Background

PD123319 is a non-peptide inhibitor of angiotensin II receptor with IC50 value of 34nM [1].

Angiotensin II play roles in a variety of physiological functions. Among these, the most prominent is vascular contraction. Unlike previous drugs act as inhibitors of the formation of Ang II or ACE, PD123319 is an antagonist of angiotensin II receptor. PD123319 shows inhibition potency in both rat adrenal and brain binding assay with IC50 values of 34nM and 210nM, respectively. It is found to prevent Ang II from binding the bovine zona glomerulosa microsomal preparation with IC50 value of 6.9nM in the binding assay using microsome. In addition, it is reported that administration of PD123319 can suppress the generation of cyclic guanosine monophosphate and increase the production of prostaglandin E2. Besides that, administration of PD-123319 does not infiuence the effect of Ang II on protein tyrosine phosphorylation or thymidine incorporation [1, 2 and 3].

Protocol

Cell experiment [1]:
Cell lines	Human mesenchymal stem cells
Preparation method	The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.
Reacting condition	10 μM for 15 days
Applications	PD123319 suppressed osteogenic differentiation of human mesenchymal stem cells through inhibition of extracellular signal-regulated kinase signaling.
Animal experiment [2]:
Animal models	Rats model
Dosage form	0.5 or 2 mg/kg/day; subcutaneous injection for 6, 10 days
Applications	PD123319 attenuated hyperoxia-induced lung and heart injury at a low dose in newborn rats.
Other notes	Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
