Aryltetralols from Holostylis reniformis and syntheses of lignan analogous
摘要:
Two new lignans, an aryltetralol and its methyl ether analogous, were isolated from Holostylis reniformis (Aristolochiaceae) together with futokadsurin C and (-)-8'-epi-aristoligone. The latter was also obtained as an enantiomeric mixture by synthesis and was transformed into aryltetralols and aryltetralenes that were subjected to chiral-HPLC separations. The compound structures were determined by spectroscopic methods. Several of these lignans had their antiplasmodial activity (against Plasmodium falciparum, W2 clone, anti-HRPII) and toxicity to mammalian kidney cells (MDL50) evaluated. (-)-Cyclogalgravin and (-)-aristoligol exhibited activity (IC50 similar to 10.8 and 8.4 mu M, respectively), the latter exhibited lower toxicity. (C) 2015 Phytochemical Society of Europe.
