QSPR study and three-dimensional descriptor characterization of membrane-water partition coefficient of compounds(化合物膜水分配系数的QSPR研究和分子三维参数表征)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2005
利用多元线性回归和偏最小二乘分析方法,研究分子表面静电势参数,VolSurf参数与双十四酰基磷脂酰基胆碱(DMPC)-水分配系数之间的定量结构-性质关系(QSPR),均得到较好的结果.分子表面静电势参数分析表明化合物分子表面上负的静电势越分散,越倾向于分配在水相中;与水分子的作用越强,越有利于分配在水相中.此外,具有较大体积和偶极密度的分子倾向于分配在弱极性相中.VolSurf参数分析表明大体积的分子易于分配在DMPC中;分子表面亲水区域较大的分子则倾向于分配在水相中 ...

QSPR Study on the permeability of drugs across Caco-2 monolayer(药物对Caco-2单细胞层穿透性的QSPR研究)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2009
Caco-2单细胞层用于模拟或预测体内小肠吸收均较剥离的小肠膜效果好.利用偏最小二乘分析方法研究Vol Surf参数与药物透过Caco-2单细胞层的渗透系数之间的定量结构-性质关系(QSPR),得到较好的结果(r2 = 0.95,q2=0.75).对其它类药物的预测结果表明,用结构不同的化合物所建立的模型对肽类药物以及同系物分子均有一定的预测能力,但是当分子的柔性键多,可能形成分子内氢键时,模型的预测能力大大下降.参数分析表明对Caco-2单细胞层渗透性高的药物分子必须具有合适的氢键给体和受体 ...
