PROTAC ERα Degrader-1 is a chemical compound. It consists of a ubiquitin E3 ligase binding group, a linker, and a protein binding group. This compound serves as a degrader of estrogen receptor-alpha (ERα).
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。
PROTAC ER Degrader-2 serves as a synthesis intermediate for the production of PAC, a compound that incorporates the ADCs linker and PROTACs, which are subsequently conjugated to an antibody. PAC, exhibits a greater capability to degrade estrogen receptor-alpha (ERα) compared to PROTAC (without the presence of an antibody)[1].
PROTAC ER Degrader-3, an intermediate for the synthesis of PAC, specifically compound LP2. PAC serves as the linker for ADCs and PROTACs that are conjugated to an antibody. Notably, when PAC is conjugated to an antibody, it exhibits enhanced degradation of estrogen receptor-alpha (ERα) compared to PROTAC alone [1].
