Abstract
Modulating the glucose transport in skeletal muscle is a promising strategy for ameliorating glucose homeostasis disorders. However, the complicated mechanisms of glucose transport make it difficult to find compounds therapeutically relevant molecular mechanisms of action, while phenotypic screening is thought to be an alternative approach to mimic the cell state of interest. Here, we report (±)-seneciobipyrrolidine (1a) is first found to enhance glucose uptake in L6 myotubes through phenotype-based screening. Further SAR investigation led to the identfication of compound A27 (EC50 = 2.7 μM). Proteomiic analysis discloses the unique function mechanism of A27 through upregulating the level of the eukaryotic translation initiation factor 4E-binding protein 1 (4E-BP1), subsequently enhancing the Akt and AMPK phosphorylation, thereby promoting the glucose uptake. Chronic oral administration of A27 significantly lowers blood glucose and improves glucose tolerance in db/db mice. This work is new research on seneciobipyrrolidine derivatives, providing a promising avenue for ameliorating glucose homeostasis.

Abstract
A series of N-skatyltryptamines was synthesized and their affinities for serotonin and dopamine receptors were determined. Compounds exhibited activity toward 5-HT1A, 5-HT2A, 5-HT6, and D2 receptors. Substitution patterns resulting in affinity/activity switches were identified and studied using homology modeling. Chosen hits were screened to determine their metabolism, permeability, hepatotoxicity, and CYP inhibition. Several D2 receptor antagonists with additional 5-HT6R antagonist and agonist properties were identified. The former combination resembled known antipsychotic agents, while the latter was particularly interesting due to the fact that it has not been studied before. Selective 5-HT6R antagonists have been shown previously to produce procognitive and promnesic effects in several rodent models. Administration of 5-HT6R agonists was more ambiguous-in naive animals, it did not alter memory or produce slight amnesic effects, while in rodent models of memory impairment, they ameliorated the condition just like antagonists. Using the identified hit compounds 15 and 18, we tried to sort out the difference between ligands exhibiting the D2R antagonist function combined with 5-HT6R agonism, and mixed D2/5-HT6R antagonists in murine models of psychosis.

Abstract
Clozapine-like compound without agranulocytosis risk is need to cure the treatment resistant schizophrenia (TRS). We discovered (S)-3 as Clozapine-like dopamine D2/D1 receptor selectivity and improved reactive metabolites formation profile by the modification of piperazine moiety in Clozapine. The optimization of (S)-3 gave compound 5 to be best compound (approximately 10-fold stronger affinity for D2/D1 receptor and similar D2/D1 selectivity ratio with Clozapine). Clozapine-like D2/D1 receptor occupancy profile was proved by in vivo evaluation. In addition, the reactive metabolites derived agranulocytosis risk of compound 5 was considered to be lower than Clozapine. The pharmacology detail of compound 5 is being investigated to develop it for TRS treatment.

Abstract
The design of a series of novel flavone derivatives was synthesized as potential broad-spectrum antipsychotics by using multi-receptor affinity strategy between dopamine receptors and serotonin receptors. Among them, 7-(4-(4-(6-fluorobenzo[d]isoxazol-3-yl) piperidin- 1-yl) butoxy)-2,2-dimethylchroman-4-one (6j) exhibited a promising preclinical profile. Compound 6j not only showed high affinity for dopamine D2, D3, and serotonin 5-HT1A, 5-HT2A receptors, but was also endowed with low to moderate activities on 5-HT2C, α1, and H1 receptors, indicating a low liability to induce side effects such as weight gain, orthostatic hypotension and QT prolongation. In vivo behavioral studies suggested that 6j has favorable effects in alleviating the schizophrenia-like symptoms without causing catalepsy. Taken together, compound 6j has the potential to be further developed as a novel atypical antipsychotic.

