摘要：

RECENT evidence suggests that serotonin may function to regulate the sensitivity of the circadian clock to the resetting effect of environmental light. Here we report that systemic administration of NAN-190, a drug that acts at both postsynaptic and somatodendritic serotonin receptors, potentiates light-induced phase shifts by as much as 250%. The effects of the drug are dose-related and are significant at light intensities between 0.2 and 200 lux. It is proposed that drugs with pharmacological properties similar to NAN-190 may prove useful as chronobiologics to adjust the sensitivity of the circadian system to natural 'zeitgebers'.
