A series of novel benzimidazoles are discussed as NR2B-selective N-methyl-d-aspartate (NMDA) receptor antagonists. High throughput screening (HTS) efforts identified a number of potent and selective NR2B antagonists such as 1. Exploration of the substituents around the core of this template identified a number of compounds with high potency for NR2B (pIC50 >7) and good selectivity against the NR2A

where A is an alkylene chain of 1 or 2 carbon atoms optionally substituted by one or more lower alkyl groups, R is hydrogen or lower alkyl, R1 is a mono or bicyclic aryl or a heteroaryl radical, R2 is an aryl radical, a heteroaryl radical, or an aryl-or heteroaryl-lower alkyl radical, R3 is hydrogen, lower alkyl or aryl and R4 is hydrogen, lower alkyl, cycloalkyl, cycloalkyl(lower)alkyl, aryl, or aryl(lower)alkyl or R3 and R4 together with the nitrogen atom to which they are both attached represent a saturated heterocyclic ring which may contain a further hetero atom and the dotted line represents a single or double bond, the hydrogen atoms shown in brackets being present when the dotted line represents a single bond and their pharmaceutically acceptable acid addition salts are 5-HT1A binding agents which may be used, for example, for the treatment of CNS disorders such as anxiety.
1,4-Dihydro-4-oxopyridinecarboxylic acids as antibacterial agents. 2. Synthesis and structure-activity relationships of 1,6,7-trisubstituted 1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic acids, including enoxacin, a new antibacterial agent
or unsubstituted 1-piperazinyl groups were introduced as the C-7 variants. As a result of this study, 1-ethyl-6-fluoro-1,4-dihydro-4-oxo-7-(1-piperazinyl)-1, 8-naphthyridine-3-carboxylic acid (named enoxacin, originally AT-2266) was found to show the most broad and potent in vitro antibacterialactivity, an excellent in vivo efficacy on systemic infections, and a weak acute toxicity.
