| Description | Tenacigenin B is a natural product of Marsdenia, Asclepiadaceae. The catalog number is TN2263 and the CAS number is 80508-42-5. Tenacigenin B can be used as a reference standard. |
| In vitro | Tenacissimoside A (1) and 11alpha-O-benzoyl-12beta- O-acetylTenacigenin B (2), two derivatives of Tenacigenin B (3) from the plant Marsdenia tenacissima, reversed multidrug resistance in P-glycoprotein (Pgp)-overexpressing multidrug-resistant cancer cells. The sensitivity of HepG2/Dox cells to the antitumor drugs doxorubicin, vinblastine, puromycin, and paclitexel was increased by 18-, 10-, 11-, and 6-fold by 20 microg/mL (or 25 microM) of 1 and 16-, 53-, 16-, and 326-fold by 20 microg/mL (or 39 microM) of 2, respectively[1] |
