Bioinformatic and Molecular Interaction Studies Uncover That CCA-1.1 AND PGV-1 Differentially Target Mitotic Regulatory Protein and Have a Synergistic Effect against Leukemia Cells
Get PDFNumerous studies demonstrated CCA-1.1, the modified compound from PGV-1, inhibits tumor cells growth in breast and colorectal cancer. This time, we used bioinformatics and molecular interaction approaches to ascertain the potential CCA-1.1 activity target focusing on leukemia, along with the cytotoxic test in leukemia cells. Genomics data expression was collected through the COSMIC database by selecting gene sets from K562 cells as a model for chronic myelogenous leukemia (CML). We identified CCA-1.1 and PGV-1 predicted targets through SwissTargetPrediction. The overlapping genes between the CCA-1.1, PGV-1, and K562 cells were chosen for further analysis. We narrowed down the potential targets by using the list of genes involved in the cell cycle and mitosis collected through GeneCards. A molecular docking study was applied to determine the molecular interaction between CCA-1.1 or PGV-1 and the predicted protein target. We carried out a cytotoxic test using a trypan blue exclusion assay. We treated K562 cells with CCA-1.1 and PGV-1 in single and combination treatment to determine the half concentration of growth inhibitory (GI50) and combination index (CI) score. CCA-1.1 and PGV-1 shared similar predicted target genes in mitosis, and interestingly CCA-1.1 were mainly targeted in Aurora A (AURKA) in K562 cells with lower docking scores against the inhibitor in molecular docking analysis. Moreover, each compound exhibited an inhibitory effect similarly, and the co-treatment resulted in a synergistic effect in K562 cells. Collectively, we indicated that CCA-1.1 and PGV-1 possibly targeted mitosis in cell cycle progression, and along with their specific targets, led to their synergistic activity in CML. These findings should be validated through experimental studies to provide more pharmacological activities of CCA-1.1 to cure CML
The Effects of Media and Blanching Time on the Antioxidative Properties of Curcuma aeruginosa Roxb.
Get PDFBlack saffron (Curcuma aeruginosa Roxb.) belongs to the family of Zingiberaceae is one of rhizomes widely used as raw material in Indonesian Traditional Medicines. Black saffron (BS) contains some bioactive compounds responsible for certain biological activities including antioxidant. Blanching has been reported to increase the antioxidant activity of BS. This study aims to formulate BS containing high antioxidant activity. This research was performed by varying blanching medium (citric acid and aquadest) and blanching time (0; 2.5; 5; 7.5 and 10 min). The fabrication stage of BS powder included peeling, cleaning, blanching, slicing drying, grinding, and sieving. After that, the treated BS was analyzed for the antioxidant activity, total phenolic, total flavonoid, tannin, crude fiber, and water contents. BS powder subjected to blanching process showed better antioxidant activity than that without blanching process. Blanching using citric acid media 0.05% for 5 min showed the best antioxidant activities, as indicated by high contents of total phenolic, total flavonoid, and tannins. Powdered BS is potential to be used as materials to be applied as fortifying agents in food products
Favourable drug-lead pharmacokinetic features for designing gallic acid-standardized Syzygium polyanthum aqueous extract-based product
Get PDFIn this study, Syzygium polyanthum was standardized against gallic acid (GA), and a complete pharmacokinetic test was conducted using in vitro and in vivo models against this phytochemical. High-performance liquid chromatography showed that GA is a major phytochemical in aqueous extract of S. polyanthum. It exhibited a low equilibrium solubility and physiochemical stability at pH 2.0 and 7.4, but it deteriorated rapidly at pH 9.2. It showed low permeability toward Caco-2 intestinal absorption with eight times slower absorption in oral than intravenous administration. GA was unstable in mouse, rat, and dog plasma sera with in vitro half-lives (t1/2) of 60, 53, and 56 min, respectively, but was relatively stable in human plasma serum (t1/2 = 185 min). Approximately 5.6% of GA (10 µM) bound to the human plasma proteins. GA was stable in mouse, rat, dog, and human microsomal extracts with in vitro microsomal intrinsic clearance values of 72, 68, 6, and 22 µL/min/mg, respectively. GA selectively inhibited or stimulated the activity of the tested CYP450 enzymes. The in vivo oral bioavailability of GA was 54%, with short elimination half-life and a high volume of distribution. Thus, the mention pharmacokinetic features of GA must be considered during the development of GA-based products to yield the optimum dosage and pharmacological effect
Exploring the Potency of Jatropha Seed Meal (Jatropha curcas) as a Chemoprevention Agent through Metastatic Inhibition
Get PDFJatropha (Jatropha curcas) is often used as biodiesel because of the oil content in its seeds. The production of jatropha oil generates a byproduct in the form of jatropha seed meal, which contains compounds with cytotoxic activity and phorbol esters, as co-carcinogens and tumor promoters. Meanwhile, metastasis is one of the characteristics of cancer where the cells spread to another tissue. This study aimed to determine the potential of jatropha seed meal as a chemoprevention agent, particularly an antimetastatic one, under bioinformatic study and molecular docking. Genecards and DAVID were performed to explore the protein involved in the metastatic process and its gene ontology. The prediction target protein was caught by SwissTargetPrediction. Jatropha seed meal showed the presence of isoamericanol A, myricetin, daidzein, gallic acid, and rutin. There are 11 prediction target proteins correlated to metastatic in extracellular matrix components. Then we were docked to a protein involved in metastasis, matrix metalloproteinase (MMP)-9 (PDB ID: 6ESM) using MOE software. The docking score determined the interaction properties. The docking analysis revealed that isoamericanol A, daidzein, and myricetin exhibited better binding affinity than native ligands and other compounds. Moreover, based on our literature study, the jatropha seed meal contains isoamericanol A, rutin, myricetin, daidzein, and gallic acid, which present anticancer properties by inhibition of cell invasion and migration, cell cycle arrest induction, and suppression of the MMP-9 activity. Overall, jatropha seed meal has potential as an antimetastatic agent. A comprehensive study is needed to explore the possibility of developing it as a supportive agent in combination with a chemotherapeutic agent
