KB-5492 anhydrous is a potent and selective inhibitor of sigma receptor, inhibits specific [3H]1,3-di(2-tolyl)guanidine (DTG) binding to the sigma receptor with an IC50 of 3.15 μM. KB-5492 anhydrous is an anti-ulcer agent[1][2].
KB-5492 (0.001-100 μM) inhibits specific [3H]DTG binding in a concentration-dependent manner[1].KB-5492 (0.1-1 mM) significantly and concentration-dependently prevents the ethanol- and acidified aspirin-induced increases in 51Cr release from gastric epithelial cells[2].
KB-5492 (200 mg/kg; p.o.) prevents macroscopic lesions in the gastric mucosa[2]. Animal Model: Male Sprague-Dawley rats weighing 210-240 g are induced gastric mucosal damage[2]
