A series of 2-alkylamino nicotinamide analogs was prepared as orallyactive ghrelin receptor (ghrelinR) inverseagonists. Starting from compound 1, oral bioavailability was improved by modifying metabolically unstable sites and reducing molecular weight. Brain-permeable compound 33 and compound 24 with low brain permeability were tested in rat models of obesity; 30 mg/kg of compound 33 suppressed weight
