AB  - Serotonin receptors modulate numerous behavioral and neuropsychological processes.
Therefore, they are the target for the action of many drugs, such as antipsychotics, antidepressants,
antiemetics, migraine remedies, and many others. The 5-HT1A receptors have been involved in the
pathogenesis and treatment of anxiety and depression and represent a promising target for new
drugs with reduced extrapyramidal side effects. In most antidepressants, a piperazine-based structural
motif can be identified as a common moiety. Here we describe the synthesis, pharmacological,
and in silico characterization of a novel arylpiperazines series with excellent 5-HT1A affinity. The
final compounds, 4a, 8a, and 8b, were selected according to predictions of in silico pharmacokinetics,
docking analysis, and molecular dynamics in conjunction with physical properties, and metabolic
stability. The accentuated molecules could serve as a lead compound for developing 5-
HT1A drug-like molecules for depression treatment.

AB  - Fourteen novel N-benzylpiperidine and N,N-diarylpiperazine conjugates were synthesized and pharmacologically evaluated as donepezil analogs, in a ligand-based drug design approach. All compounds possessed high to moderate in vitro inhibitory activity with IC50 in range 2.3–20 µM and selectivity towards acetylcholinesterase, while being inactive towards butyrylcholinesterase. Structure-activity relationship analysis revealed the influence of N,N-diarylpiperazine moiety and the linker connecting two pharmacophores on the inhibitory activity. Kinetic studies on the two most active compounds 7g and 8g (IC50 = 2.3 and 4 µM, respectively) revealed mixed type mode of inhibition, binding to both, free enzyme and enzyme-substrate complex. For further understanding of mechanism of action and binding orientations, molecular docking was performed for all compounds, while the ligand transport simulation and molecular dynamics simulations were performed for 7g and 8g. Computational results corroborated well with in vitro activities and kinetic studies.

AB  - Adrenergic receptors are among the most studied G protein-coupled receptors. Activation or blockade of these receptors is a major therapeutic approach for the treatment of numerous disorders such as cardiac hypertrophy, congestive heart failure, hypertension, angina pectoris, cardiac arrhythmias, depression, benign prostate hyperplasia, anaphylaxis, asthma, and hyperthyroidism. Among all nine cloned adrenoceptor subtypes and the subsequent development of animal models, a significant target for various neurological conditions treatment is alpha1-adrenergic receptors. 2-{[4-(2-Methoxyphenyl)piperazin-1-yl]alkyl}-1H-benzo[d]imidazoles, their 5 substituted derivatives, and structurally similar, arylpiperazine based alpha1-adrenergic receptors antagonists (trazodone, naftopidil, and urapidil) have been subjects of comparative analysis. Most of the novel compounds showed alpha1-adrenergic affinity in the range from 22 nM to 250 nM. The in silico docking and molecular dynamics simulations, binding data together with absorption, distribution, metabolism, and excretion (ADME) calculations identified the promising lead compounds. The results brought out the conclusions which allowed us to propose a rationale for the activity of these molecules and to highlight six compounds (2-5, 8, and 12) that exhibited an acceptable pharmacokinetic profile to the advanced investigation as the potential alpha1-adrenergic receptor antagonists.

AB  - Lipophilicity and ionization constant of sixteen fentanyl analogues were investigated by reversed-phase thin-layer chromatography (RP-TLC). Fourteen compounds have nitrogen containing groups at C-3 position of the piperidine ring and two compounds are 3-carbomethoxy derivatives of fentanyl. Among them, five are diastereomeric cis/trans couples and six novel trans diastereomers. In addition, the lipophilicity and ionization constant of fentanyl were also determined by the same method, as a reference. The physicochemical property, lipophilicity, expressed as retention indices RM0, b, and C0, as well as PC1, was determined and correlated with in silico values. Ionization constants were determined on the basis of the relationships between analyte's retention expressed as RF and mobile phase pH. Calculated structural descriptors together with the retention indices, were subjected to the principal component analysis – PCA and hierarchical cluster analysis – HCA, in order to provide basic insights into the similarities among the studied compounds. The blood – brain barrier (BBB) permeation was investigated in the function of experimentally obtained values of lipophilicity, polar surface area and molecular weight. In general, results of the present research corroborate well with previously determined antinociceptive activities of the investigated compounds, pointing out that besides the cis/trans isomerism, another set of important parameters should be taken into account when designing new derivatives of C-3 substituted fentanyl, especially lipophilicity, voluminosity and HBD/A character of the substituents. Accordingly, RP-TLC can be considered as a valuable asset in the ligand-based drug design.

