Aziridines from alkenyl-β-D-galactopyranoside derivatives: Stereoselective synthesis and in vitro selective anticancer activity
摘要:
A series of new aziridines beta-D-galactopyranoside derivatives were synthesized from alkenyl beta-D-galactopyranosides employing Sharpless conditions. The structures of the compounds were established by H-1 NMR, C-13 NMR, MS, HRMS and elemental analysis. The stereoselectivity of the reaction and the structural requirements of the alkenyl precursor for improving diastereoisomeric excesses of the direct aziridination reaction were also studied.The new compounds were subjected to a preliminary screening for cytotoxic activity against human lung cancer cells vs. human non-malignant lung cells. Terminal aziridine derivatives showed activity and, most notably, selectivity. One of the most active and selective compounds was also evaluated against breast cancer cells, melanoma cells, and non-malignant cells from the same origin. Its cytotoxic activity was similar to that of the positive controls, displaying a highly selective cytotoxic activity against both types of cancer cells. (C) 2013 Elsevier Masson SAS.
