    • Reduction with lithium aluminum hydride reagent only was not clean. A partial reduction of hydantoin was observed and reduction of trifluoromethyl group to difluoromethyl was noticed. On the other hand, the reduction with lithium aluminum hydride and aluminum chloride was clean, providing the desired product.

    • 1 antagonists were administered orally in 0.4% methylcellulose in distilled water at a dose of 1 mg/kg (unless otherwise stated) at various pretreatment times prior to injection of GR73632. Data are expressed as a percent decrease (% inhibition) in the amount of time spent foot tapping compared to vehicle-treated controls.

    • The energy-minimum conformations were generated using MCMM conformational search approach in MacroModel method as implemented in Schrödinger modeling package. 5000 steps of conformational search each followed by energy minimization using MMFF94s force field parameters were carried out for every compound.

    • 1 antagonists which carry basic center, the most efficacious urea antagonists are neutral, for example, compound 4b (clog P = 5.1; solubility in pH 7.4 buffer = 3 μM).
