Phosphodiesterase-5. A phosphodiesterase inhibitor is a drug that blocks one or more of the five subtypes of the enzyme phosphodiesterase (PDE), thereby preventing the inactivation of the intracellular second messengers, cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) by the respective PDE subtype(s).
Cyclic di-GMP (also called cyclic diguanylate and c-di-GMP) is a second messenger used in signal transduction in a wide variety of bacteria. [1] Cyclic di-GMP is not known to be used by archaea , and has only been observed in eukaryotes in Dictyostelium . [ 2 ]
Cyclic guanosine monophosphate (cGMP) is a cyclic nucleotide derived from guanosine triphosphate (GTP). cGMP acts as a second messenger much like cyclic AMP.Its most likely mechanism of action is activation of intracellular protein kinases in response to the binding of membrane-impermeable peptide hormones to the external cell surface. [1]
Guanosine (symbol G or Guo) is a purine nucleoside comprising guanine attached to a ribose (ribofuranose) ring via a β-N 9-glycosidic bond.Guanosine can be phosphorylated to become guanosine monophosphate (GMP), cyclic guanosine monophosphate (cGMP), guanosine diphosphate (GDP), and guanosine triphosphate (GTP).
Adding PDE5 inhibitors to SSRI drugs (e.g. paroxetine) for the treatment of premature ejaculation could result in better ejaculatory control according to recent studies. [11] Possible mechanism is based on nitric oxide (NO)/cGMP transduction system as a central and peripheral mediator of inhibitory non-adrenergic, non-cholinergic nitrergic ...
Chemical structure of sildenafil (Viagra), the prototypical PDE5 inhibitor. A phosphodiesterase type 5 inhibitor (PDE5 inhibitor) is a vasodilating drug that works by blocking the degradative action of cGMP-specific phosphodiesterase type 5 (PDE5) on cyclic GMP in the smooth muscle cells lining the blood vessels supplying various tissues.
PDE5 inhibitor drugs are effective in men regardless of why they have erectile dysfunction — including vascular disease, nerve problems, and even psychological causes. [citation needed] PDE5-inhibiting drugs can cause a number of side-effects, including headache, lightheadedness, dizziness, flushing, nasal congestion, and changes in vision.
