Abstract
Arenaviridae is a viral family whose members are associated with rodent-transmitted infections to humans responsible of severe diseases. The current lack of a vaccine and limited therapeutic options make the development of efficacious drugs of high priority. The cap-snatching mechanism of transcription of Arenavirus performed by the endonuclease domain of the L-protein is unique and essential, so we developed a drug design program targeting the endonuclease activity of the prototypic Lymphocytic ChorioMeningitis Virus. Since the endonuclease activity is metal ion dependent, we designed a library of compounds bearing chelating motifs (diketo acids, polyphenols, and N-hydroxyisoquinoline-1,3-diones) able to block the catalytic center through the chelation of the critical metal ions, resulting in a functional impairment. We pre-screened 59 compounds by Differential Scanning Fluorimetry. Then, we characterized the binding affinity by Microscale Thermophoresis and evaluated selected compounds in in vitro and in cellula assays. We found several potent binders and inhibitors of the endonuclease activity. This study validates the proof of concept that the endonuclease domain of Arenavirus can be used as a target for anti-arena-viral drug discovery and that both diketo acids and N-hydroxyisoquinoline-1,3-diones can be considered further as potential metal-chelating pharmacophores.

Abstract
Antimicrobial resistance (AMR) is a major health problem worldwide, because of ability of bacteria, fungi and viruses to evade known therapeutic agents used in treatment of infections. Aryldiketo acids (ADK) have shown antimicrobial activity against several resistant strains including Gram-positive Staphylococcus aureus bacteria. Our previous studies revealed that ADK analogues having bulky alkyl group in ortho position on a phenyl ring have up to ten times better activity than norfloxacin against the same strains. Rational modifications of analogues by introduction of hydrophobic substituents on the aromatic ring has led to more than tenfold increase in antibacterial activity against multidrug resistant Gram positive strains. To elucidate a potential mechanism of action for this potentially novel class of antimicrobials, several bacterial enzymes were identified as putative targets according to literature data and pharmacophoric similarity searches for potent ADK analogues. Among the seven bacterial targets chosen, the strongest favorable binding interactions were observed between most active analogue and S. aureus dehydrosqualene synthase and DNA gyrase. Furthermore, the docking results in combination with literature data suggest that these novel molecules could also target several other bacterial enzymes, including prenyl-transferases and methionine aminopeptidase. These results and our statistically significant 3D QSAR model could be used to guide the further design of more potent derivatives as well as in virtual screening for novel antibacterial agents.
