4YVF - PubMed Abstract: 
Optimization of a new series of S-adenosyl-L-homocysteine hydrolase (AdoHcyase) inhibitors based on non-adenosine analogs led to very potent compounds 14n, 18a, and 18b with IC50 values of 13 ± 3, 5.0 ± 2.0, and 8.5 ± 3.1 nM, respectively. An X-ray crystal structure of AdoHcyase with NAD(+) and 18a showed a novel open form co-crystal structure. 18a in the co-crystals formed intramolecular eight membered ring hydrogen bond formations. A single crystal X-ray structure of 14n also showed an intramolecular eight-membered ring hydrogen bond interaction.
