Chemists have developed an efficient skeletal editing method for frequently used heteroaromatic structures.
The technique could serve as a means to chemically modify biologically active compounds. Skeletal editing is a modern approach to chemical synthesis. By making precise alterations at the atomic level, researchers are able to directly convert existing drug scaffolds into new, biologically relevant compounds. A team led by chemist Prof Armido Studer from the University of Münster has developed a new strategy based on this technique to swap carbon atoms with nitrogen atoms . The process functions within indole and benzofuran frameworks. These chemical structures, which contain two molecular rings consisting mainly of carbon, are common building blocks of pharmaceuticals and natural products. "This technique expands the synthetic toolbox available for skeletal editing," explains doctoral student Zhe Wang, who carried out most of the experimental work. It represents a step forward in the development of new molecules from established pharmacophores, i.e. the molecular components responsible for pharmacological effects., shows that indoles can be converted into indazoles by swapping C to N atoms. The transformation proceeds through ring-opened intermediates, from which benzimidazoles can also be produced by shifting the nitrogen atom. The same strategy applies to benzofurans, yielding either benzisoxazoles or benzoxazoles, depending on the direction of structural reassembly. These compound classes -- indazoles, benzimidazoles, benzisoxazoles and benzoxazoles -- are known for their biological activity and widespread presence in therapeutics and natural products.A new CRISPR-based gene-editing tool has been developed which could lead to better treatments for patients with genetic disorders.
