that engages in a hydrogenbond with Gly 216. The first series of inhibitors has a m-chlorobenzyl moiety binding in the S1 pocket, and the second has a benzamidine moiety. When the adjacent hydrogenbond is present, the enhanced binding affinity per Å2 of hydrophobic contact surface in the S3 pocket improves by 75% and 59%, respectively, over the inhibitors lacking this hydrogenbond. This improvement

A potent and selective anthrax LF inhibitor 40, (2R)-2-[(4-fluoro-3-methylphenyl)sulfonylamino]-N-hydroxy-2-(tetrahydro-2H-pyran-4-yl)acetamide, was identified through SAR study of a high throughput screen lead. It has an IC50 of 54 nM in the enzyme assay and an IC50 of 210 nM in the macrophage cytotoxicity assay. Compound 40 is also effective in vivo in several animal model studies. (c) 2005 Elsevier Ltd.
