BAY-60-7550 is a potent Type 2 cyclic nucleotide phosphodiesterases (PDE2) inhibitor with IC50 values of 2.0 nM (bovine) and 4.7 nM (human). BAY-60-7550 is an analog of EHNA, which is more than 100-fold more potent and is highly selective for PDE2A.

Cell lines | human distal pulmonary artery smooth muscle cells |
Preparation method | Cell proliferation. Growth of human distal pulmonary artery smooth muscle cells isolated from patients with idiopathic pulmonary arterial hypertension (IPAH) or control cells from adults undergoing transplant or lung resection for suspected malignancy, were monitored as we have described previously 29 following treatment with BAY 60-7550 (1μmol/L), ANP (1μmol/L), DETA-NONOate (10μmol/L), or treprostinil (1μmol/L), alone or in combination. |

Body Surface Area (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
