General Pharmacology of DWQ-013, A New Synthetic Quinolone Antibiotics (Effects on the Central Nervous System)

신규 합성 퀴놀론계 항생물질(DWQ-013)의 일반 약리 작용 -중추신경계에 대한 작용-

The general pharmacological effects of DWQ-013, a new synthetic quinolone antibacterial agent, were examined on the central nervous system in experimentral animals and the following results were obtained. Drug interaction of DWQ-013 with theophylline, fenbufen and nonsteroidal antiinflammatory drugs was also examined. DWQ-013 decreased touch escape effect on the general behavior and decreased body temperature at a concentration of 1000 mg/kg in mice. But DWQ 013 had no effect on the locomotor activity, rotarod perfomance and traction test in mice. Furthermore, DWQ-013 increased pentobarbital-induced sleeping time and affected the onset time in acetic acid-induced writhing test in mice. DWQ-013 reduced onset time and death time on strychnine-induced convulsions and death time on pentylenetetrazole-induced convulsions at a concentration of 1000 mg/kg in mice. But, the drug had no effect on the electroshock. DWQ-013 did not interact with fenbufen and any other NSAIDs but it did interact with theophylline. From these results, it could be suggested that DWQ-013 had less pharmacological effect than other quinolones on the central nervous system.
