In our continuous search for α-glucosidase inhibitors, three active pentacyclic triterpenes were isolated from stem bark samples of the Panamanian mangrove Pelliciera rhizophorae Triana & Planchon. These compounds were identified by both spectroscopic and spectrometric analysis. Of the isolated compounds, only betulinic acid has been previously isolated from P. rhizophorae leaves while both betulin (IC50 2.09 μM) and lupeol (IC50 0.58 μM) were isolated from this plant for the first time. All three pentacyclic triterpenes inhibited the α-glucosidase enzyme in a concentration-dependent manner, and their inhibitory activity was higher than that of the antidiabetic drug acarbose (IC50 241.6 μM). Kinetic analysis established that betulin and lupeol acted as competitive inhibitors. Finally, docking analysis suggested that all three triterpenes bind at the same site as acarbose does in the human intestinal α-glucosidase (PDB: 3TOP). This work contributes further evidence similar to previous studies that point out that the aerial parts of P. rhizophorae might be potential agents in controlling hyperglycemia in diabetic persons.

Tectona grandis L. f. (Lamiaceae) is famous for timber production and has been used in traditional medicine for treating bronchitis, liver-related  roubles, urinary discharge amongst other diseases. Methanol extract of  the stem bark was investigated for in vivo antiophidian assay against Bitis arietans and Naja nigricollis. Also, the extract and chromatographic fractions were subjected to cytotoxicity tests using tadpole model and  antiarthritic assay by proteinase inhibition. Chromatography of crude methanol extract afforded three highly polar vacuum liquid chromatography (VLC) fractions (BVLC-1, BVLC-2 and BVLC-3). BVLC-2 further gave four semi-pure uncharacterized isolates (I, II, III, IV). Only BVLC-2 and BVLC-3 were cytotoxic at 10 - 80 mg/ml, with BVLC-3 being most potent (100% mortality, LC50 40 mg/ml). Concentration-dependent proteinase enzyme inhibition (24 - 71%) at 200 - 1000 μg/ml of BVLC-2 was observed, and this was less (IC50 659.24 μg/ml) than the activity of the standard drug, acetyl salicylic acid. However, neutralization of B. arietans and N. nigricollis snake venoms using methanol extract was not dose-dependent, but the extract atthe least dose, 50 mg/kg offered better protection (75%) on Naja nigricollis envenomed-mice in 48 h. Its activity was comparable to that of the positive antivenin tested at 0.2 mg/kg. These findings justify the folkloric use of T. grandis in the treatment of snake bites, arthritic conditions, and oxidative stress-induced diseases. Keywords: Tectona grandis, methanol extract, anti-snake venom activity, tadpole cytotoxicity, anti-arthritic activity

Songi (Dillenia serrata) is a tree endemic to Southeast Sulawesi and its stem bark been used in folk medicine. Nonetheless, only a handful scientific knowledge regarding chemistry and biological activities has been investigated on the plant. The present study aimed to investigate the antioxidant and xanthine oxidase (XO) inhibitory activity of the stem bark of the plant. Methanol extract and organic fractions (petroleum ether, ethyl acetate, and methanol) of the dried powdered stem bark of songi were evaluated for phytochemical screening, total phenolic (TPC), total flavonoid contents (TFC), DPPH, FRAP, and XO in vitro assays. Flavonoids, tannins, terpenoids, steroids, and saponins present in the extract. TPC and TFC in extract were 59.2 mg GAE/g and 23.4 mg QE/g. The contents in organic fractions were in solvent-dependent manner (methanol>ethyl acetate>petroleum ether). Extract and fractions scavenged DPPH radicals (48.2–59.7%) at 100 μg/mL compared to ascorbic acid, trolox, and gallic acid (90.3–93.8%). FRAP values varied from 0.8–3.4 μg/μg equivalent trolox amount (quercetin and gallic acid were 25.7 dan 32.4 μg/μg, respectively). They also inhibited xanthine oxidase (15.3–50.3%) at 100 μg/mL (allopurinol, 98.2%). The study concluded the potential of methanol extract and organic fraction of the stem bark of songi, thus highlighted the prospect of songi to be used in herbal and drugs development from nature.

