  • Quinazoline derivatives and quinazoline complex protein kinase inhibitor for inhibiting multiplication of tumor cells and preparation method thereof
    Patent number: 9233995
    Abstract: Quinazoline derivatives represented by general formula (1) and quinazoline complexes as protein kinase inhibitors, and their preparation methods are provided. Wherein, in general formula (1), at least one of R and R? is a group containing an atom capable of coordinating with noble metals, m and n are either the same or different and are integers from 0 to 5. Said quinazoline complex as protein kinase inhibitor is formed by coordination compound containing noble metal and said quinazoline derivative ligand capable of coordinating with noble metal in the coordination compound.
