Featured are methods and compositions for treating, managing, preventing, or reducing injury to the kidney of a mammal (e.g., a human) caused by one or more iodinated radiocontrast media. The methods include administering an effective amount of one or more pituitary adenylate cyclase-activating polypeptide (PACAP)-like compounds, which includes native human PACAP38, native human PACAP27, native human vasoactive intestinal peptide (VIP), their agonists, analogs, fragments, and derivatives, with activities toward one or more of the PACAP/VIP receptors, including all of their various isoforms. Also provided are pharmaceutical compositions of one or more PACAP-like compounds, either alone or in combination with one or more other prophylactic/therapeutic agents useful for treating, managing, or preventing injury to the kidney of a mammal (e.g., a human) undergoing treatment with one or more iodinated radiocontrast media. Also featured is an in vivo mouse model for testing the efficacy of cytoprotective agents against contrast-induced nephropathy.

Use of pituitary adenylate cyclase-activating polypeptide (PACAP) and PACAP analogs for treating contrast-induced nephropathy

This invention relates to novel analogs of pituitary adenylate cyclase-activating polypeptide (PACAP), which are agonists for the PACAP/vasoactive intestinal peptide (VIP) receptors: PAC1, VPAC1 and VPAC2 receptors. These PACAP analogs can be used as prophylactic/therapeutic agents for a wide range of medical disorders, including (but not limited to) cancer and autoimmune disease. These PACAP analogs can be coupled to suitable radionuclides and used in the localization, diagnosis and treatment of disseminated cancers and metastatic tumors, or coupled to small molecule therapeutics and used as vectors for targeted drug delivery. This invention also provides pharmaceutical compositions of one or more PACAP-like compounds of the invention either alone or in combination with one or more other prophylactic/therapeutic agents.
