A 1899 is a potent K2P3.1 (TASK-1) and K2P9.1 (TASK-3) channel blocker (IC50 values are 7 nM and 70 nM for human TASK-1 and TASK-3 expressed in CHO cells, respectively). Displays >12.5-fold selectivity for TASK-1 and TASK-3 over other K+ channels (IC50 = 0.9 μM for K2P18.1/TRESK and >2 μM for all other channels tested). Binds within open channel pore.
A 1899 is also offered as part of the Tocriscreen 2.0 Max. Find out more about compound libraries available from Tocris.

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.
