LY393558

LY393558 is an inhibitor of serotonin (5-HT) reuptake (IC50 = 3.3 nM in rat cortical synaptosomes). It is selective for serotonin reuptake over norepinephrine reuptake in rat cortical synaptosomes (IC50 = 2,510 nM) but does inhibit 5-HT-induced [35S]GTPgammaS binding in cells expressing human 5-HT1B or 5-HT1D receptors (Kbs = 0.89 and 10.4 nM, respectively). LY393558 (30 mg/kg per day) reduces pulmonary vascular remodeling, increases in right ventricular systolic pressure, and the development of right ventricular hypertrophy in a mouse model of pulmonary arterial hypertension induced by overexpression of the serotonin transporter and hypoxia.Formal Name: 1-[2-[4-(6-fluoro-1H-indol-3-yl)-3,6-dihydro-1(2H)-pyridinyl]ethyl]-3,4-dihydro-3-(1-methylethyl)-6-(methylsulfonyl)-1H-2,1,3-benzothiadiazine, 2,2-dioxide.
