[11C]MeS-IMPY exhibits a higher binding affinity for β-amyloid plaques extracted from Alzheimer's disease (AD) brains or AD brain homogenates than IMPY, with Ki values of 7.93 nM and 8.95 nM, respectively. [11C]MeS-IMPY is a potential radioactive ligand for positron emission tomography (PET) imaging of β-amyloid plaques.

1-1(Z)-Octadecenyl-2-docosahexaenoyl-sn-glycero-3-PE (18:0p 22:6-PE) is a lipid identified in rat brain tissue using mass spectrometry imaging techniques. It exhibits specific structural and distribution properties, allowing the differentiation of isomers of various fatty acid chains through refined methods.

TNIR7-1A is a fused cycloheptatriene-BODIPY derivative that is optimized for near-infrared (NIR) imaging characteristics (Ex Em = 600 774 nm in PBS) and exhibits high affinity and specificity for neurofibrillary tangles (NFT) in vitro. Additionally, TNIR7-1A can effectively penetrate the blood-brain barrier.

CHL2310 is an inhibitor of CYP46A1 with an IC50 of 0.11 nM and a Kd of 0.37 nM. It is capable of crossing the blood-brain barrier. When labeled with radioactive [18F], CHL2310 can serve as a PET imaging agent.

BF-170 is a selective tau fiber-binding agent with an EC50 of 221 nM. It demonstrates excellent blood-brain barrier penetration, reaching a concentration of 9.1% ID g in brain tissue 2 minutes after intravenous injection in mice (with a clearance rate of 0.25% ID g at 30 minutes). BF-170 can serve as a probe for imaging tau protein pathology in Alzheimer's disease (AD). It plays a significant role in early-stage Alzheimer's disease studies and holds promise for imaging research in tau-related neurodegenerative diseases.

Desmethyl-HD-800 is a PET precursor of preparing radiolabel [11C]HD-800, a high affinity brain penetrant PET tracer for imaging microtubules.

SP203 is a radioligand for brain metabotropic glutamate receptor imaging.

The metallo-protein Cu/Zn-superoxide dismutase (SOD1) is a ubiquitous enzyme responsible for scavenging superoxide radicals. Mutations in SOD1, which alter its metal binding capacity and can result in protein misfolding and aggregation, have been linked to familial amyotrophic lateral sclerosis (ALS). Cu-ATSM is an orally bioavailable, blood-brain barrier permeable complex that has traditionally been used in cellular imaging experiments to selectively label hypoxic tissue via its susceptibility to reduction by oxygen-depleted mitochondria. More recently, Cu-ATSM has been reported to improve locomotor function and survival in a transgenic ALS mouse model by delivering copper specifically to cells in the spinal cords of mice producing misfolded SOD1 proteins. Copper chaperone for SOD (CCS) is presumed to utilize the copper from Cu-ATSM to prevent misfolding of the SOD1 protein.

THK-5117 is an arylquinoline derivative with the potential as a PET probe for tau imaging. THK-5117 shows high binding affinity to tau fibrils with a Ki value of 10.5 nM. THK-5117 also shows high binding affinity to tau protein aggregates and tau-rich Alzheimer disease (AD) brain homogenates [1].

THK-5105, an arylquinoline derivative, demonstrates high binding affinity for tau fibrils, protein aggregates, and tau-rich Alzheimer's disease (AD) brain homogenates, indicating its potential as a tau imaging PET (Positron Emission Tomography) probe with the radiolabeled version, 18F-THK-5105 [1].

TRV-7019 is a butyrylcholinesterase-targeting radioligand capable of penetrating the blood-brain barrier (BBB) for brain imaging. It is utilized for diagnosing conditions such as amyloid diseases, multiple sclerosis, brain tumors, or to assess butyrylcholinesterase activity [1].

PBR28, a TSPO modulator, holds potential for preventative research in Pulmonary Arterial Hypertension (PAH) and is instrumental in brain positron emission tomography (PET) imaging studies through its capacity for radioactive labeling to trace the 18 KDa transporter (TSPO) [1].
