Synthesis of a bicyclic delta-amino acid as a constrained Gly-Asn dipeptide isostere.

abstract：:One pathogenic mechanism of ethanol-induced liver injury is the excessive production of reactive oxygen species (ROS), which may result in alcoholic liver disease (ALD) characterized by cell death due to necrosis and apoptosis. Taurine was proved to protect against liver damage. However, whether taurine attenuates eth...
