7 octynoic acid

7-Octynoic acid (compound 42) serves as a PROTAC linker for synthesizing various PROTACs, composed of two distinct ligands joined by this linker, where one ligand interacts with an E3 ubiquitin ligase and the other binds to the target protein, leveraging the intracellular ubiquitin-proteasome system to selectively degrade target proteins[1].

Fmoc-7-amino-heptanoic acid is an alkane chian with terminal Fmoc-protected amine and carboxylic acid groups. The compound can be used as a PROTAC linker in the synthesis of PROTACs. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond.

Boc-7-Aminoheptanoic acid can be used as a PROTAC linker in the synthesis of PROTACs and other conjugation applicaitons. Boc-7-Aminoheptanoic acid is an alkane chain with terminal carboxlic acid and Boc-protected amino groups. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The Boc group can be deprotected under mild acidic conditions to form the free amine.
