The discovery and development of new antibiotics capable of curing infections due to multidrug-resistant and pandrug-resistant Gram-negative bacteria are a major challenge with fundamental importance to our global healthcare system. Part of our broad program at Novartis to address this urgent, unmet need includes the search for new agents that inhibit novel bacterial targets. Here we report the discovery and hit-to-lead optimization of new inhibitors of phosphopantetheine adenylyltransferase (PPAT) from Gram-negative bacteria. Utilizing a fragment-based screening approach, we discovered a number of unique scaffolds capable of interacting with the pantetheine site of E. coli PPAT and inhibiting enzymatic activity, including triazolopyrimidinone 6. Structure-based optimization resulted in the identification of two lead compounds as selective, small molecule inhibitors of bacterial PPAT: triazolopyrimidinone 53 and azabenzimidazole 54 efficiently inhibited E. coli and P. aeruginosa PPAT and displayed modest cellular potency against the efflux-deficient E. coli ΔtolC mutant strain.
MONO AND BICYCLIC RING BORONIC ACID, ESTER AND SALT COMPOUNDS AS INHIBITORS OF P97 COMPLEX

Page/Page column 405; 406, (2016/12/26)
Monocyclic or bicyclic ring boronic acid or ester compounds having an arylalkyi amine substituent at the 4 position and a substituted 5:6 bicyclic group at the 2 position of the mono or bicyclic ring boronic acid or ester as well as optional aliphatic, functional and/or aromatic components substituted at other positions of the mono or bicyclic boronic acid or ester compounds are disclosed. These compounds are inhibitors of the AAA proteasome complex containing p97 and are effective medicinal agents for treatment of diseases associated with the Valosin containing protein and p97 bioactivity such as cancer.
