While thymopentin has been used for many years in the experimental treatment of Sézary syndrome (SS), a rare and very aggressive lymphoma, its mechanism of action is still not known. Herein we show that this peptide acts as an inhibitor of isolated iNOS and nNOS isoforms, and reduces iNOS protein/mRNA levels and iNOS activity in blood cells obtained from both healthy donors and SS patients. Similar results were obtained with TPN-2, the N(ω)-nitro analogue of the Arg-Lys motif present in thymopentin. Additional investigations are necessary to confirm the role and the relative importance of the two mechanisms of iNOS down-regulation in the therapeutic action of these peptides against SS.
