Competing Interests

The authors have read the journal's policy and have the following conflicts: C. Pisano is an employee of Sigma-Tau, and the authors declare that they have a patent as follows: Title: Biphenyl and naphthyl-phenyl hydroxamic acid derivates; Inventors: Claudio Pisano, Giuseppe Giannini, Loredana Vesci, Franco Zunino, Sabrina Dallavalle, Lucio Merlini, Sergio Penco; United States Patent Application Publication: Pub. No. US 2008/0319082 A1; Pub. Date: Dec. 25, 2008. This does not alter the authors' adherence to all the PLoS ONE policies on sharing data and materials. There are no other competing interests to declare.
