The synthesis and the affinities for serotonin and tryptamine receptors of a series of N-oxy derivatives of tryptamine (6–8, 13–14) are reported. It was found that N-hydroxytryptamine (6) is a relatively selective ligand for the 5-HT1C receptor.

Twelve pigeons were successfully (ED 50 = 2.4 mg/kg PO) trained to discriminate the 5-HT 1A/B receptor agonist eltoprazine (5.0 mg/kg PO) from its vehicle in a fixed-ratio (FR)30 two-key operant drug discrimination procedure. Tests for generalization

1. In the present study we evaluated the receptor selectivity of the potent histamine H3 receptor antagonist, iodophenpropit (IPP) in comparison with the prototype antagonist, thioperamide. 2. IPP proved to be a potent competitive H3 receptor antagon

This paper describes the syntheses of several 1-aryl-4-(biarylmethylene)piperazines and the results of the determination of their affinity for D(2) and 5-HT(1A) receptors. A selection of these compounds was evaluated in vivo, resulting in the identif

From ancient history to present times, mankind has sought for anxiolytics, and various medications have been found and consequently used, at present culminating in heavy benzodiazepine use. Side-effects such as dependence and tolerance have always in

A series of novel bicyclic 1-heteroaryl-4-[omega-(1H-indol-3-yl)alkyl]piperazines was synthesized and evaluated on binding to dopamine D(2) receptors and serotonin reuptake sites. This class of compounds proved to be potent in vitro dopamine D(2) rec

Do all natural compounds have a distinct biological activity, or are most of them merely biosynthetic debris? Many natural compounds have important biological functions, and certainly many more of the ample 200,000 currently known will ultimately pro

‘There are more things between heaven and earth…’ Despite the progress of science during the past four centuries, Shakespeare's words did not lose their actuality. Knowledge about the etiology of diseases is still limited, and for many life-thr

Prospecting the full biodiversity of nature to find leads for new drugs is not necessary. Because finding leads is aimed at identifying biological activity, structure is of secondary importance. Furthermore, although natural chemical diversity might
