Multiple specific protein targets

The term 'Multiple specific protein targets' is a collective designation used in pharmacological databases and clinical research to describe therapeutic agents that interact with a variety of distinct molecular entities rather than a single, defined protein (ChEMBL Database, 2024). This classification is frequently applied to drugs exhibiting polypharmacology, such as multi-kinase inhibitors or broad-spectrum immunomodulators, where the clinical efficacy is derived from the simultaneous modulation of several signaling pathways. Because this term does not refer to a specific gene product, it lacks a unique biological sequence, structure, or localized physiological role. In drug development, targeting multiple proteins can be a deliberate strategy to overcome redundancy in disease pathways, particularly in oncology and complex inflammatory conditions (Nature Reviews Drug Discovery, 2019). However, this approach also increases the complexity of safety profiles, as broad activity often leads to a higher incidence of off-target toxicities and complicates the identification of specific patient selection biomarkers.
