NCIt synonyms : Endothelin B Receptor Agonist SPI-1620;
NCIt definition : A highly selective peptide agonist of the endothelin-B receptor. Sovateltide binds
to endothelin-B receptors on endothelial cells in tumor blood vessels, which, unlike
the angioarchitecture of normal blood vessels, are relatively devoid of smooth muscle.
This agent may induce a transient, selective increase in blood flow to a tumor, which
may result in an increase in the delivery of anticancer agents to the tumor and, so,
an increase in anticancer agent efficacy.;
