Tau Protein Ligand

(E/Z)-Florzolotau ((E/Z)-APN1607) is a mixed configuration or unspecified configuration of Florzolotau (HY-137557). Florzolotau (APN1607) is a positron emission tomography (PET) ligand that can be used for the detection of Alzheimer's disease (AD) and other tau proteinopathies. Its binding sites are located in the β-sheet of paired helical filaments (PHFs) and straight filaments (SFs) of tau protein, as well as in the C-shaped cavity of SFs. In addition, APN-1607 binds to intraneuronal inclusions in Alzheimer's disease (AD), primary age-related tauopathy (PART) and posterior cortical atrophy (PCA). Florzolotau shows promise for PET imaging studies of neurological disorders, particularly tau proteinopathies.

T808 is a selective tau protein-targeting ligand. T808 can be used to synthesize [¹⁸F]-T808, a highly selective tau protein positron emission tomography (PET) tracer. T808 can also be used to synthesize [³H]-T808, a marker for in vitro experiments. T808 can be used for the research of alzheimer’s disease.

Aberrant tau ligand 1 is a tau protein ligand. Aberrant tau ligand 1 engages tau and CRBN to trigger proteasomal degradation. Aberrant tau ligand 1 can be used for synthesis PROTACs, such as QC-01–175 (HY-134850).

Tau ligand-1 (Compound 75) is a ligand for aggregated tau protein that can penetrate the blood-brain barrier. In tissues from patients with Alzheimer's disease, progressive supranuclear palsy, corticobasal degeneration, and Pick's disease, Tau ligand-1 exhibits high affinity for aggregated tau protein, with equilibrium dissociation constant (K_D) values ranging from 1 to 3.8 nM. Tau ligand-1 can serve as a potential positron emission tomography (PET) tracer and holds promise for application in positron emission tomography imaging studies of tau-related diseases in the central nervous system.

Aberrant tau ligand 2 (Compound 4-12) is the ligand for tau protein and can be used as target protein ligand for synthesis of PROTAC degrader C004019 (HY-138669).

BF-170 is a selective tau fibril binding agent with an EC₅₀ of 221 nM. It exhibits good blood-brain barrier permeability, and after intravenous injection in mice, the concentration in brain tissue reaches 9.1% ID/g within 2 minutes (with a brain clearance rate of 0.25% ID/g after 30 minutes). BF-170 can be used as a probe for tau protein pathology imaging in Alzheimer's disease (AD). It plays an important role in early-stage AD research and holds potential for imaging studies of tau-related neurodegenerative diseases.

JNJ-64326067 is an aggregated tau-binding agent with blood-brain barrier permeability, with a K_i of 2.4 nM. JNJ-64326067 selectively binds to aggregated tau protein but does not bind to aggregated β-amyloid protein, and shows no significant off-target binding to the tested receptors, ion channels, transporters, kinases or monoamine oxidases. JNJ-64326067 is applicable to the research of Alzheimer's disease.

Tau ligand-2 is a tau aggregate ligand with a K_i value of 0.99 nM. Radiolabeled (¹⁸F) Tau ligand-2 serves as a PET tracer. Tau ligand-2 is applicable to research related to Alzheimer's disease.
