20(R)-Ginsenoside Rh2 (cas: 112246-15-8) belongs to tetrahydropyran derivatives. Dihydropyrans and tetrahydropyrans are examples of cyclic ethers widespread in nature. The bismuth chloride-assisted cross-cyclization between homoallylic alcohols and epoxides provided various benzyl tetrahydropyran derivatives. The reaction afforded good yields of desired products and occurred under mild conditions.HPLC of Formula: 112246-15-8

We evaluated the potential of BST204, a purified dry extract of ginseng, to inhibit or induce human liver cytochrome P 450 enzymes (CYPs) and UDP-glucuronosyltransferases (UGTs) in vitro to assess its safety. In vitro drug interactions of four bioactive ginsenosides of BST204, S-Rg3, R-Rg3, S-Rh2, and R-Rh2, were also evaluated. We demonstrated that BST204 slightly inhibited CYP2C8, CYP2D6, CYP2C9, and CYP2B6 activities with IC50 values of 17.4, 26.8, 31.5, and 49.7 渭g/mL, resp. BST204 also weakly inhibited UGT1A1, UGT1A9, and UGT2B7 activities with IC50 values of 14.5, 26.6, and 31.5 渭g/mL, resp. The potential inhibition by BST204 of the three UGT activities might be attributable to S-Rg3, at least in part, as its inhibitory pattern was similar to that of BST204. However, BST204 showed no time-dependent inactivation of the nine CYPs studied. In addition, BST204 did not induce CYP1A2, 2B6, or 3A4/5. On the basis of an in vivo interaction studies, our data strongly suggest that BST204 is unlikely to cause clin. significant drug-drug interactions mediated via inhibition or induction of most CYPs or UGTs involved in drug metabolism in vivo. Our findings offer a clearer understanding and possibility to predict drug-drug interactions for the safe use of BST204 in clin. practice. In the experiment, the researchers used many compounds, for example, 20(R)-Ginsenoside Rh2 (cas: 112246-15-8HPLC of Formula: 112246-15-8).
