The fоllоwing is аn excerpt frоm а recent scientific publicаtion:“The present art of drug discovery and design… with nearly 30% of the marketed drugs targeting enzymes known to act by covalent inhibition. These types of inhibitors derive their activity from both non‑covalent interactions and the formation of the covalent bond between the inhibitor and the target protein. The covalent drugs typically have much stronger binding affinity with the targets because of the covalent linkage formed between the ligand (electrophilic) and the target (nucleophilic), hence stronger potency while maintaining a pharmaceutically favoured small molecule size. Covalent interaction with the target protein has the benefit of prolonged duration of the biological effect.” According to this excerpt, which combination contributes most to the potency and duration of action of covalent inhibitors?

The fоllоwing is аn excerpt frоm а recent scientific publicаtion:“In this study, we adopted the fragment‑based drug design approach, introducing a novel methodology to extract noncovalent and covalent fragments according to distinct three‑dimensional (3D) interaction modes from noncovalent and covalent compound libraries. Additionally, we systematically replaced existing ligands with rational fragment substitutions, based on the spatial orientation of fragments in 3D space. Furthermore, we adopted a molecular generation approach to create innovative covalent inhibitors. This process resulted in the recombination of a noncovalent compound library and several covalent compound libraries… exhibiting superior performance in terms of molecular scaffold diversity… provides valuable resources for virtual screening of covalent and noncovalent drugs targeting similar molecular targets.” What does this fragment‑based design approach combine to support drug discovery?
