수용액에서 수정된 항암 전구약물과 단백질 간의 상호작용

Abstract

We have investigated the interaction of a new water-soluble paclitaxel (7-mPEG5,000-succinyloxymethyloxycarbonyl-paclitaxel, PP7) and hen egg albumin (Mr ~45,000) by pulse-gradient field NMR (PFG-NMR). Diffusion coefficient of PP7 with Albumin in modified Hank's Balanced Salt Solution (MHBSS) was measured as a function of PP7 (0.0~1.7% w/w) and albumin (0.0~1.4% w/w) concentration at different temperatures. This study suggested that the results of molecular mobility and interaction can be used to determine the transport mechanisms in human body liquid
