Application

BAY 73-6691 has been used as a phosphodiesterase 9 inhibitor in ischemic heart samples and in structural studies. It may be used as a PDE 9 inhibitor in neuroblastoma SH-SY5Y cells.

Biochem/physiol Actions

BAY 73-6691 was characterized in vitro as the first potent and selective inhibitor of phosphodiesterase 9 (PDE9), which is currently under preclinical development for the treatment of Alzheimer′s disease. This compound selectively inhibits human (IC50 = 55 nM) and murine (IC50 = 100 nM) PDE9 activity in vitro and shows only moderate activity against other cyclic nucleotide-specific phosphodiesterases. BAY 73-6691 alone did not significantly increase basal cGMP levels. The PDE9 inhibitor significantly potentiated the cGMP signals generated by sGC activating compounds such as BAY 58-2667 or 5-cyclopropyl-2-[1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridin-3-yl]pyrimidin-4-ylamine (BAY 41-2272) and induced leftward shifts of the corresponding concentration-response curves. The newly generated PDE9 reporter cell line show that BAY 73-6691 is able to efficiently penetrate cells and to inhibit intracellular PDE9 activity.†

Supressed levels of intracellular cAMP have been associated with malignancy. Thus, elevating cAMP through activation of adenylyl cyclase (AC) or by inhibition of phosphodiesterase (PDE) may be therapeutically beneficial. Here, we demonstrate that elevated cAMP levels suppress growth in C6

Cyclic nucleotides, including cyclic AMP (cAMP), cyclic GMP (cGMP) and cyclic ADP-ribose, have been extensively studied as second messengers of intracellular events initiated by activation of GPCRs. cAMP modifies cell function in all eukaryotic cells, principally through the activation of cAMP-dependent protein kinase (PKA), but also through cAMP-gated ion channels and guanine nucleotide exchange factors directly activated by cAMP.
