Abstract
Unmet medical needs in treating critical-size bone defects have led to the development of numerous innovative bone tissue engineering implants. Although additive manufacturing allows flexible patient-specific treatments by modifying topological properties with various materials, the development of ideal bone implants that aid new tissue regeneration and reduce post-implantation bone disorders has been limited. Natural biomolecules are gaining the attention of the health industry due to their excellent safety profiles, providing equivalent or superior performances when compared to more expensive growth factors and synthetic drugs. Supplementing additive manufacturing with natural biomolecules enables the design of novel multifunctional bone implants that provide controlled biochemical delivery for bone tissue engineering applications. Controlled release of naturally derived biomolecules from a three-dimensional (3D) printed implant may improve implant-host tissue integration, new bone formation, bone healing, and blood vessel growth. The present review introduces us to the current progress and limitations of 3D printed bone implants with drug delivery capabilities, followed by an in-depth discussion on cutting-edge technologies for incorporating natural medicinal compounds embedded within the 3D printed scaffolds or on implant surfaces, highlighting their applications in several pre- and post-implantation bone-related disorders.

Abstract
It is of interest to develop potent and safer anti-inflammatory drugs from plants, as medicinal plants and herbs attained great attention in the medical world due to their multifunctional activities. This article studied the anti-inflammatory effects of lauric acid (LA), thiocolchicoside (TC) and thiocolchicoside-lauric acid (TC-LA) formulation. The anti-inflammatory effects of these compounds were determined by following the methods of inhibition of protein denaturation and proteinase inhibition activity. This was assessed at different concentrations to determine the 50% inhibition concentration (IC50) of the compounds. The result indicated that the activity of LA, TC, TC-LA formulation, and reference drug increased with the increase in the concentration from 10-50 µg/ml, thus proving the activity of LA, TC, and TC-LA formulation against inflammation was in a dose-dependent manner. The percentage of inhibition of protein denaturation was 59.56%, 66.94%, 86.62%, and 60.34% for LA, TC, the combination of TC-LA and standard drug, and the IC50 values were found to be 44.78 µg/mL, 37.65 µg/mL, 27.15 µg/mL and 43.42 µg/mL, respectively. The percentage of proteinase inhibition activity of LA, TC, and a combination of TC-LA and the standard drug was 66.65%, 77.49%, 94.07%, and 69.83%, and IC50 of LA, TC, a combination of TC-LA and standard drug were35.5 µg/mL, 32.12 µg/mL, 24.35 µg/mL and 37.80 µg/mL, respectively. We found out that lauric acid, thiocolchicoside, and thiocolchicoside-lauric acid formulation exhibited significant anti-inflammatory activity.

JOURNAL OF ETHNOPHARMACOLOGY 2022; 283:114436. [PMID: 34289396 DOI: 10.1016/j.jep.2021.114436] [Citation(s) in RCA: 31] [Impact Index Per Article: 15.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 07/14/2021] [Accepted: 07/16/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Inflammation is a serious global concern due to its debilitating symptoms, resulting in considerable suffering and lost productivity. Chronic and auto-immune inflammatory diseases are of particular concern. Several pharmaceutical therapies are already available. However, the use of non-steroidal anti-inflammatory drugs (NSAID's) is accompanied by harmful and toxic side effects. Hence, the search for safer alternative therapeutics with limited side effects is imperative. The use of medicinal plants is common practice amongst the southern African population and may provide targets for drug development. AIM OF THE STUDY This study aims to review and document the medicinal uses and pharmacological properties of southern African medicinal plants used for inflammation and pain-related ailments. MATERIAL AND METHODS An extensive literature review was undertaken to identify southern African plants used traditionally to treat inflammation. A variety of ethnobotanical books and grey literature, as well as ScienceDirect, Google Scholar and Scopus search engines were used as sources of information. RESULTS This review identified 555 medicinal plants from 118 families which were traditionally used in southern Africa to treat inflammation and pain. Fabaceae was the most prominent family with 63 species, followed by Asteraceae (54 species) and Apocynaceae (33 species). The top category of ailments indicated include non-specific inflammation with 150 species, followed by inflammatory pain (148 species), headache (114 species) and toothache (114 species). CONCLUSION Despite a large number of southern African medicinal plants used to treat inflammation and pain, relatively few have been screened for their anti-inflammatory properties. Furthermore, biologically active plant extracts have been tested against relatively few inflammatory markers and considerable further work is required.

