Competing Interests

We have the following interests. All authors are employed by the Siena Biotech Medicine Research Centre. The molecules reported in the manuscript (SEN461 and the inactive analogue SEN973) are both covered by patent application (WO/2011/042145), inventors: Massimiliano Salerno and Maurizio Varrone. There are no further patents, products in development or marketed products to declare. This does not alter our adherence to all the PLOS ONE policies on sharing data and materials, as detailed online in the guide for authors.
