Cervical cancer is the fourth most common female cancer worldwide and results in over 300000 deaths globally. Given that HPV prophylactic vaccines do not exert a therapeutic effect in individuals previously infected, it is unlikely that HPV-associated cancers will be eradicated in the coming years. Therefore, there is an emerging need for the development of anti-HPV drugs. The purpose of this study is to find out Monascus sp. as cervical anticancer using molecular docking and dynamics methods. The results of docked with AutodockTools were visualized with Pymol, analyzed the effectiveness using the Ramachandran plot. The docking results show that there are 2 pigments that have lower G than raloxifen in estrogen receptor beta with the lowest G indicated by the pigment Monascin and Ankaflavin, which is -6.94 kcal/mol with Ki value of 39.49 nM and -6.22 kcal/mol with Ki value of 27.78 nM. The results of molecular dynamics, Ankaflavin and Monascin have good stability at estrogen receptor beta because the outlier area has a value 11.722% and 10.256%. And the amino acid residues in the most preferred area were 68.864% and 70.330%. In addition, Monascopyridine B and Monascuspiloin pigments showed good and stable results at the EGFR receptor because the outlier areas were 14.692% and 10.623%. And the amino acid residues in the most-favored region were 65.403% and 73.260%. Based on the results of this study, we predict that Ankaflavin, Monascin, Monascopyridine B and Monascuspiloin can be used as new cervical anticancer candidates after validated with in vitro and in vivo tests.

SARS-CoV-2 causes about 66% of China’s Wuhan market workers to experience fever, dry cough, and fatigue. Black cumin (Nigella sativa) is a plant with many benefits to cure many illnesses like hypertension, headache, infection, and inflammation. This study aimed to investigate the inhibition by compounds belonging to the Alkaloid group from Black Cumin Seed to inhibit PLpro activity as a target for SARS-CoV-2. The study used five alkaloid compounds ((2E,4E)-Decadienal, (2E,4Z)-Decadienal, Nigellicine, Nigellidine, and Nigellimine) from the Black cumin seed and a PLpro SARS-CoV-2 receptor (PDB ID: 6WX4). The methods used are ligand and receptor preparation, grid box validation, molecular docking, 2D and 3D visualisation, and data analysis using Gibbs free energy, type of interaction, and contact of amino acid residues data. This study used YASARA structure and BIOVIA Discovery Studio. The results showed that Nigellidine has the highest Gibbs free energy with a -2.67 kcal/mol score, higher than VIR251. PLpro has a catalytic triad at Cys111, His272, and Asp286 residues, the compound that binds to the active site is Nigellicine found at amino acid Cys111 with Pi-Sulfur.

Various medications are being developed using natural products, particularly those resulting from medicinal plants. So, the screening and quantity analysis of phytochemicals in the methanol leaf extract of Erlangea tomentosa was looked at to find out what chemicals in the plant were responsible for its biological activity. Ten different phytochemicals, such as alkaloids, glycosides, cardiac glycosides, flavonoids, saponins, coumarins, steroids, terpenoids, phenols, and tannins, were found by the analysis. Glycosides and cardiac glycosides were below the limits, and neither phlobatannins nor anthraquinones were found. Quantitative phytochemical analysis showed that there were 3.38g of alkaloids, 2.19g of tannins, 1.81g of flavonoids, and 0.31g of saponins. The concentrations of standard solutions per 100g of crude sample were used to estimate all the results of the tests.

The purpose of this research was to design an implant for a ciprofloxacin-based drug delivery system by combining bovine hydroxyapatite and collagen with genipin as the crosslinking agent. The production of ciprofloxacin implants using bovine hydroxyapatite:collagen blend (70:30). In addition, this synthetic preparation was made using three various concentrations of genipin (0.6, 0.8, and 1.0%). The pellets were created by compressing the implants. The tablets are cylindrical with a diameter of 4.0 mm and a weight of 100.0 mg. Ciprofloxacin cultures were characterized for swelling rate, porosity, density, compressive strength, morphology (SEM), dose, and drug release in vitro. The addition of genipin as a crosslinking agent may maintain ciprofloxacin release consistent with in vitro therapeutic levels of ciprofloxacin. These results are supported by compressive strength data, where the addition of genipin concentrations induces higher implant stiffness and scanning electron microscopy photomicrographs reveal small pore sizes and BHA adhere to collagen fibers so that ciprofloxacin is completely dispersed in the implant after cross-linking with genipin. As a drug delivery system for osteomyelitis, it can be concluded that the use of genipin as a cross-linking agent can sustain ciprofloxacin release commensurate with in vitro therapeutic levels of ciprofloxacin for 30 days.

