Abstract: Abstract Long-term use of tamoxifen (TAM) is associated with severe side effects. The present study aimed at evaluating the protective effect of the ethanolic extract of Aframomum angustifolium seeds (EEAA) against some adverse effects of TAM in female Wistar rats with 7,12-dimethybenz-(a)-anthracene (DMBA)-induced breast cancer. Breast cancer was induced through the subcutaneous administration of 50 mg/kg, bw of DMBA while normal rats constituted the control group. Twelve weeks later, breast cancer rats were randomised 5 per group and treated or not with 3.3 mg/kg, bw of tamoxifen alone, or tamoxifen plus either 150 or 300 mg/kg, bw of EEAA during 28 days, after which all animals were sacrificed under anaesthesia. The effects of the treatment on the uterus, body weight, lipid profile, liver and kidneys were evaluated. The EEAA at 300 mg/kg, bw significantly prevented tamoxifen-induced uterus’s hyperplasia by reducing serum estradiol level from 896.85 ± 54.57 (tamox alone) to 639.81 ± 43.41 pg/L. The extract at both doses prevented metabolic disturbance by increasing body weight, lowering triglyceride and total cholesterol levels and also prevented lipids accumulation in the liver. Catalase activity and TBARS levels were ameliorated (p < 0.05) in the liver and kidneys leading to the improvement of the integrity of these organs. Also, an amelioration of plasmatic activities of transaminases alkaline phosphatase and uric acid levels was noted. The ethanolic extract of Aframomum angustifolium seeds can be considered a potential source of bioactive compounds for the management of the side effects of TAM among breast cancer patients.

Abstract: Abstract Curcumin (Curc) has been shown to have the potential to ameliorate or prevent the development of Alzheimer's disease (AD). However, most of them are in vitro and in vivo short-term studies. This study was conducted to investigate whether long-term, low-dose dietary Curc intake in mouse of AD might suppress short-term memory retention, amyloid-beta (Aβ) deposition and tau phosphorylation, delaying the onset of AD and prolonging the lifespan of the animals. Short-term memory was examined by the Y-maze method after 6 months old. Immunohistochemical analysis was performed at 10 months old to determine changes in Aβ deposition, tau phosphorylation, and glial cell number in brain tissue. Furthermore, we investigated the survival rate for 12 months old and evaluated the AD prevention effect. The alternation rates of short-time memory in the wild type and AD mice were 56.2% and 25.9%, respectively. These rates in the experimental groups (0.02% and 0.5% Curc) were in the range of 44.4–45.7%. The area of Aβ42 deposition in AD mice was approximately 25,000 µm2, while the experimental groups had a significantly reduced area of 5000–10,000 µm2. Survival rate was 34% in the AD control group, 100% in the 0.02% Curc, and 83% in the 0.5% Curc group, significantly longer in the Curc groups than the AD control group. This study demonstrates that long-term intake of low concentrations of Curc may act on the tau- phosphorylation, suppress brain inflammation, delay the onset of AD, and prolong the lifespan of the mouse.

Abstract: Abstract Essential oils are combinations of naturally occurring phytochemicals that, alone or in synergy with other compounds, can therapeutically attenuate disease-causing viral infections such as SARS-CoV-2, Ebola, and Marburg viruses. This study aimed to investigate the biosafety of and identification of antiviral phytochemicals of Spondias mombin (Linn) leaf crude extracts by GC–MS analysis. GC–MS analysis showed that the compound concentrations were dependent on the polarity of extracting solvent SMH (34), SMDCM (36), SMEA (12), SME (50) and SMM (36). Toluene (15.13%) and di-isooctyl phthalate (14.21%) were identified as the basic constituents of SMH. In SMDCM, n-nonadecanol-1 (19.64%) and eicosane (13.93%) were the main compounds, while in SMEA it was ethanol, 2-butoxy-(83.29%). Both SME and SMM showed the presence of Tetradecyl trifluoroacetate (15.43%). Pentadecanoic acid (12.18%), Propane, 2,2-diethoxy- (33.83%) and o-Xylene (15.87%). The identified antiviral compounds in the crude extracts, were d-Limonene (1.33%), p-Cymene (1.31%), Thymol (0.50%) and Carvacrol (0.87%) in SMM and SMH extracts, with Phytol, acetate being a common constituent in all the essential oils, except SMEA. In vitro cytotoxicity studies of crude S. mombin leaf extracts were performed using the MTT method in three cell lines: MCF-7, A-549 and HEK-293, with IC50 values between 15.91 and 178.5 μg/mL. Therefore, the results indicated that crude extracts from S. mombin leafs had low toxicity and could be used safely. Compared with hexane extracts (1), methanol extracts have more compounds with antiviral properties (3) and can be used as reusable therapeutic candidates, natural dietary supplements or in the fight against SARS-CoV-2, Ebola and Marburg viruses. This can be valuable in pharmaceutical preparations of drug candidates for the treatment of these viruses.

