Abstract

A comprehensive QSAR analysis, in conjunction with molecular docking, molecular dynamics simulations, MM-PBSA binding energy estimations, and ADMET profiling, was conducted to facilitate the development of novel anticancer agents based on hydroxyxanthone derivatives. Molecular and electronic descriptors were calculated using the DFT method with the 3-21G basis set. The best QSAR model identified several descriptors that significantly influence anticancer activity, including the atomic charges at positions C1, C3, C4a, and C7, as well as the highest occupied molecular orbital (HOMO), surface area (SA), molecular volume (VOL), and molecular weight (MW). This model was used to design novel hydroxyxanthone derivatives (X27 to X47). The docking result showed that compounds 7-bromo-3-hydroxy-1-(methylamino)-9H-xanthen-9-one (X43), 6-hydroxy-8-(methylamino)-9-oxo-9H-xanthene-2-carbonitrile (X44), and 3-hydroxy-7-mercapto-1-(methylamino)-9H-xanthen-9-one (X45) had stronger binding energy values than gefitinib as a native ligand. Gefitinib had a binding energy of -6.84 kcal/mol, while those compounds had values of -6.92, -7.12, and -6.92 kcal/mol, respectively. In a molecular dynamics simulation of 100 ns, compounds X43, X44, and X45 exhibited stability comparable to that of gefitinib against the EGFR protein. Additionally, the binding energy MM-PBSA of compound X43 was the lowest (-29.18 kcal/mol), followed by X44 (-27.11 kcal/mol), gefitinib (-26.06 kcal/mol), and X45 (-25.21 kcal/mol). Furthermore, these compounds met Lipinski's rule parameters and the minimal standard parameters in terms of ADMET characteristics, as predicted by physicochemical properties. In conclusion, compounds X43, X44, and X45 are potential anticancer agents for MDA-MB-231 breast cancer cells.

Abstract

This research employs an artificial intelligence (AI)-driven molecular docking approach to identify potential antidiabetic compounds from Syzygium polyanthum phytochemicals targeting the α-glucosidase enzyme. The docking simulations were conducted using the PLANTS software, which utilizes an ant colony optimization (ACO) algorithm, a nature-inspired AI technique that mimics the foraging behavior of ants to explore ligand binding conformations efficiently. PLANTS integrates multiple empirical scoring functions, including ChemPLP, to evaluate protein-ligand interactions by modeling steric complementarity, hydrogen bonding, and torsional potentials, enabling accurate prediction of binding affinities. The protein structure with PDB code 2JKE was validated with a root-mean-square deviation (RMSD) of 0.2912 Å, confirming the reliability of the docking protocol. Screening results revealed seven phytochemical compounds Hexadecanoic acid 2-hydroxy-1-(hydroxymethyl), Methyl oleate, Methyl palmitate, Phytol, 9,12,15-Octadecatrien-1-ol, Nerolidol, and Eicosane exhibited lower docking scores (-96.2919 to -80.5188) than both the reference drug miglitol (-80.2642) and the native ligand (-77.2910), indicating stronger and more stable binding to the α-glucosidase active site. These findings suggest that the identified compounds have superior theoretical inhibitory potential compared to miglitol, a clinically used α-glucosidase inhibitor. The AI-based in silico screening using PLANTS thus provides a powerful, cost-effective strategy for accelerating antidiabetic drug discovery by prioritizing promising natural compounds for further experimental validation.

Abstract

Chlorochalcone derivatives (chalcones 1–3) were synthesized using ultrasound-assisted Claisen-Schmidt condensation, yielding > 80%. Antioxidant activity was evaluated through DPPH and ABTS assays, demonstrating strong activity with IC50 values ranging from 61.52 ± 0.97 to 98.27 ± 1.42 ppm. Chalcones 1 and 2 show SPF potential at 40 ppm and chalcone 3 at 20 ppm (SPF 19.47 ± 0.46). ADMET analysis using the pkCSM tool confirmed favorable pharmacokinetic profiles and low toxicity, supporting their safety for potential applications. Additionally, density functional theory calculations provided more profound insights into molecular stability and reactivity, including electronic properties such as HOMO-LUMO gaps, further corroborating their pharmacological efficacy. These results collectively indicate that chalcones 1–3 exhibit potent antioxidant activity, adequate UV protection, and promising pharmacokinetic properties. Integrating in vitro, in silico, and DFT analyses underscores their potential as multifunctional compounds for antioxidant and sunscreen applications.

Abstract

ABSTRAKPlastik konvensional telah banyak digunakan dalam kehidupan modern, namun produksinya masih bergantung pada sumber daya fosil yang bersifat non-biodegradable dan berdampak buruk bagi lingkungan. Oleh karena itu, penelitian ini bertujuan untuk mengembangkan SmartClimaPack bioplastik berbahan dasar pati onggok dan selulosa tongkol jagung yang diperkaya minyak atsiri sereh sebagai kemasan aktif biodegradable untuk memperpanjang umur simpan buah klimaterik. Bioplastik dibuat melalui proses ekstraksi minyak sereh dan delignifikasi tongkol jagung, kemudian dikarakterisasi dengan uji kadar air, ketahanan air, biodegradabilitas, dan FTIR. Hasil menunjukkan bahwa bioplastik memiliki kadar air sebesar 15,77%, ketahanan air 91,00%, nilai swelling 9,0%, dan persentase degradasi mencapai 76% dalam 13 hari. Analisis FTIR mengonfirmasi adanya gugus fungsional yang saling berinteraksi melalui ikatan hidrogen pada matriks bioplastik. Dengan demikian, SmartClimaPack berpotensi menjadi kemasan aktif ramah lingkungan yang tidak hanya melindungi produk, tetapi juga memperpanjang umur simpan buah.Kata Kunci: Bioplastik, Pati, Selulosa, SmartClimaPackABSTRACTConventional plastics have been widely used in modern life; however, their production still relies on fossil-based resources that are non-biodegradable and environmentally harmful. Therefore, this study aims to develop SmartClimaPack, a bioplastic derived from cassava starch residue and corn cob cellulose enriched with lemongrass essential oil, designed as an active biodegradable packaging to extend the shelf life of climacteric fruits. The bioplastic was produced through lemongrass oil extraction and corn cob delignification, followed by evaluations of moisture content, water resistance, swelling, biodegradability, and FTIR analysis. The results revealed that the bioplastic exhibited a moisture content of 15.77%, water resistance of 91.00%, swelling value of 9.0%, and biodegradation rate of 76% within 13 days. FTIR analysis confirmed the presence of functional groups interacting through hydrogen bonding within the bioplastic matrix. Thus, SmartClimaPack demonstrates strong potential as an eco-friendly active packaging material that not only provides physical protection but also extends fruit shelf life.
