AZD9496 maleate is a potent and selective estrogen receptor ( ERα ) antagonist with IC 50 of 0.28 nM. AZD9496 maleate is an orally bioavailable selective oestrogen receptor degrader (SERD).
In Vitro
The potency of AZD9496 with IC 50 of 0.82 nM, 0.14 nM, and 0.28 nM in ERα binding, downregulation, and antagonism, respectively. AZD9496 significantly inhibits MCF-7 cell growth with EC 50 of 0.04 nM. Selectivity of AZD9496 over other tested nuclear hormone receptors is high: androgen receptor (AR), IC 50 =30 μM; glucocorticoid receptor (GR), IC 50 =9.2 μM; progesterone receptor (PR), IC 50 =0.54 μM. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
Significant tumor growth inhibition is observed as low as 0.5 mg/kg dose in the estrogen-dependent MCF-7 xenograft model, where this effect is accompanied by a dose-dependent decrease in PR protein levels, demonstrating potent antagonist activity. Combining AZD9496 with PI3K pathway and CDK4/6 inhibitors lead to further growth-inhibitory effects compared with monotherapy alone. AZD9496, given once daily orally at 5 and 25 mg/kg produced statistically significant increases in uterine weight compared with the ICI 182780 control (P<0.001) but significantly lower than ICI 47699 (P=0.001) . AZD9496 is also tested in a long-term estrogen deprived model (LTED), using the HCC-1428 LTED cell line that grows in the absence of estrogen and is thought to best represent a model of aromatase inhibition. AZD9496 shows significant activity, with a dose of 5 mg/kg giving tumor regressions in this model. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
