A-331440 is a potent and selective histamine H3 receptor antagonist that regulates neurotransmitter release by inhibiting presynaptic H3 receptors. In preclinical studies involving mice on a high-fat diet, A-331440 demonstrated dose-dependent effects on weight reduction and fat loss. At 5 mg/kg, it effectively decreased body weight comparable to dexfenfluramine, while at 15 mg/kg, it significantly reduced body fat and improved insulin tolerance, similar to mice on a low-fat diet. These findings suggest that A-331440 holds promise as an antiobesity agent by modulating histaminergic pathways involved in food intake and metabolic regulation.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
