Endoproteeside

Endoproteeside is a fictional chemical concept described in speculative chemistry and theoretical biology as a selective inhibitor of intracellular endoproteases. The name blends endo- (inside), prote- (protease), and -side, following conventions used for hypothetical protease inhibitors. In proposed models, endoproteeside is a small organic molecule featuring a heterocyclic core with substituents designed to engage the catalytic residues of endoproteases while allowing passage across cellular membranes. The hypothetical mechanism involves reversible or covalent interaction with the active site, thereby blocking proteolysis of intracellular substrates and affecting proteostasis and downstream signaling.

In speculative literature, endoproteeside is discussed as a research tool for studying the role of endoproteases in protein turnover, quality control, and inflammatory pathways. Some models suggest potential therapeutic applications for conditions driven by excessive endoprotease activity, but there is no experimental evidence, no sanctioned synthesis, and no clinical testing. Consequently, endoproteeside remains a fictional construct used to illustrate concepts in protease biology and drug design.
