Description
8-(3-Chlorostyryl)caffeine (CSC) is an adenosine A
2 receptor antagonist (K
i = 54 nM). It is selective for adenosine A
2 over A
1 receptors (K
i = 28 μM). CSC reverses locomotor depression induced by the adenosine A
2A agonist APEC in mice (ED
50 = 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 A
2 receptor levels induced by L-DOPA in a rat model of Parkinson’s disease induced by 6-OHDA . It also inhibits monoamine oxidase B (MAO-B; K
i = 100 nM) and reduces MAO-B activity in brain mitochondrial preparations from wild-type and
A2A-/- mice.
Definition
ChEBI: 8-(3-chlorostyryl)caffeine is caffeine substituted at its 8-position by an (E)-3-chlorostyryl group. It has a role as an adenosine A2A receptor antagonist and an EC 1.4.3.4 (monoamine oxidase) inhibitor. It is a trimethylxanthine and a member of monochlorobenzenes. It is functionally related to a caffeine.