Abstract
In this study, a series of compounds derived from 4-methoxy-1H-isoindole-1,3(2H)-dione, potential ligands of phosphodiesterase 10A and serotonin receptors, were investigated as potential antipsychotics. A library of 4-methoxy-1H-isoindole-1,3(2H)-dione derivatives with various amine moieties was synthesized and examined for their phosphodiesterase 10A (PDE10A)-inhibiting properties and their 5-HT1A and 5-HT7 receptor affinities. Based on in vitro studies, the most potent compound, 18 (2-[4-(1H-benzimidazol-2-yl)butyl]-4-methoxy-1H-isoindole-1,3(2H)-dione), was selected and its safety in vitro was evaluated. In order to explain the binding mode of compound 18 in the active site of the PDE10A enzyme and describe the molecular interactions responsible for its inhibition, computer-aided docking studies were performed. The potential antipsychotic properties of compound 18 in a behavioral model of schizophrenia were also investigated.

Abstract
In the present study, a series of multi-target N-substituted cyclic imide derivatives which possessed potent dopamine D2, serotonin 5-HT1A and 5-HT2A receptors properties were synthesized and evaluated as potential antipsychotics. Among these compounds, (3aR,4R,7S,7aS)-2-(4-(4-(benzo[b]thiophen-4-yl)piperazin-1-yl)butyl)-3a,4,7,7a-tetrahydro-1H-4,7-methanoisoindole-1,3(2H)-dione hydrochloride (3d) held a promising pharmacological profile. 3d not only showed potent and balanced in vitro activities on D2/5-HT1A/5-HT2A receptors, but also endowed with low to moderate activities on 5-HT2C, H1, α1A, M3 receptors and hERG channel, suggesting a low liability to induce side effects such as weight gain, orthostatic hypotension and QT prolongation. In animal behavioral studies, 3d reduced phencyclidine-induced hyperlocomotion with a high threshold for catalepsy induction. Compound 3d was selected as a potential antipsychotic candidate for further development.

Abstract
In this study, high surface area mesoporous silica foam with cellular pore morphology (MCF) was used for injectable delivery of paliperidone, an antipsychotic drug used in patients suffering from bipolar disorder. The aim was to enhance paliperidone solubility and simultaneously to prepare long active intractable microspheres. For this reason paliperidone was first loaded in MCF silica, and the whole system was further encapsulated into PLA and PLGA 75/25w/w copolymer in the form of microspheres. It was found that paliperidone, after its adsorption into MCF, was transformed in its amorphous state, thus leading to enhanced in vitro dissolution profile. Furthermore, incorporation of the drug-loaded MCF to polymeric microparticles (PLA and PLGA) prolonged the release time of paliperidone from 10 to 15days.

Abstract
Sigma 1 receptors are associated with neurodegenerative and psychiatric disorders. These receptors, via their chaperoning functions that counteract endoplasmic reticulum stress and block neurodegeneration, may serve as a target for a new generation of antidepressants or neuroprotective agents. The involvement of these receptors has also been observed in neuropathic pain and cancer. Only a few ligands, such as Igmesine and Anavex 2-73, have been involved in clinical trials. Thus the development of sigma 1 ligands is of interest to a new generation of drugs. Previous work in our lab underlined the potency of benzannulated bicyclic compounds as interesting ligands. Herein the work was extended to a series of novel tricyclic compounds. Carboline- and phenothiazine-derivated compounds were designed and synthesized. In vitro competition binding assays for sigma 1 and 2 receptors showed that most of them have high affinity for sigma 1 receptor (Ki = 2.5-18 nM), and selectivity toward sigma 2 receptor, without cytotoxic effects on SY5Y cells.

Abstract
Clozapine was the first true breakthrough in schizophrenia treatment since the discovery of chlorpromazine in 1950, effectively treating positive, negative, and some cognitive symptoms, as well as possessing unprecedented efficacy in treatment-resistant patients. Despite over 30 years of intense study, the precise molecular underpinnings that account for clozapine's unique efficacy remain elusive. In this Viewpoint, we will showcase the history and importance of clozapine to neuroscience in general, as well as for the treatment of schizophrenia, and review the synthesis, pharmacology, drug metabolism, and adverse events of clozapine.

