Azure C 是一种 tau 寡聚体调节剂与 Aβ42 寡聚化抑制剂,可调控 hsp70 ATPase 活性,进而介导 tau 蛋白的清除。Azure C 可通过促进无毒 tau 聚集体的形成降低毒性 tau 寡聚体水平,拯救神经母细胞瘤细胞免受 tau 寡聚体诱导的毒性作用,还可结合并抑制 Aβ42 寡聚化,但不抑制其纤维化。Azure C 可通过辣根过氧化物酶介导的反应,由亚甲蓝或天青 B 经连续氧化生成,会在 HRP 反应培养基中积累。Azure C 可用于 tau 蛋白病 (包括阿尔茨海默病) 的相关研究。
Azure C acts as a tau oligomer modulator and Aβ42 oligomerization inhibitor. It 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 without suppressing its fibrillization. Azure C is generated via sequential oxidation of methylene blue or Azure B through a horseradish peroxidase-mediated reaction, and accumulates in HRP reaction media. Azure C can be used in studies related to tauopathies, including Alzheimer's disease.
