  Lignans and Neolignans from Sinocalamus affinis and Their Absolute Configurations

  摘要：

  Twenty-two new lignans and neolignans (1-22), together with 14 known analogues, have been isolated from an ethanolic extract of the stem (with skin removed) of Sinocalamus affinis. Their structures were elucidated by spectroscopic and chemical methods. On the basis of systematic NMR and circular dichroism (CD) data analysis, the validity of J(7,8) and Delta delta(C8-C7) values to distinguish threo and egthro aryl glycerol units in different neolignans and the CD data [particularly the Rh-2(OCOCF3)(4)-induced CD data (the E band)] to determine the absolute configurations at C-8 (C-7) of the aryl glycerol units are discussed. At a concentration of 10 mu M, compounds 20 and 22 inhibited NO production in mouse peritoneal macrophages 84.2 +/- 5.9% and 71.7 +/- 1.0%, respectively. Compounds 19, 20, and 22 showed activity against serum deprivation induced PC12 cell damage by increasing the cell viability from 80.7 +/- 2.8% to 91.6 +/- 6.4%, 107.2 +/- 8.0%, and 97.6 +/- 8.5%, respectively.
