Application

1-(2-(tert-Butoxycarbonyl)-2-azaspiro[3.3]heptan-6-yl)-1H-pyrazole-4-carboxylic acid is useful as a rigid linker in PROTAC development for targeted protein degradation as well as chemical conjugates. Incorporation of rigidity into the linker region of bifunctional protein degraders may impact the 3D orientation of the degrader and thus ternary complex formation as well as optimization of drug-like properties. Developed in partnership with ComInnex.
