Special Issue Information

Dear Colleagues, 

The upcoming Special Issue "Advances in Peptide Drug Design and Development: from Sequences to Drug Candidates" will explore the research landscape of peptide-based bioactive molecules. Peptides have emerged as versatile motifs to be explored in the drug discovery and development research field, offering unique advantages such as target specificity and low toxicity compared to small molecule counterparts. This Special Issue aims to showcase recent advances in peptide engineering, highlighting strategies such as identifying promising peptide sequences as well as translating them into viable drug candidates. 

We invite researchers in the drug development research field, medicinal chemistry, pharmacology, physiology, molecular biology, and clinicians to contribute their original research findings as well as insights and perspectives on the current trends and challenges in designing peptide-based drug candidates.

The key areas to be addressed include: 

  1. Peptide Sequencing and Screening: Identification of biologically active peptide sequences and essential pharmacophore motifs.
  2. Peptide Modifications and Engineering: Cutting-edge strategies for optimizing sequences to enhance the stability, bioavailability, pharmacokinetics, and pharmacological properties of peptides.
  3. Structural Insights: Exploring the impact of tridimensional structures on peptide activity, employing NMR spectroscopy data, and computational models.
  4. Peptide Synthesis: Advances in synthesis techniques, including solid-phase and microwave-assisted methods, orthogonal chemistry, and late-stage modifications.
  5. Bioconjugation and Drug Delivery: Development of peptide–drug conjugates and strategies for targeted delivery and controlled release.
  6. Peptide-Based Therapeutics: Case studies characterizing the pharmacological properties of peptide-based therapeutics, from in vitro to clinical settings.
  7. Toxicology and Safety Assessment: Methodologies for and challenges in evaluating safety, toxicity, and the immunogenicity of peptide-based drug candidates.
  8. Emerging Technologies: Exploration of innovative technologies, such as mRNA-encoding peptides, CRISPR-mediated therapies, and AI-driven drug design.
  9. Future Perspectives: Insights into the evolving landscape of peptide drug development, including personalized medicine, combination therapies, and addressing unmet medical needs.

Orally administered “tortoiseshell and deer antler gelatin” is a common traditional medicine for patients with osteoporosis or osteoarthritis. From the pepsin-digested gelatin, we previously isolated and identified the osteoblast-stimulating pentapeptide, TSKYR. Its trypsin digestion products include the dipeptide YR, enhancing calcium ion uptake, and tripeptide TSK, resulting in remarkable 30- and 50-fold increases in mineralized nodule area and density in human osteoblast cells. These peptides were chemically synthesized in this study. The composition of deer antler preparations comprises not only proteins and peptides but also a significant quantity of metal ion salts. By analyzing osteoblast growth in the presence of peptide YR and various metal ions, we observed a synergistic effect of calcium and strontium on the effects of YR. Those peptides could also stimulate the growth of C2C12 skeletal muscle cells and human chondrocytes, increasing collagen and glycosaminoglycan content in a three-dimensional environment. The maintenance of bone homeostasis relies on a balance between osteoclasts and osteoblasts. Deer antler peptides were observed to inhibit osteoclast differentiation, as evidenced by ROS generation, tartrate-resistant acid phosphatase (TRACP) activity assays, and gene expression in RAW264.7 cells. In summary, our findings provide a deep understanding of the efficacy of this folk medicine. Full article
