Propargyl-PEG1-acid is a PEG-based PROTAC linker can be used in the synthesis of BTK-CRBN PROTACs Ibrutinib(HY-10997)-based PROTAC 4 and PROTAC 5. PROTAC 5 causes the degradation of BTK and induces the degradation of CSK, LYN, and LAT2 at 10 μM. Propargyl-PEG1-acid is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

Description

Propargyl-PEG1-acid is a PEG-based PROTAC linker can be used in the synthesis of BTK-CRBN PROTACs Ibrutinib(HY-10997)-based PROTAC 4 and PROTAC 5. PROTAC 5 causes the degradation of BTK and induces the degradation of CSK, LYN, and LAT2 at 10 μM[1]. Propargyl-PEG1-acid is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

PEGs

 

In Vitro

BTK-CRBN PROTACs act as stoichiometric degraders, resulting in degradation of BTK protein. Degradation of BTK is a result of cereblon E3 ligases family recruitment[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
