The emergence of multidrug-resistant pathogens necessitates the search for new antibiotics acting on previously unexplored targets. Nicotinate mononucleotide adenylyltransferase of the NadD family, an essential enzyme of NAD biosynthesis in most bacteria, was selected as a target for structure-based inhibitor development. To this end, the inventors have identified small molecule compounds that inhibit bacterial target enzymes by interacting with a novel inhibitory binding site on the enzyme while having no effect on functionally equivalent human enzymes.

Bz-I and 2Pyr-I, the primary hydrogenbonding resembled that of the other members of the family, indicating that the interactions mediated via the iodine atom were complementary to rather than competitive with the hydrogen bonds. Two polymorphs of 4Pyr-I were found, and in both forms, a halogenbond was formed with the N(py) acceptor which was engaged in N–H···N hydrogen bonds in the other members of
