Abstract
Infrared and Raman spectra of 1-formylpiperazine (1-fp) have been recorded in the region of 4000-50 cm(-1). The conformational analysis, optimized geometric parameters, normal mode frequencies and corresponding vibrational assignments of 1-fp (C5H10N2O) have been examined by means of Becke-3-Lee-Yang-Parr (B3LYP) density functional theory (DFT) method together with 6-31++G(d,p) basis set. Furthermore, reliable conformational investigation and vibrational assignments have been made by the potential energy surface (PES) and potential energy distribution (PED) analyses, respectively. Calculations are carried out with the possible six conformational isomers of 1-fp, both in gas phase and in solution using benzene and methanol. The experimental and theoretical results indicate that B3LYP method provides satisfactory evidence for the prediction vibrational wavenumbers, and the normal chair conformation with equatorial substituents is not preferred due to the steric interaction.

Abstract
Twelve alkyl analogues (1-12) of the high-affinity serotonin transporter (SERT) inhibitor 6-nitroquipazine (6-NQ) were synthesized and studied using in vitro radioligand competition binding assays to determine their binding affinity (Ki ). The putative antidepressant activity of five of the binders with the highest SERT binding affinities was studied by the forced swim and locomotor activity mouse tests. The three-dimensional (3D) structures of 8 and 9 were determined using NOE NMR technique. Flexible docking of the compounds was undertaken to illustrate the binding of the compounds in the SERT model. Our results showed that several of the 6-NQ analogues are high-affinity SERT inhibitors and indicated that the octyl (8), decyl (10) and dodecyl (12) 6-NQ analogues exhibit moderate antidepressant activity.

Abstract
It is well known that 6-nitroquipazine exhibits about 150-fold higher affinity for the serotonin transporter (SERT) than quipazine and recently we showed quipazine buspirone analogues with high to moderate SERT affinity. Now we have designed and synthesized several 6-nitroquipazine buspirone derivatives. Unexpectedly, their SERT binding affinities were moderate, and much lower than that of the previously studied quipazine buspirone analogues. To explain these findings, docking studies of both groups of compounds into two different homology models of human SERT was performed using a flexible target-ligand docking approach (4D docking). The crystal structures of leucine transporter from Aquifex aeolicus in complex with leucine and with tryptophan were used as templates for the SERT models in closed and outward-facing conformations, respectively. We found that the latter conformation represents the most reliable model for binding of buspirone analogues. Docking into that model showed that the nitrated compounds acquire a rod like shape in the binding pocket with polar groups (nitro- and imido-) at the ends of the rod. 6-Nitro substituents gave steric clashes with amino acids located at the extracellular loop 4, which may explain their lower affinity than corresponding quipazine buspirone analogues. The results from the present study may suggest chemical design strategies to improve the SERT modulators.

Abstract
Five C2'-substituted 6-nitroquipazine (6-NQ) derivatives were prepared and evaluated in terms of their biological abilities (K(i)) to displace [(3)H]citalopram binding to serotonin transporter. The relationship between their structure and biological activities revealed that shorter alkyl groups tend to possess higher binding affinity. Both compounds 12a and 12c were found to have the equally highest binding affinity (K(i)=0.43+/-0.02 nM).

Abstract
A new generation of antidepressant agents could be represented by compounds with mixed activity as serotonin transporter (SERT) inhibitors and 5-HT(1A) receptor antagonists. We report here on the synthesis and evaluation of SERT and 5-HT(1A) receptor affinity of long-chain arylpiperazines obtained either by modifying 6-nitroquipazine into a long-chain arylpiperazine or by inserting a modified 6-nitroquipazine moiety or other structures endowed with SERT affinity into a long-chain arylpiperazine with 5-HT(1A) affinity. Among the compounds studied, 2-[4-(2-methoxyphenyl)piperazin-1-yl]-N-(6-nitro-2-quinolyl)ethylamine (21) and 1-(5-bromo-1,2,3,4-tetrahydronaphthalen-1-yl)-3-[4-(2-methoxyphenyl)-piperazin-1-yl]-1-propanone (24) showed good affinity values for SERT and 5-HT(1A) receptors (SERT: K(i) (inhibition constant)=71.8 and 62.8 nM; 5-HT(1A)K(i)=14.2 and 0.82 nM, respectively).