Abstract
Dopamine (D(2)) partial agonists (D2PAs) have been regarded as a potential treatment for schizophrenia patients with expected better side effect profiles than currently marketed antipsychotics. Herein we report the synthesis and SAR of a series of aminothiazole fused benzazepines as selective D(2) partial agonists. These compounds have good selectivity, CNS drug-like properties and tunable D(2) partial agonism. One of the key compounds, 8h, has good in vitro/in vivo ADME characteristics, and is active in a rat amphetamine-induced locomotor activity model.

Abstract
We describe the discovery of a series of compounds based on 1-{3-[4-(2-oxo-2,3-dihydro-benzoimidazol-1-yl)-piperidin-1-yl]-propyl}-3,4-dihydro-1H-quinolin-2-one (3), showing combined D(2) receptor affinity and M(1) receptor agonism. Based on a strategy of controlling logP, we herein describe a hit-to-lead investigation with the aim of retaining the combined D(2)/M(1) profile, while removing the propensity of the compounds to inhibit the hERG channel, as well as at obtaining acceptable pharmacokinetic properties. Although a SAR was evident for all four parameters in question, it was not possible to separate hERG channel inhibition and D(2) receptor affinity by this effort; whilst it was feasible to obtain compounds with M(1) receptor agonism, acceptable clearance, and weak hERG inhibition.

Abstract
A series of orexin receptor antagonists was synthesized based on a substituted piperidine scaffold. Through traditional medicinal chemistry structure-activity relationships (SAR), installation of various groups at the 3-6-positions of the piperidine led to modest enhancement in receptor selectivity. Compounds were profiled in vivo for plasma and brain levels in order to identify candidates suitable for efficacy in a model of drug addiction.

Abstract
It is suggested that the ratio of dopamine D(2) to 5-hydroxytryptamine 5-HT(1A) activity is an important parameter that determines the efficiency of antipsychotic drugs. Here we present the synthesis of N-{[2-(4-phenyl-piperazin-1-yl)-ethyl]-phenyl}-2-aryl-2-yl-acetamides and 1-{[2-(4-phenyl-piperazin-1-yl)-ethyl]-phenyl}-3-aryl-2-yl-ureas and their structure-activity relationship studies on dopamine D(2) and 5-hydrohytryptamine 5-HT(1A) receptors. It was shown that ligand selectivity and affinity strongly depends on their topology and the presence of a pyridyl group in the head of molecules. Molecular modeling studies using homology modeling and docking simulation revealed a rational explanation for the ligand behavior. The observed binding modes and receptor-ligand interactions provided us with a clue for optimizing the optimal selectivity towards 5-HT(1A) receptors.

Abstract
Tridecapeptide neurotensin (NT) is known to exert the neuroleptic-like effects in case of its intracerebral administration. The group of systemically active dipeptides , acylprolyltyrosines, was constructed on the background of NT. Methyl ester of N-caproyl-L-prolyl-L-tyrosine (Dilept) was chosen for further development. The paper is dealing with main principles of Dilept'design and with analysis of the experimental data concerning its effect on the "translational" model of schizophrenia--the deficit of prepulse inhibition of the acoustic startle-reaction caused by either dopamine-mimetic, apomorphine, or by the uncompetitive NMDA-blocker, ketamine. Dilept was shown to attenuate these deficits both in case ofintraperitoneal and peroral administration. Dilept is considered as a potential antipsychotic.

Abstract
According to published data, peptide neurotensin is considered as endogenous antipsychotic agent. A series of oligopeptides have been synthesized based on the proposed active center of neurotensin. These oligopeptides (called neurotensin-like peptides, NLPs) have been studied on behavioral models, in which the functional state of the dopamine system of animals was modified by apomorphine injections. The results of verticalization, stereotypy, and yawning tests revealed NLPs that behave as antagonists of dopamine receptors. Radioligand analysis showed that these peptides compete for specific binding to these receptors with sulpiride, which is a D2-type selective antagonist of dopamine receptors. The high degree of NLPs efficiency manifested in the behavioral tests and radioligand analysis suggests that the their antipsychotic action can be mediated by dopamine receptors.

