Additional Information

173937-91-2 (Atrasentan free base).

Atrasentan hydrochloride  is the orally available hydrochloride salt of pyrrolidine-3-carboxylic acid with potential antineoplastic activity. As a selective antagonist of the endothelin-A (ETA) receptor, atrasentan binds selectively to the ETA receptor, which may result in inhibition of endothelin-induced angiogenesis and tumor cell proliferation.
 
Atrasentan is an experimental drug that is being studied for the treatment of various types of cancer, including non-small cell lung cancer. It is an endothelin receptor antagonist selective for subtype A (ETA). While other drugs of this type (sitaxentan, ambrisentan) exploit the vasoconstrictive properties of endothelin and are mainly used for the treatment of pulmonary arterial hypertension, atrasentan blocks endothelin induced cell proliferation.
 
According to http://www.hrpca.org/atrasentan.htm, [Cancer. 2007 Nov 1;110(9):1959-66.] A phase 3 randomized controlled trial of the efficacy and safety of atrasentan in men with metastatic hormone-refractory prostate cancer. Carducci MA, Saad F, brahamsson PA, Dearnaley DP, Schulman CC, North SA, Sleep DJ, Isaacson JD, Nelson JB; for the Atrasentan Phase III Study Group Institutions. Presented at the 40th Annual Meeting of the American Society of Clinical Oncology, New Orleans, Louisiana, June 5-8, 2004. The conclusion states that Atrasentan did not delay disease progression in men with metastatic HRPC despite evidence of biologic effects on PSA and BAP as markers of disease burden.
