Abstract: There is provided a complex of a 6,7-dihydroxy coumarin phosphonium amphiphile together with a negatively charged agent. The complex self-assembles into a nanoparticle or non-viral vector for facilitating delivery of the negatively charged agent. The negatively charged agent may be a therapeutic agent or a diagnostic agent. Thus, the present invention provides a method of delivery of such negatively charged agents to a target cell, and in particular facilitates delivery of a therapeutic or diagnostic agent across the plasma membrane, as well as a method of treatment or diagnosis via delivery of the therapeutic or diagnostic agent. The 6,7-dihydroxy coumarin phosphonium amphiphile can be Mito-Esc and the negatively charged agent can be a nucleic acid such as siRNA. Additionally, the 6,7-dihydroxy coumarin phosphonium amphiphile is believed to be effective in the treatment of cancer.