Abstract
As a part of an integrated quality concept in drug development, the multidimensional evaluation of impurity profiles by LC-MS/MS is presented for quetiapine--an active pharmaceutical ingredient (API). LC-UV is commonly employed for the determination of impurities and degradation products. In this work LCMS/MS technique is proposed as a modern alternative for the characterization of these compounds. The use of this technique allowed to develop methods for the separation and identification of the impurities resulting from both, synthesis and degradation processes.

Abstract
A series of aripiprazole (AR3) syntheses were performed at laboratory scale (10 mmol of the ARI substrate) in order to optimize the amount of another substrate AR2, as well as Na2CO3, ethanol and varying the reaction time. The reaction parameters were chosen according to the D-optimal plans. A high conversion ratio, about 90-99%, was obtained. Purity of crude product (AR3) was determined by HPLC. Molar content of crude reaction product was predicted theoretically with the use of the mass balance and the corresponding HPLC parameters. The theoretical predictions were verified with the potentiometric and thermogravimetric analysis of selected samples. Based on the predicted molar content of reaction mixtures, a series of reaction response surfaces was calculated and optimal set of reaction parameters for aripiprazole synthesis was determined.

Abstract
A series of nitrogen-containing benzoheterocyclic derivatives were synthesized and tested for their antipsychotic activities. Their structures were confirmed by 1H NMR and HR-MS. Preliminary in vitro pharmacological trials showed that most of the target compounds have high affinity with D2 and 5-HT(2A) receptors. Among the tested compounds, 20 exhibited the highest affinity and D2 partial agonist activity. In vivo studies showed 20 has potent antipsychotic activities on apomorphine mice model, which is a chance to find a better precursor of D2 partial agonist for further optimization.

Abstract
Clinical properties of atypical antipsychotics are based on their interaction with D(2) dopamine receptor and serotonin 5-HT(1A) and 5-HT(2A) receptors. As a part of our research program on new antipsychotics, we synthesized various derivatives of 1-cinnamyl-4-(2-methoxyphenyl)piperazines, and evaluated their affinities for D(2), 5-HT(1A), 5-HT(2A), and adrenergic (alpha(1)) receptors using radioligand-binding assays. In addition, we performed docking analysis using models for the D(2) and 5-HT(1A) receptors. All compounds exhibited low to moderate affinity to 5-HT(1A) and 5-HT(2A) receptors, high affinity to the D(2 )receptor and large variability in affinities for the alpha(1) receptor. Docking analysis indicated that the binding to D(2) and 5-HT(1A) receptors is based on (i) interaction between protonated N1 of the piperazine ring and various aspartate residues, (ii) hydrogen bonds between various moieties of the ligand and the residues of threonine, serine, histidine or tryptophane, and (iii) edge-to-face interactions of the aromatic ring of the arylpiperazine moiety with phenylalanine or tyrosine residues. Docking data for the D(2) receptor can account for the binding properties obtained in binding assays, suggesting that the model is reliable and robust. However, docking data for the 5-HT(1A) receptor cannot account for actual binding properties, suggesting that further refinement of the model is required.

Abstract
Chronic low-dose treatment of rats with the psychomimetic drug, phencyclidine, induces regionally specific metabolic and neurochemical changes in the CNS that mirror those observed in the brains of schizophrenic patients. Recent evidence suggests that drugs targeting serotoninergic and muscarinic receptors, and in particular 5-HT(7) antagonists and M(4) agonists, exert beneficial effects in this model of schizophrenia. Compounds that display this combined pattern of activity we refer to as serominic compounds. Based upon leads from natural product screening, we have designed and synthesised such serominic compounds, which are principally arylamidine derivatives of tetrahydroisoquinolines, and shown that they have the required serominic profile in ligand binding assays and show potential antipsychotic activity in functional assays.

