Objective: Andrographis paniculata has long been a traditional medicinal plant in Indonesia. This study is intended to evaluate the anti-pro-inflammatory cytokines of 98\% ethanol extract of A. paniculata by in vitro and in silico approaches. Inhibition of pro-inflammatory cytokines is also one of the therapies in treating COVID-19. Methods: The molecular docking approach was utilized as a first screening to evaluate the potential for suppression of macrophage cell activation; an ADMET prediction test was performed to determine the pharmacological, pharmacokinetic, and toxicity as a therapeutic target. TNF-α, IL-1{\ss}, and IL-6 levels were measured using an ELISA method to investigate anti-cytokine pro-inflammatory activity in LPS-induced RAW 264.7 macrophage cells. LC-MS/MS was used to identify additional metabolite compounds. Results: Ethanol extract containing particular metabolites 14-Deoxyandrographoside and 14-Deoxy-17-hydroxyandrographolide inhibited TNF-α and IL-1β by 100\% and IL-6 by 85.59\%, respectively. While compared to the Dexamethasone molecule as a positive control, preliminary screening and ADMET prediction for the metabolite compound 14-Deoxyandrographoside exhibited relatively high binding stability to the CD14 receptor by -7.5 kcal/mol and was safe against various ADMET indications. Conclusions: This study reveals that the compound 14-Deoxyandrographoside in pure ethanol extract is a potential anticytokine agent candidate for treating pro-inflammatory cytokines, including COVID-19 infection.

HIV sensory neuropathy (HIV-SN) is one among many complications that impair patients{\textquoteright} quality of life. Studies in Asian and African populations found that single nucleotide polymorphisms (SNPs) of calcium/ calmodulin-dependent protein kinase 2 (CAMKK2) influence the risk of HIV-SN. This study attempts to explain the influence of CAMKK2 mutations on HIV SN by studying bioinformatics interactions between CAMKK2, its mutants, and their inhibitors by molecular docking with AutoDock in order to observe their interactions with CAMKK2 inhibitors. Results showed that CAMKK2{\textquoteright}s binding energy with its native ligand (ATP) is stronger than the mutant variant of CAMKK2MT85 and CAMKK2MT363. Conversely, interaction between CAMKK2 and its inhibitors (KN-93, STO-609, and trifluoperazine) have the lowest mean binding energy compared to CAMKK2MT85 and CAMKK2MT363. This indicates that the mutant variants have weaker interactions with the native ligand and the inhibitors, therefore disrupting the normal function of CAMKK2, its interactions with the inhibitors, while increasing the likelihood of HIV-SN.

Background: The increasing incidence of multi-drug resistance among pathogens has propelled researchers to search for novel antimicrobial and anti-quorum sensing agents characterised by different mechanisms and high potency. Objective: The study aimed at investigating the antibacterial and antiquorum sensing properties of compounds from Erianthemum dregei and their molecular interactions with the target proteins. Methods: The methanolic leaf extract from E. dregei was evaluated for its chemical composition and antibacterial activity using gas chromatography-mass spectrophotometry (GC-MS) and micro-dilution method, respectively. The inhibition of violacein production in Chromobacterium violaceum (ATCC 07) was assayed as anti-quorum sensing activity using micro-dilution method. The molecular docking of the GC-MS ligands and penicillin-binding protein 2x (PDP2) and CviR was executed using AutoDock Vina. Results: The two volatile compounds namely phytol (93.58\%) and 3-tetradecyn-1-ol (6.42\%) were shown by GC-MS. The extract exhibited antibacterial activity against the selected bacterial strains with minimum inhibitory concentration (MIC) values ranging from 1.56 to 3.125 mg/mL. The maximum inhibition of violacein production of 53.93\% was observed at 1.56 mg/mL. Both compounds had docking scores of more than -6.0 kcal/mol against the target proteins. Conclusion: The results revealed that the extract is a potential source of antibacterial and anti-quorum sensing compounds and thus can have pharmacological applicability.

