ChEBI: 4-Hydroxy-N-desmethyltamoxifen is a stilbenoid. | [Biological Activity]
(Z)-Endoxifen (endoxifen) is an active tamoxifen metabolite generated via actions of cytochrome P450 (CYP) enzymes CYP3A4/5 and CYP2D6. Endoxifen is more potent than tamoxifen as a selective estrogen receptor modulator (SERM) both in vitro and in vivo with good pharmacokinetics and oral availability (∼80% MCF-7 tumor growth inhibition with 4-8 mg/kg/day endoxifen or 20 mg/kg/day tamoxifen in mice via p.o.). Endoxifen also exhibits 4-fold higher PKC inhibitory potency than tamoxifen and can overcome tamoxifen resistance due to cytochrome CYP2D6 polymorphism. | [in vivo]
Z-Endoxifen (Z-isomer) (5 mg/kg/day, s.c., gradual drug release every 30 days, pellets replaced every 90 days) effectively prevents breast cancer in the C3(1)-TAg mouse model[3].
Z-Endoxifen (50 mg/kg, p.o., 5 times a week for 4 weeks) shows better antitumor efficacy in the MCF7LR resistant mouse model[4].
Z-Endoxifen (75 mg/kg, p.o., once daily for 4 weeks) shows strong antitumor activity in the MCF7AC1 mouse breast cancer model[4]. Animal Model: | C3(1)-TAg mouse mammary tumorigenesis model, developed by breeding FVB/NJ females with FVB/C3(1)-TAg males (8 weeks), resulting in SV40 T-antigen expression in mammary gland cells and tamoxifen resistance[3] | Dosage: | 5 mg/kg/day | Administration: | Subcutaneously implanted pellets, replaced every 90 days, with each pellet designed to release the drug gradually over 30 days. | Result: | Significantly increased tumor latency and reduced tumor growth. |
Animal Model: | MCF7LR mouse breast cancer model, simulating endocrine-resistant breast cancer, developed by prolonged exposure to Letrozole[4] | Dosage: | Z-Endoxifen: 50 mg/kg (Tamoxifen (HY-13757A): 500 μg/day, Exemestane (HY-13632): 250 μg/day,Everolimus (HY-10218): 2.5 mg/day) | Administration: | Z-Endoxifen: oral gavage (p.o.), the others administered subcutaneously, 5 times a week for 4 weeks | Result: | Significantly reduced tumor volume in the MCF7LR resistant model compared to Tamoxifen and Exemestane. |
