Metabolic basis of solute carrier transporters in treatment of type 2 diabetes mellitus

Solute carriers(SLCs) constitute the largest superfamily of membrane transporter *** transporters, present in various SLC families, play a vital role in energy metabolism by facilitating the transport of diverse substances, including glucose, fatty acids, amino acids, nucleotides, and *** actively participate in the regulation of glucose metabolism at various steps, such as glucose uptake(e.g., SLC2A4/GLUT4), glucose reabsorption(e.g., SLC5A2/SGLT2), thermogenesis(e.g., SLC25A7/UCP-1), and ATP production(e.g., SLC25A4/ANT1 and SLC25A5/ANT2). The activities of these transporters contribute to the pathogenesis of type 2 diabetes mellitus(T2DM). Notably, SLC5A2 has emerged as a valid drug target for T2DM due to its role in renal glucose reabsorption, leading to groundbreaking advancements in diabetes drug discovery. Alongside SLC5A2, multiple families of SLC transporters involved in the regulation of glucose homeostasis hold potential applications for T2DM therapy. SLCs also impact drug metabolism of diabetic medicines through gene polymorphisms, such as rosiglitazone(SLCO1B1/OATP1B1) and metformin(SLC22A1-3/OCT1-3 and SLC47A1, 2/MATE1, 2). By consolidating insights into the biological activities and clinical relevance of SLC transporters in T2DM, this review offers a comprehensive update on their roles in controlling glucose metabolism as potential drug targets.

Gastrointestinal distribution and in vitro-microbial biotransformation of chlorogenic acid

Food science and Human Wellness 2024年

作者： Yunhui Zhang Bowei Zhang Xiaoxia Liu Xiang Li Fan Wei Lingda Zhao Huan Lü Xudong Wang Jin Wang Jing Wu Yan Zhang Shuo Wang Tianjin Key Laboratory of Food science and health， school of medicine， Nankai university College of Pharmaceutical science， Zhejiang university of Technology

Chlorogenic acid (CGA)， as a polyphenol abundant in daily diet， exerted various intestinal functions. However， the material basis of its intestinal bioactivities was still unclear. Our study investigated the gastrointestinal distribution of CGA using UPLC-MS/MS and explored the main drivers leading to different metabolic fates of the metabolites. After oral administration of 50 mg/kg bw CGA to mice， CGA and sulfated metabolites were mainly determined in small intestine. Protocatechuic acid， catechol， and 3-hydroxyphenylpropionic acid were found in copious amounts in large intestine and feces. Besides， caffeic acid existed in the entire intestine and feces. In the in vitro mice/human fecal fermentation of CGA， the production of metabolites was consistent with that in the colon， indicating that microorganisms might lead to the difference in the gastrointestinal distribution of CGA metabolites. Moreover， CGA， 3-hydroxyphenylpropionic acid， protocatechuic acid， catechol， and caffeic acid reduced proinflammatory cytokines (IL-6 and TNF-α) and increased mucin (Muc2) and tight junction (occludin) mRNA in LPS-induced Caco-2/HT-29 MTX co-culture cells. In conclusion， the biotransformation of CGA in different gastrointestinal tracts varied significantly， and its metabolites could partially support its intestinal bioactivities.