The two most significant as well as historically important non-steroidal and anti-inflammatory medications (NSAIDs), aspirin and ibuprofen, are frequently used to treat fever, pain, and inflammation. By blocking the activity of cyclooxygenase (COX), it can prevent the production of prostaglandin. In an effort to examine the physiochemical and biological properties of some heterocyclic amide derivatives and quantum mechanical computations have been used to analyze the compounds. To clarify the thermochemical, molecular orbital, and equilibrium geometrical features in the gas phase, density functional theory (DFT) with the B3LYP/6- 31G basis set has been used. Binding affinities and modes of heterocyclic amide analogs have been investigated on human cyclooxygenase (COX-1 and COX-2) proteins (6Y3C and 5F19) using molecular docking as well as nonbonding interactions. Results from geometry and thermochemical analysis support the chemical sustainability of all the structures. Most of the compounds exhibited a significant affinity for binding to the receptor protein (5F19) than the standard drugs aspirin and ibuprofen. The improved pharmacokinetic features of certain derivatives with reduced acute oral toxicity were revealed by ADMET prediction. Overall, four heterocyclic amide analogs 3-6 were found to be more efficient in inhibiting COX- 2 (5F19) than COX-1 (6Y3C), suggesting that they may be useful as COX-2-related inflammation drug candidates.

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.

Density functional theory (DFT) with the B3LYP/6-31G+ basis function has been used to elucidate the thermo-chemical, molecular orbital, and optimum geometrical aspects in the gas phase. Using molecular docking and non-bonding interactions, the binding affinities and behaviors of some heterocyclic aspirin analogs have been studied on human cyclooxygenase (COX-1 as well as COX-2) proteins (6Y3C and 5F19). The chemical stability of all structures is supported by geometry and thermo-chemical findings. In contrast to aspirin and ibuprofen, almost all tested analogs exhibited a substantial binding score to the receptor protein (5F19). The ADMET prediction revealed the enhanced pharmacokinetic properties of some derivatives with less acute oral toxicity. Overall, eight heterocyclic aspirin analogues 2-9 were shown to be more effective in inhibiting Cyclooxygenase-2 (5F19) than Cyclooxygenase-1 (6Y3C), indicating that they may be effective as COX-2-related inflammation therapeutic candidates.

Background: Malaria is a constantly challenging problem, notably in the Coronavirus Disease-19 (COVID-19) pandemic. The syndemic condition, malaria-COVID-19 co-infections, had been reported. Our previous study successfully revealed several compounds from Streptomyces hygroscopicus subsp. Hygroscopicus, including nigericin that has both antimalarial and antiviral effects. In malaria infection, Plasmodium falciparum Chloroquine Resistance Transporter (PfCRT) is the potential target for eliminating Plasmodium. Meanwhile, for SARS-CoV-2 infection, MPro is an essential protein for SARS-CoV-2 survival. This research aims to examine the potential effect of nigericin towards Plasmodium and SARS-CoV-2 by assessing its molecular interaction with PfCRT and MPro through molecular docking study. Methods: The protein target PfCRT and MPro were obtained from Protein Data Bank. Nigericin and the control ligand (chloroquine and N3) were obtained from PubChem. The pharmacokinetic analysis was done using SwissADME. Specific molecular docking was conducted using PyRx 0.9 and was visualized using LigPlot and PyMOL. Results: Nigericin has a large molecular weight, leading to the non-fulfillment of the Lipinski rule for oral administration. Through molecular docking study, the binding affinity of the Nigericin-PfCRT complex was -8.1 kcal/mol, and Nigericin-MPro was -8.6 kcal/mol. These binding affinities were stronger than the control ligand. The interaction between Nigericin-PfCRT and Nigericin-MPro share a similar pocket-site and amino acid residues as the control ligands. Conclusion: Nigericin has potential antimalarial and anti-coronavirus effects through molecular docking perspective by assessing the binding affinity and similarity of amino acid residues compared to control. Administration of systemic route can be an option in giving nigericin.

Background: The Chenopodium album L. commonly recognized as Bathua, is widely distributed globally and contains various phytoconstituents that help treat several diseases. However, until now, aerial parts{\textquoteright} antidiabetic potential and the plant{\textquoteright}s acute toxicity at fraction level have never been established. Objectives: To investigate the acute toxicity, the in-vitro, in-vivo antidiabetic potential of the plant at fraction level. Materials and Methods: The aerial parts of the plant were fractionated into different fractions, i.e., flavonoid fraction (CAFF), tannin fraction (CATF), alkaloid fraction (CAAF), saponin fraction (CASF), and were analyzed for in-vitro alpha-amylase inhibition assay. The CAFF, CATF, and CAAF were selected based on in-vitro alpha-amylase inhibition assay results and were further screened for its acute toxicity and in vivo antidiabetic activity using a high-fat diet and streptozotocin-induced diabetes model. The CAFF was characterized by LC-MS, and a molecular docking study was carried out. Results: The in-vitro alpha-amylase inhibition assay revealed that CAFF was found to be more potent than standard Acarbose having IC50 values 122.18 {\textpm} 1.15 and 812.83{\textpm} 1.07 μg/ml, respectively. The CAFF fraction was found to possess potent antidiabetic activity in a dose-dependent manner in both in vitro and in vivo diabetic models and did not produce any sign of severe toxicity. Furthermore, the bioactive CAFF fraction was characterized by LC-MS, showed the presence of quercetin 3-O-(2{\textquoteright}{\textquoteright},6{\textquoteright}{\textquoteright}-di-O-rhamnosyl) glucoside (QRG) or quercetin 3-O-(2{\textquoteright}{\textquoteright},6{\textquoteright}{\textquoteright}-di-Orhamnosyl) galactoside (QRGa) and quercetin 3-O-rutinoside (rutin) (QR). It is predicted from the molecular docking study that the CAFF fraction primarily acts as an alphaamylase inhibitor. Conclusion: The CAFF fraction was found to poses dose-dependent potent antidiabetic activity and did not produce any sign of severe toxicity and primarily act as an alpha-amylase inhibitor.

