estrogen receptor-alpha (erα)

PAC is a chemical conjugate consisting of an ADCs linker and PROTACs linked to an antibody. When PAC is conjugated to an antibody, it exhibits enhanced degradation of estrogen receptor-alpha (ERα) in comparison to PROTAC alone.

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).

Alpha-Estradiol (Epiestradiol) 是一种雌性激素，可抑制5α-reductase，在雄原性脱发的研究中有潜力。

MPP dihydrochloride is a highly selective antagonist of estrogen receptor alpha (ERα).

Propyl pyrazole triol (PPT) 是雌激素受体 α(ERα)选择性激动剂。它对 ERα 的相对结合亲和力 (ERα: 49%) 比雌激素受体 β (ERβ: 0.12%) 高 410 倍。

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].
