Nukitram J, Kumarnsit E, Cheaha D. A 1:1 ratio of cannabidiol: tetrahydrocannabinol attenuates methamphetamine conditioned place preference in mice: A prospective study of antidopaminergic mechanism. Brain Res Bull 2023; 192:47-55. [PMID: 36336144 DOI: 10.1016/j.brainresbull.2022.11.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 10/30/2022] [Accepted: 11/02/2022] [Indexed: 11/05/2022]
Abstract
A 1:1 ratio of cannabidiol to tetrahydrocannabinol (CT) was suggested to be safer for therapeutic purposes in many illnesses. However, CT effects on methamphetamine (METH) conditioned place preference (CPP) remained largely unexplored. This study aimed to examine the effects of CT on METH CPP mice evaluated by animal behaviors accompanied by local field potential (LFP) signals analysis. Male ICR mice were implanted with the LFP electrode in the ventral tegmental area (VTA) and the nucleus accumbens (NAc). Animals were next subjected to induce METH CPP by peritoneal injection with 1 mg/kg METH and 0.9 % NaCl on an alternate day for ten sessions and confined to the corresponding compartment for 30 min meanwhile control mice were given normal saline all day for both compartments. On testing day, either 10 mg/kg CT or 20 mg/kg bupropion (BP), a dopamine reuptake inhibitor, and VTA GABAergic suppressor were orally administered before CPP testing. The results revealed that CPP scores elevation was observed in the METH+vehicle and METH+BP mice, but this was reversed by CT treatment. Although both METH+vehicle and METH+BP enhanced the VTA delta power, NAc gamma I power, NAc delta-gamma coupling, and VTA-NAc gamma I coherence, changes in opposite trends of all mentioned parameters were seen by CT application. These improvements were postulated to involve the antidopaminergic effects of CT via modulations of neural signaling in the VTA and NAc. Altogether, the evidence-based study may suggest the use of CT as alternative drug for METH-seeking and craving therapy.

Abstract
Noni fruits (Morinda citrifolia) are a source of phenolic bioactive compounds (scopoletin, alizarin, and rutin), which have antioxidant, antimicrobial, anticancer, and anti-inflammatory activities. In this study, subcritical water was applied to determine the extraction yields and kinetics of phenolic compounds from noni fruits. The scopoletin and alizarin yields increased with the increase in temperature from 100 to 140 °C, while that of rutin increased up to 120 °C and then decreased at 140 °C. The yields of all the compounds rapidly increased from 1 to 2 mL/min and then slightly up to 3 mL/min of water flow rate. The extraction kinetics were assessed using two mathematical models. The two-site kinetic desorption model had a better fit for all experimental conditions throughout the extraction cycle and best described the extraction kinetics of phenolic compounds from noni fruits. The diffusion coefficients of scopoletin and alizarin at 140 °C and 3 mL/min were 3.7- and 16.2-fold higher than those at 100 °C and 1 mL/min, respectively. The activation energies of alizarin were 2.9- to 8.5-fold higher than those of scopoletin at various flow rates. Thus, subcritical water could be an excellent solvent with higher extraction yields and shorter extraction times using an environmentally friendly solvent.

Abstract
OBJECTIVES Scopoletin (6-methoxy-7-hydroxycoumarin) is a naturally occurring coumarin belonging to the category of secondary metabolites. Coumarins are commonly found in several herbs and play a prominent role in the defense mechanism of plants. Beneficial effects of scopoletin including antioxidant, anti-diabetic, hepatoprotective, neuroprotective and anti-microbial activity induced via numerous intracellular signalling mechanisms have been widely studied. However, anti-inflammation and anti-tumorigenesis properties of scopoletin are not well documented in the literature. Therefore, the primary focus of the present review was to highlight the plethora of research pertaining to the signalling mechanisms associated with the prevention of the progression of disease condition by scopoletin. KEY FINDINGS Multiple signalling pathways like nuclear erythroid factor-2 (NEF2)-related factor-2 (NRF-2), apoptosis/p53 signalling, nuclear factor-κB (NF-κB) signalling, autophagy signalling, hypoxia signalling, signal transducer and activator of transcription-3 (STAT3) signalling, Wnt-β signalling, Notch signalling are coupled with the anti-inflammation and anti-tumorigenesis potential of scopoletin. SUMMARY Understanding crucial targets in these molecular signalling pathways may support the role of scopoletin as a promising naturally derived bioactive compound for the treatment of several diseases.

