- Indole ketone compound or its derivatives and their use
-
The present invention relates to indolone compounds shown by general formula (a) or derivatives thereof, and uses thereof. The technical problem solved by the present invention is to provide indolone compounds or derivatives thereof, and uses thereof. The present invention uses a deuterium-enriched indolone compound obtained from a deuterium-substituted indolone compound. The above-mentioned indolone compounds can simultaneously effect on three key receptor families involved in the process of blood vessel formation, i.e., vascular endothelial growth factor receptor (VEGFR), fibroblast growth factor receptor (FGFR), and platelet-derived growth factor receptor (PDGFR), and inhibit the formation of blood vessel, thereby achieving the effect of treating cancers. The above-mentioned deuterium-substituted indolone compounds or derivatives thereof have the advantage of high efficiency as medicaments.
