PD169316, a specific p38 MAPK inhibitor, blocks signal transduction mediated by both TGF-β and Activin A, but not bone morphogenetic protein (BMP) 4. Suppression on TGF-β signaling in a dose-dependent manner may then reduce Smad2 and Smad3 phosphorylation, block nuclear translocation and increase the expression of TGF-β target gene. [1]
In vitro: It was reported that pretreatment of CaOV3 cells with 10 M PD169316 caused a significant decrease in Smad2 and Smad3 phosphorylation which was mediated by TGF-β. The inhibitory effect of PD 169316 was proved to act in a dose-dependent manner. Study also demonstrated that PD169316 at 5 M or higher dose directly suppressed TGF-β signaling activity. [1]
In vivo: Based on an amyloid β (Aβ) rat model of Alzheimer's disease, the effect of PD 169316 on apoptosis induced by amyloid beta was examined. It was demonstrated that caspase-3 and Bax/Bcl-2 ratio, two marks of apoptosis, were significantly decreased in the rats pre-treated with PD169316 intracerebroventricularly. This study suggested the potential neuroprotective role of PD 169316 against the neuronal toxicity induced by Aβ. [2]
Clinical trial: So far, no clinical trial has been conducted.
