A new pterocarpan derivative, pruinosanone D (1), a new isoflavonoid, pruinosanone E (2), and a new chalcone, pruinosanone F (3), were isolated from Caragana pruinosa roots, along with four known analogues (4–7), identified as 2,4-dihydroxy-3′-methoxy-4′-ethoxychalcone, 7,4-dihydroxyflavanone, butin and scutellaprostin C, respectively. Their structures were elucidated by detailed analyses of NMR, IR, and MS data. The ability of the isolated compounds to prevent nitric oxide (NO) production by LPS-stimulated RAW 264.7 macrophages was also studied. Compound 1 were among the most potent NO production inhibitor, with IC50 value of 0.62 μM.
Chemical investigation on Caragana pruinosa roots has afforded a new pterocarpan derivative, pruinosanone D (1), a new isoflavonoid, pruinosanone E (2), and a new chalcone, pruinosanone F (3).Figure optionsDownload high-quality image (112 K)Download as PowerPoint slide
