General description
An all-D-amino acid version of the Nur77-derived minimum Bcl-2/Bcl-B/Bfl-1-conformation converting sequence is conjugated with a D-Arg octamer to facilitate its cellular delivery. CD binding studies reveal a 1:1 stoichiometric binding and that Bcl-2 unstructured loop region (aa 29-90) as the main D-NuBCP-9 interacting site with possible additional involvement of the BH4 domain. D-NuBCP-9-induced apoptosis is Bcl-2-dependent (100% vs 0% inhibition, respectively, of MEF vs Bcl-2-/- MEF colonies formation by 15 µM D-NuBCP-9) and requires the presence of either Bak or Bax (0% inhibition of Bax-/-Bak-/- MEF colonies formation). D-NuBCP-9-induced apoptosis in HeLa cultures is also demonstrated to be potentiated by 114% and 78%, respectively, upon vector expression of Bcl-B or Bfl-1. When applied to MDA-MB435-xenografted mice on the 10th & 13th day after cancer cell implant, D-NuBCP-9 (620 µg/mouse) reportedly suppressed tumor growth (by 80% on day 55) by inducing cancer cell apoptosis in vivo.
