Toxicity Profile
Route of ExposureNot Available
Mechanism of Toxicity9-phenanthrol is a recently identified inhibitor of the transient receptor potential melastatin (TRPM) 4 channel, a Ca(2+) -activated non-selective cation channel whose mechanism of action remains to be determined. 9-phenanthrol modulates a variety of physiological processes through TRPM4 current inhibition. 9-Phenanthrol modulates smooth muscle contraction in bladder and cerebral arteries, affects spontaneous activity in neurons and in the heart, and reduces lipopolysaccharide-induced cell death. 9-phenanthrol exerts cardioprotective effects against ischaemia-reperfusion injuries and reduces ischaemic stroke injuries. (1) The most specific inhibitor of TRPM4 channels currently available is 9-phenanthrol, which abolishes arrhythmias induced by hypoxia and reoxygenation in the mouse ventricle. TRPM4 has been linked to diverse physiological functions such as protection against Ca2+ overload, regulating the levels of intracellular ATP and reactive oxygen species, and cell death. TRPM4 in neurons contributes toward inflammation-induced neurodegeneration by mediating cell death, which corresponds to the cardioprotective effect of 9-phenanthrol. Damage induced by ischemia/reperfusion (I/R) was caused by TPRM4-dependent cell death and that 9-phenanthorol induces cardioprotection by blocking this pathway. (2)