Abstract
Abstract
Background
Traditionally, the herb Byttneria pilosa Roxb. is used for bone fractures, boils, scabies, rheumatalgia, snake bites, syphilis, elephantiasis, poisoning, and eye infection. Scientific reports suggest that it has significant anti-inflammatory, analgesic, anti-diarrheal, anxiolytic, locomotion, sedative and anti-obesity effects. This study aims at the investigation of the phytochemical and pharmacological properties of the ethanol extract of this herb.
Methods
Fresh whole plant was extracted with absolute ethanol. A preliminary phytochemical investigation was followed by the evaluation of thrombolytic, anti-inflammatory, and anti-nociceptive activities by applying human clotted blood lysis, egg albumin, and acetic acid-induced writhing models, respectively.
Results
Phytochemical investigation suggests that B. pilosa possesses alkaloids, flavonoids, glycosides, terpenoids, tannins, saponins, and reducing sugars. The extract exhibited clot lysis and anti-inflammatory effects in a concentration-dependent manner. B. pilosa extract at 250 and 500 mg/kg also showed significant (p < 0.05) dose-dependent anti-nociceptive activity in Swiss albino mice.
Conclusion
The B. pilosa ethanol extract contains many important secondary metabolites and has thrombolytic, anti-inflammatory, and anti-nociceptive activities. More research is necessary on this hopeful medicinal herb.

Abstract
In this study, a simple, low-cost, rapid, and eco-friendly approach for the biosynthesis of silver nanoparticles (AgNPs) using the aqueous extract of Cuminum cyminum L. (cumin) seed (CcAgNPs) was developed. Also, the anti-nociceptive properties of these synthesized AgNPs were evaluated in vivo. The CcAgNPs characterized using Ultraviolet-visible (UV-Vis) spectrophotometer, X-ray diffraction analysis (XRD), Fourier transform infrared (FTIR) spectroscopy, atomic force microscopy (AFM), and transmission electron microscopy (TEM). The analysis of phytochemical components in the aqueous extract of cumin seeds showed high concentrations of total phenols and ascorbic acid and low concentrations of total flavonoids. The analysis of phytochemical components and FTIR spectroscopy confirmed the presence of functional groups responsible for the bioreduction of Ag+ to AgNPs. The UV-Vis absorbance spectrum of CcAgNPs showed a maximum wavelength at 442 nm. The analysis of TEM images showed a spherical shape with a size of less than 50 nm, while XRD spectra revealed the crystallinity of CcAgNPs. The analysis of anti-nociceptive properties of CcAgNPs showed that the first phase of formalin-induced pain was significantly reduced in the groups receiving 200, 500, and 1000 mg/kg CcAgNPs compared with the controls and the group receiving 300 mg/kg of sodium salicylate (SS300). The second phase of formalin pain was also significantly reduced in the groups receiving 200 and 500 mg/kg CcAgNPs compared to the controls and SS300 group. Overall, we introduced a new AgNPs synthesized from cumin seeds (CcAgNPs) and showed their anti-nociceptive properties in the formalin-induced pain.

Abstract
OBJECTIVE To test the effectiveness of a dentifrice containing the turmeric and licorice extract compared to a control for preventing plaque and gingivitis over a four-month period. MATERIAL AND METHODS Ninety (non-dental) participants with moderate gingival inflammation(≥40%) were selected. The triple blind study consisted of two phases, namely at first a 3-week pre-experimental phase of using an oxygenating and chlorhexidine (CHX) mouthrinse. Secondly, a 4-months experimental period in which participants were randomly assigned to a test or control group. All were instructed to brush their teeth twice daily for 2 minutes with their assigned dentifrice. Gingival bleeding(BI), plaque(PI) and gingivitis(GI) were assessed. RESULTS Eighty participants completed the protocol. At the first assessment in the pre-experimental phase, the mean scores of all indices showed no differences for the two groups. At the second session, the values of all three parameters had decreased significantly (p<0.001). At the last session the BI values were 0.52(0.25) for the test group and 0.56(0.25) for the control, the mean GI was 0.27(0.17) for the test group and 0.31 0.16) for the control, and for PI the scores were 1.89(0.46) for the test group and 1.98(0.43) for the control group. Statistical comparison of the scores for the two groups at each stage of the study showed no significant difference for any of the parameters. CONCLUSION Within the limits of the current study design, dentifrice formulation and concentration of turmeric/licorice extracts the results show that the adjuvant effect of the natural ingredients in the test dentifrice was not evident on clinical parameters of gingivitis and plaque.

