TrkA inhibitor compound 23(TrkA-IN-23)

TrkA-IN-23 is a highly potent, subtype selective, peripherally restricted, allosteric TrkA inhibitor with IC50 of 10 nM, 180-fold selective over TrkB and 70-fold selective over TrkC in cell based assays; exhibits exquisite TrkA selectivity with >95% inhibition of TrkA and <15% inhibition in 392 biochemical kinase assays; also exhibits 18-fold selectivity for the non-activated TrkA construct (TrkA non-activated enzyme IC50=4nM, TrkA activated enzyme IC50=74 nM); inhibits NGF induced phosphorylated ERK formation in native adult rat DRGs with IC50 of 57 nM, abolishes sensitization to capsaicin administration to NGFsensitised skin in vivo in anaesthetised rats; demonstrates efefctivity in UVIH model of inflammatory pain in rats.
