MedKoo CAT#: 522495

CAS#: 439083-90-6

Description: BAY-60-7550 is a potent PDE2 inhibitor with IC50 values of 2.0 nM (bovine) and 4.7 nM (human). BAY-60-7550 antagonizes oxidative stress-induced anxiety-like behavioral effects in mice by increasing cGMP signaling. Phosphodiesterases (PDEs) are key regulatory enzymes of intracellular cAMP/cGMP levels. These second messengers play important regulatory roles in controlling steroidogenesis in the adrenal. Disruption of PDEs has been associated with a number of adrenal diseases
