Eltanexor Z-isomer exhibits different inhibitory effects on Z138, MM15, 3T3 cell lines, with IC50s of 100 nM-50 μM, < 100 nM, > 30 μM, respectively.Eltanexor Z-isomer is the less active isomer of KPT-8602. KPT-8602 is a potent CRM1 inhibitor.
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.
