产品介绍
Linaclotide 是一种有效的选择性鸟苷酸环化酶 C 激动剂,可用于治疗便秘型肠易激综合征 (IBS-C) 和慢性便秘的研究。

产品描述

Linaclotide developed for the treatment of constipation-predominant irritable bowel syndrome (IBS-C) and chronic constipation, and is a potent and selective guanylate cyclase C agonist.

体外活性

Linaclotide acts on guanylate cyclase-C receptors on the luminal membrane to increase chloride and bicarbonate secretions into the intestine and inhibit the absorption of sodium ions, thus increasing the secretion of water into the lumen and improving defecation;?the drug is minimally absorbed into the systemic circulation[2].Linaclotide inhibits in vitro [125I]-STa binding to intestinal mucosal membranes from wt mice in a concentration-dependent manner.?In contrast, [125I]-STa binding to these membranes from GC-C null mice is significantly decreased.?After incubation in vitro in jejunal fluid for 30 min, linaclotide is completely degraded[1].

体内活性

Linaclotide significantly increases weekly spontaneous bowel movements and complete spontaneous bowel movements (CSBMs) while reducing abdominal pain in patients with chronic constipation[2].Pharmacokinetic analysis shows very low oral bioavailability (0.10%).?In intestinal secretion and transit models, linaclotide exhibits significant pharmacological effects in wt, but not in GC-C null mice: induction of increased fluid secretion into surgically ligated jejunal loops is accompanied by the secretion of elevated levels of cyclic guanosine-3',5-monophosphate and accelerated gastrointestinal transit[1].