Abstract
Silphion was an ancient medicinal gum-resin; most likely obtained from a Ferula species growing in the Cyrene region of Libya ca. 2500 years ago. Due to its therapeutic properties and culinary value, silphion became the main economic commodity of the Cyrene region. It is generally believed that the source of silphion became extinct in the first century AD. However, there are a few references in the literature about the cultivated silphion plant and its existence up to the fifth century. Recently, a rare and endemic Ferula species that produces a pleasant-smelling gum-resin was found in three locations near formerly Greek villages in Anatolia. Morphologic features of this species closely resemble silphion, as it appears in the numismatic figures of antique Cyrenaic coins, and conform to descriptions by ancient authors. Initial chemical and pharmacological investigations of this species have confirmed the medicinal and spice-like quality of its gum-resin supporting a connection with the long-lost silphion. A preliminary conservation study has been initiated at the growth site of this rare endemic Ferula species. The results of this study and their implications on the regional extinction event, and future development of this species will be discussed.

Therapeutic Effects of Morinda citrifolia Linn. (Noni) Aqueous Fruit Extract on the Glucose and Lipid Metabolism in High-Fat/High-Fructose-Fed Swiss Mice. Nutrients 2020; 12:nu12113439.

Abstract
The aim of this study was to evaluate the therapeutic effects of two different doses (250 and 500 mg/kg) of Morinda citrifolia fruit aqueous extract (AE) in high-fat/high-fructose-fed Swiss mice. The food intake, body weight, serum biochemical, oral glucose tolerance test (OGTT), and enzyme-linked immunosorbent assay (ELISA), as well as histological analyses of the liver, pancreatic, and epididymal adipose tissue, were used to determine the biochemical and histological parameters. The chemical profile of the extract was determined by ultra-fast liquid chromatography–diode array detector–tandem mass spectrometry (UFLC–DAD–MS), and quantitative real-time PCR (qRT-PCR) was used to evaluate the gene expressions involved in the lipid and glucose metabolism, such as peroxisome proliferative-activated receptors-γ (PPAR-γ), -α (PPAR-α), fatty acid synthase (FAS), glucose-6-phosphatase (G6P), sterol regulatory binding protein-1c (SREBP-1c), carbohydrate-responsive element-binding protein (ChREBP), and fetuin-A. Seventeen compounds were tentatively identified, including iridoids, noniosides, and the flavonoid rutin. The higher dose of AE (AE 500 mg/kg) was demonstrated to improve the glucose tolerance; however, both doses did not have effects on the other metabolic and histological parameters. AE at 500 mg/kg downregulated the PPAR-γ, SREBP-1c, and fetuin-A mRNA in the liver and upregulated the PPAR-α mRNA in white adipose tissue, suggesting that the hypoglycemic effects could be associated with the expression of genes involved in de novo lipogenesis.

Abstract
The Keap1/Nrf2/ARE system is a central defensive mechanism against oxidative stress which plays a key role in the pathogenesis and progression of many diseases. Nrf2 is a redox-sensitive transcription factor controlling a variety of downstream antioxidant and cytodefensive genes. Nrf2 has a powerful anti-inflammatory activity mediated via modulating NF-κB. Therefore, pharmacological activation of Nrf2 is a promising therapeutic strategy for the treatment/prevention of several diseases that are underlined by both oxidative stress and inflammation. Coumarins are natural products with promising pharmacological activities, including antioxidant, anticancer, antimicrobial, and anti-inflammatory efficacies. Coumarins are found in many plants, fungi, and bacteria and have been widely used as complementary and alternative medicines. Some coumarins have shown an ability to activate Nrf2 signaling in different cells and animal models. The present review compiles the research findings of seventeen coumarin derivatives of plant origin (imperatorin, visnagin, urolithin B, urolithin A, scopoletin, esculin, esculetin, umbelliferone, fraxetin, fraxin, daphnetin, anomalin, wedelolactone, glycycoumarin, osthole, hydrangenol, and isoimperatorin) as antioxidant and anti-inflammatory agents, emphasizing the role of Nrf2 activation in their pharmacological activities. Additionally, molecular docking simulations were utilized to investigate the potential binding mode of these coumarins with Keap1 as a strategy to disrupt Keap1/Nrf2 protein-protein interaction and activate Nrf2 signaling.

