The hypothermic effect of the antihypoxant 2-aminobenztiazole

BACKGROUND:The compound 2-aminobenzothiazole (2-ABT), which has a proven antihypoxic effect, was studied at the Department of Pharmacology of the Kirov Military Medical Academy. The mechanism of action of this substance is partially associated with the central action, and its protective effect may be due to the general hypothermic effect. AIM:To determine the effect of 2-ABT on body temperature. MATERIALS AND METHODS:Twenty-four male adult white outbred mice were studied. Moreover, 2-ABT was 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, and 10.8 mg/kg. Rectal temperature was obtained with an electronic thermometer (DT-623, China) before administration of the test substance and at 5, 30, and 60 min 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 was evident within 5 min after administration. Additionally, the maximum decrease in body temperature was observed after 30 min, whereas the effect persisted for 1 h. CONCLUSIONS:2-ABT may be a promising compound for developing a drug for drug-induced (controlled) hypothermia.
