Notes: 8-(3-Chlorostyryl)caffeine (CSC) is an adenosine A2 receptor antagonist (Ki = 54 nM).{53268} It is selective for adenosine A2 over A1 receptors (Ki = 28 µM). CSC reverses locomotor depression induced by the adenosine A2A agonist APEC in mice (ED50 = 16 µg/kg, i.p.). It increases locomotion in mice when administered at a dose of 5 mg/kg. CSC (5 mg/kg) reverses the shortening of the rotational motor response and increases in striatal adenosine A2 receptor levels induced by L-DOPA (Item No. 13248) in a rat model of Parkinson’s disease induced by 6-OHDA (Item No. 25330).{53269} It also inhibits monoamine oxidase B (MAO-B; Ki = 100 nM) and reduces MAO-B activity in brain mitochondrial preparations from wild-type and A2A-/- mice.{53270}
