Description: AZD6126, also known as ANG-453, a water-soluble phosphate prodrug of N-acetylcolchinol with potential antiangiogenesis and antineoplastic activities. AZD-6126 is an angiogenesis inhibitor and tubulin inhibitor potentially for the treatment of solid tumours. AZD6126 is converted in vivo into N-acetylcolchinol. N-acetylcolchinol binds to and destabilizes the tubulin cytoskeleton of endothelial cells in tumor blood vessels, which may result in tumor endothelial cel apoptosis, the selective occlusion of tumor blood vessels, cessation of tumor blood flow, and tumor necrosis.

Additional Information

A phase I clinical trial identified gastrointestinal and cardiac effects as limiting dosing. Two phase II clinical trials were started investigating ZD6126 in metastatic renal cell carcinoma and metastatic colorectal cancer.ZD6126 was being investigated by AstraZeneca as a VDA (vascular disrupting agent). However, the trials were halted, after it became apparent that ZD6126 was too cardiotoxic at the required doses. [source:].
