aspartimide-formation-peptide-synthesis The cRGD peptide, a cyclic Arg-Gly-Asp sequence, is a highly specific peptide that has garnered significant attention in biomedical research due to its potent affinity for integrin receptors, particularly $\alpha_v\beta_3$作者：C Wängler·2010·被引用次数：114—Under these conditions, the amino function of thecRGD peptidereacts selectively with the active ester of SFB to give the product in good .... These integrins are often overexpressed on the surface of various cancer cells and in tumor vasculature, making the cRGD peptide an invaluable tool for targeted drug delivery and imaging. Its ability to selectively bind to these receptors allows for the precise localization of therapeutic agents or diagnostic probes directly to diseased sites, minimizing off-target effects and enhancing treatment efficacy.

The Role of cRGD in Targeted Therapies

The primary application of the cRGD peptide lies in its use as a targeting ligand for nanomedicines and other therapeutic delivery systems. By conjugating the cRGD peptide to the surface of nanoparticles, liposomes, or other drug carriers, researchers can effectively direct these systems to tumor cells or angiogenic blood vessels. For instance, cRGD-installed micellar nanomedicines loaded with chemotherapeutic agents like epirubicin have demonstrated enhanced antiglioblastoma activity.DSPE-PEG2000-cRGD is a PEG compound which composed of DSPE and an αvβ3 targeting peptide (cRGD).cRGD peptidecan specifically bind to αvβ3 on the surface of ... Similarly, cRGD-conjugated nanocarriers are being explored for the targeted delivery of chemotherapeutic drugs and for imaging purposes, offering a promising avenue for more effective cancer treatment. The development of cRGD-PEG-NH2 and other functionalized derivatives further expands the versatility of cRGD peptide in creating sophisticated drug delivery platforms.
