Description
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/8632312

Atrasentan (ABT-627, A-127722) is a selective endothelin A receptor antagonist. Atrasentan is being developed by AbbVie as an oral treatment for diabetic nephropathies.Abbott Laboratories was conducting clinical development of atrasentan for the treatment of certain cancers, including phase II trials for prostate cancer. However, no recent development has been reported for cancer indications and development is presumed to be discontinued.

CNS Activity

Curator's Comment: No significant binding was observed in mouse brain or heart after intravenous injection of atrasentan (ABT-627, A-127722). However it was shown that the drug partially normalized the infarct volume and neurological deficit in animal models of cerebral ischemia and attenuated tactile allodynia in a diabetic rat model of neuropathic pain. In addition phase I safety study of atrasentan was conducted in adults with recurrent malignant glioma.
