The glycoproteins of selected microbial pathogens often include highly modified carbohydrates such as 2,4-diacetamidobacillosamine (diNAcBac). These glycoconjugates are involved in host-cell interactions and may be associated with the virulence of medically significant Gram-negative bacteria. In light of genetic studies demonstrating the attenuated virulence of bacterial strains in which modified carbohydrate biosynthesis enzymes have been knocked out, we are developing small molecule inhibitors of selected enzymes as tools to evaluate whether such compounds modulate virulence. We performed fragment-based and high-throughput screens against an amino-sugar acetyltransferase enzyme, PglD, involved in biosynthesis of UDP-diNAcBac in Campylobacter jejuni. Herein we report optimization of the hits into potent small molecule inhibitors (IC50 300 nM). Biophysical characterization shows that the best inhibitors are competitive with acetyl coenzyme A and an X-ray cocrystal structure reveals that binding is biased toward occupation of the adenine subpocket of the AcCoA binding site by an aromatic ring.

Synthesis and antihyperlipidemic activity of a series of novel condensed 2-chloroalkyl-4-chloro/hydroxy-5,6-di-substituted pyrimidines are described. The design of these compounds is based on the earlier QSAR study on the antihyperlipidemic 2-substituted