abstract = "Lipophilicity and ionization constant of sixteen fentanyl analogues were investigated by reversed-phase thin-layer chromatography (RP-TLC). Fourteen compounds have nitrogen containing groups at C-3 position of the piperidine ring and two compounds are 3-carbomethoxy derivatives of fentanyl. Among them, five are diastereomeric cis/trans couples and six novel trans diastereomers. In addition, the lipophilicity and ionization constant of fentanyl were also determined by the same method, as a reference. The physicochemical property, lipophilicity, expressed as retention indices RM0, b, and C0, as well as PC1, was determined and correlated with in silico values. Ionization constants were determined on the basis of the relationships between analyte's retention expressed as RF and mobile phase pH. Calculated structural descriptors together with the retention indices, were subjected to the principal component analysis – PCA and hierarchical cluster analysis – HCA, in order to provide basic insights into the similarities among the studied compounds. The blood – brain barrier (BBB) permeation was investigated in the function of experimentally obtained values of lipophilicity, polar surface area and molecular weight. In general, results of the present research corroborate well with previously determined antinociceptive activities of the investigated compounds, pointing out that besides the cis/trans isomerism, another set of important parameters should be taken into account when designing new derivatives of C-3 substituted fentanyl, especially lipophilicity, voluminosity and HBD/A character of the substituents.

AB  - 5HT1A receptor targeting drugs have been used as the treatment for the many neuropsychiatric
disorders, such as schizophrenia and depression. As a part of ongoing research, we designed series of
new compounds that share arylpiperazine common structural motif with the 5HT1A receptor ligand
aripiprazole. Receptor-ligand interactions were determined by the molecular docking simulations,
revealing the positive impact of the phenyl substitution in the arylpiperazine part of the molecules. Nine
selected compounds were synthesized in four reaction steps in high overall yields (59-73%). In vitro
pharmacological evaluation of the synthesized compounds revealed three compounds (5b, 6b and 6c)
with high 5HT1A binding affinity, comparable with aripiprazole (Ki 12.0, 4.8, 12.8, 5.6 nM,
respectively). Compounds from b series, 5b and 6b, possess 2-methoxyphenyl substituents, while 6c
possess 2,3-dichlorophenyl substituent in the arylpiperazine part of the molecule. The pharmacological
results are therefore in accordance with the molecular docking simulations thus proving the rational
design. Compounds 5c, 6b and 6c can be considered as the candidates for further evaluation as new,
potential antidepressants.

AB  - Monoamine oxidases (MAOs) play a key role in the metabolism of major monoamine neurotransmitters. In particular, the upregulation of MAO-B in Parkinson's disease, Alzheimer's disease and cancer augmented the development of selective MAO-B inhibitors for diagnostic and therapeutic purposes, such as the anti-parkinsonian MAO-B irreversible binder L-deprenyl (Selegiline®). Herein we report on the synthesis of novel fluorinated indanone derivatives for PET imaging of MAO-B in the brain. Out of our series, the derivatives 6, 8, 9 and 13 are amongst the most affine and selective ligands for MAO-B reported so far. For the derivative 6-((3-fluorobenzyl)oxy)-2,3-dihydro-1H-inden-1-one (6) exhibiting an outstanding affinity (Ki MAO-B = 6 nM), an automated copper-mediated radiofluorination starting from the pinacol boronic ester 17 is described. An in vitro screening in different species revealed a MAO-B region-specific accumulation of [18F]6 in rats and piglets in comparison to L-[3H]deprenyl. The pre-clinical in vivo assessment of [18F]6 in mice demonstrated the potential of indanones to readily cross the blood–brain barrier. Nonetheless, parallel in vivo metabolism studies indicated the presence of blood–brain barrier metabolites, thus arguing for further structural modifications. With the matching analytical profiles of the radiometabolite analysis from the in vitro liver microsome studies and the in vivo evaluation, the structure's elucidation of the blood–brain barrier penetrant radiometabolites is possible and will serve as basis for the development of new indanone derivatives suitable for the PET imaging of MAO-B.

