Parallel Chemistry and Compound Libraries

Compound libraries for successful drug discovery projects

  • Screening libraries
  • Focused and targeted libraries
  • Fragment collection
  • Hit and SAR expansion arrays
  • Under-populated druglike chemical space
  • Novel sp3-rich scaffolds
The quality of compound libraries affect the fate of a drug discovery project – Taros’ compound library designs target underpopulated druglike chemical space. High quality compound libraries requires chemical creativity and profound synthesis knowledge to achieve the highest possible molecular diversity. Our efficient production process reduces the costs per compound by utilising parallel synthesis and high throughput purification. Taros has established a highly successful and efficient library and parallel synthesis group as evidenced by our outstanding contribution to the European Lead Factory (ELF), for which we successfully designed, synthesized and delivered over 40,000 library compounds from more than 100 chemical scaffolds. Moreover, in our role as an ELF executive member and head of the chemistry consortium, Taros was responsible for managing the entire chemistry consortium (7 companies and 10 academic groups throughout Europe) to develop and produce the ELF public compound collection consisting of 200.000 novel and lead-like compounds.

Druglike physicochemical properties and medicinal chemistry relevance

Taros unlocks underexplored chemical space by encoding natural product derived topology into novel scaffolds. Our library designs show a remarkably lower clogP, an increased number of chiral atoms and a significantly higher fraction of sp3-hybridised carbons (fsp3). In contrast to commercially available screening libraries, the high 3D character is engineered into the scaffolds and does not solely derive from a favourable decoration at its periphery. Involving our experienced medicinal chemists guarantees that our scaffolds are decorated with chemical building blocks that are of medicinal chemistry relevance. In addition, our scaffolds bear a high number of diversity points for systematic exploration of the chemical space around the design and hence rapid lead identification.
  • Optimal sampling of chemical space by cheminformatics
  • Creativity in the design and the reduction to practice
  • Translation of known methods to novel scaffolds
  • Development of new routes to hitherto inaccessible scaffolds
  • Wide range of reactions established for parallel synthesis
  • Awareness of possibilities AND limitations
