Patent Searching and Data

Document Type and Number:
WIPO Patent Application WO/2018/121465
Kind Code:
Diphosphino metallic complexes, methods of making and using are described. The complexes display cytotoxicity against a panel of cancer cell lines, and optionally display luminescent properties. They have improved solubility and are stable against hydrolysis in physiologically reducing conditions. In some aspects, the complexes are iridium (III) diphosphine complexes. The compounds and pharmaceutical compositions thereof can be administered to a subject in need thereof to treat a host of diseases and disorders including but not limited to, proliferative disorders such as cancer.
