The effects of the diterpene sclareol glycol (SG) of the labdane family on rectal body temperature in rats were studied. Sclareol glycol induced dose-dependent changes in temperature. At the lowest dose (5 mg/kg) sG produced a decrease followed by an increase in temperature; at the middle dose it produced a decrease and at the largest dose, an increase in rectal temperature. Sclareol glycol caused changes in apomorphine-induced hypothermia (at the low and middle doses it reversed hypothermia, and at the high dose hypothermia was enhanced). Sclareol glycol produced a dose-dependent reversal of reserpine-induced hypothermia. These results suggest that the diterpene sclareol glycol induces changes in core body temperature by interacting with dopamine (DA) receptors and with the second messenger system of 3',5'-AMP in the brain thermoregulatory areas.
