【摘要】:葡萄糖激酶GK是調(diào)節(jié)體內(nèi)葡萄糖代謝和參與血糖動(dòng)態(tài)平衡的主要靶點(diǎn)之一。本文針對(duì)46個(gè)具有GK激動(dòng)劑活性的吡啶類衍生化合物進(jìn)行構(gòu)效關(guān)系研究,研究了其結(jié)構(gòu)與活性的關(guān)系;诜肿庸餐羌墀B合用分子力場(chǎng)分析法(COMFA),比較分子相似指數(shù)法(COMSIA)兩種經(jīng)典三維定量構(gòu)效關(guān)系(3D-QSAR)方法,建立相應(yīng)模型,進(jìn)行分子結(jié)構(gòu)和抗糖尿病活性分析。COMFA模型的交叉驗(yàn)證系數(shù)q~2為0.613,相關(guān)系數(shù)r~2為0.989;COMSIA模型交叉驗(yàn)證系數(shù)q~2為0.621,相關(guān)系數(shù)r~2為0.982。數(shù)據(jù)證明兩種模型都顯示出較好的預(yù)測(cè)性,為設(shè)計(jì)新的活性更高的小分子激動(dòng)劑提供了可靠信息。
[Abstract]:Glucokinase GK is one of the main targets to regulate glucose metabolism and to participate in the homeostasis of blood glucose. The structure-activity relationships of 46 pyridine derivatives with GK agonist activity were studied. Based on the comparison of molecular similarity index method (COMSIA) and three dimensional quantitative structure-activity relationship (3D-QSAR) method by molecular force field analysis (COMFA), the corresponding model was established based on the molecular common skeleton superposition. The molecular structure and antidiabetic activity were analyzed. The cross validation coefficient of COMFA model was 0.613, and the correlation coefficient was 0.989; The cross validation coefficient of COMSIA model was 0. 621, and the correlation coefficient was 0. 982. The data show that both models show good predictability and provide reliable information for the design of new and more active small molecular agonists.