Abstract
A series of quipazine derivatives, previously synthesized to probe the 5-HT(3) receptor, was evaluated for its potential interaction with serotonin transporter (SERT). Some of them show nanomolar affinity for the rodent SERT comparable to or slightly higher than quipazine or N-methylquipazine. Subsequently a candidate was selected on the basis of its SERT affinity and submitted to a molecular manipulation of the basic moiety. The structure-affinity relationships obtained provided information on the role of the fused benzene ring of quipazine in the interaction with the SERT binding site and on the stereoelectronic requirements for the interaction of both the heteroaromatic component and the basic moiety. Moreover, the comparison of the structure-affinity relationships obtained in the present work with those concerning the interaction of these heteroarylpiperazine derivatives with 5-HT3 receptor suggested some molecular determinants of the selectivity SERT/5HT3 receptor.

On the basis of the structure-activity relationship (SAR) of 4-chloro-6-nitroquipazine (Ki = 0.03 nM) and 3-fluoropropyl-6-nitroquipazine (Ki = 0.32 nM), 3-alkyl-4-halo-6-nitroquipazines were synthesized and tested for their potential abilities in vitro to displace [3H]citalopram binding to the rat cortical membranes. Binding affinities of 3b and 4d were Ki = 2.70+/-0.32 and 2.23+/-0.46 nM, respectively. The syntheses of 3-alkyl-4-halo-6-nitroquipazine, their in vitro binding affinities, and the SAR of C3, C4 position in 6-nitroquipazine are described.

Abstract
3-(3-[18F]Fluoropropyl)-6-nitroquipazine ([18F]FPNQ) as a 5-HT transporter imaging agents was designed, synthesized, and evaluated. FPNQ was selected due to its potent in vitro biological activity (K(i)=0.32 nM) in rat brain cortical membranes. The 18F-labeled FPNQ was prepared by reaction of the propyl mesylate as a precursor with tetra-n-butylammonium [18F]fluoride generated under NCA conditions. The precursor mesylate was synthesized from commercially available hydrocarbostyril in nine steps in 21% overall yield. The specific activity of the [18F]FPNQ determined by radioreceptor assay was 27.0 GBq/micromol. Tissue distribution studies in mice showed the highest uptake in the frontal cortex (5.79 %ID/g) at 60 min post-injection.

Abstract
Cochlear serotonergic innervation is constituted by efferent fibers projecting both to the area below the inner and the outer hair cells. Previous detection of serotonin (5-HT) metabolites and 5-HT receptor mRNAs suggests the existence of serotonergic synaptic activity in the cochlea. The present study explores this possibility through the effect of 6-nitroquipazine (6-NQ), a 5-HT selective reuptake inhibitor, on the basal turnover of 5-HT. The concentrations of 5-HT and its metabolite 5-hydroxyindole-3-acetic acid (5-HIAA) were quantified by high performance liquid chromatography with electrochemical detection in blood-free cochleae of rats treated with 6-NQ or saline and kept under silent conditions. Treatment with 6-NQ induced a significant increase of the cochlear concentration of 5-HT and a significant reduction of 5-HIAA concentration with respect to saline treatment. These findings could indicate that 6-NQ induced the blockade of the 5-HT selective reuptake to the cochlear serotonergic fibers. This suggests that plasma membrane 5-HT transporters are present in cochlear serotonergic fibers. Even though the role of serotonergic innervation on cochlear physiology remains unknown, the existence of cochlear serotonergic synaptic activity is strongly supported by present contributions.

Abstract
Eleven 4-substituted derivatives of 6-nitroquipazine were synthesized and evaluated for their abilities to displace [3H]citalopram binding to the rat cortical synaptic membranes. Among them, 4-chloro-6-nitroquipazine was shown to possess the highest binding affinity (K(i=)0.03 nM) which was approximately 6 times higher than that of 6-nitroquipazine (K(i)=0.17 nM) itself. In this paper, we describe the syntheses of 4-substituted 6-nitroquipazine derivatives, the results of corresponding biological evaluation and the SAR study.
