This invention relates to antibacterial and anti-mycobacterial drug compounds of formula I. It also relates to pharmaceutical formulations of antibacterial drug compounds. It also relates to uses of the derivatives in treating bacterial infections and to methods of treating bacterial infections. The invention is also directed to antibacterial drug compounds which are capable of treating bacterial infections which are currently hard to treat with existing drug compounds, e.g. those caused by resistant bacterial or mycobacterial strains.

Optically pure isomers of 7-[3-(1,1-dialkylmethyl-1-amino)-1-pyrrolidinyl]quinolones and naphthyridones as therapeutically active and safe antibacterial agents are described, as well as pharmaceutical compositions thereof, and a method of treating bacterial infections therewith. Also described is a method of manufacture of the quinolones and naphthyridones as well as the starting materials, the optically pure pyrrolidine moieties for attachment at the 7-position.
previously-reported novel tricyclic topoisomerase inhibitors (NTTIs), we disclose the discovery of REDX07965, which has an MIC90 of 0.5 μg mL−1 against Staphylococcus aureus, favourable in vitro pharmacokinetic properties, selectivity versus human topoisomerase II and an acceptable toxicity profile. The results herein validate a rational design approach to address the urgent unmet medical need for novel antibiotics
