The discovery of small molecule carbamates as potent dual α4β1/α4β7 integrin antagonists
摘要:
The alpha(4)beta(1) and alpha(4)beta(7) integrins are implicated in several inflammatory disease states. Systematic SAR studies of an alpha(4)beta(1)-specific arylsulfonyl-Pro-Tyr lead led to the identification of a new alpha(4)beta(7) binding site, best captured by O-carbamates of Tyr for this structural class. Several compounds showed a 200- to 400-fold improvement in alpha(4)beta(7) binding affinity while maintaining subnanomolar alpha(4)beta(1) activity, for example 21, VCAM-Ig alpha(4)beta(1) IC50 = 0.13 nM. VCAM-Ig alpha(4)beta(7) IC50 = 1.92 nM. (C) 2002 Elsevier Science Ltd. All rights reserved.

(EN) Compounds of formula (I) are antagonists of VLA-4 and/or $g(a)4$g(b)7, and as such are useful in the inhibition or prevention of cell adhesion and cell-adhesion mediated pathologies. These compounds may be formulated into pharmaceutical compositions and are suitable for use in the treatment of asthma, allergies, inflammation, multiple sclerosis, and other inflammatory and autoimmune disorders.(FR) Des composés de formule (I) sont des antagonistes de VLA-4 et/ou de $g(a)4$g(b)7 et sont, en tant que tels, utiles pour inhiber ou empêcher l'adhésion cellulaire et pour lutter contre des pathologies induites par l'adhésion cellulaire. Ces composés peuvent être formulés sous forme de compositions pharmaceutiques et sont adaptés pour être utilisés dans le traitement de l'asthme, des allergies, des inflammations, de la sclérose en plaques et d'autres maladies inflammatoires et auto-immunes.
