Chemiluminescent analysis of the antioxidant and immunomodulation effects of several psychotropic drugs on peritoneal macrophages.

The present study describes the application of several chemiluminescent (CL) methods for evaluation of antioxidant and immunomodulation effects of psychotropic drugs upon phagocytes: KO2-induced luminal-dependent CL for detection of superoxide anion radicals in a pure chemical system; PMA- and A23187-induced CL of peritoneal macrophages for detection of free radicals in cell suspension; and CL, produced by the luciferase-catalyzed luciferin + ATP reaction, for evaluation of cell viability before and after drug application. These methods provide also a way to investigate the location of drug action. It was found that the psychotropic drugs in fluence the 'oxidative burst' of macrophages through two mechanisms: by expression of drug antioxidant properties and/or by a direct immunomodulation effect.

The synthesis and pharmacology of a novel benzodiazepine derivative, 1-(beta-methylsulfonylethyl)-5-(o-fluorophenyl)-7-chloro-1,3-dihydro-2H-1,4-benzodiazepin-2-one (ID-622).

The pharmacological profiles of a new benzodiazepine derivative, 1-(beta-methylsulfonylethyl)-5-(o-fluorophenyl)-7-chloro-1,3-dihydro-2H-1,4-benzodiazepin-2-one (ID-622), were shown. In anti-convulsant test, ID-622 was more potent than diazepam and medazepam when tested with pentylenetetrazol or bemegride, but was less potent than diazepam tested with strychnine or MES in mice. Taming effects of ID-622 were more potent than diazepam in both electroshock- and isolation-induced fighting mice tests, but were less potent in both septal rats and O.B. rats tests. ID-622 had only a weak influence on the spontaneous locomotor activity, and did not cause the righting reflex loss. In EEG, ID-622 increased fast activity and depressed hippocampal I-waves and amygdala after-discharge in cats. Acute toxicity of ID-622 was very low.
