Mark Pimentel, MD: Let’s transition to the GC-C [guanylate cyclase-C] agonists. Tony, let’s start with linaclotide, and then we’ll move on to plecanatide. And then we’ll argue about which has less diarrhea, because that’s always the argument. But start with linaclotide. Anthony J. Lembo, MD: Sure. It was the first of the 2 GC-C agonists..

Guanylate cyclase 2C, also known as guanylyl cyclase C (GC-C), intestinal guanylate cyclase, guanylate cyclase-C receptor, or the heat-stable enterotoxin receptor (hSTAR) is an enzyme that in humans is encoded by the GUCY2C gene. Guanylyl cyclase is an enzyme found in the luminal aspect of intestinal epithelium and dopamine neurons in the brain. Over the last decade, pre-clinical and clinical studies have revealed a variety of novel mechanisms relating to the visceral analgesic effects of guanylate cyclase-C (GC-C) agonists. Here we discuss the mechanisms by which GC-C agonists target the GC-C/cyclic guanosine-3’,5’-monophosphatec (GMP) pathway, resulting in visceral analgesia as ...The early GLP-1R agonist has many defects, such as multiple injections and a high incidence of adverse reactions in the digestive tract, which limits its clinical application.
