生物活性

Istradefylline is a very potent, selective and orally active adenosine A2A receptor antagonist with K_i of 2.2 nM in experimental models of Parkinson's disease.

体外研究

Istradefylline has 70-fold greater affinity for the A2AR than the A1 receptor with K_i of 2.2 nM versus 150 nM. Istradefylline causes concentration-dependent abolition of bFGF induction of astrogliosis in primary rat striatal astrocytes. Istradefylline binds to A1 receptor, A2A receptor, and A3 receptor in human with K_is of >287 nM, 9.12 nM, and >681 nM, respectively, 50.9 nM and 1.57 nM for A1 receptor and A2A receptor in rat, 105.02 nM and 1.87 nM for A1 receptor and A2A receptor in mouse, respectively.

体内研究

Istradefylline (3.3 mg/kg, i.p.) treatment before a single dose of MPTP attenuates the partial dopamine and DOPAC depletions measured in striata 1 week later. Istradefylline reverses CGS21680-induced and reserpine-induced catalepsy with an ED₅₀ of 0.05 mg/kg and 0.26 mg/kg, respectively. Istradefylline is over 10 times as potent in these models compared to other adenosine antagonists and dopamine agonist drugs. Istradefylline combined with L-dopa cuases potent effects on haloperidol-induced and reserpine-induced catalepsy. Istradefylline (10 mg/kg, p.o.) results an increase in locomotor activity to approximately twice that of control and improves motor disability in MPTP-treated common marmosets. Istradefylline (10 mg/kg, p.o.) in combination with SKF80723, quinpirole, or L-DOPA produces a significant additive effect on locomotor activity and improvement of motor disability but not dysK_inesia.
