ndesmethyltamoxifen hydrochloride

N-Desmethyltamoxifen hydrochloride 是 Tamoxifen 在人体内主要的三苯氧胺代谢物。它是蛋白激酶 C 抑制剂，也是人体 AML 细胞神经酰胺代谢的有效调节因子，可限制神经酰胺糖基化、水解和鞘氨醇磷酸化。

N-Desmethyltamoxifen, the principal metabolite of tamoxifen in humans, serves as an efficacious modulator of ceramide metabolism within human AML cells by inhibiting ceramide glycosylation, hydrolysis, and sphingosine phosphorylation. Although it demonstrates weak antiestrogenic properties, it acts as a protein kinase C (PKC) inhibitor with a potency ten times greater than that of tamoxifen.