Abstract
Morinda is a largest genus of Rubiaceae family, and its 11 species are found in India. In India, plant species are known by several common names as great morinda, Indian mulberry, noni, beach mulberry and cheese fruit. Various Morinda products (capsules, tablets, skin products and fruit juices) are available in the market, used by people for treatment of several health complaints. A diversity of phytochemicals including iridoids, flavonoids, flavonoid glycosides, anthraquinones, coumarins, lignanas, noniosides, phenolics and triterpenoids have been reported from Morinda species. Morinda species are used in the treatment of inflammation, cancer, diabetes, psyquiatric disorders, and bacterial and viral infections. The noni fruit juice (Morinda citrifolia) and its products are used clinically in the treatment of cancer, hypertension and cervical spondylosis affecting patients. M. citrifolia fuit juice, with different doses, is used in the maintaining blood pressure and reducing of superoxides, HDL and LDL levels. Similarly, oligosaccharide capsules and tablets of root extract of M. officinalis are recommended as medicine for the treatment of kidney problems and sexual dysfunctions of patients. The toxicological studies revealed that higher doses of fruit juice (4,000 or 5,000 mg/kg) of M. citrifolia for 2 or more months cause toxic effects on liver and kidneys. M. officinalis root extracts (ethanolic and aqueous) are found fully safe during treatment of diseases. A large number of reviews are available on M. citrifolia but very few studies are conducted on other Indian Morinda species. This review reports the comprehensive knowledge on state-wise distribution, botany, ethnomedicinal uses, phytochemistry, pharmacological activities, clinical applications and toxicological evaluations of 11 species of Morinda found in India.

Abstract
The objective of this study was to evaluate the effect of a botanical-based equine nutraceutical on contractility of gastric smooth muscle in vitro. Gastric ulcers are prevalent in performance horses and negatively impact horse welfare. Gastric hypermotility has been positively associated with the development of gastric ulceration in nonequine species, and reduction of hypermotility may be protective against their development. Stomachs from 12 pigs processed for food at a provincially inspected abattoir were collected within 1 hour of slaughter. Explants of nonglandular gastric tissue were prepared and suspended in a tissue bath, attached to a force transducer, in the presence or absence of a simulated digest extract of the nutraceutical. Tissue was stimulated to contract using increasing doses of acetylcholine. Peak and mean contractile force over 1 and 2 minutes after exposure to acetylcholine were measured. Exposure of gastric smooth muscle to the nutraceutical significantly reduced contractility of the tissue. These data provide support for the use of this nutraceutical to reduce contractility of nonglandular gastric smooth muscle and may indicate a protective effect of this nutraceutical in horses with mechanically induced gastric ulcers. Future studies are needed to clarify the role of gastric hypermotility on development of equine gastric ulcers and to determine the effect of this nutraceutical on equine gastric contractility and ulcerogenesis in vivo.

Abstract
Noni bagasse is usually wasted after the noni juice extraction process. The purpose of this study was to investigate the phytochemical composition of noni bagasse (with and without seeds) obtained after a 1 week period of a short-term juice drip-extraction process from over-ripe noni fruit. Totals of free phenolics, flavonoids, condensed tannins, carotenoids, and most of the minerals were higher in bagasse without seeds (NSB) than in bagasse with seeds (WSB), whereas bound phenolics and total and insoluble dietary fiber were higher in WSB than in NSB. β-Carotene and lutein, quantified by HPLC-DAD, were higher in both bagasse than in juice. A total of 16 phenolic compounds and 2 iridoids were determined by UPLC-DAD-ESI-MS. Among them, procyanidin B-type dimer, caffeoylquinic-acid-hexoside, and quercetin-hexose-deoxyhexose have not been previously reported in noni bagasse, noni juice, or noni fruit. Isorhamnetin-3- O-rutinoside was the most abundant compound in both bagasses. In conclusion, both bagasses are potential sources of phytochemical compounds for the food and pharmaceutical industries.