Objective: To determine the potential effect of Pyrenancantha staudtii extract on experimentally induced seizures in mice and to evaluate the role of benzodiazepines, naloxone, and serotonin within these pathways. Methods: Animal behaviours were evaluated using open field, hexobarbitone-induced sleep model, and anticonvulsant activity using picrotoxin-, or strychnine-, or isoniazid-induced convulsions. Attempt to understand the mode of action of the anticonvulsant activity of the plant, three notable antagonists (flumazenil, 3 mg/kg; naloxone 5 mg/kg, i.p., and cyproheptadine, 4 mg/kg, i.p) were used. Results: The results revealed a significant (p < 0.05) reduction in the frequency of rearing and grooming episodes compared with the control. The extract of P. staudtii potentiates the sleeping time of hexobarbitone-induced hypnosis in a dose-related manner. P. staudtii stem bark extracts significantly (p<0.05) prolonged the onset of a seizure and attenuated the duration of seizure in a dose-dependent manner in picrotoxin- and or isoniazid-induced seizures. While, P. staudtii stem bark extract at all doses (100, 200, and 400 mg kg-1) though significantly prolonged the onset of action, but did not confer any significant changes on the duration, as well as mortality in this strychnine-induced seizure model. However, the anticonvulsant activity of the methanolic extract of P. staudtii was significantly reversed following intraperitoneal pre-treatment with flumazenil (GABA receptor antagonist) and naloxone (opioid receptor antagonist) but not cyproheptadine (5-HT2 receptor antagonist) in picrotoxin-induced convulsion. Conclusion: The data obtained suggest that methanol extract of P. staudtii possessed significant anticonvulsant effect, thereby confirming the traditional uses of P. staudtii in the treatment of epilepsy; mechanisms of which could involve the interaction with GABAergic and or opioidergic system.

Background:<em> Anthocephalus cadamba </em>(Rebox)Miq. (Rubiaceae) is widely distributed throughout the greater part of India, especially at low levels in wet place. Traditionally the bark is used as tonic, febrifuge and to reduce the pain and inflammation. The anti-inflammatory effect of methanol extract obtained from <span style="font-style: italic;"> Anthocephalus cadamba </span> aerial parts, MEAC, were investigated in this study. Design and methods: The effects of MEAC on the acute and chronic phases of inflammation were studied in carrageenan, dextran and mediators (histamine and serotonin) induced paw edema and cotton pallet-induced granuloma, respectively. The anti-edema effect of MEAC was compared with 10 mg/kg of indomethacin orally. Results: The results suggested that MEAC possess potent anti-inflammatory activity. The acute inflammatory model showed that all the doses of MEAC effectively suppressed the edema produced by histamine, so it may be suggested that its anti-inflammatory activity is possibly backed by its antihistaminic activity. In chronic inflammatory model the effect may be due to the cellular migration to injured sites and accumulation of collagen and mucopolysaccharide. Conclusions: On the basis of these findings, it may be inferred that <span style="font-style: italic;"> Anthocephalus cadamba </span> is an anti-inflammatory agent and the results are in agreement with its traditional use.

AbstractBreast cancer is the most common carcinoma in women, and natural products would be effective preventing some side effects of cancer treatment. In the present study, cytotoxic activities of different Iranian Chrysanthemum morifolium cultivars were evaluated in human breast cancer cell lines (MCF-7) and human lymphocytes. A systems pharmacology approach was employed between major compounds of these cultivars (chlorogenic acid, luteolin, quercetin, rutin, ferulic acid, and apigenin) and known breast cancer drugs (tucatinib, methotrexate, tamoxifen, and mitomycin) with 22 breast cancer-related targets to analyze the mechanism through which Chrysanthemum cultivars act on breast cancer. Target validation was performed by the molecular docking method. The results indicated that Chrysanthemum extracts inhibited the proliferation of MCF7 cells in a dose- and cultivar-dependent manner. In all studied cultivars, the most effective extract concentration with the lowest viability of MCF-7 cells, was as much as 312 µg ml−1. Also, higher concentrations of the extracts (> 1000 µg ml−1) reduced the lymphocyte cell viability, demonstrating that these doses were toxic. The gene ontology analysis revealed the therapeutic effects of Chrysanthemum’s active compounds on breast cancer by regulating the biological processes of their protein targets. Moreover, it has been documented that rutin, owing to its anticancer effects and several other health benefits, is a promising multi-targeted herbal ingredient. Finally, the present study compared different Iranian Chrysanthemum cultivars to provide new insights into useful pharmaceutical applications.

