Product News: ChemBridge Launches New Library of Synthetic Macrocycles

New collection of macrocyclic compounds is designed for hit-finding against difficult targets including antiviral and protein-protein interaction targets.

04 Aug 2017

ChemBridge has developed a diverse, easily modifiable collection of macrocycles intended to be accessible to both industry and academic researchers. The macrocycle library compounds are based on a collection of novel synthetic macrocyclic scaffolds with some based on natural products. ChemBridge chemists developed synthetic strategies for the synthesis and functionalization of macrocyclic compounds and to date have developed over 70 core macrocyclic scaffolds.

The use of synthetic macrocycles is becoming a well-recognized and successful approach for low druggability targets such as antimicrobial, antiviral and protein-protein interaction. Topologically, macrocycles have the unique ability to span large surface areas while remaining conformationally restricted compared to acyclic molecules of equivalent molecular weight. Macrocyclization reduces overall polarity and enhances membrane penetration. Taken together these attributes make macrocycles a powerful approach for any lead discovery program against challenging targets. Macrocycles are typically defined as a carbo- or, more likely, a heterocycle comprising 12 or more heavy atoms and are often perceived as difficult to synthesize and challenging to incorporate chemical diversity. Through focusing on solutions to the synthetic challenges the chemists at ChemBridge® have produced a diverse library of over 6,000 macrocycles that are in stock and available for purchase. 

The current set of more than 6,000 macrocycles represents initial work; the Macrocycle Library will be further expanded to incorporate new core macrocyclic scaffolds leading to new, diverse macrocyclic compounds.
