N-tert-butyl-α-Phenylnitrone((Z)-N-benzylidene-2-Methylpropan-2-aMine oxide) possesses potent reactive oxygen species scavenging, anti-inflammatory, neuroprotective, anti-aging, and anti-diabetic activities, and can penetrate the blood-brain barrier.

α-Thujone is an inhibitor of ACh with an IC50 value of 24.7μM.

Spermine (N3BBB), a click chemistry reagent with an azide group, facilitates diverse biochemical studies [1].

Debio 0932 (CUDC-305) is a heat shock protein 90 (Hsp90) inhibitor that targets the n-terminal atp-binding pocket to promote apoptosis, and has the advantage of being orally available and able to cross the blood-brain barrier (BBB) for the treatment of cancers such as non-small-cell lung cancer (NSCLC) and neuroblastoma.

Repinotan (BAY x 3702 free base) is an orally active, selective 5-HT1A receptor agonist that crosses the blood-brain barrier (BBB), exhibits neuroprotective activity, counteracts morphine-induced depression of ventilation in anesthetized rats, and may be used in studies of acute ischemic stroke and traumatic brain injury.

Rivastigmine (Exelon) is a Cholinesterase Inhibitor, used for therapy of Alzheimer disease.

Baclofen (Lioresal) is a synthetic chlorophenyl-butanoic acid derivative used to treat spasms due to spinal cord damage and multiple sclerosis, muscle-relaxing Baclofen acts as a gamma-aminobutyric acid (GABA) agonist specific for GABA-B receptors. It acts at spinal and supraspinal sites, reducing excitatory transmission.

Rivastigmine tartrate (SDZ-ENA 713) is a carbamate-derived reversible CHOLINESTERASE INHIBITOR that is selective for the CENTRAL NERVOUS SYSTEM and is used for the treatment of DEMENTIA in ALZHEIMER DISEASE and PARKINSON DISEASE.

J-147 is an experimental drug with reported effects against both Alzheimer's disease and ageing in mouse models of accelerated aging. It is a curcumin derivative and a potent neurogenic and neuroprotective drug candidate initially developed for the treatment of neurodegenerative conditions associated with aging that impacts many pathways implicated in the pathogenesis of diabetic neuropathy.

4-Hydroxyantipyrine is formed during oxidative deamination of aminopyrine.

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.

GNE-0723 is a selective positive allosteric modulator of the NMDA receptor, with an EC50 of 21 nM for GluN2A. It can cross the blood-brain barrier (BBB) and improve outcomes in Dravet syndrome (DS) and Alzheimer's disease (AD).

Carbetocin is an obstetric drug used to control postpartum hemorrhage and bleeding after giving birth.

Nitrobenzylthioinosine (NBMPR) is an inhibitor of ENT1 transporter that binds to ENT1 transporter with high affinity.

AS057278 (3-Methylpyrazole-5-carboxylic acid) is an D-amino acid oxidase (DAAO) inhibitor.

A 1070722 is a potent and selective GSK-3 inhibitor, exhibiting high affinity for both GSK-3α (Ki = 0.6 nM) and GSK-3β (Ki = 0.6 nM). It can penetrate the blood-brain barrier (BBB) and accumulate in brain regions, indicating potential use as a PET radiotracer for quantifying GSK-3 in the brain.

BuChE-IN-TM-10 (TM-10) is a potent inhibitor of butyrylcholinesterase (BuChE) with an IC50 of 8.9 nM. It effectively inhibits and disaggregates self-induced Aβ aggregation, exhibits significant antioxidant activity, and demonstrates substantial penetration through the blood-brain barrier (BBB), holding promise as a potential treatment for Alzheimer's disease.

GSK-3β inhibitor 2 (5-Thiazolecarboxamide,2-[2-[(cyclopropylcarbonyl)amino]-4-pyridinyl]-4-methoxy-) is a BBB-crossing and selective inhibitor of GSK-3β (IC50 = 1.1 nM). GSK-3β inhibitor 2 can be used in studies about Alzheimer's disease.
