PDE5 inhibitors: Video, Anatomy, Definition Function

Since PDE5 hydrolyzes cyclic guanosine monophosphate (cGMP) in the cardiopulmonary vasculature, researchers aimed to establish a new anti-anginal agent using PDE5 Therefore, PDE5 selective inhibitors could be potent anticancer drugs with a novel mechanism of action (Figure 2). Accordingly, sildenafil and vardenafil induced caspase dependent apoptosis and antiproliferation in B-cell chronic lymphatic leukemia ( Sarfati et al, 2024 ; Zhu et al, 2024 ). Among all PDEs, PDE5, which is influenced by sildenafil and other inhibitors of clinical use, has been widely investigated. 3 Three PDE5 isoforms have been described, identified as PDE5 A1, A2, and A3. 5 PDE5 A1 and A2 isoforms are expressed in several tissues, including brain, lung, heart, kidney, bladder, prostate, urethra, penis, uterus, and skeletal muscle. pde5 inhibitors moa The catalytic site of PDE5 normally degrades cGMP, and PDE5 inhibitors such as sildenafil potentiate endogenous increases in cGMP by inhibiting its breakdown at the catalytic site. Phosphorylation of PDE5 increases its enzymatic activity as well as the affinity of its allosteric (noncatalytic/GAF domains) sites for cGMP. Introduction. Phosphodiesterase type 5 inhibitors (PDE5i) are powerful strong vasoactive drugs widely used to treat erectile dysfunction (ED) by the specific inhibition of PDE5 activity. 3,5 -Cyclic nucleotide phosphodiesterases (PDEs) are ubiquitous catalytic enzymes that cleave the phosphodiester bonds in cyclic adenosine or guanosine monophosphate (cAMP and cGMP) to yield 5 -cyclic

These drugs are available in most countries of the world. Other PDE5 inhibitors such as udenafil, mirodenafil and lodenafil are also available in some countries (Hatzimouratidis et al, 2024). The structural differences between these PDE5 inhibitors are small, but they have different pharmacokinetic (Table 1) and dynamic properties (Table 2 PDE5 inhibitors cause pulmonary vasodilation and penile smooth muscle relaxation, and are used for pulmonary hypertension and erectile dysfunction.
