2-GUANIDINOBENZIMIDAZOLE Chemical Properties,Usage,Production

Description

2GBI (5418-95-1) is a selective and state-dependent blocker of voltage-gated proton channels (Hv1).1?2GBI blocks the channel by binding to the voltage-sensing domain from its intracellular side.2,3? Inhibition of Hv1 is a potentially new target of intervention in various pathophysiological processes including inflammatory, cancer, bone resorption and neurodegenerative disease.4

Chemical Properties

BROWN-PURPLE FINE CRYSTALLINE POWDER

Uses

N-1H-Benzimidazol-2-ylguanidine is used as a reagent in the synthesis of novel fused pyrimidines and imidazoles as potential analgesics.

Definition

ChEBI: 2-Benzimidazolylguanidine is an aminoimidazole.
