NO-794 is a histamine H₂ receptor antagonist. NO-794 inhibits gastric acid secretion in pylorus-ligated rats. NO-794 can be used for the research of peptic ulcers^[1].

IC₅₀ & Target^[1]

H₂ Receptor

All Histamine Receptor Isoforms :

In Vitro

NO-794 (0-30 min) is a potent, time-dependent and irreversible histamine H₂ receptor antagonist acting on dispersed guinea pig gastric mucosal cells, with a -log K_B value of 8.4^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

NO-794 (0.5-2 mg/kg; intradermal injection; single administration) potently inhibits gastric acid secretion in pylorus-ligated rats, with an ED₅₀ of 0.9 mg/kg^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

Wistar (male, 180-210 g, pylorus-ligated model)^[1]
Dosage:

0.5 mg/kg; 1.0 mg/kg; 2 mg/kg
Administration:

i.d.; single dose
Result:

Reduced gastric acid output compared to controls at 0.5 mg/kg.
Significantly reduced gastric acid output by greater margins at 1.0 mg/kg and 2.0 mg/kg.
Achieved an ED50 value of 0.9 mg/kg for reduction of gastric acid secretion.
Demonstrated approximately 14 times more potency than ranitidine.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
