The fоllоwing is аn excerpt frоm а recent scientific publicаtion:“In medicinal chemistry, understanding how bioactive molecules interact with their target can help to explain structure‑activity relationships (SAR) and improve potency of lead compounds. In particular, computational analysis of protein‑ligand complexes can help to unravel key interactions and guide structure‑based drug design.... potency optimization efforts are often focused on targeting these interactions.” How is understanding noncovalent interactions used in lead optimization?

The fоllоwing is аn excerpt frоm а recent scientific publicаtion:“Covalent inhibitors can achieve exquisite potency and durable target occupancy through a combination of covalent and noncovalent interactions. Drugs that possess a covalent mechanism‑of‑action encompass recent blockbusters (Clopidogrel) as well as early cornerstones of modern medicine (aspirin and penicillin). Despite this well‑documented history and the advantages from sustained target engagement, pharmaceutical companies have traditionally shied away from covalent drug programs due to concerns about potential idiosyncratic toxicity. However, clinical successes over the past decade (e.g. Ibrutinib), along with improvements in technologies used throughout the drug discovery pipeline, have reignited broad interest in this class of therapeutics.” What key advantage of covalent inhibitors is emphasized here in drug discovery?
