| Hazard Information | Back Directory | [Description]
MY-5445 is a selective inhibitor of the cyclic GMP (cGMP) phosphodiesterase, PDE5, with a Ki value of 1.3 μM. It inhibits calcium- and cAMP-selective PDEs with Ki values of >1,000 and 915 μM, respectively. MY-5445 has been shown to relax intact strips of rat aorta with an EC50 value of 4 μM. | [Uses]
Selective inhibitor of cGMP-specific phosphodiesterase (PDE V, IC50=0.6μM). | [Definition]
ChEBI: N-(3-chlorophenyl)-4-phenyl-1-phthalazinamine is a ring assembly and a member of pyridazines. | [Biological Activity]
Specific inhibitor of cyclic GMP phosphodiesterase, selective for PDE5 (IC 50 = 0.5 μ M). | [in vivo]
MY-5445 (0.5-3 mg/kg; i.p.; twice a day; for 15 days) produces a significant relief of mechanical hypersensitivity[3].
| Animal Model: | C57BL/6J male mice[3] | | Dosage: | 0.5 mg/kg, 3 mg/kg | | Administration: | Intraperitoneal injection, twice a day, for 15 days | | Result: | Alleviated the cuff-induced allodynia. |
