Coronavirus disease (COVID-19) is a disease of the respiratory tract caused by the coronavirus (SARS-CoV-2). Jubanine A, jubanine B, jubanine C, jubanine G, and jubanine H compounds in the arabian bidara plant (Ziziphus spina-christi L.) are known to treat viral and bacterial infections. The purpose of this study was to test the affinity of the compounds jubanine A, jubanine B, jubanine C, jubanine G, and jubanine H in the arabian bidara plant to the non-structural protein 15 (Nsp15) receptor. This research was carried out by identifying the physicochemical properties of the test compounds using the swissADME server. After that, geometry optimization was performed using the Quantum ESPRESSO 6.6 software, then macromolecule preparation was accomplished using the BIOVIA Discovery Studio 2020 software. Furthermore, method validation and molecular docking simulations were demonstrated using MGLTools 1.5.6 software with AutoDock Tools 4.2. Then the analysis of the molecular docking results was carried out using the BIOVIA Discovery Studio 2020 software. Finally, the toxicity of the test compound was predicted using the Toxtree 3.1.0 software. Based on the results of free binding energy (âˆ†G), jubanine H has the best affinity among the other five compounds with the lowest binding energy value of âˆ’6.51 kcal/mol.

The COVID-19 has spread worldwide and become an international pandemic. The promising target for drug discovery of COVID-19 was SARS-CoV-2 Main Protease (Mpro), that has been successfully crystallized along with its inhibitor. The discovery of peptide-based inhibitors may present better options than small molecules for inhibitor SARS-CoV-2 Mpro. Natural compounds have such a wide potential and still few explored, Zizyphus spina-christi is one of the medicinal plants that have many pharmacological activities and contains a peptide compound from alkaloids class, i.e. cyclopeptide alkaloids, that is interesting to explore as SARS-CoV-2 Mpro inhibitor. The compound structure was drawn and optimized using density functional theory 3-21G method. The protein chosen was the high resolution of SARS-CoV-2 MPro receptor (1.45 Å) with PDB ID: 6WNP, in complex with boceprevir. Molecular docking simulation was performed using Autodock4 with 100 numbers of GA run, the validation methods assessed by RMSD calculation. Furthermore, the prediction of pharmacological activity spectra was carried out using the PASS Prediction server. The results showed RMSD value was 1.98 Å, this docking method was valid. The binding energy of all compounds showed better results than the native ligand (Boceprevir). The in silico PASS prediction results indicated that all compounds showed antiviral activity. Some compounds showed protease inhibitory activity, i.e Ambiphibine-H, Franganine, and Mauritine-A, and the highest Pa (Predicted activity) value showed by Mauritine-A compounds. It can be concluded that the cyclopeptide compounds of Zizyphus spina-christi were indicated to have a potential as COVID-19 therapy targeting SARS-CoV-2 Mpro.

Infectious diseases have lately become pandemic, posing a threat to global public health with the introduction of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), previously provisionally named 2019 novel coronavirus or 2019-nCoV). Technological advancements have increased the possibility of discovering natural inhibitor candidates capable of preventing and controlling COVID-19 infections. The SARS-CoV-2 3C-like protease (3CLpro) is critical for SARS-CoV-2 replication and is a prospective therapeutic target. This study aims to identify, evaluate, and explore the 3CLpro macromolecular structures from SARS-CoV and SARS-CoV-2, as well as their impact on angiotensin-converting enzyme 2 (ACE-2). The discovery of the two 3CLpro macromolecules revealed structural similarities in several regions. These findings were subsequently confirmed by performing protein-protein docking simulations to observe the interaction of 3CLpro with the active site ACE-2. With an ACE score of 701.41 kJ/mol, SARS-COV-2 3CLpro forms the strongest binding with ACE-2. As a result, the findings of this research can be used to guide the development of potential SARS-CoV-2 3CLpro inhibitors for the treatment of COVID-19 infectious diseases.

