Abstract

Diabetes mellitus remains a major global health challenge, prompting the exploration of natural products as sources of safer antidiabetic agents. This study aimed to identify bioactive compounds from the roots of Acalypha indica and evaluate their potential as inhibitors of glutamine–fructose-6-phosphate amidotransferase (GFAT), an enzyme involved in glucose metabolism. Compound profiling was conducted using liquid chromatography–high resolution mass spectrometry (LC-HRMS), while the inhibitory potential against GFAT was assessed through in silico docking. This integrated approach has not been previously reported. Metabolite profiling using LC-HRMS tentatively identified thirteen carboxylic acid derivatives, including hydroxycinnamic acid, gluconic acid, trans-aconitic acid, and glucoheptonic acid. molecular docking analysis revealed strong binding affinities of several compounds toward GFAT.  Glucoheptonic acid exhibited the lowest binding energy (−8.0 kcal/mol), followed by xylaric acid A (−7.9 kcal/mol) and trans-aconitic acid (−7.5 kcal/mol). These compounds interacted with key active-site residues Gln421, Ser420, Ser422, and Lys675, suggesting a potential enzyme inhibition mechanism. In silico pharmacokinetic analysis indicated that 2-hexylpentanedioic acid exhibited favorable ADME properties, with high gastrointestinal absorption, no major inhibition of CYP450, and low predicted acute toxicity risk. These findings highlight Acalypha indica roots as a promising source of bioactive carboxylic acid derivatives, with glucoheptonic acid emerging as the most promising candidate for further in vitro evaluation as a GFAT inhibitor

Abstract

Kitosan, biopolymer kationik alami dari deasetilasi kitin eksoskeleton hewan laut, memiliki sifat biokompatibilitas, biodegradabilitas, dan non-toksisitas yang menarik untuk berbagai aplikasi. Penelitian ini bertujuan untuk mengkarakterisasi kitosan yang diisolasi dari limbah cangkang sotong yang diperoleh dari Pantai Tanjung Kramat, Kota Gorontalo dengan focus rendemen, kadar air, dan analisis Fourier Transform Infrared (FITR). Proses isolasi melibatkan tahap demineralisasi, deproteinasi, dan deasetilasi. Hasil penelitian menunjukkan rendemen kitosan tertinggi 28% pada perlakuan HCl 5%, sedangkan kadar air seluruh sampel berkisar antara 2,00-2,21% dan memenuhi standar SNI 7949:2013 (?12%). Analisis FTIR mengidentifikasi gugus fungsi utama dan derajat deasetilasi (DD) tertinggi mencapai 80,17% pada perlakuan HCl 7%, memenuhi standar mutu (?75%). Penelitian ini memberikan wawasan penting mengenai potensi cangkang sotong sebagai sumber kitosan berkualitas.
