What is Tirzepatide (WLZ4518)?

Tirzepatide is a synthetic 39-amino-acid peptide acting as a dual agonist at the glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. The sequence is based on the native GIP backbone rather than GLP-1, with a fatty-acid moiety supporting albumin binding. It is the reference compound against which newer multi-incretin agonists are compared in the literature.

What the published research on Tirzepatide covers

Identity. Synthetic peptide engineered from the native GIP sequence, with agonist activity at both the GIP and GLP-1 receptors. Development code LY3298176; marketed as Mounjaro and Zepbound.

Unlike most of this catalogue, tirzepatide is a licensed medicine with phase 3 data. The SURMOUNT programme is the reference set, and a later head-to-head trial compared it against semaglutide.
