It is presumed that antiproliferative activity of anthocyanidin has interaction with Epidermal Growth Factor Receptor (EGFR) which has effect on lung cancer cell growth. This study aimed to observe the interaction between anthocyanidin and EGFR and to find out prediction, absorption, distribution activities as well as anthocyanidin toxicity compared to Gefitinib, an EGFR inhibitor. All test compounds were optimized with Autodock Tools®, then molecular docking simulations and predictions of absorption, distribution and toxicity were carried out. Malvidin was stated to meet the Lipinski's Rule of Five, indicating good bioavailability. Result of molecular docking simulation showed that malvidin had better affinity against EGFR than Gefitinib. Molecular docking visualization result showed that malvidin had interaction with amino acid residue such as Met793, Gln791, Leu718, Thr854, Asp855 and Lys745. Absorption and distribution predictions included percentage scores of Human Intestinal Absorption (HIA), human colon adenocarcinoma (Caco-2), and Plasma Protein Binding. Toxicity test revealed that malvidin was mutagenic compound but not carcinogenic one. The findings indicated that malvidin was potential to be an anti lung cancer candidate through EGFR inhibition.Keywords: Antiproliferative, Anthocyanidin, Epidermal Growth Factor Receptor, Molecular Docking

In vitro testing showed that awar awar (Ficus septica Burm. L ) leaf had an anticancer activity. Ethanol extract from awar-awar leaves could selectively inhibit cancer cell growth with IC50 values, there were MCF7 breast cancer cells (48 µg/ml), HeLa cervical cancer cells (122.4 µg/mL), and WiDR cancer cells (75.9 µg/mL). However, the active compounds that play a role in inhibiting the three cancer cells are not yet found. Therefore, this research carried out to find out the active compound using in silico. 3D-pharmacophore modeling and Molecular docking were developed for finding out the potential compound that could be acted as an anti-cancer agent. Screening pharmacophore was performed using LigandScout® 4.4 software for searching the matching pharmacophore features against chemical structure databases. Docking was performed using Autodock Tools® and visualized using Discovery Studio Visualizer® software to see the ligand interaction with the active binding site at the receptor and continue with ADMET properties to evaluating the Pharmacodynamic activities of the Hit compounds. Among 17 types of compounds tested, 11 compounds showed anticancer activity and genistin was found promising and showed potential inhibitory characteristics as an anticancer compared to other active compounds of awar-awar leaves. This study suggests that these compound could be used as a lead compound for anticancer agents.

The COVID-19 outbreak prompted the development of novel drugs to treat the disease. Targeting of virus proteins has attracted great interest in the discovery of COVID-19 drugs. 3CLpro and PLpro are promising targets because of their important role in viral replication. Hence, various efforts have been made to find specific therapeutics for COVID-19, including those derived from plants as anti-Covid-19. Red ginger rhizome (Zingiber officinale var. rubrum) contains secondary metabolites that are known for their health benefits. This in silico study aimed to determine the potency of red ginger rhizome as PLpro and 3CLpro of SARS-CoV-2 inhibitor which may be applied to treat COVID-19. This research was conducted using molecular docking and molecular dynamics simulations. The molecular docking simulation of red ginger compounds in complex with SARS-CoV-2 PLpro showed that 27 compounds have a binding free energy (?G) lower than that of the reference ligand. On the other hand, none of the complexes between red ginger compounds and 3CLpro had a lower binding free energy than the reference ligand. Visualization of interaction features at the PLpro of SARS-CoV-2â€™s active site shows that secondary metabolites dominantly interact with hydrogen bonds. The ar-curcumene and PLpro complex of SARS-CoV-2 appears very stable and has the lowest flexibility compared to HBA as a native ligand and molnupiravir as a reference ligand based on RMSD and RMSF plot analysis using molecular dynamic simulation...

Breast cancer has the highest prevalence of all cancers. Breast cancer has overtaken lung cancer as the leading cause of global cancer incidence in 2020, accounting for 2,261,419 new cases, or 11.7% of all new cancer cases worldwide. Among the efforts that can be done are efforts to find breast cancer medications that are safe and selective for the treatment and prevention of cancer, particularly those derived from medicinal plants. The Malay apple (Syzygium malaccense (L.) Merr. and L.M. Perry) is one plant that has been extensively examined and proved to have an antiproliferative effect. The pharmacophore modelling, molecular docking, and molecular dynamic approach was conducted on 155 active compounds of Malay apple to alpha and beta estrogen receptors. According on the results of ER-lamda docking, numerous substances have binding free energy values less than 4-OHT yet are not bound to important amino acids, as the result, it is not continued to the next test. On other side, with a fit score of 45.81, rutin was potentially selective for ER-beta receptors, molecular docking to ER-beta obtained that rutin was predicted to have breast cancer activity with a free binding energy value of -10.6 kcal /mol with better conformation and affinity compared to native ligand (genistein), and bound to essential amino acids as anticancer breast at ARG 346, GLU 305, and molecular dynamics simulations show that the compound has good stability when binding to the receptor. In silico toxicity prediction from rutin showed outcomes that match the requirements for the candidate drug. However, because it does not match the ADME prediction and Lipinsky's rule of five, rutin must be optimalization to improve its pharmacokinetic and pharmacological profile before it can be further explored as a therapeutic option for the treatment of breast cancer that targets the ER- receptor.

Phenylbutazone is a pharmaceutical substance often added to rheumatic herbs. However, because of the complexity of the matrix caused by the presence of compounds in herbal medicines, the determination of phenylbutazone requires a time-consuming sample preparation process prior to analysis. This study was conducted to develop a specific sorbent that can be used to prepare phenylbutazone in herbal medicine. The performance of phenylbutazone Molecularly Imprinted Polymer (MIP) was evaluated using three distinct porogens (ethanol, methanol, and methanol-chloroform (1:1)) and two polymerization procedures (bulk and precipitation). According to the results of the polymer optimization, the polymer generated by precipitation in methanol-chloroform (1:1) has good sorbent characteristics. FTIR physical characterization revealed complete polymerization. The bulk procedure produces a more physically stable sorbent than the precipitation method does. Keywords: MIP Performance Evaluation, Phenylbutazone Molecular Imprinted Polymer, Polymer Imprinting Factor
