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.
通用公式(1)表示的喹唑啉衍生物和作为蛋白激酶抑制剂的喹唑啉配合物,以及它们的制备方法已提供。在通用公式(1)中,R和R′中至少一个是含有能够与贵金属配位的原子的基团,m和n可以相同也可以不同,是从0到5的整数。所述的作为蛋白激酶抑制剂的喹唑啉配合物是由含有贵金属的配合物和所述喹唑啉衍生物配体在配合物中能够与贵金属配位而形成的。作为酪氨酸蛋白激酶抑制剂使用,本发明提供的喹唑啉衍生物和作为蛋白激酶抑制剂的喹唑啉配合物在抑制包括人类乳腺癌细胞系(耐药性)MCF-7/A、人类乳腺癌细胞系(敏感性)MCF-7/S、前列腺癌细胞PC-3、角质细胞Colo-16、人类非小细胞肺癌细胞系A549等各种肿瘤细胞增殖方面表现出良好的抑制作用。
