Synthesis and biological activities of new di- and trimeric quinoline derivatives

Abstract

The synthesis of non-peptidic helix mimetics based on a trimeric quinoline scaffold is described. The ability of these new compounds, as well as their synthetic dimeric intermediates, to bind to various members of the Bcl-2 protein anti-apoptotic group is also evaluated. The most interesting derivative of this new series (compound A) inhibited Bcl-x(L)/Bak, Bcl-x(L)/Bax and Bcl-x(L)/Bid interactions with IC(50) values around 25 μM.