Platelet aggregation has the potential to form thrombi and result in cardiovascular system diseases such as myocardial infarction and ischemic stroke - one of the leading causes of death globally. Traditionally, people use binahong leaves as blood thinners. Therefore, this study aims to obtain scientific data on the efficacy of binahong leaf as antithrombotic. The efficacy test was carried out on male Swiss-Webster mice. The results showed that the ethanol extract of binahong leaves at doses of 50 (BLEE50) and 100 mg/kg bw (BLEE100) could increase bleeding time on H7 (7.61±1.79% and 3.72±1.76% vs 1.08±0.90%) and H14 (13.81±4.42% and 5.06±2.30% vs 1.66±1.09%) and coagulation time at H7 (5.01±1.36% and 4.18±1.67% vs 1.38±1.08%) and at H14 (7.92±1.97% and 7.19±1.96% vs 1.70±1.10%) significantly (p<0.05). The two doses of BLEE were formulated in the form of nanoemulsions with the Self Nano Emulsifying Drug Delivery System (NBLEE50 and NBLEE100) were also able to prolong bleeding time and coagulation time significantly (p<0.01) but only NBLEE50 prolonged bleeding time (p<0.05) significantly against BLEE50. In the test of the anti-platelet aggregation effect with ADP as an inducer, both doses of BLEE and the nanoemulsion preparation (NBLEE) could significantly (p<0.01) inhibit platelet aggregation with a percentage of inhibition >70% which was not different from the standard (acetylsalicylic acid). In the antioxidant effect test using the DPPH method, BLEE has an IC50 = 66.08?g/mL which is classified as a strong antioxidant. Both doses of BLEE and its NBLEE could significantly (p<0.01) inhibit lipid peroxidation in plasma and liver and NO radicals formation. BLEE50 can significantly (p<0.05) reduce mean platelet volume (6.05±0.24fL vs 6.55±0.34fL) and platelet distribution width (8.52±0.36% vs 9.25±0.42%). Based on those results, BLEE has the potential to be used as an antiplatelet aggregation and antioxidant.

BLEE50 can significantly (p<0.05) reduce mean platelet volume (6.05±0.24fL vs 6.55±0.34fL) and platelet distribution width (8.52±0.36% vs 9.25±0.42%). Based on those results, BLEE has the potential to be used as an antiplatelet aggregation and antioxidant.","PeriodicalId":17494,"journal":{"name":"Journal of Tropical Pharmacy and Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47535745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study aimed to determine genistein content and tyrosinase inhibition activity of 70% ethanolic and ethyl acetate extracts of edamame (Glycine max) with an extraction time of 15, 30, and 60 minutes. Extraction was performed using the ultrasonication method. Determination of genistein content was carried out using TLC-densitometry. Furthermore, all samples were tested for their tyrosinase inhibition activity using the spectrophotometric assay. Ethyl acetate extract with 60 min of extraction time exhibited the highest extraction yield (6.414% w/w), the highest genistein content (0.169 ± 0.007% w/w), and the highest tyrosinase inhibition activity (IC50 = 72.420 ± 0.550 µg/mL). It was known that the genistein content of 70% ethanolic and ethyl acetate extracts affected tyrosinase inhibition activity with correlation coefficient (r) values of 0.9973 and 0.9826, respectively. G. max was suggested as a tyrosinase inhibitor agent from natural sources for skin whitening product development due to its isoflavones content, mainly genistein.

Psoralea corylifolia has gained much attention, particularly in the cosmetic industry for the past few years owing to promising pharmacological activities of its metabolites. Seeds of P. corylifolia are the main source of bakuchiol, a meroterpene compound that is extensively harnessed in numerous skincare products. Furanocoumarins, psoralen and isopsoralen are other metabolites mainly from P. corylifolia seeds and known for their antipsoriatic activity. Moreover, various studies have reported several classes of secondary metabolites from this plant possessing diverse biological activities. This article highlights recent updates on P. corylifolia phytoconstituents and their promising pharmacological activities based on scientific publications during the last 10 years (2011-2021). The literature search was carried out through scientific-based websites and databases such as Google Scholar, NCBI, and PubMed. This paper included sixty-three bioactive metabolites reported in the last 10 years, belonging to the group of flavonoids, meroterpenes, furanocoumarins, coumestans, steroid and phenolic compounds. These phytoconstituents displayed a broad range of bioactivities including anti-inflammatory, antibacterial, antidiabetic, controlling obesity, hepatoprotective and cytotoxicity. Keywords: Bakuchiol, pharmacological activities, Psoralea corylifolia, bioactive metabolites.
