoan parasite P. falciparum. The crude extract of the bark inhibited all bacterial strains with MIC values of 125–250 μg.mL−1. The three isolated compounds demonstrated less activity with MIC values of 500–1000 μg.mL−1. Furthermore, no activity was observed against P. falciparum at the screening concentration of 4.8 μg.mL−1. Nevertheless, we present a hypothesis for the possible mechanism for symptomatic relief of malarial fever, which may involve reduction of prostaglandin E(1) & E(2) activity in the hypothalamus via modulation of the monoaminergic system. While further studies are required to identify all antimicrobial agents within this plant species and to determine the cytotoxicity of each of these compounds, these data suggest that the traditional application of this species as an antiseptic is valid.

Abstract
OBJECTIVE: Asparagus adscendens Roxb. (Liliaceae), a traditional herbal medicine, has been used as an aphrodisiac and brain tonic in Asian countries. The aim of the present study is to investigate the antidepressant-like effect of standardized hydroethanolic extract of A. adscendens root and its possible mechanisms. MATERIALS AND METHODS: Mice administered with vehicle, imipramine (15 mg/kg/day; i.p.), and A. adscendens extract (AAE) (25, 50, and 100 mg/kg/day; i.p.) for 14 days were subjected to behavioral tests including forced swimming test (FST), tail suspension test (TST), and open-field test (OFT) on the 14th day. In order to explore the underlying mechanism behind an antidepressant effect of AAE, the brain monoamine levels, oxidative stress parameters, and serum corticosterone levels were monitored. RESULTS: Our results indicated that pretreatment of AAE (25, 50, and 100 mg/kg) for 14 days statistically significantly (P < 0.01) demonstrated antidepressant-like effect as evidenced by reduced immobility time in both FST (105, 78.6, and 53.6 s) and TST (97.6, 73.5, and 54.67 s), with no significant change in spontaneous locomotor activities as observed in OFT. Further, the behavioral improvement was supported by the statistically significantly (P < 0.05) enhanced levels of monoamines and reduced corticosterone level along with amelioration of oxidative stress in AAE-treated animals as compared to vehicle control group. Conclusion: Our findings clearly demonstrated the antidepressant-like effect of AAE, which might have been mediated through the modulation of monoaminergic system and by regulating hypothalamic–pituitary–adrenal axis with amelioration of oxidative stress.

Abstract
Ecdysteroids are secondary metabolites, widely distributed in the animal and plant kingdoms. They have a wide range of pharmacological effects in vertebrates, including mammals, most of which are beneficial for humans. Therefore, they have become compounds of interest for the pharmaceutical industry due to their adaptogenic, anabolic, hypoglycaemic, hypocholesterolaemic and antimicrobial activities, which are still being researched. Nowadays, ecdysteroids are present as active ingredients in bodybuilding supplements. Because of their complex structures, their chemical synthesis seems unprofitable and impractical. Due to high content of ecdysteroids in many plants, they are primarily obtained by extraction of the plant material. Plant in vitro cultures provide an alternative source of these compounds, helping to avoid problems associated with field production-such as variable yield or dependence on environmental factors, as well as limited availability of natural resources. Plant cell and tissue cultures may be suggested as alternatives for the production of plant biomass rich in pharmaceutically active ecdysteroids. Moreover, the use of common biotechnological strategies, such as elicitation or precursor feeding, may further increase the yield and improve production of these compounds. In this paper, we describe general information about ecdysteroids: their structure, biosynthesis, distribution, role in plants, and we review recent studies on micropropagation of ecdysteroid-producing plants and cell cultures, and potential ability of ecdysteroids enhancement in in vitro cultures.

Abstract
Depression is a serious global illness, becoming more and more common in developed countries. Because of specific symptoms it is considered as a leading cause of disability all over the world with a high death factor due to suicides. There are many antidepressants used in the therapy, but still more than 30% of patients do not respond to the treatment. The heterogeneous nature of the illness and its complex, unclear aetiology may be responsible for these difficulties. Next to the main monoaminergic hypothesis of depression there are also many other approaches connected with the pathophysiology of the disease, including hypothalamic-pituitary-adrenal axis dysregulation, dopaminergic, cholinergic, glutamatergic or GABA-ergic neurotransmission. Nevertheless, it can be unambiguously stated that serotonergic, noradrenergic and dopaminergic systems are precisely connected with pathogenesis of depression, and should be therefore considered as valuable targets in patients' treatment. Bearing that in mind, this review presents the role of serotonergic, adrenergic and dopaminergic receptors in antidepressant-like effect.
