Synthesis and Biological Evaluation of Novel Carbohydrate-Derived Derivatives of Erlotinib.

Preclinical Research A series of novel carbohydrate-derived Erlotinib derivatives were prepared by the copper-catalyzed cycloaddition reaction of erlotinib with various azido-sugars. The structures of the newly synthesized compounds were characterized and their cytostatic effects evaluated in vitro on human cancer cell lines MDA-MB-231, HEPG-2, A549, and MCF-7 using an MTS assay. The novel erlotinib derivatives had the expected inhibitory effects on MDA-MB-231 and HEPG-2 cell llines. Among the compounds evaluated the carbohydrate-derived compounds 5b, 5d, 6a, and 6c had more potent activities against MDA-MB-231 or HEPG-2 than Erlotinib.
