H-Glu-OtBu is an organic synthesis intermediate and pharmaceutical intermediate, which can be used in laboratory research and development processes and chemical pharmaceutical synthesis processes.

As a linker for PROTAC (protein degradation targeting chimera), it plays an important role in drug development. PROTAC is a novel drug molecule that acts by inducing degradation of target proteins. H-Glu-OtBu, as a link-agent, can link the target protein to E3 ubiquitin ligase, thereby promoting the ubiquitization and subsequent degradation of the target protein. This mechanism enables PROTAC to achieve efficient and selective degradation of specific target proteins.

Secondly, H-Glu-OtBu can also be used as a connector for ADC (Antibody drug Conjugate). Adcs are a class of drugs that conjugate cellular agents to antibodies via a connector to achieve a precise strike on a specific antigen-expressing cell. H-Glu-OtBu acts as a linker to stably link cellular agents to antibodies while maintaining the stability and biological activity of the ADC. When the ADC binds to the antigen, the cell agent is released into the cell.

In addition, H-Glu-OtBu can also be used to prepare fatty diacid derivatives, which play a key role in the synthesis of insulin analogues. By introducing H-Glu-OtBu, the structure and properties of insulin analogues can be regulated to improve their pharmacodynamic and pharmacokinetic properties.
