Biological target:
IC87201, an inhibitor of PSD95-nNOS protein-protein interactions, suppresses NMDAR-dependent NO and cGMP formation.
In vitro activity:
The resulting compound, IC87201, 2-[(1H-benzotriazol-5-ylamino)-methyl]-4,6-dichloro-phenol (Figure 1A), showed dose-dependent inhibition of nNOS–PSD95 binding (Figure 1B) with an IC50 of 31 µM (95% confidence interval 25–38 µM, n= 5).

In vivo activity:
IC87201 and ZL006, but not ZL007, suppressed phase 2 of formalin-evoked pain behavior and decreased the number of formalin-induced Fos-like immunoreactive cells in spinal dorsal horn regions associated with nociceptive processing.