Abstract: Abstract Dermatomycosis is a commonly occurring widespread superficial fungal infection. The infection is mostly caused by the dermatophytes (e.g., Trichophyton spp.), and yeasts (e.g., Candida spp.). Due to their persistent, recalcitrant nature and treatment failure it has become a worldwide concern. In our study, we have used multidrug-resistant Trichophyton mentagrophytes var. interdigitale clinical isolates for evaluation of the synergistic effect of the plant-based extract with existing drugs. Here, Punica granatum peel (PGP) extracts alone and their combination with existing antifungal drugs (e.g., Ciclopirox olamine, Zinc pyrithione, Ketoconazole, and Fluconazole) were evaluated as an alternative synergistic combination against Trichophyton and Candida species. Synergy had been determined for PGP extract with other antifungals against Candida and Trichophyton species by checkerboard, ZOI (zone of inhibition), and E-test methods respectively. The isolates exhibited resistance towards some azoles and allylamines. PGP extract alone and in combination with other antifungals had shown, FIC Index from 0.133 to 0.2 against C. albicans strains, 0.2 to 0.5, FIC against T. rubrum strains respectively. E-test also showed 512±0.0 and 341.3±0.0-fold decrease of MIC (minimum inhibitory concentration), against azole-resistant C. albicans MTCC 227 respectively. The study reveals that PGP extract alone and in combination with other antifungals is a promising source of alternative antifungal therapy to minimize the resistance profile.

Abstract: Abstract Gastric cancer was classified as the third most deadly cancer among all other cancer types. The HSP90 and HER2 genes play essential roles in the stability and function of high-expression proteins that cause malignancy. The aim of this research was to investigate the influence of the alcoholic Alkanna bracteosa extract on the expression of HSP90α and HER2 genes in AGS cell line. Therefore, the methanolic extraction was isolated from aerial parts of the plant and AGS and HuGu cell lines were analyzed using 102.4–0.05 mg ml−1 dose concentrations in serial dilution; to measure the cell toxicity by MTT assay. Furthermore, real-time PCR analysis measured the expression level of HSP90α and HER2 genes using the IC50 dose concentrations. Quantification of apoptosis was analyzed by Annexin/PI kit in flow cytometry and DNA fragmentation tests. The results of MTT assay represented the IC50 dose concentration of 0.8 and 3.2 mg ml−1 for AGS and HuGu respectively. The rate of HER2 gene expression was significantly decreased in AGS cells treated with 0.8 mg ml−1 dose concentration compared to control. The exposure of AGS treated cells with 0.8 mg ml−1 dose concentration after 24 h represented 24.3% apoptosis and 13.3% necrosis. The agarose gel represented the DNA fragmentation pattern of apoptosis. This study demonstrated the significant differences between the cell viability rate, gene expression level, and apoptosis of the Alkanna bracteosa extract on AGS cells. These results demonstrated the first report of which the Alkanna braceteosa would be an effective candidate for possible treatment of Gastric cancer.

