In this study, we have used the selective A 2A adenosine receptor antagonist KW6002 to investigate the function of A 2A receptors in the Lister hooded rat nucleus accumbens in vitro and in vivo. Radioligand binding studies confirmed a greater than 50-fold selectivity of KW6002 for A 2A receptors compared to A1 receptors.

12-Week, Double-Blind, Placebo-Controlled, Randomized Study of the Efficacy of 40 mg/Day KW-6002 in Parkinson's Disease Patients on Levodopa/Carbidopa.

It has been found to be useful in the treatment of Parkinson's disease. The administration of KW6002 after I-R injury reduced microglia reactivity and inflammatory response and afforded protection to the retina. Moreover, we tested the ability of caffeine, an adenosine receptor antagonist, in mediating protection to the retina in the I-R injury model. Mechanism of Action. Istradefylline, an analog of caffeine, is an adenosine A 2A receptor antagonist, selectively inhibiting the A 2A receptor (human, K i = 12.4 nM), compared to A 1 and A 3 receptors (IC 50 >1000 or 10000 nM), and leading to the restoration hypomotility in patients with Parkinson's disease. Istradefylline, or KW6002, was developed by Kyowa Hakko Kirin in Japan for the treatment of Parkinson's disease as an adjunct to standard therapy.

Istradefylline (KW-6002) Chemical Structure CAS NO. 155270-99-8 Istradefylline (KW-6002) is a selective antagonist at the A2A receptor. It has been found to be useful in the treatment of Parkinson's disease. Objective: Based on new understanding of nondopaminergic pathways involved in Parkinson's disease (PD) pathophysiology, a selective adenosine A(2A) receptor antagonist, istradefylline, shows promise for the treatment of PD. KW6002 (3 mg/kg) was administered by oral gavage 2 h post injury and until the end of experiment (7 days of reperfusion).
