摘要
Abstract
Objective The ultrafiltration was employed to determine the human plasma protein binding ratio of a novel Caspase inhibitor F1013. The influence factors of this determination were investigated. Methods The unbound fractions in plasma were separated with ultrafiltration equipment under different conditions and were determined with high performance liquid chromatography (HPLC). Results The Amicon Ultra-0.5 equipment was suitable for researching the plasma protein binding ratio of F1013. The plasma protein binding ratio of F1013 was increased with the increasing of rotation speed and centrifuge time, and it was decreased with prolongated incubation time. Conclusion Human plasma protein binding ratio of F1013 was influenced by rotation speed, centrifuge time and incubation time. When the ultrafiltration was applied to study the human plasma protein binding ratio of F1013, the best ultrafiltration conditions are that the human plasma spiked with F1013 was incubated in the 37 ℃ water for 1 h, and then put into the Amicon Ultra-0. 5 equipment, to centrifuge at 14 000 r · min~ for 15 min. The method has satisfying recovery, precision, and a good feasibility.关键词
