The present disclosure relates to a compound of formula (I)
wherein:
A is an optionally substituted monocyclic or polycyclic aryl or heteroaryl group; B is an optionally substituted monocyclic nitrogen-containing heteroaryl group; and either a) R
1
and R
2
are chosen from a hydrogen atom and specified substituents, or b) R
2
, R
1
and the —NH— group to which R
1
is attached, form a moiety chosen from the moiety of formulae (IIa) and (IIb):
or a pharmaceutically acceptable salt thereof, or a N-oxide thereof. The present disclosure also relates to a method for treating a subject afflicted with a pathological condition or disease susceptible to amelioration by antagonism of the A
2B
adenosine receptor.

[EN] The present invention provides a compound of formula (I) wherein: A represents an optionally substituted monocyclic or polycyclic aryl or heteroaryl group B represents an optionally substituted monocyclic nitrogen-containing heteroaryl group ; and either a) R1 and R2 represent hydrogen or specified substituents, or b) R2, R1 and the -NH- group to which R1 is attached, form a moiety selected from the moiety of formulae (IIa) and (IIb): (IIa) These compounds are useful as antagonists of the A2B receptor, for instance in the treatment of asthma. [FR] La présente invention propose un composé de formule (I) dans laquelle : A représente un groupe aryle ou hétéroaryle monocyclique ou polycyclique facultativement substitué, B représente un groupe hétéroaryle contenant de l'azote facultativement substitué ; et a) R1 et R² représentent un hydrogène ou des substituants spécifiés, ou b) R², R1 et le groupe -NH- auquel R1 est lié, forment un groupe choisi parmi les groupes de formule (IIa) et (IIb) : (IIa) Ces composés sont utiles en tant qu'antagonistes du récepteur A2B, par exemple dans le traitement de l'asthme.
