Abstract:
Compounds of formula (I) are A 2B  receptor antagonists: Wherein R 1  is optionally substituted aryl or an optionally substituted 5- or 6-membered heteroaryl ring; R 2  and R 3  are independently selected from hydrogen, C 1 -C 6  alkyl, C 3 -C 8  cycloalkyl, C 3 -C 8  cycloalkyl-(C 1 -C 6 )-alkyl, aryl-(C 1 -C 6 )-alkyl optionally substituted in the ring part thereof, a 5- or 6-membered monocyclic heterocyclic group optionally linked via a C 1 -C 6  alkylene chain and optionally substituted in the ring part thereof, benzimidazol-2-yl-methyl, pyrid-3-yl-carbonyl, or (1-methyl-piperidin-4-yl)-carbonyl-methyl; or R 2  and R 3  taken together with the nitrogen atom to which they are attached form an optionally substituted 5- or 6-membered ring; R 4  is C 1 -C 3  alkyl, C 2 -C 3  alkenyl, —N(—R 5 )—R 6 , or optionally substituted heteroarylmethylamino; and R 5  and R 6  are independently selected from hydrogen or C 1 -C 3  alkyl; or R 5  and R 6  taken together with the nitrogen atom to which they are attached form an optionally substituted 4- to 6-membered saturated ring.

Claim (Index 1):
A compound of formula (I) or a pharmaceutically acceptable salt, hydrate or solvate thereof: wherein R 1  is optionally substituted aryl or an optionally substituted 5- or 6-membered heteroaryl ring; R 2  and R 3  are independently selected from hydrogen, C 1 -C 6  alkyl, C 3 -C 8  cycloalkyl, C 3 -C 8  cycloalkyl-(C 1 -C 6 )-alkyl, aryl-(C 1 -C 6 )-alkyl optionally substituted in the ring part thereof, a 5- or 6-membered monocyclic heterocyclic group optionally linked via a C 1 -C 6  alkylene chain and optionally substituted in the ring part thereof, benzimidazol-2-yl-methyl, pyrid-3-yl-carbonyl, or (1-methyl-piperidin-4-yl)-carbonyl-methyl; or R 2  and R 3  taken together with the nitrogen atom to which they are attached form an optionally substituted 5- or 6-membered ring; R 4  is C 1 -C 3  alkyl, C 2 -C 3  alkenyl, \u2014N(\u2014R 5 )\u2014R 6 , or optionally substituted heteroarylmethylamino; and R 5  and R 6  are independently selected from hydrogen or C 1 -C 3  alkyl; or R 5  and R 6  taken together with the nitrogen atom to which they are attached form an optionally substituted 4- to 6-membered saturated ring.