Abstract: Hyper-pigmentation conditions may develop due to erroneous melanogenesis cascade which leads to excess melanin production. Recently, inhibition of tyrosinase is the main focus of investigation as it majorly contributes to melanin production. This inhibition property can be exploited in medicine, agriculture, and in cosmetics. Present study aims to find a natural and safe alternative molecule as tyrosinase inhibitor. In this study, human tyrosinase enzyme was modelled due to unavailability of its crystal structure to look into the degree of efficacy of glabridin and its 15 derivatives as tyrosinase inhibitor. Docking was performed by Autodock Vina at the catalytic core enzyme. Glabridin effects on melanoma cell lines was also elucidated by analysing cytotoxicity and effect on melanin production. Computational ADME analysis was done by SwissADME. Molecular dynamic simulation was also performed to further evaluate the interaction profile of these molecules and kojic acid (positive inhibitor) with respect to apo protein. Notably, four derivatives 5′-formylglabridin, glabridin dimer, 5′-prenyl glabridin and R-glabridin exhibited better binding affinity than glabridin. Glabridin effectively inhibited melanin production in a dose dependent manner. Among these, 5′-formylglabridin displayed highest binding affinity with docking score − 9.2 kcal/mol. Molecular properties and bioactivity analysis by Molinspiration web server and by SwissADME also presented these molecules as potential drug candidates. The study explores the understanding for the development of suitable tyrosinase inhibitor/s for the prevention of hyperpigmentation. However, a detailed in vivo study is required for glabridin derivatives to suggest these molecules as anti-melanogenic compound. Graphical abstract

Abstract: Zanthoxylum species are credited with various uses in ethnomedicine due to their rich metabolite composition. In Kenya, these include management of cancer and microbial related ailments. However, there are limited reports showing how the bioactivity of Kenyan Zanthoxylum species is linked to their phytochemical profiles. This study therefore aimed at examining the chemical variation among five Zanthoxylum species found in Kenya (Z. chalybeum, Z. gilletii, Z. holtzianum, Z. paracanthum and Z. usambarense) using metabolomics approaches and the anti-oxidant and antimicrobial activities of these species. In a Folin–Ciocalteu test, the phenolic content of the stem bark extracts of these species were 73.083–145.272 mg TAE/g, while the alkaloids (in bromothymol blue chromogenic test) and flavonoids (in aluminium chloride test) were found to be 152.39–207.19 mg ME/g, and 109.416–186.413 mg CE/g, respectively. These extracts also exerted strong antioxidant activities in the 2,2-iphenyl-1-picrylhydrazyl (DPPH) and ferric ion reducing antioxidant power assays. In a broth dilution assay, the extract of the stem bark of Z. holtzianum ability showed the highest antimicrobial activity, followed by Z. chalybeum stem bark extract. The activities were positively correlated to both flavonoids and alkaloids concentrations, while the concentration of phenolics had weak negative correlation to antimicrobial activities. A chemometric analysis of the liquid-chromatography mass spectrometry profiles led to grouping of the species into three clusters. This study illustrates the variation in the bioactivity of Zanthoxylum species based on metabolite composition and justifies the wide usage of Zanthoxylum species in Kenyan traditional medicinal practices.

Abstract: Abstract Mentha longifolia L. is used in folk medicine and its essential oil has antimicrobial and aromatic properties. The present invention relates to the development of hydrogel formulation of Mentha longifolia essential oil (EOML) for treating oral candidiasis. Various EOML hydrogels were developed using mucoadhesive polymers viz., Carbopol 940, sodium carboxymethylcellulose and their blends. The hydrogels were characterized with respect to physical, rheological and textural attributes. Finally, all the EOML based hydrogels were evaluated for in vitro efficacy against Candida albicans employing agar well diffusion and broth dilution assay. The EOML hydrogels were semisolid, off-white color, non-gritty, most stable at 4 and 25 °C, and possessed optimum spreading and pleasing aesthetic attributes. The hydrogels showed pseudo-plastic shear-thinning behaviour and variable viscosity, dependent on the concentration and type of gelling agent. The single polymer-based formulations (F1 and F2) were able to spread better compared to blended polymer formulations (F5 and F6). In broth dilution assay, of all the prepared mucoadhesive hydrogels, F1 (containing 5% Carbopol 940) exhibited lowest MIC value against Candida albicans (ATCC90028 and MTCC277), vis-a-vis EOML and standard drugs (i.e., Amphotericin B and Fluconazole). Further, there was marked enhancement in the antifungal efficacy of F1 in comparison to EOML (20 folds), Amphotericin B (2 folds) and Fluconazole (2 folds). Thus, the hydrogel formulation ensured reduced volatility of EOML and improved its therapeutic effectiveness. Owing to the mucoadhesive components and non-toxic properties of the EOML hydrogel, the formulation can be extended for clinical evaluation for treating oral thrush.

