AIM: The hepatoprotective activities of  bioactive compounds Pirdot were investigated in vivo and in silico. METHODS: In this study, the completely randomized design non-factorial was experimentally to assess the value of SGPT and SGOT and twenty four adult male rats were divided into four groups : group G0, control group; group G1, a treated group received 0.1 ml sheep red blood cell; group G2, a treated group received 500 mg ethanol extract Pirdot; group G3, a group treated received 500 mg ethanol extract Pirdot and 0,1 ml sheep red blood cell. On thirty one days of treatment, the blood of all rats group were taken to value SGPT and SGOT using DiaLab kit. Furthermore, the molecular docking study was done to analyse molecular interaction that COX-2 and  TNF-α were the primary target protein of bioactive compounds of Pirdot associated with hepatoprotective activities. In addition, it tends to be the target of non-steroidal anti-inflammatory drugs such as Ibuprofen. RESULTS: The results show SGOT and SGPT value significantly [p<0.05] decreased on Group G2 and G3. Moreover, the bioactive compounds of Pirdot, such as Pomolic acid and Ursolic acid tend to be the potential compound on liver protection. Moreover, Pomolic acid has a good binding affinity -14.6 kcal mol-1 with COX-2 Protein and the binding affinity of cis-3-O-p-hydroxycinnamoyl Ursolic acid was -15.1 kcal mol-1 associated with TNF-α Protein. CONLUSION:  Pirdot Leaves (Saurauia vulcani Korth.)  Ethanol Extract showed Hepatoprotective activity in rats (Rattus norvegicus). Molecular docking approach showed that pomolic acid has a good binding affinity with COX-2 Protein and TNF-α Protein.

AbstractInflammation, a protective response against infection and injury, involves a variety of biological processes. Sophorae Flavescentis (Kushen) is a promising Traditional Chinese Medicine (TCM) for treating inflammation, but the pharmacological mechanism of Kushen’s anti-inflammatory effect has not been fully elucidated. The bioactive compounds, predicted targets, and inflammation-related targets of Kushen were obtained from open source databases. The “Component-Target” network and protein–protein interaction (PPI) network were constructed, and hub genes were screened out by topological analysis. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed on genes in the PPI network. Furthermore, nitric oxide (NO) production analysis, RT-PCR, and western blot were performed to detect the mRNA and protein expression of hub genes in LPS-induced RAW264.7 cells. An immunofluorescence assay found that NF-κB p65 is translocated. A total of 24 bioactive compounds, 465 predicted targets, and 433 inflammation-related targets were identified and used to construct “Component-Targets” and PPI networks. Then, the five hub genes with the highest values-IL-6, IL-1β, VEGFA, TNF-α, and PTGS2 (COX-2)- were screened out. Enrichment analysis results suggested mainly involved in the NF-κB signaling pathway. Moreover, experiments were performed to verify the predicted results. Kushen may mediate inflammation mainly through the IL-6, IL-1β, VEGFA, TNF-α, and PTGS2 (COX-2), and the NF-κB signaling pathways. This finding will provide clinical guidance for further research on the use of Kushen to treat inflammation.

Rosemary (Rosmarinus officinalis L.) is a Mediterranean medicinal and aromatic plant widely used due to valuable bioactive compounds (BACs) and aromas. The aim of the study was to evaluate the extraction of intracellular compounds from rosemary combining experimental procedure by means of high voltage electrical discharge (HVED), with a theoretical approach using two computational simulation methods: conductor-like screening model for real solvents and Hansen solubility parameters. The optimal HVED parameters were as follows: frequency 100 Hz, pulse width 400 ns, gap between electrodes 15 mm, liquid to solid ratio 50 mL/g, voltage 15 and 20 kV for argon, and 20 and 25 kV for nitrogen gas. Green solvents were used, water and ethanol (25% and 50%). The comparison was done with modified conventional extraction (CE) extracted by magnetic stirring and physicochemical analyses of obtained extracts were done. Results showed that HVED extracts in average 2.13-times higher total phenol content compared to CE. Furthermore, nitrogen, longer treatment time and higher voltage enhanced higher yields in HVED extraction. HVED was confirmed to have a high potential for extraction of BACs from rosemary. The computational stimulation methods were confirmed by experimental study, ethanol had higher potential of solubility of BACs and aromas from rosemary compared to water.

Abstract. Sorghum bicolor L. Moench is widely grown all over the world for food and feed. The effects of sorghum extracts on general inflammation have been previously studied, but its anti-vascular inflammatory effects are unknown. Therefore, this study investigated the anti-vascular inflammation effects of sorghum extract (SBE) and fermented extract of sorghum (fSBE) on human aortic smooth muscle cells (HASMCs). After the cytotoxicity test of the sorghum extract, a series of experiments were conducted. The inhibition effects of SBE and fSBE on the inflammatory response and adhesion molecule expression were measured using treatment with tumor necrosis factor-α (TNF-α), a crucial promoter for the development of atherosclerotic lesions, on HASMCs. After TNF-α (10 ng/mL) treatment for 2 h, then SBE and fSBE (100 and 200 μg/mL) were applied for 12h. Western blotting analysis showed that the expression of vascular cell adhesion molecule-1 (VCAM-1) (2.4-fold) and cyclooxygenase-2 (COX-2) (6.7-fold) decreased, and heme oxygenase-1 (HO-1) (3.5-fold) increased compared to the TNF-α control when treated with 200 μg/mL fSBE (P<0.05). In addition, the fSBE significantly increased the expression of HO-1 and significantly decreased the expression of VCAM-1 and COX-2 compared to the TNF-α control in mRNA level (P<0.05). These reasons of results might be due to the increased concentrations of procyanidin B1 (about 6-fold) and C1 (about 30-fold) produced through fermentation with Aspergillus oryzae NK for 48 h, at 37 °C. Overall, the results demonstrated that fSBE enhanced the inhibition of the inflammatory response and adherent molecule expression in HASMCs.

A banana apresenta elevada suscetibilidade a doenças como as podridões que diminuem o tempo de prateleira do fruto. Uma das formas de controlar as doenças seria a utilização de métodos alternativos como os extratos de plantas medicinais. Assim, o objetivo deste estudo foi verificar a ação de formulados de alecrim (Rosmarinus officinalis L.) pó e líquido no controle de antracnose causada pelo fungo Colletotrichum musae (Berk & Curt.) Von Arx. e na maturação de banana ‘Nanicão’ em pós-colheita. Foram utilizadas as concentrações 0%; 0,25%; 0,5%; 1%; 1,5% e 2% do pó solúvel de extrato de alecrim diluído em água destilada, e as concentrações 0%; 0,5%; 1%; 2%; 4% e 6% do formulado aquoso contendo 21% de resíduo seco de alecrim diluído em água destilada. Foi realizada a mensuração da área de cada fruto e avaliada a severidade e a maturação a partir de porcentagem de área dos frutos, sendo os resultados utilizados para calcular a área abaixo da curva de progresso da doença (AACPD) e a porcentagem de maturação dos frutos. Realizou-se analise de regressão a partir dos dados obtidos e pode-se verificar que para o formulado de alecrim em pó a AACPD reduziu mais de 29% e para a maturação a redução foi de 21,72%. Para o formulado líquido a redução foi de 14,31% para AACPD e cerca de 10% para maturação. Assim, concluiu-se que houve eficiência por parte dos formulados de alecrim no controle da antracnose e no aumento da vida de prateleira da banana ‘Nanicão’.