Abstract
Scopoletin is a bioactive component in many edible plants and fruits. This study investigated the effects of scopoletin on hepatic steatosis and inflammation in a high-fat diet fed type 1 diabetic mice by comparison with metformin. Scopoletin (0.01%, w/w) or metformin (0.5%, w/w) was provided with a high-fat diet to streptozotocin-induced diabetic mice for 11 weeks. Both scopoletin and metformin lowered blood glucose and HbA1c , serum ALT, TNF-α and IL-6 levels, glucose intolerance, and hepatic lipid accumulation compared with the diabetic control group. Scopoletin or metformin down-regulated hepatic gene expression of triglyceride (Pparg, Plpp2, and Dgat2) and cholesterol (Hmgcr) synthesis as well as inflammation (Tlr4, Myd88, Nfkb1, Tnfa, and Il6), while it up-regulated Cyp7a1 gene. Hepatic PPARγ and DGAT2 protein levels were also down-regulated in scopoletin or metformin group compared with the control group. Scopoletin or metformin also inhibited hepatic fatty acid synthase and phosphatidate phosphohydrolase activities. These results suggest that scopoletin protects against diabetes-induced steatosis and inflammation by inhibiting lipid biosynthesis and TLR4-MyD88 pathways. Copyright © 2017 John Wiley & Sons, Ltd.

Abstract
In an earlier report, we demonstrated an antipsychotic-like activity of a methanolic
extract of Morinda citrifolia Linn fruit in mouse models and postulated
the contribution of its bioactive principles, scopoletin and rutin. Moreover, the
antidopaminergic activities of scopoletin and rutin were reported in isolated vas deferens
preparations. In the present study, scopoletin and rutin were assessed for
antipsychotic-like activity using apomorphine-induced climbing behavior and
methamphetamine-induced stereotypy in mice. The results of this study revealed that
scopoletin and rutin (0.05, 0.1, 0.5, and 1 mg/kg, p.o.) had a “U-shaped” dose-dependent
effect on climbing and stereotyped behaviors induced by apomorphine and methamphetamine,
respectively, in mice. A significant reduction in climbing and stereotyped behaviors
caused by scopoletin and rutin was observed only at a dose 0.1 mg/kg. This study suggests
that scopoletin and rutin can alleviate positive symptoms of schizophrenia only at a
specific dose. Further studies evaluating the effects of scopoletin and rutin on animal
models for negative symptoms of schizophrenia are required for a novel drug discovery in
the treatment of neuropsychiatric diseases.

Abstract
Morinda citrifolia, also known as noni, is commonly used in popular medicine in Brazil. Many parts of the noni tree are utilized in such practices, including the roots, leaves and seeds. Through a search of online databases, the present article reviews 92 research studies on the biological actions of M. citrifolia. The paper will discuss the therapeutic effects of noni and its compounds in a variety of forms of presentation, focusing on studies that support its traditional use. A large and diverse number of properties were identified, which were divided into immunostimulatory, antitumor, antidiabetic, anti-obesity, antibacterial and anti-septic, antifungal, antiviral, leishmanicidal, antiinflammatory, antinociceptive and analgesic, antioxidant, neuroprotective, wound healing, antiallergic, antiangiogenic, antiemetic and anti-nausea, anti-gastric ulcer and oesophagitis, anthelmintic, antimutagenic, antipsychotic, anxiolytic, photoprotective, anti-wrinkle and periodontal tissue regeneration activities. While it was concluded that although M. citrifolia is widely and successfully used for the treatment or prevention of various diseases, it should be consumed carefully, and only after exhaustive studies into its chemical constituents and mechanisms of action, both in in vitro and in vivo models, as well as clinical trials.

