Biological Activity for Diminazene aceturate
Diminazene aceturate is an ASIC blocker (IC50 values are 202, ~320, ~320 and 864 nM for ASIC1b, ASIC1a, ASIC3 and ASIC2a, respectively). Exhibits no activity in ENaC channels expressed in oocytes. Accelerates desensitization of ASIC currents in hippocampal neurons. Inhibits mesotrypsin (Ki = 3.6±0.3 μM). Displays in vitro and in vivo anti-inflammatory effects in mice. Antihyperalgesic.

Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.
