With unparalleled expertise in the field of small molecule drug discovery, Creative Biolabs is fully competent and dedicated to offering one-stop Protein Degraders service which holds significant promise for exploring previously “undruggable” proteome in the area of drug discovery. To develop an efficient Protein Degraders, we offer our clients with molecule design service including ligand design for target protein, ligand screening for E3 ligase, as well as chemical linker design and optimization.
To overcome the limitations of traditional therapeutic approaches for disordered proteins, PROteolysis TArgeting Chimera (Protein Degraders) was developed with selective manipulation of spatial and temporal disease-causing proteins. Protein Degraders degrades the target proteins at the post-translational level. Even though Protein Degraders owns promising therapeutic potential, it hasn't been broadly pushed into clinical trial stages. One of the key challenges is molecule discovery. For three components of Protein Degraders: a target-protein-binding moiety, a ligand for recruiting the degradation machinery, and a chemical linker, they are all critical for the efficiency of Protein Degraders. We already know that Protein Degraderss with different chemical linker types, locations and lengths exhibit obviously different efficiencies for target degradation (see Fig.1). Herein, linker design and optimization may expand the Protein Degraders toolbox, and explore new possibilities for the broad application of Protein Degraders in various diseases.

The Protein Degraders linker connects two functional heads: a ligand for E3 ligase recognition and a ligand for target protein recognition. It plays a vital role in efficient ubiquitination of the target protein and its ultimate degradation. To date, several kinds of linkers have been reported and applied in Protein Degraders ternary complexes formation, such as PEG linker, Alkyl linker, and “click chemistry” linker. In addition, linker length can be optimized by fine-tuning the distance between two participating partner proteins - target protein and E3 ligase to achieve maximal interaction. The length can be varied from 12-carbon to over 20-carbon. Furthermore, linker position can be optimized to determine various derivatizations to ensure a maximal binding affinity. Empowered by our advanced chemical molecule design and synthesis platform, Creative Biolabs offers our clients with linker design and optimization services based on different linker types, lengths, and positions.
To expand the broad application of Protein Degraders in a wide range of diseases, Creative Biolabs has explored a variety of methodologies in Protein Degraders design to investigate and develop an ideal Protein Degraders for our worldwide numerous clients. Both customized design/optimization and spot products are achievable in Creative Biolabs. To achieve the best efficacy, we do recommend our one-stop Protein Degraders design service.
