    Product Description

    Linaclotide-d4 is intended for use as an internal standard for the quantification of linaclotide (Item No. 24085) by GC- or LC-MS. Linaclotide is a peptide agonist of the guanylate cyclase C receptor (Ki = 16.4 nM in a radioligand binding assay using mouse intestinal mucosa).1 Luminal exposure to 5 μg of linaclotide stimulates fluid secretion and cGMP concentration in jejunal loops isolated from wild-type mice but not guanylate cyclase C receptor-null mice. Linaclotide (100 μg/kg) increases intestinal transit rate in wild-type mice. It also reduces the number of phosphorylated ERK-positive dorsal horn neurons in the thoracolumbar spinal cord, a marker of nociceptive signaling, following noxious colorectal distension and mechanical hypersensitivity in a mouse model of TNBS-induced colitis.2 Formulations containing linaclotide have been used for the treatment of constipation and pain associated with irritable bowel syndrome.
