Metastasized lung and liver cancers cause over 2 million deaths annually, and are amongst the top killer cancers worldwide. Morinda citrifolia (Noni) leaves are traditionally consumed as vegetables in the tropics. The macro and micro effects of M. citrifolia (Noni) leaves on metastasized lung cancer development in vitro and in vivo were compared with the FDA-approved anti-cancer drug Erlotinib. The extract inhibited the proliferation and induced apoptosis in A549 cells (IC50 = 23.47 μg/mL) and mouse Lewis (LL2) lung carcinoma cells (IC50 = 5.50 μg/mL) in vitro, arrested cancer cell cycle at G0/G1 phases and significantly increased caspase-3/-8 without changing caspase-9 levels. The extract showed no toxicity on normal MRC5 lung cells. Non-small-cell lung cancer (NSCLC) A549-induced BALB/c mice were fed with 150 and 300 mg/kg M. citrifolia leaf extract and compared with Erlotinib (50 mg/kg body weight) for 21 days. It significantly increased the pro-apoptotic TRP53 genes, downregulated the pro-tumourigenesis genes (BIRC5, JAK2/STAT3/STAT5A) in the mice tumours, significantly increased the anti-inflammatory IL4, IL10 and NR3C1 expression in the metastasized lung and hepatic cancer tissues and enhanced the NFE2L2-dependent antioxidant responses against oxidative injuries. The extract elevated serum neutrophils and reduced the red blood cells, haemoglobin, corpuscular volume and cell haemoglobin concentration in the lung cancer-induced mammal. It suppressed inflammation and oedema, and upregulated the endogenous antioxidant responses and apoptotic genes to suppress the cancer. The 300 mg/kg extract was more effective than the 50 mg/kg Erlotinib for most of the parameters measured.

Fulltext Noni (Morinda citrifolia L.) fruit extract attenuates the rewarding effect of heroin in conditioned place preference but not withdrawal in rodents

Narasingam M, Pandy V, Mohamed Z

Exp Anim, 2016 May 20;65(2):157-64.
PMID: 26744024 DOI: 10.1538/expanim.15-0088

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.

PMID: 31353737 DOI: 10.1111/jfbc.12868

The anti-leukemia mechanisms of Morinda citrifolia L. leaf extract were investigated on human Jurkat leukemia cells and in leukemia-induced BALB/c mice. The leukemia-induced mice were fed daily with the extract (100 or 200 mg/kg BW) and compared to ATRA (All-trans-retinoic-acid; 5 mg/kg BW). After 4 weeks' treatment, the extract (standardized to epicatechin and scopoletin), arrested Jurkat cell-cycle at the G0/G1 phase and activated the caspase-3 and caspase-8 (death-receptor extrinsic pathways). The extract dose-dependently reduced the blood and bone marrow myeloblasts levels of leukemia-induced mice; upregulated cancer suppressor genes CSF3, SOCS1, PTEN and TRP53; increased anti-inflammatory IL10 and IL4; downregulated anti-apoptotic or proliferation genes; decreased the pro-inflammatory NF-κβ; suppressed pro-angiogenesis VEGFA mRNA expressions, and restored the homeostatic immune or leukocytes levels. The extract directly ameliorated leukemia via cancer cells apoptosis, suppressed inflammation and angiogenesis; and mitigated bone marrow myeloblasts imbalance, without any observable toxicity on the animals. PRACTICAL APPLICATIONS: The scopoletin (coumarin) and epicatechin (flavonoid)-rich Morinda citrifolia (Noni) leaves may be used as functional food ingredient, vegetables, or dietary supplements to treat and suppress leukemia progression by directly killing the cancer cells and preventing new cancer cells development and bone marrow myeloblast imbalance in the bone marrow, without being toxic to normal cells. The M. citrifolia leaf extract suppressed inflammation, and potential metastasis by inhibiting new cancer-related blood vessel formation.

