Pancreatic cancer (PC, mostly pancreatic ductal adenocarcinoma, PDAC) is one of the most aggressive and dangerous cancerous diseases with a very poor prognosis and high mortality. Thus, there is a need to develop new and more effective treatments to cure this disease. Among the many newly developing therapeutic approaches, peptide-based drug targeting provides a new tool for this purpose. CD BioSciences offers peptide drug development services for PC, including peptide screening, peptide design and optimization, custom peptide synthesis, and peptide validation and evaluation.
Overview of anti-tumor peptides
Peptides can also be obtained through proteolysis of animal and plant proteins, artificial chemical synthesis, and bioengineering in three ways. Based on rational approaches with high specificity, they can be designed to bind and modulate protein interactions of interest. Peptide sequences can also be easily regulated as they are easily synthesized by chemical or molecular biology techniques. Since many sequences, structures and pattern interactions for oncogenic proteins are available, peptides can be specifically designed as inhibitors of these interactions. With the incorporation of different stable structural modifications and new drug delivery systems, short peptides have proven to be promising drugs for cancer therapy. Peptides are attracting attention in the development of anti-tumor drugs because of their targeting, safety, and specificity. Based on their mechanism of action, anti-tumor peptides can be divided into inhibitory, necrosis-inducing, and pro-apoptotic peptides.
Benefits of short peptides
- Short peptides have several important advantages over full-length proteins and antibodies: less immunogenic, more stable ex vivo, higher activity, greater specificity and affinity, easier to synthesize and modify, and lower cost.
- In comparison with small organic molecules, peptides have higher efficacy and specificity, and better biocompatibility.
- Since short peptides have a highly selective mechanism of action and the main products of peptide metabolism are amino acids, they have lower toxic effects.
