WebApr 13, 2024 · Covalent peptidomimetic protease inhibitors have gained a lot of attention in drug development in recent years. They are designed to covalently bind the catalytically active amino acids through electrophilic groups called warheads. Covalent inhibition has an advantage in terms of pharmacodynamic properties but can also bear toxicity risks due … WebCysteine proteases are found in all forms of life and mediate a wide variety of physiological and pathological processes, from the bulk digestion of protein, on the one hand, to highly regulated rate-determining and specific peptide-bond cleavages at the opposite extreme. ... which are routinely included in enzyme assays [1].
