KCL-286
Based on 1 Customer Validation
KCL-286 (C286) is an orally active and brain-penetrant retinoic acid receptor (RAR) β2 agonist (EC50 = 1.9 nM). KCL-286 targets RARβ2 with good selectivity over RAR α (EC50 = 26 nM) and RAR γ (EC50 = 11 nM). KCL-286 activates RARβ2 in the injured neurons. KCL-286 induces axonal regeneration of both spinal and sensory nerves through the inhibitory environment of the CNS, modulates neuroinflammation and extracellular matrix molecules. KCL-286 can modulate the expression of CSPGs by neuronal secretion of decorin which promotes myelination and aids axonal growth. KCL-286 can be studied in research for area such as spinal cord injury and traumatic nerve injury.

Animal Model:Non-injured or avulsed male Sprague-Dawley rats[2]
-
Dosage:3 mg/kg, every other days for 4 weeks
-
Administration:Oral gavage (p.o.)
-
Result:Resulted in 82 genes presenting a return to their basal level and 99 genes being strongly upregulated in injured model.
Resulted in 58 genes returning to their basal level after being significantly downregulated under injured conditions.
Significantly modified genes associated with ECM, paths within this signaling complex were both upregulated (those pertaining to the modulation of the cholinergic system, ion transport, and ion channels) or downregulated by the drug after injury.
Highly upregulated the ligand-gated ion channel.
Regulated the G-protein coupled receptor signaling cascades and G-protein coupled receptor protein pathways and chemokine signalling.
Upregulated RARβ in the cell bodies and axons of all neuron subtypes.