Abstract: Abstract Lignocaine is a local anaesthetic used in castration of dogs. However, lignocaine is sometimes combined with adrenaline in order to prolong the anaesthetic effect. Either lignocaine or lignocaine-adrenaline combination is associated with toxicity effects. Hence, anaesthetic potentials of lignocaine, lignocaine-adrenaline, fruit and stem-bark aqueous extract of Annona muricata were comparatively studied during castration in Nigerian indigenous dogs. Twelve adult dogs of about 1.00 ± 0.00-year-old and weighing 8.8 ± 0.4 kg divided into four groups of three each were used. The four groups were administered 2% lignocaine, lignocaine-adrenaline, fruit and stem-bark aqueous extracts each, at a dose of, 7.5 mg/kg each, by infiltration on the scrotal sac. After loss of sensation, ochidectomy was carried out. Time of onset and duration of anaesthesia were significantly higher (p < 0.05) in stem bark and fruit extract groups as compared to lignocaine and lignocaine-adrenaline groups. More so duration of anaesthesia was higher in lignocaine-adrenaline as compared to adrenaline. The findings have shown that lignocaine and lignocaine-adrenaline could increase whereas stem bark and fruit extract could decrease respiratory rate, respectively. Highest duration of anaesthesia was observed in stem- bark extract anaesthetized dogs followed by fruit extract treated group in comparison with lignocaine-adrenaline and lignocaine treated groups. Time of onset of anaesthesia was longest in fruit extract treated group and shortest in lignocaine and lignocaine-adrenaline treated groups respectively. Lignocaine and lignocaine/adrenaline increased and decreased haematological parameters, respectively. Lignocaine, lignocaine-adrenaline and the extracts altered biochemical parameters. Hence, Annona muricata could serve as potent local anaesthetic agent.

Abstract: Abstract Emergence of antiviral drug resistance in influenza virus remains a major public health concern worldwide. Nowadays, different herbs receive renewed attention because of their enormous antiviral potential. In this study, we investigated the antiviral activity of Camellia sinensis, Persicaria hydropiper, Persicaria orientale, Persicaria lapathifolia, Persicaria stagnina, Mucuna pruriens and Chenopodium album against different influenza strains using both in vitro and in silico approaches. Antiviral effect of plant extracts was evaluated by cytopathic effect (CPE) inhibition assay on influenza infected MDCK (Madin Darby Canine Kidney) cell line. Later, the herb demonstrating antiviral activity was virtually screened for their available bioactive compounds and multiple in silico tools were performed to prioritize and establish these compounds as potential inhibitor. The methanol, but not the n-hexane and ethyl acetate extracts of C. sinensis, P. hydropiper, M. pruriens and C. album exhibited anti-influenza effect with EC50 values within 32–46 µg/ml. Importantly, the extracts remained effective against both amantadine-resistant and -sensitive influenza isolates. The molecular docking analysis showed that flavonoids, steroid and derivatives had strong binding affinity to the target proteins which may remain responsible for the anti-influenza characteristics of plant extracts. Pharmacokinetic properties, bioavailability and drug-likeness score revealed that ferulic acid, sinapic acid, campesterol, cryptomeridiol, eupatin and genistein could be attractive leads as potential influenza inhibitors. Taken together, the botanical ingredients of these herbs could be used as valuable candidates for developing novel therapeutics to control influenza related illnesses.

