RET agonist BT44

RET agonist BT44 is a novel, specific RET agonist, promotes RET phosphorylation and selectively activates downstream cascades in the cells expressing GFL receptors.BT44 has no effect on TrkA and TrkB receptors; In GFRα1/RET expressing cells, 10–50 µM of BT44 increased the activity of luciferase reporter by approximately two fold (P<0.0001).BT44 dose-dependently stimulated neurite outgrowth from DRG sensory neurons and its efficacy was comparable to that of ARTN.BT44 alleviated mechanical hypersensitivity in surgery- and diabetes-induced rat models of neuropathic pain.
