The hypothermic effect of the antihypoxant 2-aminobenztiazole

Abstract

BACKGROUND: One of the compounds studied at the Department of Pharmacology of the Kirov Military Medical Academy is a compound with a proven antihypoxic effect of 2-aminobenzothiazole (2-ABT). The mechanism of action of this substance is partially associated with the central action, and its protective effect may potentially be due to the general hypothermic effect. AIM: To determine the effect of 2-ABT on body temperature. MATERIALS AND METHODS: Experiments were carried out on 24 adult males of white outbred mice. 2-ABT was previously dissolved in 0.9% sodium chloride solution and administered intraperitoneally to mice at doses of 32.5 mg/kg (with proven antihypoxic effect), 21.7 mg/kg or 10.8 mg/kg. Rectal temperature was measured with an electronic thermometer DT-623 (China) before administration of the test substance, as well as 5, 30 and 60 minutes after the injection.RESULTS: Compound 2-ABT has a pronounced dose-dependent hypothermic effect. This effect is maximally expressed in a dose in which the compound has a proven antihypoxic property – 32.5 mg/kg. The hypothermic effect manifests itself within 5 minutes after administration, the maximum decrease in body temperature is observed after 30 minutes, while the effect persists for an hour. CONCLUSION: 2-ABT may be a promising compound for the creation of a drug for drug-induced (controlled) hypothermia.
