5050 9-Hydroxyphenanthrene This compound belongs to the family of Phenanthrenes and Derivatives. These are polycyclic compounds containing a phenanthrene moiety, which is a tricyclic aromatic compound with three non-linearly fused benzene. 484-17-3 10229 C14H10O 139-143 C 9-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. (A15462) 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. (A15463) No indication of carcinogenicity to humans (not listed by IARC). 2014-10-14T21:20:37Z 2026-04-03T01:22:59Z C11430 28820 true OC1=CC2=CC=CC=C2C2=CC=CC=C12 C14H10O InChI=1S/C14H10O/c15-14-9-10-5-1-2-6-11(10)12-7-3-4-8-13(12)14/h1-9,15H DZKIUEHLEXLYKM-UHFFFAOYSA-N 194.2286 194.073164942 Exogenous Solid HMDB59801 9812 CHEM003945 DTXSID9047592 phenanthren-9-ol
