General Description
Tritylthiol-Poly(L-Glutamic Acid) is a functional polypeptide designed as a protected intermediate for preparing thiol-reactive poly(L-glutamic acid) derivatives. The terminal thiol is protected with a trityl (Trt) group, providing excellent stability during synthesis and storage while preventing premature oxidation and disulfide formation.
Following deprotection, the resulting thiol-functionalized poly(L-glutamic acid) readily participates in thiol-maleimide conjugation, thiol-ene click chemistry, disulfide formation, gold surface immobilization, and Michael addition reactions.
The poly(L-glutamic acid) backbone contains multiple pendant carboxylic acid groups that can be activated using EDC/NHS chemistry or peptide-coupling reagents for conjugation with proteins, peptides, antibodies, drugs, polymers, and nanoparticles. The biodegradable polymer backbone and protected thiol functionality make Trt-pGlu an excellent intermediate for preparing advanced drug delivery systems, hydrogels, polymer-drug conjugates, and biomaterials.