Abstract
Plants represent the main source of molecules for the development of new drugs, which intensifies the interest of transnational industries in searching for substances obtained from plant sources, especially since the vast majority of species have not yet been studied chemically or biologically, particularly concerning anti-inflammatory action. Anti-inflammatory drugs can interfere in the pathophysiological process of inflammation, to minimize tissue damage and provide greater comfort to the patient. Therefore, it is important to note that due to the existence of a large number of species available for research, the successful development of new naturally occurring anti-inflammatory drugs depends mainly on a multidisciplinary effort to find new molecules. Although many review articles have been published in this regard, the majority presented the subject from a limited regional perspective. Thus, the current article presents highlights from the published literature on plants as sources of anti-inflammatory agents.

Abstract
The current work examined the outcome of curcumin (20 mg/kg body weight/day) administration on arginase and adenosine deaminase (ADA) activities and other kidney markers, as well as markers of oxidative stress, in Wistar rats exposed to sodium nitrite (NaNO2 ) (60 mg/kg of body weight, single dose) for 28 days. The results revealed that the NaNO2 exposed rats had significantly altered the ADA activities, arginase activities alongside other biomarkers of kidney function, and oxidative stress. However, pretreatment with curcumin significantly mitigated the altered activities ADA and arginase as well as other parameters. This was supported by the histopathological examination of the kidney tissues. Our findings suggest that the alteration in the activities of ADA and arginase could be involved in the mechanism of action employed by NaNO2 and curcumin in the respective induction and prevention of nephrotoxicity. PRACTICAL APPLICATIONS: These results suggest that moderate exposure to the acceptable daily dose of curcumin can improve food-related kidney damage through regulations of ADA and arginase activities, enhancement in the antioxidant system, and suppression of lipid peroxidation.

Abstract
Abstract
Background
Justicia secunda Vahl. is a medicinal plant used in ethnomedical practice as therapy to manage inflammation. Therefore, this study was designed to evaluate the anti-inflammatory activity of methanol extract of J. secunda leaves (MEJSL) using in vitro and in vivo inflammation models.
Methods
Seventy-percent MEJSL was prepared following standard procedure. In vitro anti-inflammatory assays were performed using heat-induced bovine serum albumin (BSA) denaturation and erythrocyte membrane stabilization assays. Carrageenan and formaldehyde induced inflammation in rat models were used to evaluate the anti-inflammatory activity of MEJSL in vivo. Diclofenac sodium was used as a reference drug. In addition, liver and kidney function assays and hematological analysis were carried out.
Results
Data revealed that varying concentrations of MEJSL significantly (P < 0.05) inhibited heat-induced BSA denaturation and stabilized erythrocyte membrane against hypotonicity-induced hemolysis when compared with diclofenac sodium in a concentration-dependent manner. In vivo study showed that 10 mg/kg body weight (b.w.) diclofenac sodium, 100 and 300 mg/kg b.w. MEJSL suppressed carrageenan-induced paw edema at the sixth hour by 71.14%, 83.08%, and 89.05%, respectively. Furthermore, 10 mg/kg b.w. diclofenac sodium, 100 and 300 mg/kg b.w. MEJSL inhibited formaldehyde-induced paw edema by 72.53%, 74.73%, and 76.48%, respectively. Animals treated with varying doses of MEJSL had reduced plasma aspartate aminotransferase and alanine aminotransferase activities; urea and creatinine concentrations; and modulated hematological parameters when compared with the untreated control group.
Conclusions
Findings from this study showed that MEJSL exhibited substantial anti-inflammatory actions in the in vitro and in vivo models. It also indicated that MEJSL anti-inflammatory mechanisms of action could be through interference with phase 2 inflammatory stressors, upregulation of cytoprotective genes, stabilization of inflammatory cell membranes and immunomodulatory activity.