The antibacterial activity of solvent-extracted oil of noni (Morinda citrifolia L.), spinach (Spinacia oleracea L.), lady’s finger (Abelmoschus esculentus (L.) Moench), bitter gourd (Momordica charantia Linn.), and mustard (Brassica nigra L.) seed oils, and coconut (Cocos nucifera L.) oil, palm (Elaeis guineensis L.) mesocarp in hydrolyzed and unhydrolyzed form were determined in order to explore their potential usage as antibacterial agent. The hydrolysis process that was catalyzed by immobilized lipase of Rhizomucor miehei (RMIM) showed highest hydrolytic activity with 1.0 ml of added water volume except bitter gourd seed oil and palm mesocarp oil which has maximum hydrolytic activity with added water volume of 5 ml and 2.5 ml respectively. Before hydrolysis, all oil samples did not show inhibition ring zones (IRZ) on any of the tested bacteria strains (Salmonella typhimurium, Listeria monocytogenes and Escherichia coli O157:H7). Hydrolyzed lady’s finger and bitter gourd seed oil showed IRZ on all tested bacteria strains; hydrolyzed mustard seed oil on S. typhimurium and L. monocytogenes; hydrolyzed spinach seed oil and coconut oil on L. monocytogenes; hydrolyzed noni seed oil and palm mesocarp oil did not exhibit IRZ on any of the tested bacteria strains. Most of the hydrolyzed oil exhibit an inhibition activity that was different from their respective dominant fatty acids except noni seed oil and palm mesocarp oil.

Introduction: An economical and alternative diabetic wound care product is needed to address the escalating cost of diabetic wound ulcer treatment in Indonesia. Morindac itrifolia or commonly called noni, is a medicinal plant, dietary supplement, and traditional wound care product. This leaves extract contains antioxidant, anti-inflammatory, immune-stimulant, and antimicrobial properties. Trigona honey which is currently used to treat the diabetic wound at Kitamura Wound Specialist Clinic, Pontianak, Indonesia is known for its anti-inflammatory, anti-microbial and anti-proliferative properties. This study aims to compare the effectiveness of Morinda citrifolia leaves extract and Trigona honey in diabetic wound healing. Methods: A quasi-experimental study (a randomized control trial design) was conductedin the clinicon two subjects with diabetic foot ulcers (DFU). Trigona honey and Morinda citrifolia leaves extract packing was done to the ulcer of controlled subject and treatment subject respectively as a primary dressing. DFU assessment was done every 2 days using the MUNGS assessment tool and a wound closure rate for- mula. Wound C&S was analysed using a bacterial count machine. Results: Morinda citrifolia leaves extract was able to promote wound contraction, improved MUNGS score (from 9 to 8), reduced bacteria count significantly (from
8.51 x 105 to 1.00 x 105), reduced the percentage of slough by 70% and increased granulating tissue by 60% after the first application. Whereas, Trigona honey extract showed no wound contraction but improved MUNGS score (from 11 to 7). However, bacteria count was maintained at the lowest level (1.00 x 105), reduce the percentage of slough by 10%, and only increased granulating tissues by 10% after the first application. Conclusion: Both products were able to promote diabetic wound healing but the Morinda citrifolia leaves extract was found to be more effective, thus concludes the potential use of Morinda citrifolia leaves extract in treating DFU.

Damnacanthal is a potent inducer of apoptosis with anticancer activity by stimulating p53 and p21 genes in MCF-7 breast cancer cells

Aziz MY, Omar AR, Subramani T, Yeap SK, Ho WY, Ismail NH, et al.