Abstract
Four new diaza analogues (14, 15, 23, and 24) of the conformationally constrained aminobutyrophenone derivatives QF0104B (5) and QF0108B (6) were synthesized (Schemes 2 and 3), and evaluated for their binding affinities (Table) towards the serotonin 5-HT2A and 5-HT2C, and the dopamine D2 receptors. Among the new compounds, the quinazoline derivative 15 (= 7-{[4-(4-fluorobenzoyl)piperidin-1-yl]methyl}-5,6,7,8-tetrahydroquinazolin-5-one) exhibited the highest affinities towards the serotonin 5-HT2A and dopamine D2 receptors, and it is in the borderline of potential atypical antipsychotics. The cinnoline derivative 23 (= 7-{[4-(4-fluorobenzoyl)piperidin-1-yl]methyl}-5,6,7,8-tetrahydro-3-methylcinnolin-5-one) displayed high selectivity in its binding profile towards the 5-HT2C compared to both the 5-HT2A and D2 receptors.

Abstract
As part of a continuing effort to design and synthesize highly selective muscarinic agonists for different muscarinic receptor subtypes, several tetra(ethylene glycol)(3-methoxy-1,2,5-thiadiazol-4-yl) [3-(1-methyl-1,2,5,6-tetrahydropyrid-3-yl)-1,2,5-thiadiazol-4-yl] ether (1) analogues were prepared and characterized. Different analogues were synthesized having hydrophilic spacers of di-, tri-, tetra-, penta(ethylene glycol) and tri(propylene glycol) separating the 1,2,5,6-tetrahydropyridine ring from the terminal heterocycle, which was either a 1,2,5-thiadiazole or 1,2,4-thiadiazole ring. Chimeric receptor and molecular modeling studies also were conducted to determine how the ligands interact with muscarinic receptors. The studies revealed that varying the distance of the terminal thiadiazole and the positioning of the methoxy group can increase binding affinity for certain muscarinic receptor subtypes (at M(2) for 13d and M(4) for 1) and enhance functional efficacy at M(4) receptors for 13e and 18b. Moreover, compound 1 exhibited antipsychotic activity as assessed by reversal of apomorphine-induced sensory motor gating deficits, suggesting potential utility in the treatment of schizophrenia.

Abstract
We report the discovery and the synthesis of novel, potential antipsychotic compounds combining potent dopamine D2 receptor antagonist and serotonin 5-HT1A receptor agonist properties in the same molecule. We describe the structure-activity relationship that lead us to the promising derivative: N-[(2,2-dimethyl-2,3-dihydro-benzofuran-7-yloxy)ethyl]-3-(cyclopent-1-enyl)-benzylamine 16. The latter has high affinity for D2 and 5-HT1A receptors, whereas it possesses only a weak affinity for 5-HT2A sites. In cellular models of signal transduction, 16 behaves as a silent antagonist at rD2 receptors while activating h5-HT1A receptors with an efficacy at least equivalent to that of the prototypical 5-HT1A agonist (+/-)-8-OH-DPAT. These dual actions confer a unique pharmacological profile to the product. In a behavioral model predictive of positive symptoms, 16 has an activity comparable to that of the typical antipsychotic haloperidol, while it is devoid of cataleptogenic effects. Although it produces behaviors characteristic of 5-HT1A receptor activation in rats, these occur at doses 100 times higher than those with (+/-)-8-OH-DPAT. We believe that the relative balance of D2 and 5-HT1A actions in 16 is appropriate, possibly optimal, to ensure superior efficacy and tolerability over existing antipychotic drugs.

Abstract
(-)-4-Amino-2-thiabicyclo-[3.1.0]hexane-4,6-dicarboxylate (LY389795, (-)-3) is a highly potent and selective agonist of metabotropic glutamate receptors 2 (mGlu2) and 3 (mGlu3). As part of our ongoing research program, we have prepared S-oxidized variants of (-)-3, compounds (-)-10, (+)-11 (LY404040), and (-)-12 (LY404039). Each of these chiral heterobicyclic amino acids displaced specific binding of the mGlu2/3 receptor antagonist 3H-2S-2-amino-2-(1S,2S-2-carboxycycloprop-1-yl)-3-(xanth-9-yl)propanoic acid (3H-LY341495) from membranes expressing recombinant human mGlu2 or mGlu3 and acted as potent agonists in cells expressing these receptor subtypes. Docking of the most potent of these derivatives, (+)-11, to mGlu2 revealed the possibility of an additional H-bond interaction between the sulfoxide oxygen of (+)-11 with tyrosine residue Y236. Pharmacokinetic analysis of mGlu active enantiomers (+)-11 and (-)-12 in rats showed each to be well absorbed following oral administration. Consistent with their mGlu2/3 agonist potency and pharmacokinetic properties, both (+)-11 and (-)-12 blocked phencyclidine-evoked ambulations in a dose-dependent manner, indicating their potential as nonclassical antipsychotic agents.

