Gadodiamide

Gadodiamide (CAS No.: 131410-48-5) is a gadolinium-based contrast agent widely used in biomedical research, particularly in magnetic resonance imaging (MRI). As a reagent that helps enhance visual contrast in blood vessels, gadodiamide plays an important role in improving imaging resolution in a variety of biological studies. This compound belongs to the category of nonionic linear chelates, and its applications extend to various in vitro and in vivo models, helping to accurately reveal vascular and physiological phenomena. Although specific experimental data on this compound in the public domain, such as IC50 or EC50 values, are limited, its analogs exhibit biological activity in the nanomolar to low micromolar range. In experimental research, gadodiamide is typically used at concentrations adapted to specific research objectives and methods, especially in mouse or cell models. This compound primarily enhances signal intensity by altering the local magnetic field, playing a key role in imaging applications. Extensive research continues to explore its potential in drug discovery, highlighting the utility of gadodiamide in preclinical studies that require precise image-guided analysis of biological mechanisms.
