SKI3301, a standardized dried 50% ethanolic extracts of Sophora tonkinensis, contains four marker compounds (trifolirhizin, TF; (-)-maackiain, Maack; (-)-sophoranone, SPN, and (2-(2,4-dihydroxyphenyl)-5,6-methylenedioxybenzofuran, ABF), is being developed as an herbal medicine for the treatment of asthma in Korea. This study investigates the pharmacokinetic properties of SKI3301 extract in rats.2. The dose-proportional AUCs suggest linear pharmacokinetics of TF, Maack, SPN and ABF in the SKI3301 extract i.v. dose range of 5-20 mg/kg. After the oral administration of 200-1000 mg/kg of the extract, TF and Maack exhibited non-linearity due to the saturation of gastrointestinal absorption. However, linear pharmacokinetics of SPN and ABF were observed3. The absorptions of TF, Maack, SPN and ABF in the extract were increased relative to those of the resp. pure forms due to the increased solubility and/or the decreased metabolism by other components in the SKI3301 extract4. No accumulation was observed after multiple dosing, and the steady-state pharmacokinetics of TF, Maack, SPN and ABF were not significantly different from those after a single oral administration of the extract5. The pharmacokinetics of TF, SPN and ABF were not significantly different between male and female rats after oral administration of the extract, but a significant gender difference in the pharmacokinetics of Maack in rats was observed6. Our findings may help to comprehensively elucidate the pharmacokinetic characteristics of TF, Maack, SPN and ABF and provide useful information for the clin. application of SKI3301 extract In the experiment, the researchers used many compounds, for example, (2S,3R,4S,5S,6R)-2-(((6aR,12aR)-6a,12a-Dihydro-6H-[1,3]dioxolo[4′,5′:5,6]benzofuro[3,2-c]chromen-3-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 6807-83-6HPLC of Formula: 6807-83-6).
(2S,3R,4S,5S,6R)-2-(((6aR,12aR)-6a,12a-Dihydro-6H-[1,3]dioxolo[4′,5′:5,6]benzofuro[3,2-c]chromen-3-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 6807-83-6) belongs to benzofurans derivatives. Benzofuran is a core structural unit found in many naturally occurring compounds with multidirectional biological activities. As benzofurans are prone to undergo ring opening of the heterocycle, examples of reduction of this type of aromatics by using dissolving metals are rather scarce.HPLC of Formula: 6807-83-6
