Enfuvirtide (Synthetic Peptide Hormone Analogue)
Enfuvirtide is a synthetic polypeptide that functions as a structural analogue of natural peptide hormones, though its primary use is as an antiviral HIV entry inhibitor. Since it is not used primarily as a hormone, it may not fall under this heading; however, if imported as a hormone analogue for research or intermediate use, it could be classified here.