PMID: 24765160

Damnacanthal, an anthraquinone compound, is isolated from the roots of Morinda citrifolia L. (noni), which has been used for traditional therapy in several chronic diseases, including cancer. Although noni has long been consumed in Asian and Polynesian countries, the molecular mechanisms by which it exerts several benefits are starting to emerge. In the present study, the effect of damnacanthal on MCF-7 cell growth regulation was investigated. Treatment of MCF-7 cells with damnacanthal for 72 h indicated an antiproliferative activity. The MTT method confirmed that damnacanthal inhibited the growth of MCF-7 cells at the concentration of 8.2 μg/ml for 72 h. In addition, the drug was found to induce cell cycle arrest at the G1 checkpoint in MCF-7 cells by cell cycle analysis. Damnacanthal induced apoptosis, determined by Annexin V-fluorescein isothiocyanate/propidium iodide (PI) dual-labeling, acridine-orange/PI dyeing and caspase-7 expression. Furthermore, damnacanthal-mediated apoptosis involves the sustained activation of p21, leading to the transcription of p53 and the Bax gene. Overall, the present study provided significant evidence demonstrating that p53-mediated damnacanthal induced apoptosis through the activation of p21 and caspase-7.

Fulltext Antipsychotic-like activity of scopoletin and rutin against the positive symptoms of schizophrenia in mouse models

Pandy V, Vijeepallam K

Exp Anim, 2017 Oct 30;66(4):417-423.
PMID: 28701621 DOI: 10.1538/expanim.17-0050

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.

Shalan NA, Mustapha NM, Mohamed S

Nutrition, 2017 Jan;33:42-51.
PMID: 27908549 DOI: 10.1016/j.nut.2016.08.006

OBJECTIVE: Black tea and Nonileaf are among the dietary compounds that can benefit patients with bone resorption disorders. Their bone regeneration effects and their mechanisms were studied in estrogen-deficient rats.
METHODS: Noni leaves (three doses) and black tea water extracts were fed to ovariectomized rats for 4 mo, and their effects (analyzed via mechanical measurements, micro-computed tomography scan, and reverse transcriptase polymerase chain reaction mRNA) were compared with Remifemin (a commercial phytoestrogen product from black cohosh).
RESULTS: The water extracts (dose-dependently for noni leaves) increased bone regeneration biomarker (runt-related transcription factor 2, bone morphogenetic protein 2, osteoprotegerin, estrogen receptor 1 [ESR1], collagen type I alpha 1A) expressions and reduced the inflammatory biomarkers (interleukin-6, tumor necrosis factor-α, nuclear factor [NF]-κB, and receptor activator of NF-κB ligand) mRNA expressions/levels in the rats. The extracts also improved bone physical and mechanical properties. The extracts demonstrated bone regeneration through improving bone size and structure, bone mechanical properties (strength and flexibility), and bone mineralization and density.
CONCLUSIONS: The catechin-rich extract favored bone regeneration and suppressed bone resorption. The mechanisms involved enhancing osteoblast generation and survival, inhibiting osteoclast growth and activities, suppressing inflammation, improving bone collagen synthesis and upregulating ESR1 expression to augment phytoestrogenic effects. Estrogen deficiency bone loss and all extracts studied (best effect from Morinda leaf at 300 mg/kg body weight) mitigated the loss, indicating benefits for the aged and menopausal women.

Morinda elliptica Ridley (Rubiaceae) has been used traditionally as a medicine to treat various diseases in Malaysia and southeast Asia. In the present study we investigated the immunomodulatory effects of damnacanthal isolated from the roots of Morinda elliptica. The immunomodulatory effect of this compound was evaluated by using the lymphocyte proliferation assay with mouse thymocytes and human peripheral blood mononuclear cells (PBMC). In addition, the effect of the compound on PBMC cell cycle progression was studied by using flow cytometry. The production of human interleukin-2 and human inteleukin-12 cytokines was also assessed using the enzyme linked immunosorbent assay (ELISA) technique. The lymphocyte proliferation assay showed that damnacanthal was able to activate mouse thymocytes and PBMC at a low concentration (0.468 microg/mL). Moreover, the production of human interleukin-2 and human interleukin-12 cytokines in the culture supernatant from damnacanthal activated lymphocytes was markedly up-regulated at 24 h and sustained until 72 h with a slight decrease with time. A positive correlation was found between the level of these two cytokines and the MTT-based proliferation assay. Based on the above results, damnacanthal can act as an immunomodulatory agent which may be very useful for maintaining a healthy immune system.

