, (2008/06/13)
The present invention provides a preventive or therapeutic agent of a new type for diabetes mellitus and diabetic complications on the basis of an adenosine A2 receptor antagonistic action. A purine compound represented by the formula (I), its pharmacologically acceptable salt or hydrates thereof has an adenosine A2 receptor antagonistic action and is useful for prevention or therapy of diabetes mellitus and diabetic complications. In addition, adenosine A2 receptor antagonists having different structures from those of the compounds described above, for example KW6002, are also effective for prevention or therapy of diabetes mellitus and diabetic complications. In the formula, W is —CH2CH2—, —CH═CH— or —C≡C—; R1is: (in the formula, X is hydrogen atom, hydroxyl group, a lower alkyl group, a lower alkoxy group, etc.; and R5and R6are the same as or different from each other and each represents hydrogen atom, a lower alkyl group, a cycloalkyl group, etc.) and the like; R2is an amino group, etc. which maybe substituted with a lower alkyl group, etc.; R3is a cycloalkyl group, an optionally substituted aryl group, etc.; and R4is a lower alkyl group etc.

Novel adenosine antagonists, 2-alkynyl-8-aryl-9-methyladenine derivatives, were synthesized as candidate hypoglycemic agents. These analogues were evaluated for inhibitory activity on N-ethylcarboxamidoadenosine (NECA)-induced glucose production in primar
