Abstract

Malaria is a serious caused by protozoan parasites such as Plasmodium groups and has fatal consequences for human health. The increase in the resistance of the Plasmodium parasites toward existing antimalarial drugs prompts the exploration of novel compounds. In this study, quantitative structure-activity relationship (QSAR) analysis using the semi-empirical AM1 method was conducted to identify the optimal model that relates physicochemical properties and biological activity of chalcone derivatives.  In addition, ADMET prediction and molecular docking were also carried out. Multilinear regression calculations for statistical parameters of QSAR models revealed that Model 4, with 11 independent variables, provided the best predictions and exhibited a robust correlation with antimalarial activity represented by inhibitory concentration (IC50). ADMET predictions indicated favorable absorption, distribution, metabolism, excretion, and toxicity properties, particularly for B2D, showing promising antimalarial attributes. Molecular docking studies targeting 5 mutated PfDHODH proteins revealed B2D's potential to reach therapeutic targets efficiently. It has low docking scores for mutations I (-10.5 kcal/mol), II (-8.6 kcal/mol), and V (-10.5 kcal/mol) with RMSD < 2í…, in carrying out its role for antimalarial activity. This research successfully identifies B2D as an efficient inhibitor of PfDHODH receptors. Thus, it is a highly promising novel antimalarial drug.

Abstract

Chemistry is not merely a science that only studies theory in class. Chemistry learning requires practical or experimental activities to observe and directly apply chemical concepts during face-to-face meetings in class. Meanwhile, the unavailability of laboratory facilities is one of the factors in not carrying out chemistry practice. This causes students difficulties in understanding the concept of chemistry as a whole and can potentially reduce learning motivation. This public service activity aims to implement the Hyperchem software for teachers and students of SMA Negeri 1 Mawasangka Timur as an alternative solution for chemistry labs in the form of electronic labs. The chemical topics selected and considered suitable for this type of practice were the structure and properties of chemical compounds. This activity is carried out in the form of a workshop. Workshop materials use lectures, simulations, discussions, and question-and-answer models. The activity's results showed the workshop participants' enthusiasm to use the Hyperchem software as a chemistry lab media. This is reflected in the evaluation of the workshop implementation, which is carried out by assessing the response of the workshop participants based on indicators of relevance, the ability of the presenters, ease of use, availability, and usefulness of the Hyperchem software. The evaluation results show that the workshop and the implementation of the Hyperchem software as an electronic practice media for visualizing the structure and properties of chemical compounds received a positive response from the workshop participants.

Abstract

Corrosion is a severe problem in the petroleum industry. The use of corrosion inhibitors is an effort to reduce the corrosion rate on metal materials. This study used the computational chemistry approach to investigate the corrosion inhibition performances of 4,5-diphenyl imidazole and its derivatives with additional substituents, for instance, electron acceptors and electron donors. Geometry optimizations and calculations of molecular frontier orbital energies were conducted using density functional theory (DFT) in the aqueous phase. These frontier orbital energy values were used to determine other reactivity and stability parameters, such as band gap energy, electron affinity, ionization potential, chemical hardness, chemical softness, number of electron transfers, chemical potential, nucleophilicity, electrophilicity, electronegativity, back donation energy, and interaction energy. Electrostatic potential, Mulliken atomic charge, and theoretical inhibition efficiency of 4,5-diphenyl imidazole derivatives were also determined. Generally, the presence of electron donor substituents theoretically increases corrosion inhibitors. The 4,5-diphenyl imidazole with –NH2 substituent is a better derivative than others based on several reactivity and stability parameters due to adding adsorption centers. Therefore, it can increase the performance of 4,5-diphenyl imidazole as a corrosion inhibitor. The adsorption behaviors of 4,5-diphenyl imidazole and its derivatives on Fe(100) surfaces were investigated using molecular dynamics simulation. The binding energies of three types of inhibitors on the Fe surface of studied inhibitors followed the order: D–NH2 > 4,5-diphenyl imidazole (D) > D–NO2. This ranking obtained is consistent with the theoretical inhibition efficiency.

Abstract

Lung cancer remains one of the leading causes of global mortality, primarily due to drug resistance and the adverse effects of conventional therapies. Therefore, the discovery of novel compounds that are both effective and safe is crucial for the development of alternative treatments. This study employed a computational approach to evaluate the therapeutic potential of Xanthomicrol-derived compounds targeting mutated proteins commonly associated with lung cancer. Four derivatives (u1a, u2a, u3a, and u4a) were assessed using pharmacokinetic (ADMET) predictions, molecular docking, and molecular dynamics simulations against ten mutated lung cancer-related proteins (1nq1, 1x2j, 4b3z, 4j97, 5l2q, 6pwa, 6usx, 7pgk, 7pgl, and 7r7k). ADMET predictions revealed that all compounds had good gastrointestinal absorption, did not cross the blood–brain barrier, and exhibited favourable safety profiles. Among them, compound u3a showed the highest binding affinity toward seven mutated proteins, with docking scores ranging from -5.9 to -9.4 kcal/mol. Molecular dynamics simulations further supported the stability of u3a protein interactions, indicated by low RMSF values and an optimal radius of gyration. These results suggest that u3a is a promising candidate for targeted lung cancer therapy and warrants further experimental validation.

Abstract

Eucheuma cottonii is one type of seaweed that has the potential to be an antioxidant. This seaweed grows and is distributed in various waters of Indonesia, especially in Southeast Sulawesi. However, information regarding the antioxidant activity and the compound content of E. cottonii in this area is still limited. Therefore, this research aims to determine the compound and antioxidant activity profile in E. cottonii. The study used laboratory experimental methods. The research stages were preparation (seaweed sampling), extraction, qualitative phytochemical screening, and antioxidant assay. The initial identification of compounds using qualitative phytochemical screening methods with three extraction solvents: ethanol, ethyl acetate, and n-hexane. Meanwhile, the antioxidant test employed the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. The results of qualitative phytochemical screening revealed that the seaweed extract of E. cottonii contains saponins, tannins, and terpenoids. The antioxidant assay using the DPPH method indicated that among the three extraction solvents used, ethanol extract exhibited a very strong antioxidant activity (with an IC50 of 30,036 ppm), compared to ethyl acetate extract (IC50 of 182,179 ppm) and n-hexane extract (IC50 of 641,454 ppm). This study concluded that E. cottonii seaweed has the potential to be developed as a source of natural antioxidants or raw material for the discovery of antioxidant medicines in the future.