Abstract
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) receptor antagonists and in addition were highly active as serotonin reuptake inhibitors. Some key representatives showed potent pharmacological in vivo activities after oral dosing in both the antagonism of apomorphine-induced climbing and the potentiation of 5-HTP-induced behavior in mice. On the basis of the preclinical data, 8-{4-[3-(5-fluoro-1H-indol-3-yl)propyl]piperazin-1-yl}-4H-benzo[1,4]oxazin-(R)-2-methyl-3-one (45c, SLV314) was selected for clinical development. In vitro and in vivo studies revealed that 45c has favorable pharmacokinetic properties and a high CNS-plasma ratio. Molecular modeling studies showed that the bifunctional activity of 45c can be explained by its ability to adopt two different conformations fitting either the dopamine D(2) receptor pharmacophore or the serotonin transporter pharmacophore.

Abstract
Neurotensin (NT) and its active fragment NT(8-13) elicit behavioral responses typical of clinically used antipsychotic drugs when administered directly to the brain. However, limited peptide stability and oral bioavailability have prevented these compounds from being developed as relevant pharmaceuticals. Recently, our laboratory designed and studied a first-generation NT(8-13) derivative, KK13, that elicited key pharmacokinetic and behavioral responses typical of clinically used antipsychotic drugs when administered to rats parenterally. This compound was the basis for the rational design of a series of second-generation NT(8-13) analogues (KH1-KH30) studied in this paper. Initial screening of these analogues for CNS activity by monitoring hypothermia induction after peripheral administration defined several compounds (KH11, KH24, KH26, and KH28-KH30) that warranted further investigation. Each compound maintained binding affinity for NTR(1), however, only KH24, KH26, and KH28 (as well as KK13) elicited significant hypothermic responses after oral administration. Of these, KH28 demonstrated an oral activity 3-fold greater than any other analogue; hence it was further characterized in a series of rat behavioral assays. KH28 attenuated d-amphetamine induced hyperlocomotion, a hallmark of current clinically effective antipsychotic drugs, after both IP and oral administration. In addition, tolerance to the compound did not develop after repeated daily dosing, as measured by hypothermic induction as well as attenuation of d-amphetamine induced hyperlocomotion. Finally, KH28 did not produce catalepsy, a deleterious side-effect elicited by classical antipsychotic drugs. KH28 is considered to be an ideal compound for further development as a potential novel antipsychotic.

Abstract
A series of novel tetracyclic tetrahydrofuran derivatives was prepared and evaluated for its potential psychotropic properties. In vitro affinities for multiple dopaminergic, serotonergic, alpha-adrenergic, and histamine receptors and for the norepinephrine transporter as well as the ED(50) values obtained in some in vivo assays for antipsychotic, anxiolytic, and antidepressant potential are reported. Compounds (-)-1, (-)-8d, and (+)-8d have been identified as potential broad-spectrum psychotropic agents.

Abstract
Recent advances in molecular biology suggest that neuronal nicotinic acetylcholine receptors play important roles in the central nervous system (CNS). Of these receptors, the alpha7 group has recently attracted interest for its CNS-related actions and is looked to as a potential new class of pharmacological targets for cognition, schizophrenia, sensory gating, and anxiety. In the course of a research program aimed at the discovery of alpha7 receptor agonists with high affinity, subtype selectivity, and good pharmacokinetic profile, we discovered (R)-3'-(5-chlorothiophen-2-yl)spiro-1-azabicyclo[2.2.2]octane-3,5'-[1',3']oxazolidin-2'-one (25). Compound 25 has potent binding affinity (K(i) = 9 nmol/L) and good selectivity toward the other nicotinic subtypes (alpha4beta2 and alpha1beta2gammadelta) and has been found in pharmacokinetic evaluation to have good oral bioavailability and brain permeability.