Enzim tirosinase merupakan enzim utama pada proses pembentukan pigmen melanin. Penghambatan aktivitas enzim tirosinase secara kompetitif maupun non-kompetitif menjadi kunci utama pengembangan agen pencerah kulit. Asam ferulat merupakan salah satu senyawa antioksidan yang kuat dan mampu melindungi kulit dari dampak buruk sinar UV yang menginduksi stress oksidatif. Penelitian ini bertujuan untuk mengidentifikasi interaksi molekuler antara senyawa asam ferulat dari kulit buah nanas (Ananas comosus) dan turunannya dengan enzim tirosinase menggunakan motode dinamika molekuler. Molekul senyawa uji dimodelkan menggunakan perangkat lunak Quantum ESPRESSO v.6.6. Model terbaik dipilih untuk dilakukan studi interaksi menggunakan perangkat lunak MGLTools 1.5.6 yang dilengkapi dengan AutoDock 4.2. Konformasi terbaik hasil penambatan molekuler kemudian dikonfirmasi stabilitasnya dengan simulasi dinamika molekuler menggunakan perangkat lunak Gromacs 2016.3. Berdasarkan hasil dari penambatan molekuler, senyawa asam iso-ferulat memiliki afinitas yang paling baik, yaitu dengan nilai energi bebas ikatan −25,06 kJ/mol dan memilki ikatan dengan logam seng (Zn) pada sisi aktif enzim tirosinase. Kemudian senyawa tersebut memiki stabilitas interaksi yang baik berdasarkan grafik RMSD, RMSF, Rg, SASA, RDF, dan H-Bond.

Warisan budaya bangsa Indonesia yang masih digunakan hingga saat ini khususnya dalam pemeliharaan dan peningkatan kesehatan serta pencegahan dan pengobatan penyakit adalah penggunaan obat tradisional. Salah satu tanaman yang dapat dimanfaatkan adalah temulawak (Curcuma Xanthorrhiza) yang dapat diolah sebagai minuman instan dalam bentukserbuk yang mudah dan praktis dalam penyajiannya serta dapat memperpanjang umur simpan. Namun sebagian besar masyarakat belum pernah memperoleh pelatihan tentang pemanfaatan produk herbal untuk peningkatan pola hidup sehat. Untuk mengatasi masalah tersebut maka perlu dilakukan suatu kegiatan dengan tujuan untuk meningkatkan keterampilan masyarakat dalam memanfaatkan tanaman obat secara praktis dan mudah sebagai bagian dalam peningkatan hidup sehat. Kegiatan ini dilaksanakan di Desa Boro-Boro Lameuru Kecamatan Ranomeeto Barat Kabupaten Konawe Selatan, Sulawesi Tenggara dengan melibatkan masyarakat dengan menggunakan metode pelatihan dengan cara mendemonstrasikan pembuatan minuman instan. Hasil kegiatan pelatihan diperoleh produk herbal berbentuk serbuk temulawak berwarna kuning, aroma khas temulawak dan tekstur yang sedikit kasar dengan ukuran yang homogen serta masyarakat suka terhadap produk yang dihasilkan. Temulawak juga diketahui memiliki khasiat meningkatkan sistem imun, menyegarkan tubuh, memperlancar metabolisme, menyehatkan fungsi hati, menambah nafsu makan, sebagai imunomodulator, hepatoprotektor, dan dapat meningkatkan daya tahan dan stamina tubuh. Kegiatan ini dapat meningkatkan keterampilan masyakat dalam memanfaatkan bahan alam yang tersedia untuk meningkatkan kesehatan atau mencegah paparan dari penyakit terutama dimasa pandemi seperti saat ini.

EGFR receptors play an important role in the growth of cancer cells, and these receptors have undergone various types of mutations. At this time, the effect of the L718Q / T790M point mutation on the EGFR receptor is not known, therefore the aim of this study is to predict the EGFR structure with the L718Q / T790M point mutation using in silico homology modeling. The mutant protein was successfully modeled using SWISS-Model expasy webserver and showed good evaluation results after the protein was minimized as indicated by the results of the Ramachandran outlier score of 0%, clashscore 0.98, and MolProbity 1.15. Identification of the active site of the mutant protein shows a conformational change of the active site that causes a steric collision between the inhibitor group and the amino acid side chain of the mutant protein. Keywords: EGFR, mutation, homology modeling, in silico.
