Methods: Molecular docking as a protease inhibitor of SARS-CoV-2 was carried using computational software Molegro Virtual Docker (MVD); computational docking was carried using receptors with Protein Data Bank (PDB) were also used to compare the affinity strength of the test compounds against the protease receptor (code of 5R81). The compounds of Cymbopogon nardus were optimized before docking using ChemDraw and minimized energy using Chem3D. Visualization of the docking result by using Discovery Studio and pkCSM was utilized to perform a pharmacokinetic and toxicological analysis (ADMET). Results: The result showed geranyl acetate, elemol, citronellal, and citronellyl acetate compounds from Cymbopogon nardus has a rerank score more negative than native ligand from 5R81 receptor as a protease inhibitor of SARS-CoV-2. Conclusion: Cymbopogon nardus can be developed as an antivirus with the mechanism of a protease inhibitor of SARS-CoV-2 candidates after further experimental tests.

Background and Aim An antimicrobial delivery in the form of surface-modified lectin of lipid nanoparticles was proposed to improve cellular accumulation. ArtinM, an active toll-like receptor 2 (TLR2) agonist lectin isolated from cempedak ( Arthocarpus integrifolia) seeds, was selected to induce cellular engulfment of nanoparticles within infected host cells. Materials and Methods Lipid nanoparticles were prepared using the emulsification technique before electrostatic adsorption of artinM. The formula comprising of rifampicin, soy phospholipid, and polysorbate 80 was optimized by Box-Behnken design to produce the desired particle size, entrapment efficiency, and drug loading. The optimum formula was characterized for morphology, in vitro release, and cellular transport. Results and Discussion Soy phospholipid showed a profound effect on controlling drug loading and entrapment efficiency. Owing to its surface activity, polysorbate 80 contributed significantly to reduce particle size; however, a higher ratio to lipid concentration resulted in a decrease of rifampicin encapsulation. The adsorption of artinM on the surface of nanoparticles was accomplished by electrostatic binding at pH 4, where this process maintained the stability of encapsulated rifampicin. A high proportion of artinM adsorbed on the surface of the nanoparticles shown by haemagglutination assay, zeta potential measurement, and transmission electron microscopy imaging. Cellular uptake revealed by confocal microscopy showed the success in transporting Nile-red labelled nanoparticles across fibroblast cells. Conclusion The delivery system of nanoparticles bearing artinM becomes a potential platform technology for antibiotic targeting in the treatment of life-threatening chronic diseases caused by intracellular infections.

Objective: The purpose of this study was to obtain the best formulation of red ginger oil balm that can be used for aromatherapy as an analgesic. Methods: The red ginger plant in Steam-water distillation produces red ginger oil. Red ginger oil is tested for quality and formulated. The best formulation result is then tested for product quality. Results: The result of red ginger oil quality parameters is obtained in accordance with the literature. As the result of the hedonic test, formula 4 was chosen to be the best formula. The result of the total plate number is<`10 CFU/ml. The result of the identification of Staphylococcus aureus and Pseudomonas aeruginosa is negative.

Conclusion: The Essentials oils from Cymbopogon nardus have not effectively suppressed the Rheumatoid Arthritis pathway through inhibition of TNF-α, JAK1/2, JAK3, PAD4, and DHFR which can serve as potential lead compounds for the development of new drugs for the treatment of Rheumatoid Arthritis.

Temulawak rhizome (Curcuma xanthorrhiza R.) is efficacious as antidiabetic because it has curcuminoid compounds. The aim of the research was to make, characterize, and optimize the nanoparticle formula of dried temulawak rhizome extract. The rhizomes were macerated using 96% ethanol. The curcuminoid content of the thick extract was determined using a spectrophotometer and dried extract using a spray dryer. The dried extract was formulated into nanosuspension using ionic gelation method by mixing a concentration of 0.1–0.5% dried extract with a mixture of 0.2% chitosan and 0.1% sodium tripolyphosphate in a 2:1–5:1 ratio. Characterization was carried out including: particle morphology, particle size, polydispersity index, zeta potential, and entrapment efficiency. Response data were analyzed by factorial 22 design using Minitab18 software to determine the optimum formula. The concentration of curcuminoids in the thick extract was 15.96%. The morphology of the nanosuspension was spherical, with a particle size of 114.7–399.3 nm, a polydispersity index of 0.429–0.597, a zeta potential of 35.1–48.6 mV, and an entrapment efficiency of 61.08–73.37%. The optimum formula was obtained with a composition of 0.44% extract and chitosan: Na-TPP (2:1) with a desirability value, d= 0.8984. It can be concluded that the factorial design of 22 can be used to determine the optimum formula for dried extract of temulawak rhizome using the ionic gelation method.
