Iron Dextran

Iron Dextran (CAS No.: 9004-66-4) is a polymeric iron carbohydrate complex broadly categorized as a hematology related research reagent and micronutrient delivery model compound that is used in biomedical investigations of iron homeostasis, erythropoiesis, and experimentally induced iron deficiency states, particularly in preclinical and veterinary oriented settings where controlled iron repletion paradigms are required for mechanistic study. In biological systems, its functional background is linked to reticuloendothelial uptake and intracellular processing of complex bound iron, followed by gradual release to transferrin associated trafficking pathways, thereby influencing canonical iron regulatory networks that involve the hepcidin ferroportin axis, transferrin receptor dependent iron acquisition, ferritin mediated storage dynamics, and downstream modulation of hypoxia responsive and redox sensitive signaling programs under iron limited or iron reconstituted conditions. Consistent with its mode of action as an iron source rather than a selective receptor ligand, well standardized single target affinity constants and conventional small molecule potency metrics such as IC50 or EC50 are generally not reported in a directly comparable format, and in vitro response windows are therefore more appropriately described by formulation and context dependent concentration ranges that are commonly explored from low micromolar to higher micromolar or millimolar equivalent iron exposure in cell based assays designed to evaluate iron uptake kinetics, oxidative stress balance, mitochondrial function, or differentiation related hematopoietic endpoints. Typical research applications include use in cultured macrophage, hepatocyte, and erythroid lineage models to interrogate iron handling biology, as well as use in animal models of iron deficiency anemia for studying hematologic recovery trajectories, biomarker shifts, and pharmacology of iron replacement strategies, while experimental concentrations or doses are selected according to species, matrix, route, and specific study objectives in discovery, translational, and comparative pharmacology workflows.
