Animal peptide library refers to a large database established by collecting and cataloguing peptide toxins produced by various toxic animals in nature. These toxins have become valuable resources in the field of drug discovery due to their high selectivity and potent activity against specific molecular targets in organisms.

As a leading biopharmaceutical company, Creative Peptides has a comprehensive library of animal peptides, covering more than 10,000 unique sequences from more than 500 different animal species, including rare and understudied organisms. We have set up a toxic animal collection, peptide active molecule discovery, peptide drug screening, peptide new drug research and development and industrialization team, in-depth exploration of animal peptides, the construction of natural active peptide molecular library, "high throughput + cloud computing" screening platform and AI artificial intelligence platform for peptide drug screening.

Construction of animal peptide library

Characteristics of animal peptides

Venomous animals are widely distributed in nature, including snakes, spiders, scorpions, lizards, fish, and some insects, which use venom for hunting or defense. The peptide toxins in these venors have evolved over time to quickly interfere with the physiology of the prey or predator, such as causing blood clotting, pain and nerve paralysis. Animal peptides tend to have complex molecular structures, including large molecular weights (some exceeding 40 amino acids) and multiple disulfide bonds, which increase their functional diversity and present challenges for synthesis and analysis.

However, in terms of the patent drug rate, about 50,000 compounds of small molecule drugs can screen out a lead compound; However, based on natural peptides from toxic animals, it is possible to narrow down a single peptide candidate from hundreds of compounds. During the evolution of toxic animals, the peptides in the body were originally more highly active and highly selective. In addition, one reason for the low rate of small-molecule drugs is the side effect caused by off-target, but the peptides are metabolized in the body to produce amino acids, so the metabolites are not toxic.

There are currently about 60 peptide drugs on the market, with sales of $13 billion in 2010, and many more derived from animal toxins are in clinical development. These drugs provide new ways to treat conditions such as chronic pain by mimicking the mechanisms of toxin action, such as blocking pain-related ion channels.

Applications of animal peptide library

Through the high-throughput expression system, it is possible to rapidly build peptide libraries containing thousands of members, such as the more than 8,000 proteins in the conotoxin library, accelerating the process of drug discovery. The library reveals the high specificity and affinity of conotoxin to human ion channels and nervous system receptors, providing a rich library of candidate substances for drug screening, and a powerful tool and potential drug candidate for neuroscience and drug development.

By using innovative methods such as gene recombination technology and antibody fusion strategy, the limitations of traditional synthesis can be overcome to achieve efficient expression and functional optimization of specific peptide toxins. For example, using the unique structure of bovine antibody BLV1H12, which can stably insert a variety of proteins and peptides, the recombinant expression of genes such as Mexican scorpion toxin Vm24 and cobra neurotoxin cobopeptide has been successfully achieved as Kv1.3 inhibitors and long-acting analgesics, respectively.

Certain animal peptides are used in cosmetics to enhance skin health and appearance due to their specific biological activities, such as antioxidant and anti-aging effects.

The animal peptide Library is also an important resource for studying toxin mechanisms, assessing ecological risks and developing detoxification strategies to help scientists better understand the ecological role of toxic animals and how to protect humans and domestic animals from toxins.
