(R)-Igmesine hydrochloride
Based on 1 Customer Validation
(+)-Igmesine hydrochloride (JO1784) is an orally active and selective σ1 receptor ligand with an IC50 of 39 nM. (+)-Igmesine hydrochloride binds σ1 receptors to activate G-proteins and modulate Ca2+ uptake. (+)-Igmesine (hydrochloride) attenuates ischaemia-induced nitric oxide synthase activity and hyperactivity. (+)-Igmesine hydrochloride can be used for the research of duodenal ulcers, gastric ulcers, and cerebral ischaemia.
For research use only. We do not sell to patients.

(+)-Igmesine (1 nM-10 μM; 52 h) hydrochloride potently suppresses Phytohemagglutinin-P (HY-N7038A)-, Concanavalin A (HY-P2149)-, and pokeweed mitogen-stimulated proliferation of rat lymphocytes with reductions in tritiated thymidine uptake[4].
(+)-Igmesine (1 nM-10 μM; 40 min-52 h) hydrochloride exhibits dose-dependent suppression of rat neutrophil phagocytosis and mitogen-stimulated rat lymphocyte proliferation[4].

Cell Line:rat lymphocytes
-
Concentration:1 nM; 100 nM; 10 μM
-
Incubation Time:52 h
-
Result:Potently suppressed Phytohemagglutinin-P -, Concanavalin A-, and pokeweed mitogen-stimulated proliferation of rat lymphocytes with reductions in tritiated thymidine uptake.
(+)-Igmesine (p.o.; single dose) hydrochloride weakly protects rats from multiple models of gastric mucosal damage, with ED50 values ranging from 25.2 to 55.4 mg/kg p.o[1].
(+)-Igmesine (1-30 mg/kg; i.d.; single dose) hydrochloride does not exhibit gastric antisecretory activity in pylorus-ligated rats[1].
(+)-Igmesine (0.25-2 mg/kg; i.v.; single bolus) hydrochloride dose-dependently stimulates duodenal bicarbonate secretion in anesthetized rat[1].
(+)-Igmesine (25-100 mg/kg; p.o.; at 1, 24, and 48 hours post-surgery) hydrochloride provides statistically significant neuroprotection against ischaemia-induced hippocampal CA1 neuronal death in gerbils[2].
(+)-Igmesine (100 mg/kg; i.p.; at 30 minutes, 6, 24, and 48 hours post-surgery) hydrochloride significantly attenuates ischaemia-induced hyperactivity and increases in NO synthase activity in the hippocampus and brain stem of gerbils[2].

Animal Model:Sprague-Dawley (male, 180-220 g, cysteamine-induced duodenal ulcer)[1]
-
Dosage:1 mg/kg; 3 mg/kg; 10 mg/kg
-
Administration:p.o.; single dose
-
Result:Induced a dose-related decrease in ulcer index, with an ED50 of 4.14 mg/kg p.o.
Reduced the mean ulcer index from 33.2 mm2 to 9.7 mm2, a 71% reduction, at 10 mg/kg p.o.
Lost protective effect when pre-treated with haloperidol (1 or 3 mg/kg s.c.), BMY 14,802 (10 mg/kg p.o.), or devazepide (30 mg/kg p.o.).
-
Animal Model:Sprague-Dawley (male, 250-400 g, pylorus-ligated Shay rat preparation)[1]
-
Dosage:1 mg/kg; 3 mg/kg; 10 mg/kg; 30 mg/kg
-
Administration:i.d.; single dose
-
Result:Did not significantly modify free or total gastric acid concentration or output at any tested dose compared to control rats.
-
Animal Model:Sprague-Dawley (male, 250-400 g, anesthetized in situ duodenal perfusion model)[1]
-
Dosage:0.25 mg/kg; 0.5 mg/kg; 1 mg/kg; 2 mg/kg
-
Administration:i.v.; single bolus
-
Result:Induced a dose-related increase in duodenal bicarbonate output, with a threshold dose of 0.25 mg/kg i.v. and maximal response at 1 mg/kg i.v.
Increased bicarbonate output from a basal 7.60 μEq·cm-1·h-1 to a plateau of 14.8 μEq·cm-1·h-1 (P < 0.001) that lasted 2 hours at 1 mg/kg i.v.
Did not further increase secretion when dose was doubled to 2 mg/kg i.v.
Lost stimulatory effect when pre-treated with haloperidol (0.50 mg/kg i.v.), BMY 14,802 (5 mg/kg i.v.), hexamethonium (1 mg/kg i.v.), tetrodotoxin (5 μg/kg i.v.), devazepide (0.50 mg/kg i.v.), or bilateral truncal vagotomy.
Showed no significant change in stimulatory effect with atropine (0.25 mg/kg i.v.), SCH 23,390 (0.50 mg/kg i.v.), sulpiride (1 mg/kg i.v.), prazosin (0.50 mg/kg i.v.), yohimbine (2 mg/kg i.v.), naloxone (0.20 mg/kg i.v.), indomethacin (0.25 mg/kg i.v.), or intracerebroventricular devazepide (17 μg/rat).
