Is NAN-190 an effective antagonist of the hypothermia and hyperglycemia induced by the 5-HT1A receptor agonist, 8-OH-DPAT?

Abstract:

:The putative 5-HT1A receptor antagonist properties of 1-(2-methoxyphenyl)-4-[4-(2-phtalimmido)butyl] piperazine (NAN-190) were studied in mice. The responses studied were hypothermia- and hyperglycemia-induced by the 5-HT1A agonist, 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT). NAN-190 (0.3-3 mg/kg) did not antagonize either response, but rather appeared to be additive with the effect produced by 8-OH-DPAT (0.25 mg/kg) alone, at least with respect to temperature. NAN-190, given alone in similar doses, caused hypothermia and hyperglycemia. These results suggest that NAN-190 has similar properties to 8-OH-DPAT with regard to temperature and glucose effects. Therefore, it does not appear to be a effective antagonist for all 5-HT1A-mediated responses.
