journal contribution
posted on 2017-02-08, 00:00 authored by Makanjuola Ogunsina, Pranati Samadder, Temilolu Idowu, Gilbert Arthur, Frank SchweizerWe describe metabolically inert l-glucosamine-based glycosylated
antitumor ether lipids (L-GAELs) that retain the cytotoxic effects
of the D-GAELs including the ability to kill BT-474 breast cancer
stem cells (CSCs). When compared to adriamycin, cisplatin, and the
anti-CSC agent salinomycin, L-GAELs display superior activity to kill
cancer stem cells (CSCs). Mode of action studies indicate that L-GAELs
like the D-GAELs kill cells via an apoptosis-independent mechanism
that was not due to membranolytic effects.
