Activité biologique

Description Sildenafil Citrate, un inhibiteur sélectif de la phosphodiestérase de type 5 (PDE5) spécifique de la guanosine monophosphate cyclique (cGMP), est un traitement bien toléré et très efficace contre la dysfonction érectile.

In vitro Sildenafil citrate is a potent PDE type 5 reversible and selective inhibitor that blocks cGMP hydrolysis effectively (Ki ∼3 nM). Sildenafil exhibited high affinity for PDE type 5 and type 6 with inhibition constants (Ki) of ∼3.5 and 33 nM, respectively. Sildenafil enhances sodium nitroprusside- or transmural electrical stimulation-induced relaxation of precontracted corpus cavernosum muscle strips in organ baths, suggesting that sildenafil augments the activity of NO-mediated relaxation. Sildenafil citrate increases intracellular cGMP concentrations in cultured smooth muscle cells treated with sodium nitroprusside and in rabbit corpus cavernosum in vitro. Sildenafil is metabolized in the liver by cytochrome P450 and is converted into an active metabolite with characteristics similar to the parent compound.
In vivo Sildenafil citrate enhances erectile function following pelvic nerve stimulation in anesthetized dogs as measured by increased intracavernosal pressure. Sildenafil citrate significantly reverses impaired carbachol-stimulated relaxation and inhibits superoxide formation by cavernosal tissue from hypercholesterolaemic rabbits. Sildenafil improves erectile function in a time- and dose-dependent fashion with maximization of erectile function recovery occurring with daily 20 mg/kg at the 28-day time point in Sprague-Dawley rats. Sildenafil use results in smooth muscle-collagen ratio protection and CD31 and eNOS expression preservation in Sprague-Dawley rats. Sildenafil reduces apoptotic indices significantly compared with control, and increases phosphorylation of akt and eNOS in Sprague-Dawley rats.

Validation du produit par le client

<p>T24 cells were treated with vehicle, SIL (2 uM), DOX (200 nM) as indicated. Cells were isolated 6 and 12 hours after exposure, and the phosphorylation of γH2AX was determined, with the fold increase in phosphorylation shown.</p>

BT549 and HOSS1 cells in 96 well plates were treated with celecoxib (CEL 5.0 uM) and/or sildenafil (SIL, 2.0 uM). Six h after treatment cells were fixed to the plate and immunohistochemistry performed to determine the plasma membrane levels of CD95. The upper images obtained using the Hermes Wiscan imaging system is representative of the data. The intensity of CD95 immunostaining was determined using the Wisoft data analysis package (n = 3 +/- SEM). * p < 0.05 value greater than celecoxib treatment alone.

ADOR lung cancer cells (a July 2015 PDX model) were transfected with an empty vector plasmid or plasmids to express GRP78 and HSP27 together. Twenty-four hours after transfection cells were treated with vehicle control or with OSU-03012 (2.0mM) sildenafil (2mM) for 6 h after which cells were fixed in place and permeabilized using 0.5% Triton X100. Immuno-fluorescence was performed to detect the expression levels of Calnexin; glucosidase I; and glucosidase IIa at 10 magnification using a Hermes WiScan system.
