D-(+)-chiro-Inositol

D-(+)-chiro-Inositol (CAS No.: 643-12-9) is a naturally occurring stereoisomer of inositol and an epimer of myo-inositol that is present in mammalian systems, including glycosylphosphatidylinositol anchors and inositol phosphoglycans with insulin-mimetic signaling properties, making it a valuable small molecule for metabolic and signal transduction research. This compound is widely studied for its role in modulating glucose metabolism and insulin signaling pathways, where it is thought to participate in downstream mediators of insulin action, contributing to the regulation of glucose uptake and glycogen synthesis, as well as influencing key signaling nodes such as NF-κB and cytokine-associated pathways including TNF-α. In experimental systems, D-(+)-chiro-Inositol has demonstrated the ability to reduce markers of oxidative stress and inflammatory signaling, modulate bile acid secretion processes relevant to hepatic function, and influence cellular proliferation and apoptosis in oncology-related models, with reported bioactivity typically observed in the nanomolar to low micromolar concentration range depending on assay conditions. It is frequently utilized in in vitro cell-based assays and in vivo metabolic or endocrine-related animal models to investigate mechanisms underlying insulin resistance, androgen regulation, and inflammatory responses, and has also been included in ongoing clinical research protocols examining inositol stereoisomer combinations. Experimental concentrations and dosing regimens vary according to specific study designs, supporting its application as a biochemical tool in drug discovery, pathway elucidation, and disease model development.