Abstract: Diseases of the kidney and urinary tract including urolithiasis became a major cause of global illness and death. There are approximately 7.85 million people suffering from chronic renal failure in India. Further, urolithiasis is also a common global phenomenon of renal disorders. Unani Medicine (UM) is a famous kind of conventional medicine practised throughout South Asia that relies on the ancient conventional medicinal systems of India, Egypt, China, Iraq, Syria, and Persia. Berberis vulgaris (BV), Physalis alkekengi (PA) and Boswellia serrata (BS) are very common drugs against urinary disorders in Unani medicine. But, to establish their role to treat in urinary disorders are still obscure. HPTLC fingerprints confirmed the presence of signature compounds according to pharmacopeia. Polyphenolic acids and flavonoids in the test drugs have been quantified by HPLC. BS showed maximum inhibitory action on DPPH (2,2-diphenyl-1-picrylhydrazyl) radicals, nitric oxide and superoxide scavenging than other two test drugs, while, PA have highest hydrogen peroxide scavenging action. In diuretic activity, maximum urination occurred in BS group than other two test drugs BV and PA. The highest excretion of sodium–potassium ratio was noted in PA groups followed by BS and BV. BV showed maximum efficacy in crystal formation in test tubes followed by BS and PA. Graphical abstract

Abstract: Abstract An ethnobotanical survey was conducted in Katsina state, Northern Nigeria to document medicinal plants commonly used by lactating mothers to boost breast milk production. Two hundred and forty (240) respondents made up of (120) nursing mothers, (60) herbalists and (60) traditional birth attendants were interviewed. Ethnobotanical data was obtained using the structured questionnaire method. Standard procedures were followed to analyse the phyto-chemical, proximate, mineral concentrations and chemical composition of the ethanolic extract of the most cited plants. Forty (40) plant species belonging to 38 genera distributed among 24 families are used as galactagogues in Katsina state, Nigeria. All the plant samples contained alkaloids, cardiac glycosides, flavonoids, saponins, tannins and terpenoids. Anthraquinones were found to be absent in Andropogon gayanus, Moringa oleifera and Pennisetum glaucum while phytosterol was absent in Pennisetum glaucum and Vernonia amygdalina. They were also found to contain nutrient compositions in varying amounts. Crotalaria retusa had the highest moisture (12.80%), crude lipid (13.50%) and crude fibre (21.76%) content. Momordica balsamina has the highest ash (13.76%) content. Pennisetum glaucum had the highest carbohydrate content (76.19%) and energy content (364.95%). Mineral analysis revealed that Andropogon gayanus, Momordica balsamina and Vernonia amygdalina showed equal phosphorus (0.3 ppm) contents. Crotalaria retusa showed the highest chromium (2.59 ppm) and copper (1.31 ppm) content. GC/MS analysis revealed that Momordica balsamina contained 99 phytoconstituents. With only 9,12-Octadecadienoic acid (Z,Z)- identified as the only phytoconstituents showing phytoestrogen activity. The indigenous knowledge about lactating mothers in Katsina state, Nigeria used medicinal plants to boost breast milk production is documented.

Due to the frequent use of its stem bark and roots in traditional phytotherapy, the species is getting threatened in its distributional ranges. The current review was sought to document information on the ethnobotany, phytochemicals and pharmacology of different parts of A. coriaria, so as to highlight the gaps thereof for future studies. Data retrieved revealed that medicinal uses of A. coriaria have been reported for both human and veterinary ailments. Though the bark is the most commonly used, different parts of the plant are used to prepare herbal remedies for treatment of malignancies, odontological, dermatological, respiratory, gastrointestinal, reproductive, central nervous system infections/conditions and ailments. Preliminary phytochemical screening has indicated the presence of saponins, tannins, alkaloids, flavonoids, phenols, terpenes, cardiac glycosides and steroids as the major secondary metabolites in the stem bark and leaves. Like for other Albizia species, at least six triterpenoidal saponins have been characterized in organic extracts of A. coriaria stem bark and roots. Extracts and some pure compounds from A. coriaria stem bark, leaves and roots have exhibited antiproliferative (cytotoxic), antiplasmodial, molluscicidal, antigiardial, antioxidant, anti-inflammatory and antimicrobial activities. Further research should evaluate pharmacological properties such as antisnake venom, aphrodisiac, antiviral and antimycobacterial activities of the different parts of A. coriaria claimed in traditional folklore. In-depth studies on the pharmacokinetics, in vivo and clinical research utilizing extracts and isolated compounds from A. coriaria are required.
