Istradefylline (KW-6002)(Ki of 2.2 nM) is a selective adenosine A2A receptor (A2AR) antagonist, which is under development in Phase 3 trails. It has been used in trials studying the treatment and basic science of Drug Abuse, Sleep Disorder, Hepatic Impairment, Parkinson's Disease, and Restless Legs Syndrome, among others.

Seridopidine (ACR343) is a modulator of dopaminergic activity that is used as an oral therapy for schizophrenia, Parkinson's disease, and Tourette's syndrome.

AMC-01 has potential antiviral activity and induces dose- and time-dependent inactivation of eIF2-α via phosphorylation of serine residue 51. AMC-01 can be used to study atherosclerosis and Parkinson's syndrome.

BDBM50597431 is an NMDA receptor modulator that may have can be used to study Alzheimer's disease and Parkinson's syndrome.

CBiPES hydrochloride (CBiPES HCl) is a potent orthosteric modulator of the mGlu2 receptor with an EC50 value of 92.8 nM.CBiPES hydrochloride blocks the action of WT and mGlu(3) receptors.CBiPES hydrochloride can be used to study neurological disorders like epilepsy and Parkinson's syndrome. CBiPES hydrochloride can be used to study neurological disorders like epilepsy and Parkinson's syndrome.

(Rac)-GSK 372475 may be investigated for the treatment of Parkinson's syndrome, depression and obesity.

DCAT Maleate is an inhibitor of N-methyl transferases (NMT). DCAT Maleate methylate non-methylated pre-neurotoxins to prevent the formation of Parkinson's syndrome neurotoxins.

Pramipexole (SND 919) is a selective dopamine receptor agonist used in the therapy of Parkinson disease. Pramipexole therapy is associated with a low rate of transient serum enzyme elevations during treatment but has not been implicated in cases of clinically apparent acute liver injury.

Safinamide (FCE-26743) is a reversible and selective monoamine oxidase B (IC50 0.098μM) inhibitor, reducing the degradation of dopamine, and a glutamate release inhibitor (IC50 8μM). It also inhibits dopamine reuptake. Safinamide also blocks sodium and calcium channels. Potential additional uses of Safinamide might be Parkinson's disease, restless leg syndrome and epilepsy.

Orphenadrine hydrochloride (Mephenamin) is a muscarinic antagonist used to treat drug-induced parkinsonism and to relieve pain from muscle spasm.

Orphenadrine Citrate (Flexon) is a skeletal muscle relaxant, it acts in the central nervous system to produce its muscle relaxant effects.

NNZ 2591, a synthetic analogue of cyclic glycine-proline (cGP), exhibits oral activity and the ability to cross the blood-brain barrier. This compound demonstrates neuroprotective properties following ischemic brain injury and improves motor function in a rat model of Parkinson's disease. NNZ 2591 holds research potential for ischemic brain injury and Angelman syndrome [1] [2] [3].

Pramipexole dihydrochloride hydrate (Mirapex) is the hydrochloride salt of pramipexole, a benzothiazole derivative. As a nonergot dopamine agonist, pramipexole binds to D2 and D3 dopamine receptors in the striatum and substantia nigra of the brain.
