Function
VNN1_HUMAN Amidohydrolase that hydrolyzes specifically one of the carboamide linkages in D-pantetheine thus recycling pantothenic acid (vitamin B5) and releasing cysteamine.[1] [2]
Publication Abstract from PubMed
Inflammatory bowel disease (IBD) is a clinically heterogeneous disease demanding more therapeutic targets and intervention strategies. Vanin-1, an oxidative stress-regulating protein, has emerged as a promising target for alleviating inflammation and oxidative stress. In this study, a series of thiazole carboxamide derivatives as vanin-1 inhibitors were designed and synthesized. The preferred compound, X17, demonstrated potent inhibition against vanin-1 at the protein, HT-29 cell, and tissue levels, whose binding mode with the target was confirmed via the cocrystal structure. X17 achieved a high bioavailability of 81% in rats, accompanied by concentration-dependent inhibition of serum vanin-1. In a DSS-induced mouse colitis model, X17 exhibited potent anti-inflammatory and antioxidant activities, repressing the inflammatory factor expressions and myeloperoxidase activity, elevating the colonic glutathione reserve, and restoring the intestinal barrier. Collectively, these findings depict the discovery of a potent vanin-1 inhibitor, providing an opportunity for further drug candidate development for treating IBD.
