In the current active exploration of developing new therapeutic molecules and carrier systems using cell-penetrating peptides (CPPs) in the biotechnology and pharmaceutical industries, CD ComputaBio stands out with its rich experience and advanced computational platforms, providing professional cell-penetrating peptide computational design services to the biotechnology and pharmaceutical sectors.

Introduction to Cell-Penetrating Peptides

Cell-penetrating peptides (CPPs) are short peptides that efficiently cross cell membranes, preserving cellular integrity. They enable the delivery of bioactive molecules, therapeutics, and theranostic agents into cells. This is crucial for macromolecules, which struggle to permeate membranes. Research highlights CPPs as excellent tools for intracellular delivery of oligonucleotides, siRNA, anticancer drugs, bioimaging agents, DNA, nanoparticles, proteins, and other peptides. Their ability to enhance intracellular transport is vital for advancing drug delivery and therapeutic applications.

In Silico Cell-Penetrating Peptide Design

Cell-penetrating peptides are attracting significant attention due to their multifunctional, customizable, and 'Trojan horse' delivery properties that can evade the immune system. However, the current rational design process is limited, requiring multiple rounds of peptide synthesis and wet lab validation, which is costly. Artificial intelligence brings new opportunities to its design, which can predict its physicochemical properties, secondary structures, and in vivo behaviors such as toxicity and peptidase degradation. By using machine learning to predict the penetration ability of amino acid sequences, it is expected to reduce development costs and increase delivery success rates.
