What is Lafutidine?

Description

Lafutidine was launched in Japan for the treatment of gastritis, reflux oesophagitis and peptic ulcers. It can be prepared in eight steps from 4-(2-tetrahydropyranyloxy)-2(Z)-butenl- ol. Lafutidine is a potent and longer-acting H₂ antagonist compared to other marketed compounds of its class such as cimetidine and famotidine. In contrast to other commercially available H₂ antagonists, lafutidine also exerts a gastroprotective action probably via capsaicin-sensitive afferent nerves. It was clinically effective in the treatment of nonsteroidal antiinflammatory drug-induced ulcer in patients refractory to existing antiulcer agents.

Description

Lafutidine is a histamine H₂ receptor antagonist with gastroprotective activity. It inhibits histamine-induced cAMP production in CHO cells expressing human histamine H₂ receptors when used at a concentration of 10 nM. Intragastric administration of lafutidine (3, 10, and 30 mg/kg) reduces hemorrhagic esophageal lesion size and gastric acid secretion in a rat model of pyloric ligation-induced reflux esophagitis. It prevents 5-fluorouracil-induced intestinal mucositis, diarrhea, and body weight loss in wild-type, but not Trpv1^-/- or sensory deafferented, mice when administered at doses ranging from 3 to 30 mg/kg. Lafutidine (10 mg/kg) also reduces indomethacin-induced antral ulcer size in wild-type, but not chemically-deafferented, rats.

The Uses of Lafutidine

(Z)-2-((Furan-2-ylmethyl)sulfinyl)-n-(4-((3-(piperidin-1-ylmethyl)pyridin-2-yl)oxy)but-2-en-1-yl)acetamide is a Histaminic H2 receptor antagonists in ulcer disease. Also, it is a model compound used to investigate the binding mechanism between antiulcer drugs and human serum albumin (HSA).
