Description

General description

A cell-permeable chlorostyrylquinolinylbutylamino compound that was shown to competitively bind to glial cell line-derived neurotrophic factor (GDNF) family receptor-α1 (GFRα1) and act as an agonist (IC₅₀ = 10.4 µM for ¹²⁵I-GDNF binding in Neuro-2A cells) and induce autophosphorylation of RET protein. Elicits neurite outgrowth of Neuro-2A cells in a dose-dependent manner. However, some of the recent studies have questioned its agonist nature and have suggested that it acts as a positive modulator of ligand-Induced GFRα/RET signaling and prolongs the GDNF-induced RET phosphorylation. Shown to be effective in treating small fiber neuropathy caused by non-myelinating Schwann cell dysfunction in diabetic murine models leading to improved thermononiception. Does not appear to be toxic up to ~100 µM.
