Introduction: Lung cancer remains the leading cause of cancer death worldwide, so research is ongoing to discover new therapeutics, such as plant-derived bioactive compounds. For example, Sinensetin, a plant-derived polymethoxylated flavonoid, and Imperatorin, a natural furanocoumarin, have anti-cancer properties. This study assessed the effects of sinensetin and imperatorin separately and in combination on A-549 lung cancer cell viability. Method: The A-549 lung cancer cell line was treated with sinensetin (60 μM), imperatorin (30 M), or a combination of both compounds (Sin:Imp 30:30 μM; 50:50 μM and 60:30 μM) for 48 hours. Cell viability was then assessed using the 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide (MTT) assay and apoptosis was determined using fluorescein isothiocyanate (FITC) Annexin-V/Propidium iodide staining. Results: The combination treatment of Sin:Imp 50:50 and Sin:Imp 60:30 μM reduced cell viability more than the individual treatment of sinensetin and imperatorin, with the lowest cell viability observed for the combination treatment of Sin:Imp 50:50 μM. Likewise, the combination treatment of Sin:Imp 50:50 μM induced the most apoptosis compared to individual treatment. Conclusion: Sinensetin and imperatorin can decrease A-549 lung cancer cell viability and are potent apoptotic inducers, especially when they are used in combination, therefore they are potential lung cancer therapeutics.

This study aims to investigate the potential of sinensetin, a compound found in the Cat{\textquoteright}s Whiskers plant (Orthosiphon aristatus), as an inhibitor in inhibiting uric acid through its interaction with ATP Binding Cassette Sub-Family G Member 2 (ABCG2). The in-silico approach was employed using software tools such as Pymol, PyRx, Protein Plus, and Lepinski Rule. The results of molecular docking analysis using PyRx demonstrated significant interactions between sinensetin and ABCG2, with Binding Affinity values of -6.8, -6.6, and -6.6, and RMSD values of 0, 0.785, and 1.379. The analysis using Protein Plus confirmed the interaction between sinensetin and ABCG2, supporting the previous docking findings. Furthermore, the evaluation of pharmacokinetic parameters using the Lepinski Rule of Five revealed that sinensetin meets the criteria as a potential drug compound, with a molecular weight of 372, no hydrogen bond donors, seven hydrogen bond acceptors, a log P value of 3.345, and a molar reactivity of 98.5. This research provides new insights into the development of uric acid therapy through an in-silico approach, and these findings can serve as a basis for further research involving in vitro and in vivo validation.

Background: Diabetes mellitus (DM) is a complex chronic disease with hyperglycemia, which is glucose levels above normal whose number of sufferers is increasing. By inhibiting the human maltase-glucoamylase enzyme which is included in the starch-digestion pathway are used to delay glucose production and thus aid in the treatment of type II diabetes. Aims and Methods: To analyze the potential of mangostin derivatives (alpha-mangostin, betamangostin, gamma-mangostin) and sinensetin as anti-diabetes through ADMET prediction and in silico tests against human maltase-glucoamylase targets using the docking method with miglitol was used as a control. Result: The ligands ɑ, β, γ-mangostin and sinensetin have good interactions with macromolecules and form hydrogen bonds also van der Waals on the macromolecule active side of human maltase-glucoamylase. Conclusion: The ADMET of mangostin derivatives (ɑ, β, and γ), and sinensetin can be predicted by the pkCSM online tool, and they showed good affinity on maltase-glucoamylase target compared to standard drugs like miglitol.

Introduction: Imperata cylindrica root methanol extract harvested from Kendari had anti-hypertensive activity stated in a study on hypertension rat models at the doses 60 and 90 mg/kg-bw. The extract also contained phenolic compound 1.53\% (GAE) and flavonoid 1.17\% (QE) and had antioxidant activity IC50 0.32 mg/mL. Aim of the study was to determine the active secondary metabolites in the extract. Materials and Method: Sinensetin and imperatorin in the extract were separated on silica gel 60 column, eluted with a gradient eluent system as follows (1) n-hexane- ethyl acetate (3:7); (2) n-hexane {\textendash} ethyl acetate (2:8); (3) ethyl acetate -MeOH (8:2), and (4) methanol. Imperatorin and sinensetin in fractions were identified and quantified by HPLC method with column LiChroCART 250-4,6 RP 18E, isocratic mobile phases with the composition of mixture as follows, 0.1\% formic acid, acetonitrile and methanol (40:50:10) respectively, and at temperature 400 C. The total tannin was determined by spectrophotometry method with Fe(III) chloride and 1.10-Phenanthroline at wave length 510 nm. Results: Imperatorin and sinensetin were identified in fractions 5 to 9. The concentrations of sinensetin and imperatorin in Imperata cylindrica root methanol extract were of 32.348 and 37.014 mg/kg extract, respectively. The total tannin content was 1.06 \% (w/w) (TAE). Conclusion: Imperata cylindrica root methanol extract from Kendari had active phytoconstituents, namely sinensetin, imperatorin, and tannin.
