Abstract
Nicotinamide adenine dinucleotide kinases (NAD kinases) are essential and ubiquitous enzymes involved in the production of NADP(H) which is an essential cofactor in many metabolic pathways. Targeting NAD kinase (NADK), a rate limiting enzyme of NADP biosynthesis pathway, represents a new promising approach to treat bacterial infections. Previously, we have produced the first NADK inhibitor active against staphylococcal infection. From this linear di-adenosine derivative, namely NKI1, we designed macrocyclic analogues. Here, we describe the synthesis and evaluation of an original series of cyclic diadenosine derivatives as NADK inhibitors of two pathogenic bacteria, Listeria monocytogenes and Staphylococcus aureus. The nature and length of the link between the two adenosine units were examined leading to sub-micromolar inhibitors of NADK1 from L. monocytogenes, including its most potent in vitro inhibitor reported so far (with a 300-fold improvement compared to NKI1).

Eur J Med Chem 2016; 124:1041-1056.

Abstract
Increased resistance of pathogens to existing antibiotics necessitates the search for novel targets to develop potent antimicrobials. Biosynthetic pathways of several cofactors important for bacterial growth, such as nicotinamide adenine dinucleotide phosphate (NADP), have been proposed as a promising source of antibiotic targets. Nicotinamide adenine dinucleotide kinases (NADK; EC 2.7.1.23) are attractive for inhibitor development, since they catalyze the phosphorylation of NAD to NADP, which is an essential step of NADP metabolism. We previously synthesized diadenosine derivatives that inhibited NADK from two human pathogens, Listeria monocytogenes and Staphylococcus aureus, in the micromolar range. They behave as NAD mimics with the 5',5'-diphosphate group substituted by a 8,5' thioglycolic bridge. In an attempt to improve inhibitory potency, we designed new NAD mimics based on a single adenosine moiety harboring a larger derivatization attached to the C8 position and a small group at the 5' position. Here we report the synthesis of a series of 8-thioalkyl-adenosine derivatives containing various aryl and heteroaryl moieties and their evaluation as inhibitors of L. monocytogenes NADK1, S. aureus NADK and their human counterpart. Novel, sub-micromolar inhibitors of LmNADK1 were identified. Surprisingly, most LmNADK1 inhibitors demonstrated a high selectivity index against the close staphylococcal ortholog and the human NADK. Structural characterization of enzyme-inhibitor complexes revealed the original binding mode of these novel NAD mimics.
