Estrogen Receptors

Elacestrant (RAD1901) is an orally available selective estrogen receptor degrader (SERD) with IC50s of 48 and 870 nM for ERα and ERβ, respectively.

Brilanestrant (GDC-0810, ARN-810??? is a potent ER-α binder (ER-α, IC50 = 6.1 nM; ER-β, IC50 = 8.8 nM), a full transcriptional antagonist with no agonism and displays good potency and efficacy in ER-α degradation (EC50 = 0.7 nM) and MCF-7 breast cancer cell viability (IC50 = 2.5 nM) assays with good selectivity over other nuclear hormone receptors.

RAD1901 is an orally available, selective estrogen receptor degrader (SERD) and selective estrogen receptor modulator (SERM), with potential antineoplastic and estrogen-like activities.

PROTAC ER Degrader-3 is an intermediate for synthesis of PAC. PAC, consists the ADCs linker and PROTACs, conjugated to an antibody. PAC extracts from patent WO2017201449A1, compound LP2. PAC conjugated to an antibody is a more marked estrogen receptor-alpha (ERα) degrader compared to PROTAC (without Ab).

PROTAC ERRα Degrader-1 comprises a MDM2 ligand binding group, a linker and an estrogen-related receptor alpha (ERRa) binding group. PROTAC ERRα Degrader-1 is an estrogen-related receptor alpha (ERRa) degrader.

LSZ-102 is a potent, orally bioavailable selective estrogen receptor degrader with an IC50 of 0.2 nM.

GDC-0927 Racemate (SRN-927 Racemate) is a degrader of estrogen receptor, potently inhibits ER-α activity, with an IC50 of 0.2 nM, and is used in the research of ER-related diseases.

SAR439859 is an orally available, nonsteroidal selective estrogen receptor degrader/downregulator (SERD).
