Biological target:
PYN90774 is a cell-permeable analog of the PKC-activating second messenger DAG. It activates PKC in platelets, resulting in the phosphorylation of a 40 kDa protein. PYN90774 is metabolized to its corresponding phosphatidic acid (1-oleoyl-2-acetyl-3-phosphoglycerol), most likely through the action of a diglycerol kinase.
In vitro activity:
PYN90774 was studied in ascites tumor cells. PYN90774treatment led to transient increases in inositol 1,4-bis- and inositol 1,4,5-trisphosphate liberation with peaks at 30 minutes, followed by sustained inositol phosphate accumulation at 30 minutes. Phosphatidylinositol 4-phosphate and phosphatidylinositol 4,5-bisphosphate showed transient activity profiles, while PtdIns exhibited sustained high activity levels at 30 minutes after PYN90774treatment. These findings suggest that PYN90774affects phosphoinositide metabolism by modulating PLC and phosphoinositide kinase activities.

In vivo activity:
Patients with essential hypertension exhibited increased TRPC3 and TRPC5. PYN90774-induced calcium influx was heightened in these patients and could be mitigated by TRPC3 and TRPC5 knockdown. These findings suggest that PYN90774 contributes to the activation of monocytes in patients with essential hypertension, potentially promoting vascular disease.

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
