Displaying 3 results of Tivozanib Stable Isotopes Tivozanib is a potent and selective inhibitor of vascular endothelial growth factor receptors (VEGFRs) 1, 2, and 3. Stable isotopes of Tivozanib are chemically identical to the naturally occurring isotopes but have a different number of neutrons in their nuclei, resulting in unique physical and chemical properties. These isotopes are used in various research applications, including drug development and pharmacokinetics studies, to track the fate and metabolism of the drug in biological systems.
