COVID-19 has become a global pandemic since 2020. The search for promising drugs based on the abundant herbal ingredients in Indonesia is one of the breakthroughs. Curcumin is a chemical compound with various potentials such as antioxidant, anti-inflammatory and antiviral. We conducted a molecular docking analysis to determine the potential of curcumin against SARS-CoV-2 non-structural and structural proteins, such as the main protease and spike protein. This study used the compound of curcumin (PubChem CID: 969516) from Curcuma longa L. or turmeric and two Indonesian SARS-CoV-2 isolates that have been deposited in the GISAID database (hCoV-19/Indonesia/JI-PNF-217315/2021 - EPI_ ISL_12777089 or lineage B.1.617.2 and hCoV-19/Indonesia/JI-PNF-211373/2021 - EPI_ISL_6425649 or lineage B.1.470). In addition, we used molnupiravir (PubChem CID: 145996610) as a drug control. We performed molecular docking analysis with PyRx software 0.9.9 (academic license) and visualization of molecular docking results with PyMOL software 2.5.4 (academic license). The results of this study found that curcumin had good potential against main protease and spike protein compared to the drug (control). In summary, we suggested that curcumin is a potential drug candidate against SARS-CoV-2. However, there is a need for future wet laboratory-based pre-clinical research such as in vitro and in vivo.

The traditional medicine has been used in Indonesia since the days of the Ancient Mataram Kingdom (about 12 centuries ago). Indonesia is rich in medicinal plants. For this reason, it is necessary to inform the broader community regarding medicinal plants in Indonesia that have the potential as antigout. The prevalence of gout in Indonesia is in the range of 1.6-13.6 per 100,000 people and will increase with age. There are 25 species of Indonesian plants that have more than 50\% xanthine oxidase (XO) enzyme inhibitory activity. XO is responsible for catalyzing hypoxanthine to xanthine then producing uric acid, accompanied by the formation of reactive oxygen species (ROS) during catalysis. The magnitude of the inhibitory power to XO ranged from 50.00{\textpm}1.16\% to 97.53\%. The lowest inhibitory power of 50.00{\textpm}1.16\% was in Phaleria macrocarpa, while Orthosiphon aristatus had the highest inhibitory power of 97.53\%. The major compounds that inhibit xanthine oxidase are flavonoids. The structural similarity of flavonoids in rings A and C with xanthine as a substrate causes hydrophobic interactions, hydrogen bonds, and van der Waals forces between flavonoids and XO. It means that flavonoids bind to the XO active site, thereby preventing the formation of uric acid. The type of inhibitory kinetics that occurs between flavonoids and XO is competitive inhibition. Five plants with competitive inhibition kinetics against XO are Sida rhombifolia, Syzygium polyanthum, Cyperus rotundus, Ruellia tuberosa and Phaleria macrocarpa.

Graptophyllum pictum (L.) Griff., a shrubby stove plant, has been used traditionally to treat various diseases. This review summarizes the up-to-date data about its phytochemistry and pharmacological properties and provides a perspective and direction for future research. The phytochemical analysis of G. pictum revealed the presence of flavonoids, steroids, glycoside, tannins, saponin, chlorophyll, nontoxic alkaloid, and anthocyanin. Meanwhile, the pharmacological analysis revealed that this plant possessed various activities such as antimicrobial, immunomodulatory, antioxidant, anti-inflammation, anti-analgetic, woundhealing, anti-hemorrhoid, anti-diabetic, and estrogenic effects. However, most of its pharmacological activities were based on the crude extracts and the bioactive compounds responsible for the bioactivities have not been well identified. A further detailed investigation in phytochemistry to identify the bioactive compounds and to investigate the mechanism action of its bioactivities is required. Moreover, a toxicology study is also needed to develop a standardized formulation of G. pictum preparation and to fulfill the requirements of modern phytomedicine.

Introduction: Red macroalgae Acanthophora spicifera is commonly found in most parts of Indonesia coastal areas. However, information regarding their potential pharmaceutical uses remains largely unexplored. This study evaluates the antiproliferative activity of Acanthophora spicifera collected from Indonesian extracted with different solvents of ethanol and methanol. Methods: Cytotoxicity and antiproliferative activity of A. spicifera crude ethanol extract (AS-EtOH) and A. spicifera crude methanol extract (AM-MetOH) were evaluated with Lactate dehidrogenase (LDH) and Trypan blue exclusion assay in Human cervical cancer (HeLa) cells for 72h. Concentration of extracts treated in HeLa cells were 6.25 to 200 μg/mL. Viability staining with fluorescence stain Hoechst33342/PI was conducted to investigate apoptotic activity. Potential apoptotic activity of treatments was confirmed by DNA fragmentation assay. Results: AS-MetOH demonstrated high cytotoxicity in HeLa cells with IC50 of 127.3 {\textpm} 33.13 μg/mL. However, AS-EtOH IC50 values could not be determined in this study. Antiproliferative activity was highly significant in AS-MetOH treated cells as cell density was suppressed to 20 x 104 cells/mL compared to AS-EtOH (73 x 104 cells/mL) and untreated cells (83 x 104 cells/mL). Finally, apoptotic activity could be determined in AS-MetOH treated cells with increase PI fluorescence emitting cells and DNA fragmentation. On the other hand, apoptotic activity was not observable in AS-EtOH treated cells based on fluorescence viability staining and DNA fragmentation assay. Conclusion: Current results show methanol solvent as an effective solvent to promote potential pharmaceutical properties of macroalgae A. spicifera. Further advanced studies in a compound level from A. spicifera methanol fraction would be reasonable for development of macroalgae based anticancer agent.
