一般說明

4-羟基他莫昔芬(4-OHT)是第一代选择性雌激素受体调节剂(SERM),在乳腺癌细胞中起拮抗剂作用,但在子宫和骨骼中可表现出雌激素样活性。它是他莫昔芬(TAM)前药的活性代谢产物,发挥雌激素受体拮抗剂作用。4-OHT结合雌激素受体来抑制雌二醇诱导的细胞增殖,但不引起细胞毒性。4-OHT是抗雌激素药物他莫昔芬的代谢产物,与他莫昔芬和它的其他代谢物相比,4-OHT结合雌激素受体的亲和性更高,对正常人乳腺细胞和乳腺癌细胞系培养物的增殖抑制效力高50-100倍。

在不添加雌激素、通过胰岛素或表皮生长因子刺激细胞增殖的培养条件下,4-OHT可有效抑制细胞生长。4-OHT可抑制细胞膜内的脂质过氧化,具有过氧自由基清除活性。

應用

4-羟基它莫西芬已用于:
  • 诱导小肠类器官的重组。
  • 研究其对人外周血单个核细胞(PMNC)形成造血细胞集落的能力的影响。
  • 诱导成神经细胞瘤细胞系中MYCN 的过度表达,以确定MYCN表达的升高如何影响成神经细胞瘤细胞对BIRC5/生存素抑制剂YM155诱导细胞凋亡的敏感性。

生化/生理作用

化疗药物他莫昔芬的代谢物,表现出比母体药物更有效的雌激素激动剂/拮抗剂活性。也具有脂质过氧化的膜内抑制剂的活性。

Phosphatidylinositol 3-kinase (PI3K), protein kinase B (AKT1), and c-myc have well-established roles in promoting the maintenance of murine embryonic stem cells (mESCs). In contrast, the activity of glycogen synthase kinase 3beta (GSK3beta), a negatively regulated target of AKT1 signaling, antagonizes
