生化/生理作用
4-羟基他莫昔芬是他莫昔芬的活性代谢产物。4-羟基他莫昔芬在人肝脏中由细胞色素 P450 2D6 形成，是一种强效选择性雌激素受体拮抗剂。4-羟基他莫昔芬用于刺激 LC3 脂化，并以超氧化物依赖的方式形成自噬囊泡。在原代培养的人肝细胞中，他莫昔芬和 4-羟基他莫昔芬显著诱导细胞色素 P450 3A4（一种主要的药物代谢酶）。4-羟基他莫昔芬经历反 (E-Z) 异构化—这一过程发生在所有常见的实验室溶剂中。
4-羟基他莫昔芬的反式 异构体具有抗雌激素活性，而 顺式 4-羟基他莫昔芬是雌激素受体的关键激动剂。4-羟基他莫昔芬通过激活 乳腺癌细胞中p38 通路促进凋亡。
制备说明
4-羟基他莫昔芬为 13 mM 溶液。推荐工作浓度为 10-100μM。因此，4-羟基他莫昔芬制备液应在细胞培养基中以 1:130-1:1,300 稀释。

Activation of microglia is a prominent pathological feature in tauopathies, including Alzheimer's disease. How microglia activation contributes to tau toxicity remains largely unknown. Here we show that nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) signaling, activated by tau, drives
