Abstract
(EN) The present invention provides a method of modulating leukocytes activation (e.g., adhesion and/or transmigration and/or cytokine response) and a method of modulating thrombocyte clearance comprising administering to a subject in need thereof a specific inhibitor of neuraminidase 1 (neu1); neuraminidase 3 (neu3) or neuraminidase 4 (neu4); or a bispecific inhibitor of neu1, neu3 or neu4 of formula (I): (I) Also provided are pharmaceutical compositions comprising the inhibitor compound of formula (1), and uses thereof for modulating leukocytes activation or modulating thrombocyte clearance.
(FR) La présente invention concerne une méthode de modulation de l'activation des leucocytes (par exemple l'adhésion et/ou la transmigration et/ou la réponse des cytokines) et une méthode de modulation de la clairance des thrombocytes comprenant l'administration à un sujet qui en a besoin d'un inhibiteur spécifique de la neuraminidase 1 (neu1); la neuraminidase 3 (neu3) ou la neuraminidase 4 (neu4); ou un inhibiteur bispécifique de neu1, neu3 ou neu4 de formule I : (I). L'invention concerne également des compositions pharmaceutiques comprenant le composé inhibiteur de formule 1, et leurs utilisations pour moduler l'activation des leucocytes ou moduler la clairance des thrombocytes.
