Description: Pranoprofen (also known as Pyranoprofen), a potent and approved non-steroidal anti-inflammatory drugs (NSAIDs), is a COX inhibitor that has been used as an anti-inflammatory drug in ophthalmology. It inhibits ER stress-induced glucose regulated protein 78 (GRP78) expression, an ER-localized molecular chaperon. Pranoprofen also inhibits ER stress-induced CCAAT/enhancer-binding protein homologous protein (CHOP) expression, an apoptotic transcription factor.

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
In vitro activity: Pranoprofen inhibits ER stress-induced glucose regulated protein 78 (GRP78) expression, an ER-localized molecular chaperon. Pranoprofen inhibits ER stress-induced CCAAT/enhancer-binding protein homologous protein (CHOP) expression, an apoptotic transcription factor. Pranoprofen alone induces eIF2alpha phosphorylation, which is further increased by ER stress. Pranoprofen inhibits ER stress-induced X-box-binding protein 1 (XBP-1) splicing in the primary cultured glial cells. Pranoprofen (0.0625 to 1.0 g/L) has poignant cytotoxicity to human corneal endothelial (HCE) cells, and the extent of its cytotoxicity is dose- and time-dependent. Pranoprofen induces plasma membrane permeability elevation, DNA fragmentation, and apoptotic body formation, proving its apoptosis inducing effect on HCE cells. Pranoprofen above 0.0625 g/L has poignant cytotoxicity on HCE cells in vitro by inducing cell apoptosis, and should be carefully employed in eye clinic.
