Exploration of natural compounds is one of the projects in the context of curving disease, one of which is inflammatory therapy in the body, one of the natural ingredients used is Phloroglucinol which has anti-inflammatory properties but there is no information on molecular studies related to its activity. The purpose of this study was to explore the potential of Phloroglucinol as an anti-inflammatory mechanism. Phloroglucinol compound (CID 359) was downloaded from the PubChem Protein COX-2 database (PDB ID 6cox) downloaded from the Protein Data Bank database. The compound Phloroglucinol interacted with the Molegro virtual Docker 5 program with Grid docking X 66,44; Y 27.44; Z 107.23. The docking results were analyzed using Discovery Studio software ver 21.1.1. The results showed that Phloroglucinol binds to five COX-2 amino acid residues and may inhibit COX-2 performance and can be a strong candidate for inflammatory therapy when inflammation occurs. in the human body. The conclusion of this study is that Phloroglucinol compounds have the potential in inhibiting COX-2 (inflammatory mediators).

Background: Hypertension is a disease with increasing characteristics of blood pressure. The ACE gene has a role in the conversion of ATI to ATII in hypertensive conditions. Healing is done by using the 8-gingerol content contained in ginger. The purpose of this study is to analyze the molecular interaction that occurs between 8-gingerol and ACE. Method: ACE model proteins (ID: 3bkk) were obtained from the Bank Data Protein database (PDB) through 8-gingerol ligands (CID: 168114) obtained from the PubChem database. ACE and 8-gingerol were docked by Discovery Study Client 4.1 software. Analysis of amino acid residues, binding energy, Van der Waals forces, and hydrogen bonds formed using Discovery Studio Client 4.1. Results: The interaction between 8-gingerol and ACE showed that there were seven amino acid residues that interacted with 8-gingerol, also found hydrogen bonds, hydrophobic and Van der Waals forces that strengthen and stabilize these bonds. Conclusion: the interaction of 8-ginger with the active side of ACE is determined as an ACE inhibitor, the inhibition is a significant effect on the obstruction of ACE conversion.

Corona virus 19 menjadi pandemic di dunia saat ini, oleh karena itu perlu dilakukan terapi sehingga menurunkan prevalensi di Indonesia dengan menghambat protein yang terlibat dalam virus corona (3CL Protease). Salah satunya pemanfaatan bahan alam yang tidak terpakai. Kulit kopi merupakan material sisa dari pengolahan biji kopi. Satu ton ampas kopi akan terbentuk dari 2 ton kopi yang diproduksi dan berdampak terhadap masalah lingkungan. Kulit kopi memiliki berbagai macam senyawa yang masih dibutuhkan. Produksi kopi Tujuan penelitian ini adalah pemanfaatan bahan aktif kulit kopi sebagai nutrisi tingkat gen dengan menghambat kinerja 3C-like protease (3CLPro). Metode penelitian in silico, senyawa kulit kopi Hexosa (ID. 206), Malic acid (ID. 525), D-manitol (ID. 88038555) diunduh dari PubChem, protein 3CL Protease diunduh dari database protein data bank (PDB) dengan ID 2zu2 diimport ke software Molegro virtual docker 5 dan dilakukan preparasi. Selanjutnya protein target diprediksi cavity (sisi aktif protein) dengan parameter expand van der Waals maximum 10. Hasil docking dilakukan superimposed dengan protein yang telah dipreparasi menggunakan software PyMol. Visualisasi hasil docking dilakukan menggunakan perangkat lunak HEX 8.0.0.0. Hasil penelitian senyawa yang terkandung dalam kulit kopi memiliki potensi sebagai anti covid-19, hal ini dibuktikan dengan aktivitas senyawa Hexosa, Malic acid, D-manitol yang mengikat masing-masing enam residu asam amino. Pengikatan terhadap delapan belas residu asam amino yang berbeda diprediksi menjadi alternatif nutrisi dengan menghambat 3CL Protease.

Papain-like protease is a SARSCOV-2 protease that functions for ubiquitination in host cells. Caffeine compounds have been widely reported to have antioxidant, anti-inflammatory, antidiabetic, and antiobesity activities. However, hexose and malic acid compounds in coffee rind as potential inhibitors of the papain-like protease SARSCOV2 have not been reported. This study investigated the potential of malic acid and hexose compounds as PLPro inhibitor agents in inhibiting SARSCOV2 ubiquitination. In silico studies were used to identify the potential of the two compounds by interacting hexose and malic acid compounds with papain-like protease (PLPro) proteins with the Molegro virtual Docker 5 program. Next, the ligand-protein complex visualization was done with discovery studio version 5.0. hexose and malic acid compounds showed interactions with papain-like protease proteins on several active site residues. The interactions showed inhibition of ubiquitination and stimulation of interferon in host cells. The two compound complexes – PLPro protein showed hydrophobic interactions, hydrogen bonds, and van der Waals forces, which contributed to the formation of bond energy and strong bonds between compounds and proteins. In this study, it was concluded that hexose and malic acid compounds have the potential to act as inhibitors of papain-like protease (PLPro) protein.

The number of tuberculosis (TB) cases worldwide reached 1.5 million in 2018; thus, TB is considered a deadly disease. TB is caused by Mycobacterium tuberculosis and involves lipid synthesis. Considering the importance of lipid metabolism in bacteria, FabH may be an essential protein target for repressing lipid synthesis. Capsaicinoids from Capsicum annuum demonstrate potent antibacterial activity. This study predicted the ability of capsaicinoid compounds to inhibit FabH. In silico analysis was performed by retrieving the structure of FabH from PDB and those of selected capsaicinoid derivatives from PubChem. The compounds were docked using AutoDock Vina in PyRx 0.8 software. The interactions of FabH and different capsaicinoid derivatives showed identical binding characteristics. The bonding type most frequently observed was hydrogen bonds. In conclusion, capsaicinoid derivatives could block lipid synthesis through FabH. The relevant mechanism and biological processes should be studied further.

This study aims to explore the chemical compounds of the coffee pulp as an anti-covid-19 (anti-3C-like protease). In silico modeling was carried out by structure retrieval, protein preparation, and docking simulation. Specific Grid docking was used for ligands – protein interacting by using Molegro Virtual Docker 5, followed by visualizing Discovery studio version 21.1.1. Compounds contained in coffee pulp, quinic acid, gluconic acid, and ferulic acid separately bind to the same amino acid residues of 3CL Protease or each other. Furthermore, three compounds inhibited 3CLPro activity by catalytic site blocking of 3CLPro, indicating that coffee compounds have potential as molecular therapeutic materials for the coronavirus by inhibiting SARS-CoV-2 genome replication.
