| Description: | Measuring its tissue levels 1 hour after administration of 10 mg/kg to mice, plasma levels were comparable after oral or i.p. administration (indicating good oral bioavailability), and brain tissue level was <2% of plasma level, indicating low brain penetrance/peripheral selectivity. 1 h after oral administration of compound 2 at 10 mg/kg dose in mice, the metabolite generation in plasma was monitored by LC-MS/MS. As expected, this compound underwent in vivo metabolism to liberate the amidine moiety and a metabolite (structure 41V in the FIG. 1). Besides CB1R antagonism, both intact compound and its metabolically cleaved amidine moiety were able to inhibit iNOS activity about 48% and 37% at 1 μM concentration in lung homogenates from LPS-treated mouse (FIG. 4). Mice with diet-induced obesity (DIO) mice were orally treated for 14 days with the compound 2 (10 mg/kg/day). |
