Structure-activity relationships of 8-styrylxanthines for in vivo adenosine A(2A) antagonism were explored. Diethyl substitution both at the 1- and S-position was found to dramatically potentiate the anti-cataleptic activity.

Agents for the treatment of Parkinson''s disease contain, as an active ingredient, a xanthine derivative or a pharmaceutically acceptable salt thereof. The xanthine derivative is represented by the formula: STR1 in which R 1, R 2 are R 3 are independently hydrogen, lower alkyl, lower alkenyl, or lower alkynyl; and R 4 represents cycloalkyl, --(CH 2) n --R 5 (in which R 5 represents substituted or unsubstituted aryl or a substituted or unsubstituted heterocyclic group; and n is an integer of 0 to 4), or STR2 in which Y 1 and Y 2 represent independently hydrogen, halogen, or lower alkyl; and Z represents substituted or unsubstituted aryl, STR3 in which R 6 represents hydrogen, hydroxy, lower alkyl, lower alkoxy, halogen, nitro, or amino; and m represents an integer of 1 to 4, or a substituted or unsubstituted heterocyclic group; and X 1 and X 2 represent independently O or S.

The present invention relates to an antidepressant containing as an active ingredient a xanthine derivative or a pharmaceutically acceptable salt thereof, the xanthine derivative being represented by Formula (I) : STR1 in which R1, R2, and R3 represent independently hydrogen, lower alkyl, lower alkenyl; R4 represents cycloalkyl, --(CH2)n --R5 (in which R5 represents substituted or unsubstituted aryl or a substituted or unsubstituted heterocyclic group; and n is an integer of 0 to 4), or STR2 (in which Y1 and Y2 represent independently hydrogen, halogen or lower alkyl; and Z represents substituted or unsubstituted aryl, STR3 (in which R6 represents hydrogen, hydroxy, lower alkyl, lower alkoxy, halogen, nitro, or amino; and m represents an integer of 1 to 3), or a substituted or unsubstituted heterocyclic group); and X1 and X2 represent independently O or S.