Abstract
In earlier ex vivo studies, we reported the biphasic effect of a
methanolic extract of unripe Morinda citrifolia fruit (MMC) on
dopamine-induced contractility in isolated rat vas deferens preparations. The present
in vivo study was designed and undertaken to further explore our
earlier ex vivo findings. This study examined the effect of the ethyl
acetate fraction of a methanolic extract of unripe Morinda citrifolia
Linn. fruit (EA-MMC; 5–100 mg/kg, p.o.) on the dopaminergic system using mouse models of
apomorphine-induced climbing time and climbing behavior, methamphetamine-induced
stereotypy (sniffing, biting, gnawing, and licking) and haloperidol-induced catalepsy
using the bar test. Acute treatment with EA-MMC at a low dose (25 mg/kg, p.o.)
significantly attenuated the apomorphine-induced climbing time and climbing behavior in
mice. Similarly, EA-MMC (5 and 10 mg/kg, p.o.) significantly inhibited
methamphetamine-induced stereotyped behavior in mice. These results demonstrated that the
antidopaminergic effect of EA-MMC was observed at relatively lower doses (<25 mg/kg,
p.o.). On the other hand, EA-MMC showed dopaminergic agonistic activity at a high dose
(3,000 mg/kg, p.o.), which was evident from alleviation of haloperidol (a dopamine
D2 blocker)-induced catalepsy in mice. Therefore, it is concluded that EA-MMC
might possess a biphasic effect on the dopaminergic system, i.e., an antagonistic effect
at lower doses (<25 mg/kg, p.o.) and an agonistic effect at higher doses (>1,000
mg/kg, p.o.). However, further receptor-ligand binding assays are necessary to confirm the
biphasic effects of M. citrifolia fruit on the dopaminergic system.

Abstract
In this study, we investigated the antipsychotic-like effect of methanolic extract of Mitragyna speciosa leaf (MMS) using in vivo and ex vivo studies. In vivo studies comprised of apomorphine-induced climbing behavior, haloperidol-induced catalepsy, and ketamine-induced social withdrawal tests in mice whereas the ex vivo study was conducted utilizing isolated rat vas deferens preparation. Acute oral administration of MMS (50–500 mg/kg) showed an inverted bell-shaped dose-response in apomorphine-induced cage climbing behavior in mice. The effective inhibitory doses of MMS (75 and 100 mg/kg, p.o.) obtained from the apomorphine study was further tested on haloperidol (subcataleptic dose; 0.1 mg/kg, i.p.)-induced catalepsy in the mouse bar test. MMS (75 and 100 mg/kg, p.o.) significantly potentiated the haloperidol-induced catalepsy in mice. Interestingly, MMS at the same effective doses (75 and 100 mg/kg, p.o.) significantly facilitated the social interaction in ketamine-induced social withdrawal mice. Furthermore, MMS inhibited the dopamine-induced contractile response dose-dependently in the isolated rat vas deferens preparations. In conclusion, this investigation provides first evidence that MMS exhibits antipsychotic-like activity with potential to alleviate positive as well as negative symptoms of psychosis in mice. This study also suggests the antidopaminergic activity of MMS that could be responsible for alleviating positive symptoms of psychosis.

Abstract
Phytotherapy is an emerging field successfully utilized to treat various chronic diseases including alcohol dependence. In the present study, we examined the effect of the standardized methanolic extract of Morinda citrifolia Linn. unripe fruit (MMC), on compulsive ethanol-seeking behavior using the mouse conditioned place preference (CPP) test. CPP was established by injections of ethanol (2 g/kg, i.p.) in a 12-day conditioning schedule in mice. The effect of MMC and the reference drug, acamprosate (ACAM), on the reinforcing properties of ethanol in mice was studied by the oral administration of MMC (1, 3, and 5 g/kg) and ACAM (300 mg/kg) 60 min prior to the final CPP test postconditioning. Furthermore, CPPs weakened with repeated testing in the absence of ethanol over the next 12 days (extinction), during which the treatment groups received MMC (1, 3, and 5 g/kg, p.o.) or ACAM (300 mg/kg, p.o.). Finally, a priming injection of a low dose of ethanol (0.4 g/kg, i.p.) in the home cage (Reinstatement) was sufficient to reinstate CPPs, an effect that was challenged by the administration of MMC or ACAM. MMC (3 and 5 g/kg, p.o.) and ACAM (300 mg/kg, p.o.) significantly reversed the establishment of ethanol-induced CPPs and effectively facilitated the extinction of ethanol CPP. In light of these findings, it has been suggested that M. citrifolia unripe fruit could be utilized for novel drug development to combat alcohol dependence.