Abstract
This report describes the discovery of the first centrally active allosteric modulators of the metabotropic glutamate receptor subtype 5 (mGluR5). Appropriately substituted N-(1,3-diphenyl-1H-pyrazol-5-yl)benzamides (e.g., 8) have been identified as a novel class of potent positive allosteric modulators of mGluR5 that potentiate the response to glutamate. An iterative analogue library synthesis approach provided potentiators with excellent potency and selectivity for mGluR5 (vs mGluRs 1-4, 7, 8). Compound 8q demonstrated in vivo proof of concept in an animal behavior model where known antipsychotics are active, supporting the development of new antipsychotics based on the NMDA hypofunction model for schizophrenia.

Abstract
A series of analogues related to picobenzide (CAS 51832-87-2) have been prepared and have been used as starting material to obtain new trisubstituted oxazole derivatives. Two compounds showed a promising pharmacological profile in screening tests of antipsychotic activity, since they affected apomorphine-induced hyperactivity without significant effects on stereotypies.

Abstract
Elevation of glycine levels and activation of the NMDA receptor by inhibition of the glycine transporter 1 (GlyT-1) is a potential strategy for the treatment of schizophrenia. A novel series of GlyT-1 inhibitors have been identified containing the 2-arylsulfanyl-phenylpiperazine motif. The most prominent member of this series, (R)-4-[5-chloro-2-(4-methoxy-phenylsulfanyl)-phenyl]-2-methyl-piperazin-1-yl-acetic acid (31) is a potent glycine transporter-1 inhibitor (IC(50)=150 nM), which elevated glycine levels in rat ventral hippocampus as measured by microdialysis in vivo at doses of 1.2-4.6 mg/kg s.c.

Abstract
Using rational drug design to develop atypical antipsychotic drug candidates, we generated novel and metabolically stable pyrrolobenzazepines with an optimized pK(i) 5-HT(2A)/D(2) ratio. 5a, obtained by a new palladium-catalyzed three-step synthesis, was selected for further pharmacological and biochemical investigations and showed atypical antipsychotic properties in vivo. 5a was active on conditioned avoidance response at 0.56 mg/kg, it had low cataleptic potential and proved to be better than ST1899, clozapine, and olanzapine, representing a new clinical candidate.

Abstract
A series of (R)- and (S)-3-aminomethyl-1-tetralones, conformationally constrained analogues of haloperidol, have been obtained by enzymatic resolution of the corresponding racemic 3-hydroxymethyl-1-tetralones using Pseudomonas fluorescens lipase. Their binding affinities at dopamine D(2) and serotonin 5-HT(2A) and 5-HT(2C) receptors were determined showing in some cases an atypical antipsychotic profile with Meltzer's ratio higher than 1.30.

Abstract
A number of 5-phenyl-1, 2, 3, 4, 5, 6-hexahydro-azepino-[4, 5-b]indoles 3 were synthesized with different substituents at the azepine-N position (methyl-, allyl-, 2-phenyl-ethyl-, cyclopropylmethyl- and unsubstituted). Furthermore, the indole-N-methylated compound was generated and by using norephedrines and norpseudoephedrines as a chiral pool, 4-methyl-5-phenyl-1, 2, 3, 4, 5, 6-hexahydro-azepino-[4, 5-b]indoles were prepared which contained racemisation at the reacting C-atom. These compounds, as well as the ring-open amino-alcohols, were screened for their affinity to the hD(1)-, hD(5)-, hD(2L)-, and hD(4)-receptors (ç please check sentence). They had micromolar affinities for the receptors and showed the highest affinity to the D(1)-subtype family. The cyclic compounds possessed the highest affinity, with the cyclopropylmethyl-(3c) and methyl-substituents (3 e) being the most active of the tested compounds. Based on an intracellular cAMP-assay, the unsubstituted compound (at the azepine-N position) turned out to be an agonist for the D(1)-and D(5)-subtype family, whereas the substituted compounds showed (partial) agonistic, or even inverse agonistic activity.
