Usage

Uses

Used in Pharmaceutical Industry:
1-(TERT-BUTOXYCARBONYL)-3-(1-PIPERAZINYL)AZETIDINE is used as a reactant for the preparation of allele-specific inhibitors that target the mutant KRAS G12C protein. This application is significant because the compound plays a crucial role in the development of targeted therapies for cancer treatment.
The mutant KRAS G12C protein is a common genetic mutation found in various types of cancer, including non-small cell lung cancer, colorectal cancer, and pancreatic cancer. By inactivating this specific mutation through a trapping mechanism, the inhibitors synthesized using 1-(TERT-BUTOXYCARBONYL)-3-(1-PIPERAZINYL)AZETIDINE can potentially lead to the suppression of tumor growth and improved patient outcomes.

MODULATORS OF PROTEOLYSIS AND ASSOCIATED METHODS OF USE

The present disclosure relates to bifunctional compounds, which find utility as modulators of Kirsten rat sarcoma protein (target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a Von Hippel-Lindau, cereblon, Inhibitors of Apotosis Proteins or mouse double-minute homolog 2 ligand which binds to the respective E3 ubiquitin ligase and on the other end a moiety which binds the target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aggregation, accumulation, and/or overactivation of the target protein are treated or prevented with compounds and compositions of the present disclosure.