Abstract
The effect of ethanolic extract of Morinda citrifolia leaves and fruit on blood pressure in dexamethasone-induced hypertension rat was evaluated. Total phenolic content of Morinda citrifolia leaves ethanolic extract (MCLEE) and Morinda citrifolia leaves ethanolic extract (MCFEE) was 1.789 ± 0.116 and 1.677 ± 0.051 mg of gallic acid equivalents per gram sample, respectively. Rutin level in MCLEE was 0.92 ± 0.19%, and scopoletin level in MCFEE was 0.46 ± 0.05%. MCLEE, MCFEE, and its extract combination significantly decreased the blood pressure of hypertensive rats. The combination group showed highest hypotensive activity by lowering systolic blood pressure by 16.71 ± 3.95%, diastolic blood pressure by 21.49 ± 7.90%, and mean arterial blood pressure by 19.58% ± 6.35. All extract treatments have not been able to repair or inhibit renal damage caused by dexamethasone induction.

Abstract
The present study was designed to investigate the effect of a methanolic extract of
Morinda citrifolia Linn. fruit (MMC) on the rewarding effect of heroin
in the rat conditioned place preference (CPP) paradigm and naloxone-precipitated
withdrawal in mice. In the first experiment, following a baseline preference test
(preconditioning score), the rats were subjected to conditioning trials with five
counterbalanced escalating doses of heroin versus saline followed by a preference test
conducted under drug-free conditions (post-conditioning score) using the CPP test.
Meanwhile, in the second experiment, withdrawal jumping was precipitated by naloxone
administration after heroin dependence was induced by escalating doses for 6 days (3×/
day). The CPP test results revealed that acute administration of MMC (1, 3, and 5 g/kg
body weight (bw), p.o.), 1 h prior to the CPP test on the 12th day significantly reversed
the heroin-seeking behavior in a dose-dependent manner, which was similar to the results
observed with a reference drug, methadone (3 mg/kg bw, p.o.). On the other hand, MMC (0.5,
1, and 3 g/kg bw, p.o.) did not attenuate the heroin withdrawal jumps precipitated by
naloxone. These findings suggest that the mechanism by which MMC inhibits the rewarding
effect of heroin is distinct from naloxone-precipitated heroin withdrawal.

Abstract
Escalating trends of chronic diseases such as type-2 diabetes (T2D) have sparked a renewed interest in complementary and alternative medicine, including herbal products. Morinda citrifolia (noni) has been used for centuries by Pacific Islanders to treat various ailments. Commercial noni fruit juice has been marketed as a dietary supplement since 1996. In 2003, the European Commission approved Tahitian noni juice as a novel food by the Health and Consumer Protection Directorate General. Among noni's several health benefits, others and we have demonstrated the anti-diabetic effects of fermented noni fruit juice in animal models. Unfortunately, noni's exciting journey from Polynesian medicine to the research bench does not reach its final destination of successful clinical outcomes when translated into commercial products. Noni products are perceived to be safe due to their "natural" origin. However, inadequate evidence regarding bioactive compounds, molecular targets, mechanism of action, pharmacokinetics, long-term safety, effective dosages, and/or unanticipated side effects are major roadblocks to successful translation "from bench side to bedside". In this review we summarize the anti-diabetic potential of noni, differences between traditional and modern use of noni, along with beneficial clinical studies of noni products and challenges in clinical translation of noni's health benefits.
