Inhibitors of Acetyltransferase Domain of N-Acetylglucosamine-1-Phosphate-Uridyltransferase/ Glucosamine-1-Phosphate-Acetyltransferase (Glmu). Part 1: Hit to Lead Evaluation of a Novel Arylsulfonamide Series.
Bioorg.Med.Chem.Lett., 22:1510-, 2012

PubMed Abstract: A novel arylsulfonamide-containing series of compounds represented by 1, discovered by highthroughput screening, inhibit the acetyltransferase domain of N-acetylglucosamine-1-phosphate-uridyltransferase/glucosamine-1-phosphate-acetyltransferase (GlmU). X-ray structure determination confirmed that inhibitor binds at the site occupied by acetyl-CoA, indicating that series is competitive with this substrate. This letter documents our early hit-to-lead evaluation of the chemical series and some of the findings that led to improvement in in-vitro potency against Gram-negative and Gram-positive bacterial isozymes, exemplified by compound 40.
