activity based protein profiling drug discovery

Wang S(1), Tian Y(1), Wang M(1), Wang M(2), Sun GB(1), Sun XB(1). A reactive-cysteine profiling method, known as isoTOP-ABPP, has the potential to aid in two key aspects of covalent irreversible inhibitor discovery: (1) to identify ligandable cysteines for covalent modulation of protein function; and, (2) to evaluate both on and off-target cysteine engagement so as to minimize risks associated with off-target drug toxicity . Specifically, both approaches can be applied in critical steps of drug development, such as therapy target discovery, high‐throughput drug screening and target identification of bioactive molecules.
