The present invention provides an application of hydroxybenzene salicylamine hydroxide in the preparation of antineoplastic drugs. The tumors of the invention are human liver cancer, human colon cancer, human breast cancer, human prostate cancer, human stomach cancer and human lung cancer. The hydroxyphenylsalicylamine hydroxylate provided by the invention is a drug molecule with inhibitory effect on RR enzyme, and has certain anti-tumor activity. Based on the crystal structure and computer-aided virtual screening, we found that the hydroxyl compound of hydroxyphenylsalicylamine can inhibit RR enzyme. The structure formula of the hydroxyl compound of hydroxyphenylsalicylamine is as follows:

羟苯水杨胺羟基化物在制备抗肿瘤药物中的应用
本专利技术属于制药领域,涉及一种羟苯水杨胺羟基化物在制备抗肿瘤药物中的应用。
技术介绍
核糖核苷酸还原酶(Ribonucleotidereductase,RR)是人体细胞DNA合成和修复的关键酶,其功能是将核糖核苷酸(Ribonucleotidetriphosphates,NDPs)还原为脱氧核糖核苷酸(Deoxyribonucleotidetriphosphates,dNDPs),后者进一步被激酶磷酸化为dNTPs,为DNA合成提供原料。RR酶的结构包括两个相同的大亚基(ribonuclotidereductaselargesubunitM1,RRM1)和两个相同的小亚基(ribonuclotidereductasesmallsubunitM2orM2B,RRM2或RRM2B)。RRM1包含催化位点和两个别构调节位点,RRM2和RRM2B包含一个双铁酪氨酰自由基中心。RR三种亚基分别组成两类RR酶,即RRM1-RRM2和RRM1-RRM2B。RRM1-RRM2主要为增殖细胞的基因组DNA复制提供dNDPs。RRM1-R ...
