Title
(EN) BLT2 AGONISTS FOR THE TREATMENT OF PAIN
(FR) AGONISTES DE BLT2 POUR LE TRAITEMENT DE LA DOULEUR
Abstract
(EN) The present invention pertains to novel analgesics useful for treating pain. BLT2 agonists were found to desensitize TRPV1 mediated signalling in sensory neurons. Thus the invention provides BLT2 agonists as novel pain therapeutics. Additional aspects of the invention pertain to combinations of BLT2 agonists with BLT1 antagonists for treating pain in subjects. Pharmaceutical compositions and kits comprising the new analgesics of the invention are furthermore provided.
(FR) La présente invention concerne de nouveaux analgésiques utiles pour le traitement de la douleur. On a découvert que les agonistes de BLT2 désensibilisent la signalisation médiée par TRPV1 dans des neurones sensoriels. Ainsi, l'invention concerne des agonistes de BLT2 utilisés en tant que nouveaux agents thérapeutiques de la douleur. Des aspects supplémentaires de l'invention concernent des combinaisons d'agonistes de BLT2 avec des antagonistes BLT1 pour le traitement de la douleur chez des sujets. L'invention porte en outre sur des compositions pharmaceutiques et sur des kits comprenant les nouveaux analgésiques de l'invention.
