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. Used as tyrosine protein kinase inhibitors, Quinazoline derivatives and quinazoline complexes as protein kinase inhibitors provided by the present invention have exhibited good inhibitory effect on proliferation of various tumor cells including human breast cancer cells line (drug-resistant) MCF-7/A, human breast cancer cell line (sensitive) MCF-7/S, prostate cancer cell PC-3, keratinocytes Colo-16, human non-small cell lung cancer cell line A549, etc.
