m-PEG10-alcohol, also known as Decaethylene glycol monomethyl ether, is a non-cleavable 10 unit PEG ADC linker utilized in the synthesis of antibody-drug conjugates (ADCs)[1]. Additionally, m-PEG10-alcohol serves as a PEG-based PROTAClinker, enabling its application in the synthesis of PROTACs[1].
Propargyl-PEG1-acid, a PEG-based PROTAClinker, enables the synthesis of BTK-CRBN PROTACs, specifically Ibrutinib-based PROTAC 4 and PROTAC 5. At a concentration of 10 μM, PROTAC 5 facilitates the degradation of BTK and induces the degradation of CSK, LYN, and LAT2[1].
cIAP1 Ligand-Linker Conjugates 10 comprise of an IAP ligand and a PROTAClinker, which facilitates the design of SNIPERs. These conjugates incorporate an IAP ligand that interacts with the E3 ubiquitin ligase, and a PROTAClinker. SNIPERs can be developed using cIAP1 Ligand-Linker Conjugates 10.
Pomalidomide-PEG1-C2-N3 is a compound that has been synthesized as a conjugate of an E3 ligase ligand-linker. This compound incorporates the cereblon ligand based on Pomalidomide and a 1-unit PEG linker, which are commonly used in PROTAC technology. Utilizing Pomalidomide-PEG1-C2-N3, it is possible to design a selective CDK6 PROTAC degrader known as CP-10. CP-10 effectively induces the degradation of CDK6, displaying a DC50 value of 2.1 nM[1].
Palbociclib-propargyl, a PROTAC ligand targeting the protein CDK6, connects to the CRBN ligand through a PEG linker to form PROTAC CP-10. CP-10 exhibits a potent DC50 value of 2.1 nM against CDK6[1].
Desmethyl-QCA276, the QCA276-based moiety, binds to cereblon ligand via a linker to form PROTAC to degrade BET. QCA276 is a BET inhibitor with an IC50 of 10 nM, and with a Ki of 2.3 nM[1].
ND1-YL2 is a peptide-based PROTAC®Degrader of steroid receptor co-activator 1 (SRC-1; also known as nuclear receptor coactivator 1, NCOA1). ND1-YL2 is composed of a stapled peptide that binds SRC-1 (YL2) joined by a linker to a tetrapeptide that binds UBR box domains. Upon ternary complex formation, SRC-1 is polyubiquitinated and subsequently degraded via the N-degron pathway. This Degrader induces dose-dependent degradation of SRC-1 in the MDA-MB-231 triple negative breast cancer cell line (DC50 = 10 μM), and binds to the PAS-B domain of SRC-1 (Ki = 320 nM). ND1-YL2 inhibits MDA-MB-231 cell migrationin vitro, and suppresses metastasis of MDA-MB-231 cellsin vivo.
