Comparative permeability of three saikosaponins and corresponding saikogenins in Caco-2 model by a validated UHPLC-MS/MS method

ABSTRACT: Saikosaponins (SSs) are the main active components extracted from Bupleuri Radix (BR) which has been used as an important herbal drug in Asian countries for thousands of years. It has been reported that the intestinal bacteria plays an important role in the in vivo disposal of oral SSs. Although the deglycosylated derivatives (saikogenins, SGs) of SSs metabolized by the intestinal bacteria are speculated to be the main components absorbed into the blood after oral administration of SSs, no studies have been reported on the characteristics of SGs for their intestinal absorption, and those for SSs are also limited. Therefore, a rapid UHPLC-MS/MS method was developed to investigate and compare the apparent permeability of three common SSs (SSa, SSd, SSb2) and their corresponding SGs (SGF, SGG, SGD) through a bidirectional transport experiment on Caco-2 cell monolayer model. The method was validated according to the latest FDA guidelines and applied to quantify the six analytes in transport medium samples extracted via liquid-liquid extraction (LLE). The apparent permeability coefficient (Papp) determined in this study indicated that the permeability of SGs improved to the moderate class compared to the corresponding parent compounds, predicting a higher in vivo absorption. Moreover, the efflux ratio (ER) value demonstrated an active uptake of SSd and the three SGs, while a passive diffusion of SSa and SSb2. Graphical abstract Image 1 Highlights • A permeability model of Caco-2 cell monolayer was established and validated.• An UHPLC-MS/MS method was developed for 3 saikosaponins and their saikogenins.• The permeability of SSa, SSb2 and SSd improved after in vivo deglycosylation.• Transport mechanism: Active uptake of SSd or SGs, passive diffusion of SSa or SSb2.

Project description:An accurate and precise liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) method was developed and validated for the pharmacokinetic study of epiprogoitrin and progoitrin, a pair of epimers that can be deglycosylated to epigoitrin and goitrin, respectively. These analytes were administered intravenously or intragastrically to male Sprague-Dawley rats, and the influence of 3(R/S)-configuration on the pharmacokinetics of both epimers in rat plasma was elucidated. The analytes and an internal standard (i.e., sinigrin) were resolved by LC-MS/MS on a reverse-phase ACQUITY UPLC™ HSS T3 column equilibrated and eluted with acetonitrile and water (0.1 % formic acid) at a ?ow rate of 0.3?mL/min. Quantitation was achieved by applying the multiple reaction monitoring mode, in the negative ion mode, at transitions of m/z 388 ? 97 and m/z 358 ? 97 for the epimers and sinigrin, respectively. The method demonstrated good linearity over the concentration range of 2-5000?ng/mL (r > 0.996). The lower limit of quantification for epiprogoitrin and progoitrin was 2?ng/mL. The interday and intraday accuracy and precision were within ±15 %. The extraction recovery, stability, and matrix effect were demonstrated to be within acceptable limits. The validated method was thus successfully applied for the pharmacokinetic study of both the epimers. After the rats received the same oral dose of the epimers, the pharmacokinetic profiles were similar. The maximum plasma concentration (Cmax) and AUC values of epiprogoitrin were a bit higher than those of progoitrin, whereas the pharmacokinetic behaviours of the epimers were obviously different upon intravenous administration. The Cmax and AUC values of epiprogoitrin were approximately three-fold higher than those of progoitrin, and the half-life of progoitrin was much shorter than that of epiprogoitrin. The oral bioavailability of progoitrin was 20.1 %-34.1 %, which is three times higher than that of epiprogoitrin.
