Different carbon sources lead to differential acarbose production in . To uncover the underlying differentiation in the context of genes and pathways, we performed transcriptome sequencing of ZJB-03852 grown on different saccharides, such as glucose, maltose, or the saccharide complex consisting of glucose plus maltose. The differentially expressed genes were classified into GO (gene ontology) terms and KEGG (Kyoto Encyclopedia of Genes and Genomes) pathways for functional annotations. Key enriched modules were uncovered. Our data revealed that both maltose and its complex with glucose gave improved acarbose titer. Sugar transportation, cytochrome oxidase, protein synthesis and amino acid metabolism modules were enriched under the saccharide complex condition, while ferritin metabolism gene expressions were enriched in the glucose medium. Our results provided the foundation for uncovering the mechanism of carbon source on acarbose production in .

A novel diphenyl-anthraquinone compound, cassuquinone A, was isolated from the rhizomes of Zingiber cassumunar. Structural elucidation was accomplished using detailed NMR and HRMS-ESI techniques, revealing a symmetrical anthraquinone core with methoxylated aromatic rings. Cassuquinone A exhibited potent α-glucosidase inhibitory activity with an IC₅₀ of 11.

Biowaste produced in urban parks is composed of large masses of organic matter that is only occasionally used economically. In this work, extracts of six plants widely distributed in urban parks in Central Europe (, , , , , and ), prepared using 10 % and 50 % ethanol, were screened for their antidiabetic and related properties. HPLC and UV-Vis analysis revealed the presence of caffeic acid, quercetin, luteolin, and apigenin derivatives.

A new modified-release oral formulation combines acarbose and orlistat (MR-OA) to enhance efficacy and reduce adverse effects through controlled drug release. This study aims to compare the pharmacodynamic properties of the orlistat component of MR-OA (MR-O) with a conventional orlistat product, Xenical (Conv-O), analyzing the percentage of fecal fat excretion. In addition, the pharmacokinetic properties of the complete formulation, MR-OA, were compared with Conv-O.