Abstract
Abstract
Background
COX-2-specific inhibitors offer improved advantages over traditional NSAIDs. Plants are known to play critical roles in the discovery and developments of new pharmaceuticals. To the best of our knowledge, nothing has been reported so far on the selective inhibition of the cyclooxygenase by flavanones. The present study aims at evaluating the selective inhibition of COX-1 and/or COX-2 by flavanones from Sorghum bicolor.
Results
Flavanones demonstrate selective inhibition of COX-2 through the formation of hydrogen bonds. Eriodictyol forms two hydrogen bonds interactions (Tyr-371 and Ser-516) within the active site of COX-2, while it forms only one hydrogen bond (Met-521) with COX-1. Sorghum bicolor flavanone extract (SBFE) demonstrate hepatoprotective potentials by augmenting the antioxidant defense system of the liver and downregulate the expression of COX-2 while ineffective against COX-1. Histopathological analyses show that SBFE is effective in the prevention of HCl/ethanol-induced gastric injury in Wistar rats.
Conclusions
The side effects associated with current NSAIDs are as a result of selective inhibition of COX-1. Flavanones are potential selective inhibitors of COX-2. Sorghum bicolor flavanone extract (SBFE) demonstrates its anti-inflammatory potential through selective inhibition of COX-2. The virtual high throughput screening techniques adopted herein could help eradicate the corresponding rigors of identifying lead bioactive(s) components of plants.

Abstract
Spontaneous edible plants have an old history of use in popular traditions all around the world, and the rediscovery of these species could also be useful for the search of new drugs. Chenopodium album L. (Amaranthaceae) and Sisymbrium officinale (L.) Scop. (Brassicaceae) are two annual plants traditionally used both as food and herbal remedies against inflammatory disorders. In this work, the potential anti-inflammatory and anti-arthritic activities of these plant species have been investigated, together with their antioxidant potential. The phytochemical composition was assessed as well by means of gas chromatography coupled to mass spectrometry (GC-MS) and high performance thin layer chromatography (HPTLC). The antioxidant properties were assessed using the DPPH and β-carotene bleaching test. The ability of extracts to protect against lipid peroxidation was also examined in rat-liver microsomal membranes. All the samples showed a preservation of antioxidant activity up to 60 min. A significant inhibitory activity on the production of the pro-inflammatory mediator nitric oxide was induced in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells by the dichloromethane fraction of C. album extract, with an IC50 value equal to 81.7 ± 0.9 μg/mL. The same sample showed also a concentration-dependent anti-denaturation effect on heat-treated bovine serum albumin (IC50 = 975.6 ± 5.5 μg/mL), even if the best in vitro anti-arthritic activity was observed for the dichloromethane fraction of S. officinale extract, with an IC50 value of 680.9 ± 13.2 μg/mL.

JOURNAL OF INTEGRATIVE MEDICINE-JIM 2017; 16:62-70. [PMID: 29397096 DOI: 10.1016/j.joim.2017.12.009] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 05/03/2017] [Accepted: 08/05/2017] [Indexed: 12/20/2022]
Abstract
OBJECTIVE Anacardium occidentale L. leaf is useful in the treatment of inflammation and asthma, but the bioactive constituents responsible for these activities have not been characterized. Therefore, this study was aimed at identifying the bioactive constituent(s) of A. occidentale ethanolic leaf extract (AOEL) and its solvent-soluble portions, and evaluating their effects on histamine-induced paw edema and bronchoconstriction. METHODS The bronchodilatory effect was determined by measuring the percentage protection provided by plant extracts in the histamine-induced bronchoconstriction model in guinea pigs. The anti-inflammatory effect of the extracts on histamine-induced paw edema in rats was determined by measuring the increase in paw diameter, after which the percent edema inhibition was calculated. The extracts were analyzed using gas chromatography-mass spectrometry to identify the bioactive constituents. Column chromatography and Fourier transform infrared spectroscopy were used respectively to isolate and characterize the constituents. The bronchodilatory and anti-inflammatory activities of the isolated bioactive constituent were evaluated. RESULTS Histamine induced bronchoconstriction in the guinea pigs and edema in the rat paw. AOEL, hexane-soluble portion of AOEL, ethyl acetate-soluble portion of AOEL, and chloroform-soluble portion of AOEL significantly increased bronchodilatory and anti-inflammatory activities (P < 0.05). Oleamide (9-octadecenamide) was identified as the most abundant compound in the extracts and was isolated. Oleamide significantly increased bronchodilatory and anti-inflammatory activities by 32.97% and 98.41%, respectively (P < 0.05). CONCLUSION These results indicate that oleamide is one of the bioactive constituents responsible for the bronchodilatory and anti-inflammatory activity of A. occidentale leaf, and can therefore be employed in the management of bronchoconstriction and inflammation.

