  • Polyoxypregnane Steroids from the Stems of <i>Marsdenia tenacissima</i>
    作者:Sheng Yao、Kenneth Kin-Wah To、Ya-Zhou Wang、Chun Yin、Chunping Tang、Stella Chai、Chang-Qiang Ke、Ge Lin、Yang Ye
    DOI:10.1021/np500385b
    日期:2014.9.26
    A new polyoxypregnane aglycone, tenacigenin D (1), and seven new C21 steroid glycosides, tenacissimosides D-J (2-8), were isolated from the stems of Marsdenia tenacissima. Their structures were determined by interpretation of their 1D and 2D NMR and other spectroscopic data, as well as by comparison with published values for related known compounds. Compound 1 was found to circumvent P-glycoprotein (P-gp)-mediated multidrug resistance through an inhibitory effect on P-gp with a similar potency to verapamil. In addition, compound 1 potentiated the activity of erlotinib and gefitinib in epidermal growth factor receptor tyrosine kinase inhibitor (EGFR TKI)-resistant non-small-cell lung cancer cells.

    Three new polyoxypregnane glycosides, marsdenosides I–K (1–3), were isolated from the stem of Marsdenia tenacissima. The structures were elucidated on the basis of in-depth spectroscopic analyses, and by means of chemical evidence. Marsdenoside I (= (3β,5α,11α,12β,14β,17α,20R)-3-[(2,6-dideoxy-4-O-(6-deoxy-3-O-methyl-β-D-allopyranosyl)-3-O-methyl-β-D-arabino-hexopyranosyl)oxy]-8,20 : 11,20-diepoxypregnane-12