AB  - Background 4-Anilidopiperidine class of synthetic opioid analgesics, with it’s representative fentanyl, are by far the most potent and clinically significant for the treatment of the severe chronic and surgical pain. However, side effects of μ-opioids are often quite serious. In order to improve the pharmacological profile of this class of opioid analgesics, a novel fentanyl analogs were designed, synthesized and evaluated in vivo for their antinociceptive activity.
Methods The title compounds were prepared using known synthetic transformations, including N-bromoacetamide mediated Hofmann rearrangement, highly selective carbamate cleavage with trimethylsilyl iodide and dehydration of carboxamide group to nitrile in the presence of SOCl2. The antinociceptive activity of the synthesized compounds was determined by tail-immersion and formalin test.
Results The scalable synthetic route towards novel fentanyl analogs bearing nitrogen groups in position C3 of piperidine ring is designed. In addition, Hofmann rearrangement was substantially improved for the more efficient synthesis of previously published 3-substituted fentanyl analogs. The series of ten fentanyl analogs was tested in vivo for their antinociceptive activity. The most potent compound of the series was found to be cis-4, based on the determined ED50 values in tail-immersion test.
Conclusion Of ten compounds tested for their antinociceptive activity, compound cis-4 is characterized by high potency, rapid beginning and short duration of action and due to this might be incorporated in different pharmaceutical forms.

AB  - Background 4-Anilidopiperidine class of synthetic opioid analgesics, with it’s representative fentanyl, are by far the most potent and clinically significant for the treatment of the severe chronic and surgical pain. However, side effects of μ-opioids are often quite serious. In order to improve the pharmacological profile of this class of opioid analgesics, a novel fentanyl analogs were designed, synthesized and evaluated in vivo for their antinociceptive activity.Methods The title compounds were prepared using known synthetic transformations, including N-bromoacetamide mediated Hofmann rearrangement, highly selective carbamate cleavage with trimethylsilyl iodide and dehydration of carboxamide group to nitrile in the presence of SOCl2. The antinociceptive activity of the synthesized compounds was determined by tail-immersion and formalin test.Results The scalable synthetic route towards novel fentanyl analogs bearing nitrogen groups in position C3 of piperidine ring is designed. In addition, Hofmann rearrangement was substantially improved for the more efficient synthesis of previously published 3-substituted fentanyl analogs. The series of ten fentanyl analogs was tested in vivo for their antinociceptive activity. The most potent compound of the series was found to be cis-4, based on the determined ED50 values in tail-immersion test.Conclusion Of ten compounds tested for their antinociceptive activity, compound cis-4 is characterized by high potency, rapid beginning and short duration of action and due to this might be incorporated in different pharmaceutical forms.

AB  - Herein, the synthesis and pharmacological evaluation of 13 novel compounds, designed as potential heterobivalent ligands for μ-opioid receptor (MOR) and dopamine D2 receptors (D2DAR), are reported. The compounds consisted of anilido piperidine and N-aryl piperazine moieties, joined by a variable-length methylene linker. The two moieties represent MOR and D2DAR pharmacophores, respectively. The synthesis encompassed four steps, securing the final products in 28–42 % overall yields. The approach has a considerable synthetic potential, providing access to various related structures. Pharmacological tests involved in vitro competitive assay for D2DAR using [3H] spiperon, as a standard radioligand, and in vivo antinociceptive tests for MOR. The measured dopamine affinities were modest to low, while antinociceptive activity was completely absent. Therefore, the compounds of the general structure prepared in this research are unlikely to be useful as opioid–dopamine receptor heterobivalent ligands.

AB  - Herein, we report on the synthesis and pharmacological evaluation of ten novel fluorinated cinnamylpiperazines as potential monoamine oxidase B (MAO-B) ligands. The designed derivatives consist of either cinnamyl or 2-fluorocinnamyl moieties connected to 2-fluoropyridylpiperazines. The three-step synthesis starting from commercially available piperazine afforded the final products in overall yields between 9% and 29%. An in vitro competitive binding assay using l-[3H]Deprenyl as radioligand was developed and the MAO-B binding affinities of the synthesized derivatives were assessed. Docking studies revealed that the compounds 8–17 were stabilized in both MAO-B entrance and substrate cavities, thus resembling the binding pose of l-Deprenyl. Although our results revealed that the novel fluorinated cinnamylpiperazines 8–17 do not possess sufficient MAO-B binding affinity to be eligible as positron emission tomography (PET) agents, the herein developed binding assay and the insights gained within our docking studies will certainly pave the way for further development of MAO-B ligands.

