CLS-logo.png Concept Life Sciences offer a range of services important to any PROTAC® development program. Our Medicinal, Synthetic and Computational Chemists, ADME Scientists and Biologists work closely together, allowing a flow of data and ideas between departments to help you accelerate your design-make-test cycle time.

PROTAC design and synthesis

Targeted protein degradation using PROTACs and SNIPERs has emerged as a new modality in drug discovery. These heterobifunctional molecules maintain some of the advantages of small molecules, differentiating them from other therapeutic approaches such as antisense oligonucleotides, siRNA or CRISPRCas9.

However, they still represent a class of molecules which deviate from the Lipinski ‘Rule of 5’ properties associated with classical oral drugs. Working with PROTACs therefore presents novel challenges in terms of design, synthesis, purification and biological evaluation. Our chemists have significant experience of working with Cereblon, VHL and IAP-based PROTACs that we can bring to bear on some of these challenges. We have established a library of linkers available in house, along with the knowledge and expertise on linker design and synthesis to accelerate your PROTAC program.

Understanding the biology

Concept Life Sciences biology teams utilize state-of-the-art technologies that enable real-time characterization of both PROTAC efficacy and mechanism of action, addressing key questions to accelerate PROTAC development, profiling and guidance of chemical structure−activity relationships. We can effectively measure not only the extent of target protein degradation, but also answer important mechanistic questions such as: 

  • Does the PROTAC enter the cell? 
  • What is the order of binding of the PROTAC to the target protein and the E3 ubiquitin ligase?
  • Does the target protein become ubiquitinated? 
  • Does this ubiquitination drive the protein to be degraded by the proteasome?

In addition, we offer SPR assays to measure the kinetics of PROTAC ternary complexes and elucidate the important kinetic parameters that drive effective target degradation.

ADME profiling

Concept Life Sciences offer a range of in vitro ADMET and in vivo DMPK services, delivering high quality, accurate and reproducible data. In addition to our core service of validated robust assays, we can modify and/or customize your assay design, ensuring a science-led, flexible and quality-driven approach which is important for atypical molecules such as PROTACs. We will help you make technical choices or strategic decisions on test compound characterization, SAR generation and optimization of compound design, supporting you in de-risking your best route to clinic.

Computational modeling for PROTAC design

Computational modeling of your Protein of interest, PROTAC and E3 ligase, can facilitate the design of the best vectors and linker lengths. With state-of-the-art modeling software, we can provide you structure based drug design (SBDD) support to prioritize and identify the best PROTAC design ideas.
