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 is a relative configuration of PROTAC ERRα Degrader-1, which is an estrogen-related receptor alpha (ERRa) degrader. PROTAC ERRα Degrader-1 consists of an MDM2 ligand binding moiety, a linker and an ERRa binding moiety [1].
PROTAC ERRα Degrader-3 is a highly effective and selective von Hippel-Lindau-based ligand that efficiently degrades the ERRα protein. At a concentration of 30 nM, this compound exhibits a remarkable degradation capability, reducing the ERRα protein levels by >80%. Importantly, PROTAC ERRα Degrader-3 shows no activity against the ERRβ and ERRγ proteins.
Vepdegestrant (ARV-471) 是一种具有选择性和高效性的雌激素受体(ER,ESR1)PROTAC 降解剂,对 ER 蛋白具有强效降解能力。Vepdegestrant 通过直接降解 ER 蛋白而非单纯拮抗其活性,有效抑制 ER 信号通路,在 ER 阳性(ER⁺)乳腺癌中表现出显著的抗肿瘤活性,DC50 值约为 2 nM,尤其对 ESR1 突变型肿瘤同样具有良好效果。
