This invention is in the field of medicinal chemistry and relates to compounds, and pharmaceutical compositions thereof, that inhibit bacterial gyrase. The compounds are useful as inhibitors of bacterial gyrase activity and bacterial infections, and have the structure of Formula (I) as further described herein. The invention further provides pharmaceutical compositions comprising a compound of Formula (I) and methods of using the compounds and compositions to treat bacterial infections.
The present invention relates to compounds of Formula (I),
or a form thereof, wherein ring A, R
1
, L and R
2
are as defined herein, useful as FLAP modulators. The invention also relates to pharmaceutical compositions comprising compounds of Formula (I). Methods of making and using the compounds of Formula (I) are also within the scope of the invention.

reference ligand for labelling the 5-HT(4) serotoninergic receptors. Previous works in our laboratories established the bioisosteric equivalency of the indole heterocycle and naphthalene in a series of melatoninreceptorligands. Based on this knowledge we designed new analogues of GR 113808 by introducing two bioisosteric modifications: firstly, the indole ring was replaced by a naphthalene one and
