The effects of two putative 5-HT1A antagonists, 4-(2'-methoxyphenyl)-1- [2'-[N-(2"-pyridinyl)-p-iodobenzamido]ethyl]piperazine (p-MPPI) and 4-(2'-methoxyphenyl)-1-[2'-[N-(2"-pyridinyl)-p- fluorobenzamido]ethyl]piperazine (p-MPPF), were examined in vivo in two tests of postsynaptic 5-HT1A receptor activation, hypothermia and reciprocal forepaw treading,

Pharmacology Biochemistry and Behavior, 1997
The behavioral effects of 8-OH-DPAT [0.5-10 mg/kg intraperitoneally (i.p.)] and (+) S-20499 (1-20 mg/kg IP), a recently synthesized 5-HT1A receptor full agonist, were examined over a 2-h period in mice in a neutral cage and, during the peak period of effect, in a runway, 8-OH-DPAT (1 and 10 mg/kg) and (+) S-20499 (10 and 20 mg/kg) blocked vertical ...

Ligand-5-HT1A receptor interaction
Il Farmaco, 2000In the present paper the general structure and pharmacophore of some 5-HT1A receptor ligands are described. For several compounds (approximately 15) the intrinsic activity in lower lip retraction (postsynaptic, rat) and hypothermia (presynaptic, mice) tests was determined. For the identified functional presynaptic agonists and antagonists the influence

The 5-HT1A receptor: an overview of recent advances
Neurochemical Research, 1991Progress in the field of neuronal receptor research has accelerated during the last few years due to developments in pharmacology and molecular biology. This is particularly true in the case of the serotonin 5-HT1A receptor. In 1983 the very selective, high affinity 5-HT1A agonist 8-OH-DPAT was developed which allowed the pharmacology and distribution ...

Development of 5-HT1A receptor antagonists
Behavioural Brain Research, 1995The discovery that non-benzodiazepine anxiolytic agents such as buspirone bind with high affinity to the 5-HT1A receptor has stimulated the development of selective 5-HT1A receptor ligands as potential drug candidates. However, the lack of selective 5-HT1A receptor antagonists has hampered the elucidation of the mechanism of action of these agents ...

Antipeptide antibodies against the 5-HT1A receptor
Journal of Chemical Neuroanatomy, 1992The availability of the primary amino acid sequence for a large number of molecules provides a fruitful opportunity for their cellular localization by utilizing the procedure of antipeptide antibody formation. This procedure permits a synthetic peptide sequence to be attached to a carrier molecule for the purpose of inoculating an animal to raise ...

5-HT1A receptor antagonists and lordosis behavior
Neuropharmacology, 1996In proestrous rats, serotonin 1A (5-HT1A) receptor agonists inhibit lordosis behavior within 5-15 min following infusion into the ventromedial nucleus of the hypothalamus (VMN). In the present report, the lordosis-inhibiting effects of the 5-HT1A agonist [(+/-) 8-hydroxy-2- (di-n-propylamino) tetralin) (8-OH-DPAT] were shown to be attenuated with 5 ...

Agonistic Properties of Cannabidiol at 5-HT1a Receptors
Neurochemical Research, 2005Cannabidiol (CBD) is a major, biologically active, but psycho-inactive component of cannabis. In this cell culture-based report, CBD is shown to displace the agonist, [3H]8-OH-DPAT from the cloned human 5-HT1a receptor in a concentration-dependent manner.

Brain 5-HT receptors have been classified in at least six subtypes (5-HT1A, 1B, 1C, 1D, 2 AND 3; Peroutka, 1988), among which the 5-HT1A subtype has been the focus of intense research during the last few years. This receptor type is located both presynaptically on the 5-HT cell bodies (somatodendritic receptors), predominantly in the dorsal and median ...

5-HT1A receptors and alcohol preference
European Neuropsychopharmacology, 1993Abstract Microinjection and lesion studies support the involvement of presynaptic 5-HT1A receptors in the reduction of ethanol (EtOH) intake induced by the selective 5-HT1A receptor agonists 8-OH-DPAT and ipsapirone in selectively bred Wistar rats, with high preference for EtOH over water in a two-bottle free choice situation.
