Description: Tasquinimod, also known as ABR215050, is a quinoline-3-carboxamide linomide analogue with antiangiogenic and potential antineoplastic activities. Tasquinimod has been shown to decrease blood vessel density but the exact mechanism of action is not known. This agent has also been shown to augment the antineoplastic effects of docetaxel and androgen ablation in a murine model of prostate cancer involving human prostate cancer xenografts.

Additional Information

The orally active quinoline-3-carboxamide tasquinimod [ABR-215050; CAS number 254964-60-8), which currently is in a phase II-clinical trial in patients against metastatic prostate cancer, exhibits anti-tumor activity via inhibition of tumor angiogenesis in human and rodent tumors. Tasquinimod-induced up-regulation of TSP1 is part of a mechanism involving down-regulation of HIF1alpha and VEGF, which in turn leads to reduced angiogenesis via inhibition of the "angiogenic switch", that could explain tasquinimods therapeutic potential. see: http://www.ncbi.nlm.nih.gov/pubmed/20470445.
