Broad protein substrates

Broad protein substrates is a generic classification used in pharmacological databases such as ChEMBL (Target ID: CHEMBL2367076) to categorize assays involving the non-specific degradation of various proteins (ChEMBL Database, 2024). This term does not refer to a single molecular entity but rather to the collective group of polypeptides that can be hydrolyzed by broad-spectrum proteases like papain or bromelain (StatPearls, 2023). In clinical practice, drugs interacting with these substrates are typically exogenous enzymes used for digestive support or wound debridement, where they facilitate the breakdown of necrotic tissue or dietary proteins (PubChem, 2024). Because it encompasses an undefined variety of proteins, it is not considered a discrete therapeutic target for drug discovery (ChEMBL Database, 2024). Instead, it serves as a functional descriptor for the activity of hydrolases that lack sequence specificity (StatPearls, 2023). This lack of specificity means that while these substrates are useful for general enzymatic studies, they do not provide the precision required for modern targeted therapies.