Background: ErbB4 is a member of ErbB family of receptor tyrosine kinases (RTKs) and plays an important role in resistance to ErbB2 inhibitors. Objective: This study aimed to design a pinostrobin derivative with activity as an ErbB4 inhibitor and to establish a quantitative structure-property relationship (QSPR) of pinostrobin and its derivatives to predict drug clearance. Materials and Methods: In this research, an in silico study was conducted on pinostrobin and its derivatives by predicting the prediction of activity spectra for substances (PASS) with PASS online, followed by molecular docking using the AutoDockTools 4.2.6 program on ErbB4 protein kinase and visualizing the docking results using the Discovery Studio Visualizer software. While the study of QSPR pinostrobin and its derivatives was determined using physicochemical parameters with clearance (CLtot) using SPSS. Results: From the data obtained, 5-O-2- phenylacetylpinostrobin has a high affinity for ErbB4 protein with a free energy of binding (ΔG) -10.37 kcal/mol and an inhibition constant (Ki) of 26.06 nM. Conclusion: Probability {\textquotedblleft}to be active{\textquotedblright} (Pa) 5-O-2- phenylacetylpinostrobin of 0.595 for kinase inhibitors and 0.666 for apoptosis agonists, thus becoming candidates for breast cancer drugs. The QSPR model can be used to predict the properties of molecules such as CLtot, this will be useful in the drug design process. The best QSPR regression equation for pinostrobin and its derivatives is Log (1/CLtot) = 0.705 Log S + 0.035 MR + 0.375. This equation can be used as a reference in predicting CLtot.

Background: Hypothyroidism is a common side effect found in patients with multidrug-resistant tuberculosis taking ethionamide. The mechanism of ethionamide-induced hypothyroidism is potentially caused by the structure of ethionamide compounds chemically similar to thioamide, such as propylthiouracil (C7H8N2S), which inhibits thyroid hormone synthesis. However, hypothyroidism is caused not only by a lack of production but also by signaling alteration. Thyroid hormone action is mediated by thyroid hormone receptors (TRs), members of the nuclear receptor superfamily that regulate their target genes. Unfortunately, there are limited studies on the potential interaction of ethionamide with TRs. Objective: In the present study, we want to elaborate on the potential interaction of ethionamide with TRs which might alter the thyroid hormone genomic regulation. Methods: Molecular docking studies were used to evaluate the potential interaction between ethionamide with TRα and TRβ. Results: The molecular docking results on TRα showed more than one hydrogen bond{\textendash}steric interaction formed from the ethionamide{\textendash}amino acid residue interaction. Ethionamide{\textendash}TRβ interaction showed more than one steric interaction, but the hydrogen bonds are not visualized. The docking score between ethionamide and TRα is -7.373 kcal/ mol and higher than its interaction with TRβ. Conclusion: These findings indicate that ethionamide can interact with TRα and TRβ. However, the ethionamide{\textendash}TRα interaction is stronger than ethionamide{\textendash}TRβ interaction. Our study reports a novel mechanism of action of ethionamide-induced hypothyroidism.

