Several randomized controlled trials (RCTs) were conducted for evaluating its efficacy and safety. Methods: The PubMed, EMBASE, and …

While STING agonists have proven to be effective preclinically as anti-tumor agents, these promising results have yet to be translated in the clinic. A STING agonist antibody–drug conjugate (ADC) could overcome current limitations by improving tumor accessibility, allowing for systemic administration as well as tumor-localized activation of …

Occasionally one may find that the PD effect influences the PK and vice-versa. For example, LXR agonists are known to have an agonistic effect on PXR due to very high homology between the two receptors, and consequently result in an induction of the CYP3A4 enzyme (Shenoy et al., 2004).Mar 13, 2015 · Linaclotide is a potent agonist of the guanylyl cyclase C (GC-C) receptor, which is located on the luminal surface of intestinal epithelial cells (ICE) throughout the gut mucosa (Li and Goy 1993).

GC-C agonists. The key difference between UG and ST peptide is the presence of 2 charged aspartate amino acids within the N-terminus of UG (Figure 1); these as-partates regulate binding affinity of UG to GC-C in a pH-dependent manner.9 The 2 prototype exogenous GC-C re-ceptor agonists are linaclotide and plecanatide (Figure 1), which are

Toxin interaction with the extracellular domain activates the cytoplasmic catalytic domain of GC-C, inducing accumula-An agonist is a ligand that can stimulate (agonize) the GPCR to activate intracellular signaling and trigger a biological response. In contrast, an antagonist is one such ligand that can inhibit (antagonize) the action of an agonist, either natural or synthetic, to suppress the signaling and biological response.The role of GCC as a tumor suppressor and the universal loss of its hormones in transformation suggest a paradigm in which colorectal cancer is a disease of paracrine hormone insufficiency. Indeed, GCC signaling reverses the tumorigenic phenotype of human colon cancer cells by regulating proliferation and metabolism. These data …Unimolecular dual agonists for the glucagon-like peptide 1 receptor (GLP1R) and glucagon receptor (GCGR) are emerging as a potential new class of important therapeutics in type 2 diabetes (T2D).

The invention provides low-dose formulations of guanylate cyclase-C (“GCC”) agonist peptides and methods for their use. The formulations of the invention can be administered either alone or in combination with one or more additional therapeutic agents, preferably an inhibitor of cGMP-dependent phosphodiesterase or a laxative.The transmembrane receptor guanylyl cyclase‐C (GC ‐C), expressed on enterocytes along the intestine, is the molecular target of the GC ‐C agonist peptide linaclotide, an FDA ‐approved drug for treatment of adult patients with Irritable Bowel Syndrome with Constipation and Chronic Idiopathic Constipation. Guanylate cyclase-C agonists are a class of medications used to treat constipation associated with irritable bowel syndrome (IBS) and chronic constipation of unknown cause (idiopathic constipation) in adults.
