However, its utilization is still limited because its solubility in water is very low which results in low absorption by the skin, resulting in low bioavailability. In this case, to increase the potency of astaxanthin, this research was aimed at the formulation and characterization of astaxanthin nanoemulsions using polysorbate 80 and polyethyleneglycol 400 as a mixture of surfactants with a ratio of 7:1; 8:1 and 9:1 with the method of making a combination of low and high energy emulsification. The data obtained were analyzed using the Kruskal-Wallis test for data on the pH of the preparation and the efficiency of adsorption while the pH test during freeze-thaw stability was analyzed by the Wiloxon test. Based on the test results, it was found that the nanoemulsion preparation with the smix 9:1 formula is the most optimum formula among other formulas, which is to produce preparations with quite good characteristics organoleptically and give a light orange color appearance, clear, distinctive smell with a pH value that meets the SNI standard 16-164399-1996 with pH values ranging from 7.13 to 7.15 and based on the centrifugation test gave stable results and had particle size, polydispersity index and zeta potential values, respectively, 22.9 ± 9.4 nm, 0.435 and -21. ,4 mV and the value of entrapment efficiency ranges from 93.87% to 94.32%. However, the thermodynamic stability is not good enough.

The in situ gel dosage form is desired to overcome the poor bioavailability of conventional ciprofloxacin HCl eye drops on the market.

The government must guarantee to Muslim consumers that consumer goods or services circulating in the community are truly halal. The halal label itself will increase consumer confidence, expand the reach of the global halal food market, and increase the marketability of products in the market. Indonesia, which is predominantly Muslim, is considered a long extension in implementing HP until 2034. Different attitudes are shown by several countries with large non-Muslim majority populations but are very concerned about the implementation of HPC.

In this study, we investigated the effect of CSE-administration on tumor metastasis in a spontaneous tumor metastasis model using B16-BL6 cells, which is more clinical conditions. C57BL/6NCr mice were subcutaneously inoculated B16-BL6 cells into the footpad of the right rear leg. CSE was intraperitoneally administrated for 28 days from the day of inoculation. At 2 weeks after inoculation, the primary focus was excised. Subsequently, survival days of the mice were recorded to determine the effect of CSE-administration on spontaneous metastasis. The effect of CSE, α, β-unsaturated ketones, and aldehydes on B16-BL6 cell invasiveness were confirmed by matrigel invasion assay. Survival days of mice injected with 100% CSE was significantly shortened than that of control. B16-BL6 cell invasiveness was accelerated by the treatment with 0.1% CSE and 3 μM of crotonaldehyde. Intraperitoneal CSE-administration may progress spontaneous metastasis of B16-BL6 cells via enhancement of B16-BL6 cell invasiveness. As the cause, we found that crotonaldehyde contained in CSE may enhance the invasion ability of cancer cells.

The activity is strongly influenced by the type and position of the substituent group. By studying the structural pattern of quercetin and its impact on their binding affinity, the development of quercetin-based drugs can be optimized. The study aimed to determine the impact of 3D structure, type, and position of quercetin moiety on its activity against ROS-modulating enzymes that play a role in the induction and growth of ROS-induced cancer. The 23 natural quercetin derivatives were docked to 7 ROS-modulating enzymes using Autodock Vina to determine their binding affinity and interaction. The interaction stability was further studied through molecular dynamics simulation using the CABS Flex 2.0 server. Determination of crucial amino acid targets of the quercetin group was determined using DockFlin. Finally, the toxicity of each test ligand was determined using the pkCSM server. The highest binding affinity for SOD and NOX was produced by quercetin 3'-glucoside with the binding energy of -10.2 and -12.8 kcal/mol. Quercetin 3,4'-diglucoside had the highest binding affinity for CAT and GR at -11.5 and -10.5 kcal/mol, respectively. Routine produced the highest binding affinity at LOX (-10.9). Quercetin 3-O-xyloside and quercetin 3-O-rhamnoside-7-O-glucoside had the highest binding affinity in XO with a value of -10.4 kcal/mol. The glucose and prenyl groups are beneficial for quercetin in interacting with all ROS-modulating enzymes except XO. In contrast, the methoxy group negatively affects all interactions of quercetin with receptors. The perfect fit between the binding pocket and the 3D structure of the ligand greatly benefits the ligand in accessing more amino acids in the binding pocket.
