3-disubstituted-1-azetidinyl)-1,4-dihydro-6-fluoro-4- oxoquinoline- and -1,8-naphthyridine-3-carboxylic acids, with varied substituents at the 1-, 5-, and 8-positions, was prepared to study the effects on potency and physicochemical properties of the substituent at position 2 of the azetidine moiety. The activity of the title compounds was determined in vitro against Gram-positive and Gram-negative bacteria

de]-1,4-benzoxazine-6-carboxylic acids was synthesized to study the effect of the azetidine moiety on tricyclic quinolone antibacterial agents. A series of amino acid prodrugs of chiral naphthyridines 24a and 24b and quinolone 33a (cetefloxacin) was prepared and evaluated for antibacterial activity, solubility, and pharmacokinetic behavior.

The invention relates to compounds according to Formula (I): or a pharmaceutically acceptable salt thereof, wherein m, n, R1, R2, R3, R4, R5, x and y are as defined herein. Compounds according to Formula (I) are pharmacologically effective as potassium channel inhibitors, in particular inhibitors of the acetylcholine operated inward rectifying potassium channel current (i.e. IKACh blockers), and are believed to be useful in the treatment of cardiac arrhythmias, in particular supraventricular tacharrhythmias, such as atrial fibrillation and atrial flutter.
