标题:Cardiac Glycosides From The Bark Of Antiaris Toxicaria
摘要:Five New Cardiac Glycosides (1-5,Namely Antiaroside Y-Zc) Together With 19 Known Compounds Were Obtained From The Bark Of Antiaris Toxicaria. Their Chemical Structures Were Determined By Ir,Hr-Esi-Ms,1D And 2D NMR (Hsqc,(1)H-(1)H Cosy,Hmbc,Roesy). The Absolute Configuration Of Sugar Unit Was Defined By Acid Hydrolysis And Appropriate Derivatization. Compound 1 Was Rare 5β-H-10β-H-19-Nor-Cardenolide,Which Might Derive From Decarboxylative Derivative Of 19-Cooh Cardenolide. The Inhibitory Effects Of Cardiac Glycosides 1-11 On The Viability Of Nih-H460 Lung Cancer Cells And Their Induction Of Nur77 Expression Were Evaluated And Preliminary Structure-Activity Relationship (Sar) Was Also Discussed.
