Endogenous Physiological Pathways

Endogenous Physiological Pathways is a collective term describing the vast array of internal biological processes, including metabolic cycles, signal transduction, and homeostatic regulation, that sustain life (National Center for Biotechnology Information, 2023). This designation does not refer to a specific molecular target such as a protein, enzyme, or ion channel, but rather to the systemic context in which all therapeutic interventions occur. In the pharmaceutical industry, drug discovery is predicated on identifying specific, high-affinity binding sites within these pathways to achieve therapeutic efficacy while minimizing off-target effects (StatPearls, 2023). Because the term encompasses nearly all biological activity, it lacks the specificity required for a target in a drug development pipeline. Consequently, while these pathways are the ultimate site of drug action, they are categorized as biological systems rather than individual therapeutic targets (NIH, 2024). Understanding the interplay between various endogenous pathways is crucial for predicting drug-drug interactions and systemic toxicity during clinical trials.