Abstract
The present study was designed to investigate the antioxidant, antinociceptive and anti-inflammatory activities of the ethanol extract from Ageratum fastigiatum branches. Phytochemical screening and total phenol and flavonoid contents were determined. The antioxidant activity was assessed by 2,2-diphenyl-1-pycrilhydrazin (DPPH) and iron reducing power methods. The antinociceptive effect was evaluated using the acetic acid-induced writhing, formalin, hot plate and tail immersion assays; while the carrageenan-induced paw edema and pleurisy tests were performed to examine the anti-inflammatory activity against acute inflammation. The extract revealed the presence of flavonoids, tannins, coumarins, terpenes, sterols and saponins. Expressive levels of total phenols and flavonoids and a promising antioxidant effect were quantified. At the doses of 50, 100 and 200 mg/kg, the extract inhibited the writhing, reduced both phases of paw licking time and increased the reaction time on the hot plate. In the tail immersion test, the extract (50, 100 and 200 mg/kg) caused a significant inhibition of pain. In these doses, the paw edema, exudate volume and leucocyte mobilization were significantly reduced. These results suggest that A. fastigiatum can be an active source of substances with antioxidant, antinociceptive and anti-inflammatory activities, adding scientific support to the appropriate use in the Brazilian folk medicine.

Abstract
BACKGROUND Inflammation is a common risk factor in the pathogenesis of conditions such as infections, arthritis, type 2 diabetes mellitus, obesity and cancer. An ethnobotanical survey of medicinal plants used traditionally to treat inflammation and related disorders such as pain, arthritis and stomach aches in southern Africa led to the selection of 25 plant species used in this study. METHODS The antioxidant activities of acetone extracts were determined by measuring the free radical scavenging activity and ferric reducing ability, respectively. The anti-inflammatory activities of the extracts were determined by measuring the inhibitory effect of the extracts on the activities of the pro-inflammatory enzyme, lipoxygenase and inducible nitric oxide synthase. RESULTS Extracts of Peltophorum africanum had good antioxidant activity with IC50 values of 4.67 ± 0.31 μg/mL and 7.71 ± 0.36 μg/mL compared to that of the positive control ascorbic acid (2.92 ± 0.14 μg/mL and 13.57 ± 0.44 μg/mL), using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging and 2,2'-azinobis (3-ethylbenzthiazoline-6-sulphonic acid (ABTS) methods, respectively. The metabolism of linoleic acid to leukotriene derivatives by 15-lipoxygenase (15-LOX) was also inhibited by the crude acetone extracts of Peltophorum africanum (IC50 = 12.42 μg/mL), Zanthoxylum capense (IC50 = 14.92 μg/mL) compared to the positive control quercetin (IC50 = 8.75 μg/mL). There was a poor correlation between the flavonoid content and 15-LOX inhibition by the extracts (R(2) = 0.05), indicating that flavonoids are not involved in LOX inhibition. Extracts of Clausena anisata, at a concentration of 6.25 μg/mL inhibited nitric oxide production by RAW 264.7 macrophage cell lines in vitro by 96 %. The extracts of Zanthoxylum capense were the least cytotoxic (IC50 > 1000 μg/mL) when the extract toxicity was determined against Vero (African green Monkey) kidney cell lines. CONCLUSION Some plant species used traditionally to treat pain have reasonable anti-inflammatory activity and flavonoids are probably not involved in this process.

Abstract
Background Hematopoietic prostaglandin D2 synthase (H-PGDS, GST Sigma) is a member of the glutathione S-transferase super family of enzymes that catalyses the conjugation of electrophilic substances with reduced glutathione. The enzyme catalyses the conversion of PGH2 to PGD2 which mediates inflammatory responses. The inhibition of H-PGDS is of importance in alleviating damage to tissues due to unwarranted synthesis of PGD2. Combretum molle has been used in African ethno medicinal practices and has been shown to reduce fever and pain. The effect of C. molle alkaloid extract on H-PGDS was thus, investigated. Methods H-PGDS was expressed in Escherichia coli XL1-Blue cells and purified using nickel immobilized metal affinity chromatography. The effect of C. molle alkaloid extract on H-PGDS activity was determined with 1-chloro-2, 4-dinitrobenzene (CDNB) as substrate. The effect of C. molle alkaloid extract with time on H-PGDS was determined. The mechanism of inhibition was then investigated using CDNB and glutathione (GSH) as substrates. Results A specific activity of 24 μmol/mg/min was obtained after H-PGDS had been purified. The alkaloid extract exhibited a 70% inhibition on H-PGDS with an IC50 of 13.7 μg/ml. C. molle alkaloid extract showed an uncompetitive inhibition of H-PGDS with Ki = 41 μg/ml towards GSH, and non-competitive inhibition towards CDNB with Ki = 7.7 μg/ml and Ki′ = 9.2 μg/ml. Conclusion The data shows that C. molle alkaloid extract is a potent inhibitor of H-PGDS. This study thus supports the traditional use of the plant for inflammation.