Indonesia, with its biodiversity, is overgrown by various kinds of plants that have medicinal potential, including Terap (Artocarpus odoratissimus Blanco). The leaves of A. odoratissimus are empirically used by local people of Borneo Island to treat gout. The purpose of this study was to determine the antigout activity of the active compound from A. odoratissimus leaves through xanthine oxidase inhibition using the molecular docking method and to determine the ADMET properties of these compounds. Phytochemical screening showed that A. odoratissimus leaf extract contained alkaloids, flavonoids, steroids/triterpenoids, and phenolics. The results of TLC showed that A. odoratissimus leaf extract contained steroid and flavonoid compounds in the form of stigmasterol and rutin. The results of molecular docking showed that flavan-3-ol provided the lowest bond-free energy against xanthine oxidase with a ΔG value of -8.3 kcal/mol, lower than allopurinol and hypoxanthine as reference ligands. Flavan-3-ol interacts with xanthine oxidase through hydrogen bonding with amino acid residues in the form of Arginine 912 and Lysine 1045. The prediction of ADMET properties from flavan-3-ol shows that the compound can be absorbed and has good permeability. Overall, the flavan-3-ol found in A. odoratissimus leaves shows the potential to be developed as a xanthine oxidase inhibitor for use in gout therapy.

Background: HIV continues to be a major global public health issue, having claimed more than 35 million lives so far. In 2016, 1 million people died from HIV-related causes globally. HIV-1 reverse transcriptase is one of HIV{\textquoteright}s vital enzymes for virus reproduction. If the enzyme is inhibited, the virus multiplication could be significantly decreased. There are currently many treatments for HIV, but more effective treatment is always needed because of the possibility of drug resistance and side effects for long-term use. Based on the previous study, there are some natural compounds with high affinity to the HIV-1 reverse transcriptase enzyme. Some of these compounds are flavonoid glycosides. Aims and Method: This study was aimed to learn more about in silico HIV-1 reverse transcriptase inhibitory activities of flavonoid glycosides using docking method. Results: The results showed that the most recommended flavonoid glycosides are those with the lowest binding energy, which were kaempferol-3-O-rhamnoside, myricetin-3-O-rhamnoside and quercetin-3-O-rhamnoside. This was due to the interactions of all three flavonoid rings and sugar moiety with key amino acid residues, which were Leu100, Lys101, Glu138, Tyr181, His235 and Tyr318. Conclusion: Flavonoid glycosides with rhamnose as glycone showed lower binding energy on HIV-1 reverse transcriptase.

Background: Allergens are foreign proteins that stimulate the production of immunoglobulin E (IgE), when they come in contact with human body. These allergens after binding with IgE through Fc\εRI receptor, triggers the signal transduction reaction in mast cell and basophil cells, leading to allergic reactions by releasing some mediators. Four correctly written as surface-exposed tryptpphans Trp 87, Trp 110, Trp 113 and Trp 156 of Fc\εRI receptor protein,play significant role in IgE and Fc\εRI receptor binding interaction. Polyphenols in apple are proven effective for allergic rhinitis treatment by preventing degranulation of granulocytes. Objective:To prevent release of mediators like histamine etc., a therapeutic strategy can be designed by inhibiting IgE and Fc\εRI receptor interactions.This strategy may provide a symptomatic treatment for allergic reactions due to exposure to pollen allergens. Materials and methods: Molecular docking studies are used to analyse the IgE with Fc\εRI receptor binding in presence and absence of procyanidin molecules, present in apple. Results: For procyanidin molecules, binding affinity of IgE molecule with its high affinity receptor (Fc\εRI receptor)decreases markedly. Thepositions of Trp 87, Trp 110, Trp 113 and Trp 156 are changed for the presence of procyanidin C1 molecule. Since IgE and Fc\εRI receptor binding is highly affected in presence of procyanidin C1, so this compound can inhibit mast cell degranulation by altering the binding affinity of IgE with its its high affinity receptor (Fc\εRI receptor). Conclusion: Procyanidin C1 can be used as natural anti-allergic drug by stabilizing mast cells during pollen allergic reaction after experimental verification.

Angiogenesis is considered as an essential pathological feature of cancer due to its interplay between cancer and other diseases. Natural products found to act as antiangiogenic agents that mediate the angiogenic switch between pro and anti angiogenic factors. Among the different targets, HIF is an important and critical factor that stands as a key mediator between angiogenesis, inflammation and cancer. In our study different phytochemicals of Brassicaceae were analysed for their drug like properties and mapped for pharmacophore development. The developed pharmacophore was virtually screened and further subjected to Lipinski and ADMET filters. The molecular interaction studies of the 10 retrieved compounds were studied by binding with HIF. Among the compounds 1stdrug like molecule HTS 0115 (C15H21BrN2O3) was found to have best docked score and its interaction was further validated using dynamics simulation. The compound found to share the pharmacophoric features with progoitrin a biochemical form of glucosinolate with reported anticancer and anti thyroid activities. Thus the drug like compound HTS 0115 can be further optimised as a putative HIF inhibitor in tumor angiogenesis.
