I. Introduction to Yisaipu (Etanercept)

A. Overview of Yisaipu (Etanercept)

Yisaipu, corresponding to DrugBank ID DB17076, is the international nonproprietary name (INN) for Etanercept. Etanercept is a significant biopharmaceutical product, classified as a dimeric fusion protein. Its molecular architecture is a key determinant of its function: it comprises the extracellular ligand-binding portion of the human 75-kilodalton (p75) tumor necrosis factor receptor (TNFR) linked to the Fc (fragment crystallizable) region of human immunoglobulin G1 (IgG1). This engineered structure endows Etanercept with the ability to specifically bind to and neutralize the activity of tumor necrosis factor-alpha (TNF-α), a pivotal pro-inflammatory cytokine implicated in the pathogenesis of numerous inflammatory diseases.
