Description

Palazestrant is an antiestrogen and antineoplastic agent.

Uses

Palazestrant is an antiestrogen and antineoplastic agent. Palazestrant can completely inhibit the activity of 17b-estradiol (E2) with IC50 value of 6.4 nM, and inhibit the proliferation of MCF7 and CAMA-1 cells with IC50 value of 1.4-1.6 nM. Palazestrant can inhibit ER+/HER2+ cancer[1][2][3].

in vivo

Palazestrant (0-100 mg/kg/day for 3 days. p.o.) alone or in combination with Palbociclib (HY-50767), Ribociclib (HY-15777) or Alpelisib (HY-15244) can effectively inhibit the proliferation and brain metastasis of ER-positive breast cancer[3].

IC 50

17b-estradiol (E2): 6.4 nM (IC50); ER
