Pharmacology

Indication

Investigated for use/treatment in cancer/tumors (unspecified).

Pharmacodynamics

In animal models SPI-1620 selectively and transiently increases tumor blood flow allowing increased delivery of anticancer agents to the tumor.

Mechanism of action

SPI-1620 is a highly selective peptide agonist of endothelin-B receptors, which can stimulate receptors on endothelial cells, the innermost layer of cells lining the blood vessels. The blood supply to tumors is different than the blood supply to healthy organs. Blood vessels in the growing part of tumors are relatively devoid of smooth muscle covering and are rich in endothelial cells. Therefore, by stimulating the endothelial-B receptors present on the endothelial cells, SPI-1620 should selectively increase tumor blood flow while sparing healthy tissue.
