| | SAR-439859 Usage And Synthesis |
| Uses | SAR439859 (compound 43d) is an orally active, non-steroidal, and selective estrogen receptor degrader (SERD). SAR439859 is an effective ER antagonist with ER degradation activity, an EC50 of 0.2 nM. SAR439859 can show potent anti-tumor effects and limited cross-resistance in ER+ breast cancer. | | in vivo | 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[1].
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)[1].
| Animal Model: | Nu/nu mouse with MCF7 tumor xenograft model[1] | | 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[1] | | Dosage: | 3 mg/kg (iv) and 10 mg/kg (po) (Pharmacokinetic Analysis) | | Administration: | Iv or po | | Result: | Showed a low to moderate clearance in the three animal species tested (0.03-1.92 L/hkg), low to moderate volume of distribution (Vss=0.5-6.1 L/kg), and good bioavailability (54-76%) across species.
