The invention relates to the chitosan polymer derivatives of formula I:
and pharmaceutically acceptable salts and esters thereof, wherein Y, X

, X
4
, R1, R2, and n are defined in the detailed description and claims. The chitosan polymer derivatives of formula I bind to or associate with alpha-4-beta-1 (α4β1) and alpha-V-beta-3 (αVβ3) integrin dimers and can be used in delivery formulations to deliver drugs, nucleic acids, or other therapeutic compounds to tissues or cells expressing such integrins.
Compounds of the formula:
are disclosed which have activity as inhibitors of binding between VCAM-1 and cells expressing VLA-4. Such compounds are useful for treating diseases whose symptoms and/or damage are related to the binding of VCAM-1 to cells expressing VLA-4.

(EN) The present invention relates to small molecules according to formula (I), which are potent inhibitors of $g(a)4$g(b)1 mediated adhesion to either VCAM or CS-1 and which can be used for treating or preventing $g(a)4$g(b)1 adhesion mediated conditions in a mammal such as a human.(FR) La présente invention concerne de petites molécules de la formule (I) qui sont des inhibiteurs puissants de l'adhérence induite par $g(a)4$g(b)1 soit à une molécule d'adhérence cellulaire vasculaire (VCAM) soit à un segment de raccord (CS-1). Ces petites molécules peuvent être utilisées pour traiter ou empêcher des troubles associés à l'adhérence induite par $g(a)4$g(b)1 chez un mammifère tel qu'un être humain.
