“Pain begone!”



RUB researchers decode the interplay between enkephalins and pain receptors
Metal complex arrests elusive messenger

“Pain begone!” In order to send out this signal, the human body produces tiny messenger molecules that dock to certain receptors. Using traditional biochemical methods, this interaction between the messengers, so-called enkephalins, and opioid receptors is very difficult to study. An interdisciplinary team of biochemists and inorganic chemists at the Ruhr-Universität Bochum (RUB) has now succeeded in identifying the structure of an enkephalin in solution and to track its interaction with the opioid receptor in detail. The analysis provides a new, precise starting point for the development of drugs meant to combat specific types of pain. This discovery is featured in the cover story of the “Dalton Transactions” journal.
