Syntheses and Cytotoxicities of Four Stereoisomers of Muricatacin from d -Glucose
摘要:
Four stereoisomers of muricatacin 1a-d were prepared by the reaction of corresponding aldehydes 4a-d, which in turn were prepared from D-glucose, with the anion of triethylphosphonoacetate followed by reduction and cyclization under acidic conditions. Cytotoxicities of four stereoisomers were tested against in vitro A-549 cell line as well as MCF-7 cell line. Stereochemistry at C-4 and C-5 position of muricatacin did not affect the cytotoxicities significantly. (C) 1998 Elsevier Science Ltd. All rights reserved.
