Bioactivity inspired C19-diterpenoid alkaloids for overcoming multidrug-resistant cancer was written by Wada, Koji;Goto, Masuo;Ohkoshi, Emika;Lee, Kuo-Hsiung;Yamashita, Hiroshi. And the article was included in Journal of Natural Medicines in 2022.Recommanded Product: 2,2′,2”,2”’-(((3′,6′-Dihydroxy-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-2′,7′-diyl)bis(methylene))bis(azanetriyl))tetraacetic acid This article mentions the following:

The pharmacol. activities of C19-diterpenoid alkaloids are related to their basic skeletons (e.g., aconitine-type or lycoctonine-type). Also, few studies have been reported on the chemosensitizing effects of diterpenoid alkaloids. Consequently, this study was aimed at determining the chemosensitizing effects of synthetic derivatives of lycoctonine-type C19-diterpenoid alkaloids on a P-glycoprotein (P-gp)-overexpressing multidrug-resistant (MDR) cancer cell line KB-VIN. The acyl-derivatives of delpheline and delcosine showed moderate cytotoxicity against chemosensitive cancer cell lines. Among non-cytotoxic synthetic analogs (1-14), several derivatives effectively and significantly sensitized MDR cells by interfering with the drug transport function of P-gp to three anticancer drugs, vincristine, paclitaxel, and doxorubicin. The chemosensitizing effect of derivatives 2, 4, and 6 on KB-VIN cells against vincristine were more potent than 5 μM verapamil, and derivatives 4 and 13 were more effective than 5 μM verapamil for paclitaxel. Among them, 2 in particular increased the sensitivity of KB-VIN cells to vincristine by 253-fold.
