Abstract:

Aminopeptidase N (APN/CD13) of the M1 family is a broad specificity enzyme that is intimately involved in tumor angiogenesis and metastasis. Asparagine-glycine-arginine (NGR) is a tumor-homing tripeptide, which can selectively combine with APN/CD13 that is overexpressed on the surface of some tumor cells. Various anti-tumor drugs can be conjugated to NGR to improve selectivity, efficacy, and to decrease drug toxicity. In this study, a tripeptide NGR(NO2) was synthesized and conjugated with 5-fluorouracil. The anti-tumor activities of this new prodrug were evaluated in vivo. More significant anti-tumor effects were observed over the parent 5-fluorouracil.

More about this publication?
  • Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
