The determination of in vitro pingyangmycin hydrochloride plasma protein binding by microdialysis.
Microdialysis sampling was used to study the binding of pingyangmycin hydrochloride (PYM) to plasma proteins in canis familiaris blood. In vitro plasma protein binding fractions were evaluated in a series of PYM concentration. The results showed decreased protein binding with increased concentration. The data was analyzed using the Scatchard analysis and Klotz plot. The results showed that the Scatchard plot and Klotz plot were linear with good correlation coefficient, indicating a good agreement of the experimental data to the theoretical equation.