AB  - The aim of this study was to develop highly specific radiofluorinated ligands for quantitative positron emission tomography (PET) imaging of monoamine oxidase-B (MAO-B) in brain. A series of 8 fluoro derivatives of 1-cinnamyl-4-arylpiperazine were synthesized by standard methods of organic synthesis. The affinity of the compounds was determined in a competitive binding assay using L-[3H] deprenyl as radioligand on rat brain homogenates. The KD of the radioligand was determined by homologous competition. An efficient, three-step procedure for the synthesis of the potential MAO-B ligands was developed. A competitive binding assay was established, using L-[3H]deprenyl as the radioligand, and rat brain membrane homogenate. The compounds were screened (three concentrations 10-9, 10-7 and 10-5) for their MAO-B affinity. We successfully synthesized a series of fluorinated MAO-B ligands. Unfortunately, their affinities toward MAO-B have proved to be rather low. To increase the affinity further modifications are needed.

AB  - A scalable, cost-efficient and simple synthetic pathway towards potential bivalent opioid/dopamine receptor ligands was developed and optimized. Three novel compounds that contain both opioid and dopamine pharmacophores linked by the four methylene group chain were synthesized in 33, 35 and 39 % overall yield after a four-step synthetic route starting from three commercially available N-aryl piperazines. The anilino piperidine precursor was easily prepared in three steps, as previously published, starting from 4- piperidone. The synthesis presented in this paper could be of interest for heterocyclic and general organic chemistry. The newly designed compounds possessing two pharmacophores, opioid and D2/D3, are potentially useful pharmacological probes. Of particular interest would be the simultaneous binding to both opioid and D2/D3 receptors, and the resulting pharmacological responses may be useful for the further understanding of tolerance and dependence phenomena in opioid clinical use and/or abuse.

AB  - Serotonin 5HT1a receptor belongs to a class of G-protein coupled receptors. It serves as a
potential target for neurological disorders such as depression, anxiety etc. It is a well-known
fact that N-arylpiperazine moiety is present in compounds with pronounced 5HT1a activity.
Taking into account previously published results1 novel structures of N-{4-[2-(4-
arylpiperazin-1-yl)ethyl]phenyl}arylamides (Figure 1.) were designed for target synthesis.
Proposed modifications include: different position of hydroxyl group in aryl amide part of
molecule and addition of methoxy and chloro substituents to the phenyl ring of parent
compounds, since their introduction in the molecule leads to increased receptor affinity.
New compounds were synthesized by acylation of N-arylpiperazines using 4-
nitrophenylacetic acid. Obtained amides were converted in 1-(4-nitrophenethyl)-4-
arylpiperazines using diborane in THF. Reduction of nitro compounds by Ra/Ni provided 1-
(4-aminophenethyl)-4-arylpiperazines. Target arylamides were obtained by condensation 1-
(4-aminophenethyl)-4-arylpiperazines with corresponding aryl acids in presence of
propylphosphoric acid anhydride (PPAA) in DMF.
All newly synthesized compounds were evaluated for their activity toward 5HT1a receptors
by in vitro competitive displacement assay of [3H] 8-OH-DPAT. HEK cell line were used as a
source of 5HT1a receptors.
Introduction of 2-methoxy and 2,3-dichloro groups,as well as meta and para hydroxyl group
in molecule resulted in increment of affinity toward 5HT1a receptors comparing to the parent
compounds.

AB  - A total of 14 novel arylpiperazines were synthesized, and pharmacologically evaluated by measuring their affinities towards the D2 dopamine receptor (D2DR) in a [3H]spiperone competition assay. All herein described compounds consist of a benzimidazole moiety connected to the N-(2-methoxyphenyl)piperazine via linkers of various lengths. Molecular docking analysis and molecular dynamics simulations were performed on D2DR-arylpiperazine complexes with an
objective to explore the receptor-ligand interactions and properties of the receptor binding site. Crystal structure of D2DR that has been published recently was used throughout this study.
The major finding is that high affinity arylpiperazines must interact with both the orthosteric binding site and the extended binding pocket of D2DR and thereforeshould contain a linker of 5 or 6 methylene groups long.

