| 描述 | FOY 251 is an anti-proteolytic active derivative of Camostate, serves as a proteinase inhibitor[1].[2]. FOY 251 impede SARS-CoV-2 infection in cellular assays and exhibits a dose-responsive inhibition of equivalent current in M-1 cells[1].[2].[3]. |

| Mice | Diet-induced obese (DIO) mice | Oral | 100 mg/kg | Acute experiment: single dose; Chronic experiment: 4 weeks | To evaluate the effects of FOY-251 on gallbladder contraction, delayed gastric emptying, and food intake, as well as its metabolic effects via CCK1R signaling. Results showed that FOY-251 induced weight loss through both CCK1R-dependent and -independent mechanisms, improving metabolism. | PLoS One. 2025 Jun 3;20(6):e0312927 |
