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。
FKBP12 PROTAC dTAG-7 (dTAG-7) is a heterobifunctional compound that selectively degrades the BET bromodomain transcriptional co-activator BRD4 by connecting BET bromodomains to the E3 ubiquitin ligase CRBN. Additionally, it serves as a degrader of FKBP12F36V when FKBP12F36V is expressed in-frame with a targeted protein.
Bromo-PEG5-phosphonic acid diethyl ester is a polyethylene glycol (PEG)-based linker for PROTAC synthesis[1]. It is utilized in the construction of PROteolysis TArgeting Chimeras (PROTACs), which are heterobifunctional molecules designed to induce protein degradation.
GMBS, a heterobifunctional cross-linker, possesses an N-hydroxysuccinimide (NHS) ester at one end and a maleimide group at the other. It is commonly used in bioconjugation to link amines and sulfhydryls [thiols], forming stable amide and thioether bonds, respectively, which are useful in creating protein and peptide conjugates.
m-PEG4-phosphonic acid ethyl ester is a PEGylation-based linker for the design and synthesis of PROTACs, which are heterobifunctional molecules facilitating targeted protein degradation[1].
m-PEG3-Sulfone-PEG4-propargyl is a polyethylene glycol (PEG)-based prodrug-induced degradation (PROTAC) linker. It is utilized in the efficient synthesis of PROTACs, a class of heterobifunctional molecules designed to selectively target and degrade specific protein targets[1].
Sulfo-SMPB sodium is a non-cleavable heterobifunctional chemical cross-linking reagent that combines N-hydroxysuccinimide ester and maleimide groups. This compound enables the covalent conjugation of molecules possessing amine and sulfhydryl functionalities.
SBA crosslinker is a sulfhydryl and amino reactive heterobifunctional protein crosslinking reagent. SBA protein crosslinker is non-cleavable and is among the shortest amine and sulfhydryl reactive crosslinking reagents known with a spacer arm length of on
SMPB crosslinker is a heterobifunctional protein crosslinking reagent that is reactive toward sulfhydryl and amino groups. The SMPB protein crosslinker is an extended chain length analog of MBS crosslinker. SMPB crosslinker's spacer arm is non-cleavable.
