在药物定量构效关系(QSAR)研究中,利用反相高效液相色谱法(RP-HPLC)保留值代替正辛醇-水分配系数logP_(ow)已有许多报道。但RP-HPLC保留值与logP_(ow)之间的相关性仅限于同类化合物(congeneric compounds)。对于疏水性强的化合物经常需要在流动相中加入有机改性剂,然而增高有机改性剂的浓
In QSAR studies, there have been many reports of using reversed-phase high performance liquid chromatography (RP-HPLC) retention values instead of n-octanol-water partition coefficient logP ow. However, the correlation between RP-HPLC retention and logP_ (ow) is limited to congeneric compounds. For hydrophobic compounds often need to be added to the mobile phase of organic modifier, but increase the concentration of organic modifier
