SUN13837
SUN13837 is an orally active, blood-brain barrier permeable FGFR modulator and neuroprotective agent. SUN13837 mimics the activity of basic fibroblast growth factor, stimulates intracellular tyrosine phosphorylation of FGFR and signal transduction in neuronal cells, induces neurite outgrowth, and inhibits glutamate-induced neuronal death. SUN13837 can be used in research related to acute cervical spinal cord injury and severe spinal cord injury.

Biological Activity
SUN13837 (10 μM; 24 h pre-incubation before glutamate exposure) exhibits 100% neuroprotective activity against glutamate-induced cell death in rat embryonic cerebral cortex and hippocampal neurons[2].
SUN13837 (10 μM; 30 min pre-incubation) inactivates CYP3A4 in a mechanism-based manner in liver microsomes, with residual activity of 60%[2].
SUN13837 (10 μM; 120 min) is a substrate of P-gp, with an efflux ratio of 6.3 in Caco-2 cell monolayers[2].
SUN13837 (100 μM; 60 min) undergoes hydrolysis by liver microsomes at a rate of 7.2 pmol/min/mg protein[2].
SUN13837 (0.3-3 μM) potently induces axonal growth in primary hippocampal neurons from E18 Wistar rats. The effect produced by 3 μM SUN13837 is comparable to that of 3 ng/mL bFGF, and significant increases in axon length are observed at concentrations of 0.3 μM and 3 μM[3].
SUN13837 (0.1-1 μM) protects primary hippocampal neurons from E18 Wistar rats against glutamate-induced cell death by activating FGFR-1, with significant neuroprotective effects observed at concentrations of 0.1 μM, 0.3 μM and 1 μM[3].
SUN13837 (0.3-3 μM; 40 minutes) activates intracellular tyrosine phosphorylation via human FGFR-1 in transfected L6 rat skeletal muscle cells, with significant elevations observed at concentrations of 0.3 μM, 1 μM and 3 μM[3].
SUN13837 (0.1-30 μM; 22-23 h) does not induce proliferation in SW1353 chondrosarcoma cells or Swiss 3T3 mouse embryonic fibroblasts, even at concentrations as high as 30 μM[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:Swiss 3T3 mouse embryo fibroblast cells
-
Concentration:10 μM
-
Incubation Time:16 h
-
Result:Had no significant effect on cyclin D1 expression.
Had no significant effect on p27(kip1) expression.
Contrasted with bFGF, which increased cyclin D1 expression by 4.6-fold and decreased p27(kip1) expression to 5% of control levels.
Systemic administration of SUN13837 (0.3-1 mg/kg; i.v.; daily; 10 days) starting up to 12 hours post-spinal cord injury significantly enhances hind limb motor function recovery (BBB score >12 at 8 weeks) and axon regeneration in rats without adverse events[3].

Animal Model:Slc: SD (female, 180-250 g, T9 spinal cord contusion injury model)[3]
-
Dosage:0.3 mg/kg (first dose 90 mins post-injury); 1 mg/kg (first dose 90 mins post-injury); 1 mg/kg (first dose 12 hours post-injury)
-
Administration:i.v.; daily; 10 days
-
Result:Showed significantly enhanced hind limb motor function from 2 weeks post-injury onward, reaching a BBB score >12 at 8 weeks (p = 0.017), compared to vehicle group's score of 8.
Shortened MEP latency significantly (p = 0.0146) and increased MEP amplitude relative to vehicle.
Had higher BBB scores than vehicle at all time points, but the difference did not reach statistical significance (p = 0.118).
Showed significantly enhanced motor function recovery from 5 weeks post-injury onward, with a significant difference at 8 weeks (p = 0.025).
Increased 5-HT-positive area 4 mm caudal to the contusion epicenter significantly (p = 0.0043 for 90-minute group, p = 0.027 for 12-hour group) relative to vehicle.
Induced extensive caudal extension of corticospinal tract axons through the contusion site into lumbo-sacral spinal segments, whereas axon extension was limited to distal stumps in vehicle-treated rats.
