Description: | N-Desmethyltamoxifen is the major metabolite of tamoxifen in humans. N-Desmethyltamoxifen, a poor antiestrogen, is a ten-fold more potent protein kinase C (PKC) inhibitor than Tamoxifen. N-Desmethyltamoxifen is also a potent regulator of ceramide metabolism in human AML cells, limiting ceramide glycosylation, hydrolysis, and sphingosine phosphorylation. |
Target: | PKC |
In Vitro: | N-desmethyltamoxifen (20-500 ng/ml; 48 hours) has a profound inhibitory effect upon all seven glioma lines (T98G, U87, U138, U373, ALW, AUK, CAS cells)[1]. N-desmethyltamoxifen (1.5-10 μM; 114 hours) inhibits growth of MCF 7 human mammary carcinoma cells[2]. N-desmethyltamoxifen, resulting from the CYP3A4/5-mediated catalysis of tamoxifen, is the major primary quantitative metabolite of tamoxifen[3]. Cell Viability Assay[2] Cell Line: MCF 7 human mammary carcinoma cells Concentration: 1.5, 2.5, 5, 7.5, 10 μM Incubation Time: 114 hours Result: Inhibits growth of MCF 7 human mammary carcinoma cells |