PMID: 26798649 DOI: 10.1155/2016/2391592

The prevalence of obesity is increasing worldwide, with high fat diet (HFD) as one of the main contributing factors. Obesity increases the predisposition to other diseases such as diabetes through various metabolic pathways. Limited availability of antiobesity drugs and the popularity of complementary medicine have encouraged research in finding phytochemical strategies to this multifaceted disease. HFD induced obese Sprague-Dawley rats were treated with an extract of Morinda citrifolia L. leaves (MLE 60). After 9 weeks of treatment, positive effects were observed on adiposity, fecal fat content, plasma lipids, and insulin and leptin levels. The inducement of obesity and treatment with MLE 60 on metabolic alterations were then further elucidated using a (1)H NMR based metabolomics approach. Discriminating metabolites involved were products of various metabolic pathways, including glucose metabolism and TCA cycle (lactate, 2-oxoglutarate, citrate, succinate, pyruvate, and acetate), amino acid metabolism (alanine, 2-hydroxybutyrate), choline metabolism (betaine), creatinine metabolism (creatinine), and gut microbiome metabolism (hippurate, phenylacetylglycine, dimethylamine, and trigonelline). Treatment with MLE 60 resulted in significant improvement in the metabolic perturbations caused obesity as demonstrated by the proximity of the treated group to the normal group in the OPLS-DA score plot and the change in trajectory movement of the diseased group towards the healthy group upon treatment.

Morinda citrifolia L. is a plant of the family Rubiaceae and is known as Indian mulberry or Noni in India. It is a perennial herb native to Southeast Asia and has been used over the years as a food supplement and medicinal plant. Noni fruits are reported to possess anticancer, fungicidal, antiviral and antiarthritic effects. The objective of our study is the screening of the immunomodulatory activity of the total extract, fractions, and isolated compounds of Noni fruits to identify their bioactive compounds. To achieve our goal, an ethanol extract (EE) was prepared from Noni fruits. Fractionation and purification of the EE were accomplished. The cell-mediated immune (CMI) response in prednisolone-induced immunosuppression rats was evaluated. The toxicity of the EE, fractions and isolated compounds on the differentiated THP-1 macrophage was assessed using the MTT viability assay. Moreover, the inflammation-related immune responses in lipopolysaccharide (LPS)-induced THP-1 macrophage activation were evaluated. Fractionation of the EE gave three fractions, dichloromethane (DCMF), water (WF) and methanol (MF). Purification of DCMF yielded stigmast-7-ene-3-ol (M1), 28-hydroxy-3β-acetoxy-9-dehydrogramisterol (M2), 3β-acetoxy-taraxast-20(30)-ene-21-ol (M3), 22-dehydroclerosterol (M4) and 22-dehydroclerosterol-3-O-β-d-glucopyranoside (M5), while purification of MF yielded quercetin (M6), hesperidin (M7), naringin (M9) and gallic acid (M8). The results revealed that DCMF elicited an increase in paw edema to the extent of 35.8%. All the tested samples had no cytotoxic effect on THP-1 macrophages. Co-treatment of the LPS-induced macrophages with DCMF, M2, M3, and M6 decreased the production of TNF-α, IL-1β, and IL-6/IL-10. The expression of iNOS, COX-2, and NF-κB decreased to 0.14 ± 0.02, 0.15 ± 0.02, and 0.17 ± 0.03, respectively, after co-treatment with LPS and DCMF. M2 attenuated the expression of iNOS and NF-κB to 0.18 ± 0.03 and 0.17 ± 0.03, respectively. Additionally, M3 attenuated the expression of iNOS to 0.18 ± 0.03, and after co-treatment with M6 and LPS, the expression of COX-2 and NF-κB was down-regulated to 0.2 ± 0.03. Our study proves the immunomodulatory effect of Noni fruits and specifies for the first time the compounds responsible for their activity.
