Maybridge specialises in producing innovative heterocyclic chemical building blocks for drug discovery chemistry. Included in our collection of over 12,000 building blocks is a unique and expanding range of Reactive Intermediates, sets of minimally substituted building blocks sharing a common ring structure, each functionalised with a selection of the most synthetically useful reactive groups. The Maybridge Screening collection consists of over 56,000 organic compounds, largely produced by us at Maybridge. These are individually designed compounds, produced by innovative synthetic techniques, based on over 45 years of experience in heterocyclic chemistry.
