Abstract

Oxidative stress, resulting from imbalance between rective oxygen species (ROS) production and antioxidant defenses, contributes significantly to numerous pathological conditions, including inflammation, cancer and neurodegeneration. Natural compounds with antioxidant properties offer promising therapeutic potential. This study aims to investigate the potential of Cucurbitacin IIa and IIb to modulate oxidative stress regulatory proteins (NOS2, Lipoxygenase, KEAP1, and Xanthine oxidase) using molecular docking approaches. Target protein structures were retrieved from the RSCB Protein Data Bank. Ligand geometries were constructed and optimized using density functional theory. Molecular docking was performed using AutoDock 1.5.6 with a validated docking protocol (RPMS<2Å). Our results demonstrated favorable binding energies for both compounds with NOS2 (-9.75 and -9.57 kcal/mol) and KEAP1 (-8.52 and -9.34 kcal/mol), approaching the affinities of their respective native ligands. Moderate binding was observed with Lipoxygenase (-6.14 and -5.54 kcal/mol), while both compounds showed incompatibility with Xanthine oxidase, as evidenced by highly positive binding energies. The interaction between Cucurbitacins with NOS2, KEAP1 and Lipoxygenase was mediated through hydrogen and hydrophobic interaction. These findings provide mechanistic insight into their bioactivity and support further experimental studies for therapeutic development in oxidative stress-related disorders.Keywords: Cucurbitacin, Molecular docking, Oxidative stress, NOS2, KEAP1.

Abstract

Tuberculosis (TB) is a contagious disease caused by Mycobacterium tuberculosis. Isoniazid, a synthetic antimicrobial agent, remains one of the most crucial first-line medications in TB therapy. Enhancing TB treatment strategies can be achieved through structural modifications of existing drugs. This study investigates the potential of isoniazid derivatives as anti-tuberculosis agents targeting the CYP3A4 protein complexed with a small-molecule inhibitor (PDB ID: 6MA8) and evaluates their toxicity profiles using in silico methods. The ligands analyzed include isoniazid derivatives 1–5, with isoniazid as a reference compound and protoporphyrin as the native ligand. The structure of ligands was prepared using Avogadro software and optimized with ORCA software. The crystal structures of 6MA8 were retrieved from the PDB database and further validated using YASARA. In silico methods such as molecular docking and ProTox prediction were employed to evaluate the potential of these isoniazid derivatives as anti-TB drugs. The interactions were visualized using Biovia Discovery to assess the interaction between the isoniazid derivatives and the receptor. The results showed derivative 4 exhibited the lowest binding affinity (-71.56 kcal/mol) compared to isoniazid (-65.90 kcal/mol), derivative 1 (-63.65 kcal/mol), derivative 2 (-67.01 kcal/mol), derivative 3 (-67.37 kcal/mol), derivative 5 (-69.02 kcal/mol), and native ligand (-182.68 kcal/mol). Biovia Discovery Studio simulations indicated that the isoniazid derivatives interacted with 6MA8 via conventional hydrogen bonds, carbon-hydrogen bonds, and other interactions. The toxicity analysis showed that the derivatives had safe LD50 values, supporting their safety profiles. These results suggest that isoniazid derivatives have promising potential as anti-tuberculosis agents targeting 6MA8.

Abstract

Environmental concerns related to the extensive use of conventional organic solvents have driven the development of greener extraction technologies, including the application of deep eutectic solvents (DES) as environmentally friendly alternatives. This study aimed to evaluate the effectiveness of choline chloride–based DES combined with glycerol and propylene glycol as green solvents for anthocyanin extraction from Senduduk flowers (Melastoma sp.) using the ultrasound-assisted extraction (UAE) method. DES were synthesized at a 1:2 molar ratio and characterized based on density, viscosity, pH, moisture content, and functional group analysis using FTIR spectroscopy. The results confirmed the successful formation of DES with suitable physicochemical properties for extraction applications. Both DES systems were able to extract various bioactive compounds, including flavonoids, alkaloids, terpenoids, saponins, and tannins. The highest total anthocyanin content was obtained using choline chloride/glycerol DES (93.29 mg/L), followed by choline chloride/propylene glycol DES (89.06 mg/L). Total flavonoid contents were 86.97 mg QE/g and 85.78 mg QE/g, respectively. Antioxidant activity analysis indicated strong radical scavenging capacity with IC₅₀ values of 70.82 ppm and 72.61 ppm. These findings demonstrate that glycerol- and propylene glycol-based DES are effective green solvents for anthocyanin extraction and show potential for sustainable applications in food, pharmaceutical, and cosmetic industries.

Abstract

Desa Kalisari, Kecamatan Natar, memiliki jumlah penerima Program Keluarga Harapan (PKH) yang tinggi, di mana sebagian penerima telah mengembangkan usaha mikro berbasis rumah tangga. Meskipun demikian, UMKM tersebut masih menghadapi kendala terkait legalitas usaha dan sertifikasi halal yang menghambat pemasaran, kemitraan, serta akses ke pasar digital. Studi awal mengidentifikasi tiga masalah utama, yaitu rendahnya pengetahuan teknis mengenai bahan baku dan keamanan produk, ketidaktahuan prosedur perizinan dan pengajuan sertifikasi halal, serta kurangnya kolaborasi dengan lembaga pendukung. Untuk mengatasi hal tersebut, tim pelaksana telah menyiapkan modul dan melakukan koordinasi dengan mitra. Kegiatan yang akan dilaksanakan mencakup identifikasi UMKM sasaran, pelatihan teknis dan administrasi, pendampingan penyusunan dokumen legalitas dan sertifikasi halal, memfasilitasi ke instansi terkait, serta monitoring dan evaluasi. Program ini mendukung pencapaian SDG 8 dan SDG 12, serta bertujuan meningkatkan kapasitas UMKM PKH agar lebih kompetitif dan berdaya saing. Melalui kegiatan ini, kualitas UMKM lokal diharapkan meningkat sehingga mampu bersaing pada tingkat regional maupun nasional.

Abstract

Acne vulgaris is a common skin disorder caused by clogged pores and infection by Propionibacterium acnes. The use of synthetic chemicals in skincare products often leads to side effects, highlighting the need for safer and eco-friendly natural alternatives. Natural zeolite, particularly Lampung Natural Zeolite (ZAL), has potential as an antibacterial agent due to its porous structure and adsorption capacity. This study evaluates the effectiveness of ZAL as an active ingredient in clay mask formulations against P. acnes. ZAL was activated and purified, then formulated into masks with varying concentrations (2.5 g, 5 g, and 7.5 g). Characterization was conducted using IR, XRD, and SEM, while antibacterial activity was tested using the agar diffusion method. Activation improved crystallinity and increased silanol (Si–OH) groups, enhancing antibacterial performance. The 5 g zeolite formulation showed the largest inhibition zone, indicating optimal effectiveness. Overall, ZAL demonstrates strong potential as a natural antibacterial agent for facial mask products.
