errα

PROTAC ERRα ligand 1 is an estrogen-related receptor α (ERRα) antagonist with IC50 values of 0.04 μM for ERRα and 2.8 μM for ERRγ.

ERRα Ligand-Linker Conjugates 1 refers to a chemical compound that consists of a ligand targeting estrogen-related receptor alpha (ERRα), and a PROTAC linker that facilitates the recruitment of E3 ligases MDM2. It finds utility in the synthesis of a range of PROTACs, including one known as PROTAC ERRalpha Degrader-1. With its capability to induce degradation of ERRα, PROTAC ERRalpha Degrader-1 functions as an ERRα degrader[1].

PROTAC ERRα Degrader-2 is a compound consisting of an MDM2 ligand binding group, a linker, and an estrogen-related receptor alpha (ERRα) binding group. This compound is designed to specifically degrade estrogen-related receptor alpha (ERRα), acting as an ERRα degrader[1].

(rel)-PROTAC ERRα Degrader-1, a relative configuration of PROTAC ERRα Degrader-1, is an estrogen-related receptor alpha (ERRα) degrader comprising an MDM2 ligand binding moiety, a linker, and an ERRα binding moiety [1].

PROTAC ERRα Degrader-3 is a highly effective and selective von Hippel-Lindau-based ligand that efficiently degrades the ERRα protein, reducing its levels by >80% at a concentration of 30 nM. Notably, this compound shows no activity against the ERRβ and ERRγ proteins.

PROTAC ERRα ligand 2 is an inverse agonist for the estrogen-related receptor α (ERRα) with an IC50 of 5.67 nM.

Vepdegestrant (ARV-471) is an estrogen receptor (ER) α PROTAC molecule that degrades ER in ER-positive breast cancer cell lines with a DC50 of approximately 1 nM. It can reduce the expression of classically regulated ER target genes and inhibit the growth of ER-dependent cell lines (including those expressing ESR1 variants, such as Y537S and D538G) by degrading ER.

ERD-3111 (Compound 44), an orally active PROTAC ERα degrader (DC50: 0.5 nM), exhibits efficacy in inhibiting tumor growth in both the parental MCF-7 xenograft model harboring wild-type ER and two ESR1-mutated mouse models. This compound has utility in the investigation of ER+ breast cancer [1].

(S,R,S)-AHPC-C5-NH2, also known as VH032-C5-NH2, is a synthetic E3 ligase ligand-linker conjugate. This compound combines the VH032-based von Hippel-Lindau (VHL) ligand with a linker, enabling it to function as a PROTAC degrader for estrogen-related receptor α (ERRα).

(S,R,S)-AHPC-C7-amine, also known as VH032-C7-amine, is a chemically synthesized conjugate that serves as an E3 ligase ligand-linker, combining the VH032-based VHL ligand with a specific linker for the degradation of estrogen-related receptor α (ERRα) PROTAC.
