Description
Technical Field
The invention relates to a glutamic acid derivative with a photosensitive p-methoxybenzoyl group on a side chain and a synthesis method and application thereof, which are compatible with solid phase synthesis, and belong to the technical field of protein synthesis.
Background
Photocage peptides and proteins, whose biological functions are inhibited by photocleavable protecting groups, can regain their activity under light irradiation. These compounds are widely used to detect and elucidate complex biological processes because the illumination can be precisely controlled in space, time and amplitude in a non-invasive manner. Side chain cage forms of serine, threonine, tyrosine, cysteine, lysine, arginine, glutamine, aspartic acid, and glutamic acid (Glu) have been reported. Among these functions, carboxylic acid groups play an important role in protein activity and in protein interactions with other biological macromolecules or small molecules. Peptide and protein derivatives capped with carboxylic acid moieties have been developed to study biochemical mechanisms and protein-protein/ligand interactions.
For example, an article (J.Am.chem.Soc.1991, 113, 2758-2760.) reports a method for triggering an enzymatic reaction using photoactivatable bacteriophage T4 lysozyme containing aspartyl b-nitrobenzyl ester in the active site Asp 20. Similarly, an article (J.Am.chem.Soc.2013, 135, 4580-4583.) reports the introduction of a photolabile blocking group into the basic C-terminal carboxylate of a PDZ domain ligand to exploit synaptic PDZ domain-mediated interactions.
Generally, caged peptides are synthesized by standard Solid Phase Peptide Synthesis (SPPS) methods, which provides the greatest flexibility in designing caged peptides and protein derivatives. The article (J.biomed.Mater.Res.PartA 2013,101A, 787-796) produced a photoactivatable peptide containing "RGD" by modifying the carboxylic acid of Asp with 2-nitrobenzyl (2-NB). However, the photochemical and photophysical properties of 2-NB limit its further use in biological processes. The article (Peptides 2007,28,1074-1082.) reported 4,5-Dimethoxynitrobenzyl (DMNB) has improved photochemical properties, but failed to incorporate into the side chain carboxylic acid during Fmoc SPPS due to side reactions of Asp (ODMNB) and Glu (ODMNB) to form asparagine and pyrrolidone. The article (Tetrahedron lett.,56 (2015), pp.4582-4585) reports a method for the synthesis of photocage peptides by modification of the derivative Asp and Glu with 4-methoxy-7-nitroindoline (MNI). MNI cages have excellent photochemical properties and fast photolysis kinetics, but the synthetic steps are cumbersome.
Thus, there remains a need for new Fmoc-compatible methods to produce side chain carboxy-blocked peptides/proteins with good photochemical properties simply and quickly.
