aDdressing Antimicrobial REsistance by innovative drug design targeting protein degradation (DARE)

PRIN 2022 PNRR Milelli

Abstract

Addressing antimicrobial resistance by innovative drug design targeting protein degradation AntiMicrobial Resistance (AMR) represents one of the most challenging global Public Health issue, accounting for at least 1.2 M deaths worldwide, fuelled by a drying pipeline of antibiotics R&D; and the rapid diffusion of multidrug-resistant isolates. Meanwhile, the discovery of heterobifunctional molecules, able to recruit the eucaryotic proteasome to trigger the specific degradation of virtually any protein of interest (POI), has started a new era for medicinal chemistry. Such molecules, named PROTACs (PROteolysis-TArgeting Chimeras), already reached the stage of clinical development (e. g. androgen and estrogen receptor-targeting). Recent research demonstrated that protein targeted degradation can be achieved in Gram-positive bacteria, through the design of molecules bearing on one side a ligand of the POI and on the other a degron signal recognized by the ClpCP degradation machinery. Our project aims to reposition the PROTAC approach for the design of innovative and groundbreaking first-in-class compounds targeting protein degradation in Gram-negative bacteria, and therefore to establish proof of concept and feasibility of this promising approach, representing an interesting alternative to classical antibiotics.