AB  - Reversed-phase thin-layer chromatography and micellar thin-layer chromatography were used in order to investigate retention behaviour and to determine lipophilicity of series of 2(methoxy)phenylpiperazine dopamine D2 ligands with different size, shape and rigidity. The retention mechanism was discussed. The lipophilicity parameters obtained in conventional reversed-phase systems expressed as RM0 and C0, as well as RM values
determined in microemulsion reversed-phase systems were correlated with in silico determined lipophilicity values. In silico pharmacokinetic properties of 2-(methoxy)phenylpiperazine dopamine D2 ligands revealed the importance of experimentally determined lipophilicity values besides the molecular weight, on the blood–brain barrier permeability process. Also, the experimentally determined lipophilicity was found as a very important factor in plasma protein binding process of 2-(methoxy)phenylpiperazine dopamine D2 ligands. Besides, the Lipinski's rule of five indicates that examined ligands satisfy the criterion of drug-like molecules. The principal component analysis was performed on the experimentally determined and calculated lipophilicity values as well on the molecular descriptors which describe the pharmacokinetic properties in order to provide basic insights into similarities among the studied ligands.

AB  - Lerimazoline is a sympathomimetic drug that belongs to the imidazoline class of compounds, and is used as a nasal decongestant. Studies on lerimazoline are rare, and its pharmacological profile is not completely understood. Here, we analyzed the affinity of lerimazoline for dopamine receptor D2, serotonin 5-HT1A and 5-HT2A receptors and alpha(1)-adrenoceptor, and investigated lerimazoline contractile effects in isolated rat thoracic aorta. We also determined the effect of several antagonists on the contractile response to lerimazoline, including prazosin (alpha(1)-adrenoceptor antagonist), RX 821002 and rauwolscine (alpha(2)-adrenoceptor antagonists), JP 1302 (alpha(2C)-adrenoceptor antagonist), methiothepin (non-selective 5-HT receptor antagonist), SB 224289 (5-HT1B receptor antagonist), BRL 15572 (5-HT1D receptor antagonist), and ketanserin (5-HT2A receptor antagonist). Lerimazoline displayed high affinity for the 5-HT1A receptor (Ki = 162.5 nM), similar to the previously reported affinity for the 5-HT1D receptor. Binding affinity estimates (Ki) for alpha(1), 5-HT2A, and D-2 receptors were 6656, 4202 and 3437.5 nM, respectively (the literature reported Ki for 5-HT1B receptor is 3480 nM). Lerimazoline caused concentration-dependent contractions in 70% of preparations, varying in the range between 40% and 55% of the maximal contraction elicited by phenylephrine. While prazosin reduced the maximum contractile response to lerimazoline, rauwolscine showed a non-significant trend in reduction of the response. Both ketanserin (10 nM and 1 mu M) and methiothepin strongly suppressed the maximum response to lerimazoline. Overall, our results suggest that 5-HT2A and, less distinctly, alpha(1)-adrenergic receptors are involved in the lerimazoline-induced contractions, which makes lerimazoline an "atypical" decongestant.

AB  - Sixteen new 1-(2-methoxyphenyl)-4-(1-phenethylpiperidin-4-yl)piperazines and 1-(2-methoxyphenyl)-4-[(1-phenethylpiperidin-4-yl)methyl]piperazines were synthesized to be used as probes for mapping the dopamine D-2 receptor (D(2)DAR) arylpiperazine binding site. All compounds were evaluated for their affinity toward D(2)DAR in an in vitro competitive displacement assay. The most active one was 1-(2-methoxyphenyl)-4-{[1-(3-nitrophenethyl)piperidin-4-yl]methyl}piperazine (25) with an affinity of K-i = 54 nM. Docking analysis was conducted on all herein described compounds, whereas molecular dynamic simulation was performed on ligand 25 to establish its mode of interaction with D(2)DAR. Two possible docking orientations are proposed; the one with a salt bridge between the piperidine moiety and Asp114 of D(2)DAR is more stable.
