Dihydrofolate reductase inhibitory peptides screened from a structured designed β-loop peptide library displayed on phage.

چکیده
Enzyme inhibitory peptides with a loop structure stabilized using an antiparallel β-sheet scaffold (β-loop peptide) were obtained from a designed peptide phage library. Human dihydrofolate reductase (hDHFR) was used as the target enzyme. The obtained β-loop peptides were competitive inhibitors of hDHFR with micromolar inhibition constants and dissociation constants.

متن کاملDiscovery of Novel Peptidomimetics for Brain-Derived Neurotrophic Factor using Phage Display Technology
Brain-Derived Neurotrophic Factor (BDNF) is a neuroprotectant candidate for neurodegenerative diseases. However, there are several clinical concerns about its therapeutic applications. In the current study, we selected BDNF-mimicking small peptides from phage-displayed peptide library as alternative molecules to the clinical challenges. The peptide library was screened against BDNF receptor (Ne...

Random peptide libraries (RPL) displayed on the surface of filamentous bacteriophages have been extensively used as a tool to map epitopes or to identify antigenic mimics (mimotpoes) of disease-specific monoclonal antibodies or polyclonal sera. These RPL are engineered by the insertion of degenerate oligonucleotides, encoding a specific number of random amino acids, in frame with a bacteriophag...
متن کاملIdentification of a Novel Tumor-Binding Peptide for Lung Cancer Through in-vitro Panning
Tumor-targeted therapies are playing growing roles in cancer research. The exploitation of these powerful therapeutic modalities largely depends on the discovery of tumor-targeting ligands. Phage display has proven a promising high throughput screening tool for the identification of novel specific peptides with high binding affinity to cancer cells. In the present study, we describe the use of ...
