Towards boron neutron capture therapy: the formulation and preliminary in vitro evaluation of liposomal vehicles for the therapeutic delivery of the dequalinium salt of bis-nido-carborane

Bioorg Med Chem Lett. 2013 Nov 15;23(22):6161-6. doi: 10.1016/j.bmcl.2013.09.003. Epub 2013 Sep 10.

Abstract

Liposomes of phosphatidylcholine or of dimyristoylphosphatidylcholine that incorporate bis-nido-carborane dequalinium salt are stable in physiologically relevant media and have in vitro toxicity profiles that appear to be compatible with potential therapeutic applications. These features render the structures suitable candidate boron-delivery vehicles for evaluation in the boron neutron capture therapy of cancer.

Keywords: Bis-nido-carborane; Boron neutron capture therapy; Liposomes; Stability; Toxicity.
