LSZ-102 is a potent, orally bioavailable selective estrogen receptor degrader with an IC50 of 0.2 nM.
LSZ-102 is a potent, orally bioavailable selective estrogen receptor degrader with an IC50 of 0.2 nM and currently in Phase I/Ib trials for the treatment of ERα positive breast cancer. LSZ-102 induces significant degradation of ERα after 24 h, when given as a 10 uM solution to MCF-7 cells. Robust inhibition of cell proliferation in MCF-7 cells is observed upon incubation with LSZ-102 with a half inhibitory concentration of 1.7 nM. Results demonstrate that LSZ-102 effectively inhibits the estrogen-induced activation of the ERE-luciferase reporter using charcoal-stripped serum treated with E2 with IC50 of 0.3 nM[1].
Treatment of the mice with LSZ-102 once daily at 20 mg/kg results in significant tumor growth inhibition as compare to the control group treated with vehicle alone, resulting in tumor stasis (mean change in tumor volume of LSZ-102 vs control=%δT/δC of 2.4% on day 48, p<0.05). Dosing of 3 mg/kg solution of LSZ-102 in male Sprague-Dawley rats results in 33% bioavailability and a dose-normalized exposure of 620 nM•h[1].

Kinase experiment: | Growth factors depleted MCF-7 ERE-luc cells are used and seeded (10 000 cells/well) in 96-well plates in CSS medium. After overnight incubation, cells are treated with LSZ-102 in the presence of estradiol (0.1 nM) for 24 h. Cells are then lysed and quantified for luciferase activity using Bright-Glo assay[1]. |
Animal experiment: | Female athymic nude mice are used for tumor xenograft studies. MCF-7 cells are subcutaneously injected (200 μL/animal) in the right axillary mammary fat pad area. Tumor volume and body weights are measured twice weekly. When tumors reach an average volume of ~200 mm3, mice are randomized into different groups. Animals are orally administered vehicle alone or 20 mg/kg LSZ-102 daily or 60 mg/kg tamoxifen 5 days per week[1]. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