Abstract
Acanthus ebracteatus Vahl. is a Thai herb that is effective in wound healing. We sought to quantitatively determine whether or not the combined application of Acanthus ebracteatus Vahl. and a collagen scaffold will increase wound closure and angiogenesis. Balb/c mice (body weight: 22-25 g) were anesthetized with sodium thiopental. The dorsal skin incision measuring 1.5 × 1.5 cm was made and then deepened using scissors to produce a full-thickness incision down to the level of the panniculus carnosus. The size of the wound was approximately 10% of the total body surface area. The collagen sheet was implanted onto the wound. Animals were divided into 4 major groups as follows: wound with normal saline (W-NSS), wound treated with 0.3 g/kg BW of Acanthus ebracteatus Vahl. extract (W-AE (0.3 g/kg.bw)), wound implanted with collagen scaffold (W-Coll), and wound implanted with collagen scaffold and treated with 0.3 g/kg BW of Acanthus ebracteatus Vahl. (W-Coll-AE combination). On day 14, the W-Coll-AE group showed decreased wound areas and increased capillary vascularity (CV) when compared to the other 3 groups, W-NSS, W-AE0.3, and W-Coll. In the present study, the combination of AE0.3 with collagen showed the best effect on skin angiogenesis and promoted wound closure with less neutrophil infiltration.

Abstract
Background Sesquiterpene lactones (SL) are plant secondary metabolites that are known for their anti-fungal, anti-bacterial, anti-inflammatory, and anti-tumor properties. Considering that several SL-derived drugs are currently in cancer clinical trials, we have tested two SL molecules, 3-β-methoxy-iso-seco-tanapartholide (β-tan) isolated from Achillea falcata and salograviolide A (Sal A) isolated from Centaurea ainetensis, for their anti-tumor properties. We used the mouse epidermal JB6P + cells as a model for tumor promotion and cellular transformation. Key players that are involved in cellular transformation and tumorigenesis are the AP-1 and NF-κB transcription factors; therefore, we assessed how β-tan and Sal A modulate their signaling pathways in JB6P + cells. Methods The effects of β-tan and Sal A on the growth of normal and neoplastic keratinocytes and on the tumor promotion-responsive JB6P + cells were determined using the MTT assay. Anchorage-independent cell growth transformation assays were used to evaluate the anti-tumor promoting properties of these SL molecules in JB6P + cells and dual luciferase reporter assays and western blot analysis were used to investigate their effects on tumor promoter-induced AP-1 and NF-κB activities and protein levels of key AP-1 and NF-кB target genes. Results β-tan and Sal A selectively inhibited tumor promoter-induced cell growth and transformation of JB6P + cells at concentrations that do not affect JB6P + and primary keratinocytes basal cell growth. In addition, both molecules reduced basal and tumor promoter-induced NF-κB transcriptional activities, differentially regulated basal and tumor promoter-induced AP-1 transcriptional activities, and modulated key players of the AP-1 and NF-κB signaling pathways. Conclusions These results highlight the anti-tumor promoting properties of β-tan and Sal A. These SL molecules isolated from two plant species native to the Middle East may provide opportunities for complementary medicine practices.

Abstract
Ardisia species (Myrsinaceae) are found throughout tropical and subtropical regions of the world. Traditional medicinal uses attributed to Ardisia include alleviation of liver cancer, swelling, rheumatism, earache, cough, fever, diarrhea, broken bones, dysmenorrhea, respiratory tract infections, traumatic injuries, inflammation, pain, snake and insect bites, birth complications and to improve general blood circulation, among others. Ardisia species are rich in polyphenols, triterpenoid saponins, isocoumarins, quinones and alkylphenols. A summary of the uses, potential health benefits, adverse reactions and important bioactive phytochemicals isolated from the Ardisia species is presented. Future research needs to include more toxicological studies, more comprehensive chemical characterization of extracts, bioavailability, extract standardization, investigation of possible herb-drug interactions, plant improvement with regards to bioactivity and composition, and additional human and animal studies to confirm the health-promoting properties claimed for Ardisia species. The information presented here exemplifies the potential of Ardisia species as a source of chemotherapeutic, chemo-modulating and/or chemopreventive agents.
