生物活性

SAR439859 (compound 43d) is an orally active, nonsteroidal and selective estrogen receptor degrader (SERD). SAR439859 is a potent ER antagonist and has ER degrading activity with an EC50 of 0.2 nM for ERα degradation. SAR439859 demonstrates robust antitumor efficacy and limited cross-resistance in ER breast cancer.

体外研究

SAR439859 (compound 43d) induces strong in vivo antitumor activity against a variety of BC cell lines and patient-derived xenografts, including models that harbor ERα mutations.

体内研究

SAR439859 (compound 43d; orally; 2.5-25 mg/kg; twice daily for 30 days) exhibits substantial tumor-growth inhibition and displays tumor regression at the dose of 25 mg/kg/BID.
SAR439859 (3 mg/kg for iv and 10 mg/kg for po) shows a low to moderate clearance in the three animal species tested (0.03-1.92 L/h•kg), low to moderate volume of distribution (Vss=0.5-6.1 L/kg), and good bioavailability (54-76%) across species. It is noticed that T1/2 was variable across species (1.98 h in mouse, 4.13 h in rat and 9.80 h in dog).

Animal Model: Nu/nu mouse with MCF7 tumor xenograft model
Dosage: 2.5, 5, 12.5, 25 mg/kg
Administration: Orally; twice daily for 30 days
Result: Exhibited substantial tumor-growth inhibition and displayed tumor regression at the dose of 25 mg/kg/BID.
Animal Model: Mouse, rat and dog
