| | Nortadalafil Usage And Synthesis |
| Uses | A N-desmethyl analogue of the human PDE5 inhibitor Tadalafil (T004500). A potential antiplasmodial drug. | | Biological Activity | the cgmp-specific pde5 is the major pde isozyme in the corpus cavernosum, and controls penile erection. the pde5 inhibitors used in the clinic amplify the no-ccmp pathway and enhance the normal process leading to penile erection.nortadalafil is demethyl tadalafil, which is a pde5 inhibitor currently marketed in pill form for treating erectile dysfunction under the name cialis and for the treatment of pulmonary arterial hypertension under the name adcirca. | | in vitro | tadalafil has been identified as a highly potent pde5 inhibitor (ic50 = 5 nm) with high selectivity for pde5 vs pde1-4 and pde6. it displays 85-fold greater selectivity vs pde6 than sildenafil [1]. | | in vivo | tadalafil showed profound and long-lasting blood pressure lowering activity (30 mmhg/>7 h) in the spontaneously hypertensive rat model after oral administration (5 mg/kg) [1]. | | target | PDE5 | | IC 50 | n/a for nortadalafil; 5 nm for tadalafil | | references | [1] daugan a, grondin p, ruault c, le monnier de gouville ac, coste h, linget jm, kirilovsky j, hyafil f, labaudinière r. the discovery of tadalafil: a novel and highly selective pde5 inhibitor. 2: 2,3,6,7,12,12a-hexahydropyrazino[1',2':1,6]pyrido[3,4-b]indole-1,4-dione analogues. j med chem. 2003;46(21):4533-42.
