Metabolite Identification
Common Name9-Hydroxyphenanthrene
Description9-Hydroxyphenanthrene, also known as 9-phenanthrol, belongs to the class of organic compounds known as phenanthrols. Phenanthrols are compounds containing a phenanthrene (or its hydrogenated derivative) to which a hydroxyl group is attached. 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. 9-Hydroxyphenanthrene is an extremely weak basic (essentially neutral) compound (based on its pKa). 9-Hydroxyphenanthrene is a potentially toxic compound. These are polycyclic compounds containing a phenanthrene moiety, which is a tricyclic aromatic compound with three non-linearly fused benzene. 9-Hydroxyphenanthrene 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-Hydroxyphenanthrene modulates a variety of physiological processes through TRPM4 current inhibition. 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. The most specific inhibitor of TRPM4 channels currently available is 9-phenanthrol, which abolishes arrhythmias induced by hypoxia and reoxygenation in the mouse ventricle.
