EF-7412
EF-7412 is a dual antagonist of the 5-HT1A receptor and dopamine D2 receptor, with Ki values of 27 nM and 22 nM, respectively. EF-7412 acts as an antagonist at both pre- and postsynaptic 5-HT1A receptor sites, blocking 8-OH-DPAT (HY-112061)-induced hypothermia, behavioral syndrome, and corticosterone elevation in vivo. EF-7412 increases hypothalamic 5-HIAA/5-HT and DOPAC/DA ratios, alters 5-HT and DA neuronal activity, and slightly decreases spontaneous motor activity. EF-7412 can be used for research on 5-HT1A/D2 receptor regulation and related neural pathways.

EF-7412 interacts with the rhodopsin-based 5-HT1A receptor transmembrane domain model via specific ionic and hydrogen bonds[1].
EF-7412 (compound 46) (15-90 min) potently binds to rat brain 5-HT1A (Ki = 27 nM) and D2 dopaminergic (Ki = 22 nM) receptors, with no significant affinity for α1-adrenergic, 5-HT2A, 5-HT3, 5-HT4, or benzodiazepine receptors[3].

EF-7412 (0.3-10 mg/kg; s.c.; single dose) acts as an antagonist at postsynaptic 5-HT1A receptors in rats, blocking both 8-OH-DPAT (HY-112061)-induced behavioral effects and corticosterone secretion without altering baseline measures[3].

Dosage:5 mg/kg; 10 mg/kg; 20 mg/kg; 0.5 mg/kg; 2.5 mg/kg; 40 mg/kg
-
Administration:s.c.; single dose
-
Result:Did not alter mouse rectal temperature at doses of 5, 10, and 20 mg/kg.
Completely blocked 8-OH-DPAT-induced hypothermia at 20 mg/kg when administered 15, 60, or 120 minutes before 8-OH-DPAT.
Increased the 5-HIAA/5-HT ratio in mouse hypothalamus at 10 mg/kg, an effect reversed by pretreatment with 8-OH-DPAT.
Increased the DOPAC/dopamine ratio in mouse hypothalamus at 10 mg/kg, an effect not reversed by 8-OH-DPAT.
Produced a significant slight decrease in spontaneous locomotor activity compared to vehicle controls at doses of 20 mg/kg and 40 mg/kg.
