Two novel series of 2-pyridones were synthesized by transposition of the nitrogen of 4-quinolones to the bridgehead position. This subtle interchange of the nitrogenatom with a carbon atom yielded two novel heterocyclic nuclei, pyrido[1,2-alpha]pyrimidine and quinolizine, which had not previously been evaluated as antibacterial agents and were found to be potent inhibitors of DNA gyrase. Quinolizines

A series of thieno[2,3-6]pyridine derivatives, attached at the 2-position to a substituted anilino moiety, which are substituted in the 3-position by a carbonyl group linked to a pyrrolidin-1-yl ring which in turn forms part of a heteroatom-containing fused bicyclic ring system, being selective inhibitors of human MEK (MAPKK) enzymes, are accordingly of benefit in medicine, for example in the treatment of inflammatory, autoimmune, cardiovascular, proliferative (including oncological) and nociceptive conditions.

stereochemistry of the C-8 group are very important to the antibacterial profiles. Structuralmodifications of the C-8 group provide a useful means to improve the antibacterialactivities, physicochemical properties, and pharmacokinetic profiles. Manipulation of the C-8 group also allows us to generate analogues with the desired spectrum of activity, such as analogues that are selective against respiratory
