Abstract:

G iven the current uncertain climate of pharmaceutical industry, with FDA approved NCEs continue to stagger, antibacterial discovery faces unprecedented challenges, however, huge opportunities exist because the well recognized medical need for new agents to fi ght MDR bacterial infections, such as conditions caused by MRSA and VRE, and also a strong industrial appeal for incentives to invest in this area with orphan drug status, for instance, be granted to novel therapeutics. Here we use one AstraZeneca discovery program to illustrate the challenges and opportunities. Th e inhibition of essential cell-wall targets, such as Glutamate Racemase (MurI), provides a great opportunity to design the next generation of antibacterials. Th is talk will be focused on the recent eff orts of discovering MurI inhibitors in Gram-positive bacteria and Gram-negative Helicobacter Pylori . Th e entire discovery process from High Th roughput Screening, Lead Identifi cation and Lead Optimization will be presented. Emphasis will be given to the demonstration of the power of HTS to discover allosteric enzyme inhibitors and Structural Activity Relationship development employing Structure-Based Drug Design approach
