Azure C
Based on 1 Customer Validation
Azure C (Monomethylthionine) acts as a tau oligomer inhibitor and Aβ42 oligomerization inhibitor. Azure C regulates hsp70 ATPase activity, thereby mediating the clearance of tau protein. Azure C reduces the levels of toxic tau oligomers by promoting the formation of non-toxic tau aggregates, rescues neuroblastoma cells from tau oligomer-induced toxicity, and binds to and inhibits Aβ42 oligomerization. Azure C is generated via continuous oxidation of methylene blue or azure B through a horseradish peroxidase-mediated reaction. Azure C can be used in research related to tauopathies, including Alzheimer's disease.

In Vitro
Azure C (0.05-10 μM; 16 h) reduces levels of purified preformed tau oligomers in a concentration-dependent manner, with a significant reduction observed at 5 μM[1].
Azure C (2.5-10 μM; 16 h) significantly reduces levels of purified preformed tau oligomers, without altering total tau levels[1].
Azure C (5 μM; 16 h preincubation with preformed tau oligomers) reduces the oligomers' toxicity to SH-SY5Y human neuroblastoma cells[1].
Azure C (5 μM; 16 h) reduces levels of toxic tau oligomers from crude tau oligomeric preparations and decreases their hydrophobicity, without disassembling oligomers into monomeric tau[1].

Protocol for Pharmacokinetic Study
Pharmacokinetic studies quantify how an organism handles a drug over time through absorption, distribution, metabolism, and excretion, and the core experimental readout is the concentration-time profile of parent drug and, when relevant, metabolites in biological matrices such as plasma, whole blood, urine, bile, or tissue. Pharmacokinetic analysis links dose, route, exposure, clearance, half-life, distribution, bioavailability, and systemic exposure to drug efficacy and toxicity hypotheses rather than measuring a signaling pathway directly. The literature links pharmacokinetics to drug-development phenotypes by showing that drug metabolism and pharmacokinetics influence compound progression, exposure-response interpretation, safety margins, dosing strategy, and failure risk during discovery and development. DMPK science contributes to compound optimization by integrating physicochemical properties, in vitro metabolism, transporter behavior, in vivo exposure, and pharmacodynamic contex

Alzheimer’s Disease Modeling
Alzheimer’s Disease (AD) is a neurodegenerative disorder characterized by a progressive decline in cognitive functions and loss of specific types of neurons and synapses. Alzheimer's symptoms can be simulated in mice by injecting drugs (such as Aβ) or genetically modified.
