Methods for the generation of large combinatorial macrocycle libraries

Sevan Mleh Habeshian

Macrocycles are an attractive class of molecules due to their good binding properties and yet rather small size that allows, in many cases, crossing membranes to reach intracellular targets. In comparison to classical small molecule drugs, macrocycles are ...

Macrocycle synthesis strategy based on step-wise “adding and reacting” three components enables screening of large combinatorial libraries

Christian Heinis, Gerardo Turcatti, Julien Bortoli Chapalay, Alessandro Angelini, Alessandro Zorzi, Jonathan Patrice Vesin, Ganesh Kumar Mothukuri, Sangram Shivdas Kale, Kaycie Marie Butler, Carl Leonard Stenbratt

Macrocycles provide an attractive modality for drug development, but generating ligands for new targets is hampered by the limited availability of large macrocycle libraries. We have established a solution-phase macrocycle synthesis strategy in which three ...