Background: The aerial parts of Dipsacus laciniatus are traditionally used in the treatment of colds as cold tea; decoction prepared from its roots and aerial parts are used for the treatment of diabetes and cancer, respectively. The extraction procedures and solvents are important steps in the processing of bioactive constituents from the plant materials. Objective: The aim of this study was to evaluate in vitro antioxidant, antimicrobial, anticholinesterase and cytotoxic activities for the first time in plant’s different extracts. Methods: The antioxidant activities of extracts were examined using FRAP and CUPRAC methods, including total phenolic and flavonoids contents. In addition, the antimicrobial, anticholinesterase and cytotoxic activities of extracts were investigated using microdilution, Ellman and MTT methods, respectively. Results: In the present study, methanol extract showed stronger iron (III) ion reduction (FRAP) and copper (II) ion reducing antioxidant capacity (CUPRAC) than other extracts and also contained higher total phenolic and flavonoid compounds. It was also found that there was a linear relationship between antioxidant activity and phenolic compounds in this study. It was demonstrated that the chloroform and methanol extracts showed moderate antimicrobial activity against S. epidermidis and C. albicans strains. The chloroform extract had a strong and selective cytotoxic activity for the MCF-7 and HT-29 cell lines, while the methanol extract showed low cytotoxic activity on the same cell lines. In addition, according to the obtained data, chloroform extract showed a toxic effect on normal cell line (NIH/3T3), but other extracts showed no toxic effect. Conclusion: Since methanol extract has no toxic effect on normal cell line and has strong antioxidant, anticholinesterase and antimicrobial activity, it is thought that this extract may be useful as an antioxidant, anticholinesterase and antimicrobial agents in the future.

Anthocleista vogelii (Loganiaceae) PLANCH. is used in Cameroonian ethnomedicine for the treatment of stomach ache and for curing fever and is used as purgative. Further investigations have shown that the stem bark of this plant possesses potent antiulcer properties. We have investigated the cytoprotective and antisecretory actions of 1-hydroxy-3,7,8-trimethoxyxanthone (AV), the xanthone obtained from the methanol extract of the stem bark. Oral administration of AV at the doses of 1, 2, and 5 mg/kg prevented in a dose-dependent manner ulcers induced by HCl/ethanol (60.90 to 93.22%), Indometacin (46.86 to 89.68%), and pylorus ligation (0.00 to 70.69%). AV reduced pylorus-ligated gastric acid secretion from 134.17 mEq/l in the controls to 118.55, 121.50, and 96.93 mEq/l, respectively, for the 1, 2, and 5 mg/kg doses and increased mucus secretion significantly in a dose-dependent manner in all experimental models. The cytoprotective and antisecretory properties of AV could thus be due to its ability to strengthen gastric mucosal defences through enhanced gastric mucus production.

Satureja cuneifolia Ten. (wild savoury) belongs to the Lamiaceae family and is used to produce essential oil and aromatic water. This plant is also used as a condiment and herbal tea due to its stimulating, tonic and carminative effects. The in vitro antioxidant, anti-urease, anticholinesterase and cytotoxic activities of the different extracts from the plant’s aerial parts were examined. Besides, the in vivo anti-inflammatory activities of the fraction and direct methanol extracts were determined comparatively. In the current study, fraction methanol extract exhibited the strongest ABTS (52.34 mM trolox/mg extract) radical scavenging and ferric reduction (17.22 mM Fe2+/mg extract) activity. It was also found that the fraction methanol extract had stronger anti-urease (12.52%) and anticholinesterase (69.02%) activity than other extracts.  The XTT results showed that fraction methanol extract had the most cytotoxic activity on MCF-7 cell lines (39.92%).  According to the results of in vivo anti-inflammatory activity, it was found that both fraction and direct methanol extracts exhibited close and significant anti-inflammatory activity. The fact that methanol extracts have significant biological activity suggests that these may be used as a natural source in the future.
