In Pursuit of an Allosteric Human Tropomyosin Kinase A (hTrkA) Inhibitor for Chronic Pain.

ABSTRACT: Human β-nerve growth factor (β-NGF) and its associated receptor, human tropomyosin receptor kinase A (hTrkA), have been demonstrated to be key factors in the perception of pain. However, efficacious small molecule therapies targeting the intracellularly located hTrkA kinase have not been explored thoroughly for pain management. Herein, we report the pharmacological properties of a selective hTrkA allosteric inhibitor, 1. 1 was shown to be active against the full length hTrkA, showing preferential binding for the inactive kinase, and was confirmed through the X-ray of hTrkA···1 bound complex. 1 was also found to inhibit β-NGF induced neurite outgrowth in rat PC12 cells. Daily oral administration of 1 improved the joint co
