Abstract

The sap of kemenyan toba (Styrax sumatrana) is often used as a binder for perfumes, raw materials for cosmetics and medicines, so it is widely traded. However, not many studies have reported about its chemical composition. The process of extracting chemical compounds from kemenyan toba (S. sumatrana) sap quality one was carried out by maceration method using n-hexane and water distillation. The result of maceration was 25.3% of the n-Hexane extract, while the distillation yielded 0.13% (w/w) of a pale-yellow oil. The results of the GC-MS analysis showed that only benzoic acid was present in the extracts and essential oils. n-Hexane extract consists of styrene compounds, cinnamic acid, benzyl benzoate, 1,4-diphenyl-1.4-butanedione, benzyl cinnamates, methyl styrene, and cinnamyl cinnamate. In comparison, essential oil consists of 3-methylpentan-2-one, methyl palmitate, methyl stearate, methyl trans-9.10-epoxystearate, dioctyl hexanedioic, methyl oleic, and methyl-13.16-Octadecanoic. The in-silico test results of several compounds as antiinflammatory showed that the compounds cinnamyl cinnamate had potential as an anti-inflammatory.

Abstract

Glikolisis merupakan proses oksidasi glukosa yang melibatkan enzim hingga menghasilkan asam piruvat dalam kondisi aerob serta asam laktat dalam keadaan anaerob. Enzim-enzim yang terlibat di dalam glikolisis dapat berinteraksi dengan logam berat, melalui pengikatan secara kovalen terhadap residu asam amino dari enzim. Untuk membuktikan hal tersebut, digunakan metode in silico dengan menggunakan MIB: Metal Ion-Binding site prediction dan server docking dari Lu Lab@StructuralBioinformatics, China Medical University (http://bioinfo.cmu.edu.tw/MIB/). Enzim-enzim kunci pada glikolisis diperoleh dari RCSB Protein Data Bank (https://www.rcsb.org/search), yakni enzim glukokinase dengan kode PDB: 3FGU, enzim heksokinase dengan kode PDB: 4IXC, dan enzim piruvat kinase dengan kode PDB: 1ZJH. Protein disiapkan dengan menghilangkan residu ligan alami yang ada dalam protein. Persiapan ligan dan protein digunakan oleh program Chimera 1.15. Hasil penelitian mengungkapkan bahwa interaksi Hg terhadap enzim glukokinase, heksokinase, dan enzim piruvat kinase lebih reaktif dibanding Cd. Pada glikolisis, Cd banyak berinteraksi dengan residu asam glutamate dan residu histidine sedangkan Hg banyak berinteraksi dengan sistein pada enzim-enzim glikolisis. Pembentukkan kompleks Hg dengan resisdu sistein, menyebabkan Hg akan berikatan dengan gugus thiol bebas yang tersedia. Merkuri yang terikat pada gugus thiol pada residu sistein mengakibatkan fungsi residu sistein pada protein tidak berjalan dengan semestinya sehingga enzim tidak aktif dan glikolisis terganggu.

Abstract

Determining the 3D structure of proteins using laboratory instrumentation is time-consuming and expensive. The in silico method can be used as an alternative to predict the 3D structure of proteins, such as the fold recognition method. This study aims to create a 3D structural model of rice's (Oryza sativa) protein superoxide dismutase (SOD). The 3D structure modeling of the protein was carried out with the Phyre2 web server. The protein sequence was obtained from the UniProt KB database with the code A0A6F8FUX1. The results showed that the suitable template used to build the model was the template with the code c1unfX. The c1unfX template has a coverage value of 80%, 100% confidence, and i.d. of 51%. Validation of the model with the PROCHECK program showed that the most favored area on the Ramachandran Plot was 87.8%, and the disallowed area was 1.1%. The disallowed area, which is still below 15%, indicates that the three-dimensional structure model of the SOD protein built from the c1unfX template has good a value.

Abstract

Vegetable farmers in South Kalimantan use pesticides to protect crops from pests. The active ingredient of the pesticide has a broad toxic effect on target and non-target organisms. Continuous exposure to pesticides causes cancer. The plant of mantle (Stenochlaena palustris) is thought to have potential cytotoxic activity against cancer cell growth. The aim of this study was to examine the potential activity of chemical compounds in anaplastic lymphoma kinase (ALK) exposed to organophosphate pesticides in silico and in ovo. The in silico study used molecular docking and virtual screening methods. The methanol extract of malachite was obtained by maceration method. The in ovo study was carried out by injecting pesticide compounds and methanol extracts of methanol at doses of 0.5 and 1 ppm to free-range chicken eggs. The results of the in silico analysis showed that ethion and neophytadiene had the most negative G values, namely -8.62 kcal/mol and -8.39 kcal/mol, while the natural ligand 8 LY A 500 was -9.19 kcal/mol. The similarity of the type and number of residues in the binding complex between ethion and neophyadiene ligands with ALK protein indicates the potential for competition between ethion and neophyadiene when bound to ALK protein. Neofitadiene is suspected as a compound that has potential as anti-cancer by inhibiting the growth of ALK. Anchovy extract is considered to be able to slow down the rate of cell damage in chicken embryos caused by ethion with its inhibitory ability so that the cell surface is not damaged quickly.

Abstract

Knowledge of the three-dimensional structure of proteins is very important to understand their character and function at the molecular level. Determination of protein structure in the laboratory is expensive and relatively difficult because it requires sophisticated instruments and takes a long time. As an alternative, an in silico approach can be used to predict the three-dimensional structure of proteins, namely the fold recognition method. The purpose of this study was to create a three-dimensional structure model of snakehead fish (Channa striata) calponin protein using the Phyre2 web server. The target protein sequence was obtained from UniProt KB with code K9LH64. The results of the study showed that the template for building the model was the c1wynA code. The results of the model (MP) evaluation obtained a coverage value was 45%, a confidence value was 100%, and an identity value was 69%. Validation of the model (MP) using the PROCHECK program showed the model was in the most favoured residue plot of 82.4%. This model deserves to be used as a model for calponin protein of snakehead fish, because the disallowed area was below 15%. The results of the analysis of interactions with other proteins using STRING-DB obtained the interaction model (MP) with Actin assembly-inducing protein (ACTA2) was 0.791; and Tropomyosin (TPM1) was 0.786. The results of molecular docking using PatchDock obtained the value of Atomic Contact Energy (ACE) for the calponin protein model (MP)-ACTA2 was 372.76 kJ/mol; Calponin model protein (MP)-TPM1 was 406.93 kJ/mol.
