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)
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；分子内局部能量极小值越大,对渗透越有利；在一定范围内体积大且球形性高的分子对渗透有利....
