(S)-10-[(S)-(8-Amino-6-azaspiro[3,4]octan-6-yl)]-9-fluoro-2, 3-dihydro-3-methyl-7-oxo-7H-pyrido[1,2,3-de][1,4]benzoxazine-6-carboxyli c acid hemihydrate (CAS 151390-79-3, DV-7751a) a new quinolone antibacterial agent, was examined for LD50 value, phototoxicity and convulsion inducing potential in laboratory animals. A single oral administration of DV-7751a induced soft stool in rats at 1000 and 2000 mg/ kg and in monkeys at 250 mg/kg and vomiting in monkeys at 500 mg/kg or more. A single intravenous administration caused a decrease in locomotor activity, respiratory depression, convulsion, pulmonary edema and death in rats and mice. The LD50 values with oral administration were more than 2000 mg/ kg for rats and mice and more than 250 mg/kg for monkeys, and those with intravenous administration were 164.3 mg/kg for rats of both sexes at an injection rate of 2 ml/min, 118.8 mg/kg for male rats and 104 to 125 mg/kg for female rats at 0.5 ml/min, and 184.7 mg/kg for male mice and 187.4 mg/kg for female mice. DV-7751a showed very weak phototoxicity in mice after single oral administration of 600 mg/kg, followed by UVA irradiation, but no convulsion after oral administration of 200 or 1000 mg/kg in combination with 4-biphenylacetic acid at 400 mg/kg.

The anti-inflammatory effects of five pyrazolidine derivatives on white mice and laboratory rats were studied using models of thermal aseptic inflammation and inflammation induced by injection of carragenin and histamine, as well as models of "cotton-ball granuloma" and epinephrine (adrenaline)-induced pulmonary edema. These effects were compared with those of the most commonly used non-steroid anti-inflammatory drugs, such as phenylbutazone (CAS 50-33-9) and diclofenac (CAS 15307-79-6). It was found that the pyrazolidine compounds studied induced a pronounced anti-inflammatory effect by inhibiting both the proliferative and exudative phases of inflammation. At the same time, as compared to natural non-steroid anti-inflammatory drugs, these compounds had a lower toxicity and induced neither gastric ulcers nor suppression of hemopoiesis.

Phosgene (carbonyl chloride, CAS 75-44-5) is a highly reactive gas of historical interest and current industrial importance. Phosgene has also proved to be a useful model for the study of those biochemical mechanisms that lead to permeability-type pulmonary edema (adult respiratory distress syndrome). In turn, the study of phosgene-induced adult respiratory distress syndrome has provided insights leading to revised treatment strategies for exposure victims. We summarized recent findings on the mechanisms of phosgene-induced pulmonary edema and their implications for victim management. In light of that research, we also provide a comprehensive approach to the management and treatment of phosgene exposure victims.
