Description
Sources: https://www.ncbi.nlm.nih.gov/pubmed/7882462

Vinfosiltine (also known as S 12363) was developed as a vinca alkaloid derivative. It is known that vinca alkaloids are widely used in the medical treatment of breast cancer. Vinfosiltine participated in the phase II clinical trial to treat the patients with advanced breast cancer. The results have shown that the drug didn’t have significant single-agent activity. As a result, the development of vinfosiltine was discontinued.
