Computer-aided insights into receptor-ligand interaction for novel 5-arylhydantoin derivatives as serotonin 5-HT7 receptor agents with antidepressant activity

This paper presents a computer-aided insight into the receptor-ligand interaction for novel analogs of the lead structure 5-(4-fluorophenyl)-3-(2-hydroxy-3-(4-(2-methoxyphenyl)piperazin-1-yl)propyl)-5-methylimidazolidine-2,4-dione (1, MF-8), as part of the search for potent and selective serotonin 5-HT7 receptor (5-HT7R) agents. New hydantoin derivatives (4-19) were designed and synthesized. For 5-phenyl-3-(2-hydroxy-3-(4-(2-ethoxyphenyl)piperazin-1-yl)propyl)-5-methylimidazolidine-2,4-dione (4), its crystal structure was determined experimentally. Molecular modeling studies were performed, including both pharmacophore and structure-based approaches. New compounds were investigated in radioligand binding assays (RBA) for their affinity toward 5-HT7R and selectivity over 5-HT1AR, dopamine D2R and α1-, α2-and β-adrenoceptors. Selected compounds (5-8) were assessed for their antidepressant and anxiolytic effects in vivo in mice. Most of the tested compounds displayed potent affinity and selectivity for 5-HT7R in RBA, in particular seven compounds (4, 5, 7, 8 and 10-12, Ki ≤ 10 nM). Antidepressant-like activity in vivo for all tested compounds (5-8) was confirmed. SAR analysis based on both crystallography-supported molecular modeling and RBA results indicated that mono-phenyl substituents at both hydantoin and piperazine are more favorable for 5-HT7R affinity than the di-phenyl ones.

Computer-aided studies for novel arylhydantoin 1,3,5-triazine derivatives as 5-HT6 serotonin receptor ligands with antidepressive-like, anxiolytic and antiobesity action in vivo

This study focuses on the design, synthesis, biological evaluation, and computer-aided structure-activity relationship (SAR) analysis for a novel group of aromatic triazine-methylpiperazines,with an hydantoin spacer between 1,3,5-traizine and the aromatic fragment. New compounds were synthesized and their affinities for serotonin 5-HT6, 5-HT1A, 5-HT2A, 5-HT7, and dopamineD2 receptorswere evaluated. The induced-fit docking (IFD) procedure was performed to explore the 5-HT6 receptor conformation space employing two lead structures. It resulted in a consistent binding mode with the activity data. For the most active compounds found in each modification line, anti-obesity and anti-depressive-like activity in vivo, as well as "druglikeness" in vitro, were examined. Two 2-naphthyl compounds (18 and 26) were identified as themost active 5-HT6R agents within each leadmodification line, respectively. The 5-(2-naphthyl)hydantoin derivative 26, themost active one in the series (5-HT6R: Ki = 87 nM), displayed also significant selectivity towards competitive G-protein coupled receptors (6-197-fold). Docking studies indicated that the hydantoin ring is stabilized by hydrogen bonding, but due to its different orientation, the hydrogen bonds formwith S5.44 and N6.55 or Q6.58 for 18 and 26, respectively. Compound 26 exerted anxiolytic-like and antidepressant-like activities. Importantly, it demonstrated anti-obesity properties in animals fed palatable feed, and did not show toxic effects in vitro.

Synthesis and in vivo hypoglycemic activity of new imidazolidine-2,4-dione derivatives

A series of new 3-arylsulfonylimidazolidine-2,4-diones (2a-2p) were synthesized by reacting imidazolidine-2,4-diones (1a-1e) with arylsulfonyl chlorides in the presence of triethyl amine. The imidazolidine-2,4-diones (1a-1e) were in turn synthesized from the corresponding ketones through Bucherer-Bergs reaction. All the synthesized compounds were characterized on the basis of their spectral (IR, 1H and 13C NMR and MS) and microanalytical data. The hypoglycemic activity of the compounds (2a-2p) was evaluated using alloxanized diabetic rat model. Compound 2a showed an excellent activity with a reduction in the blood glucose level of -286 ± 7 mg/dL after 5 h of drug administration as compared to -270 ± 8 mg/dL for glipizide. The hypoglycemic activity of compound 2b (-268 ± 9 mg/dL) was also comparable to the standard drug. However, only moderate activity was observed for compound 2e.

Design, synthesis and pharmacology of 1,1-bistrifluoromethylcarbinol derivatives as liver X receptor β-selective agonists

A novel series of 1,3-bistrifluoromethylcarbinol derivatives that act as liver X receptor (LXR) β-selective agonists was discovered. Structure-activity relationship studies led to the identification of molecule 62, which was more effective (Emax) and selective toward LXRβ than T0901317 and GW3965. Furthermore, 62 decreased LDL-C without elevating the plasma TG level and significantly suppressed the lipid-accumulation area in the aortic arch in a Bio F1B hamster fed a diet high in fat and cholesterol. We demonstrated that our LXRβ agonist would be potentially useful as a hypolipidemic and anti-atherosclerotic agent. In this manuscript, we report the design, synthesis and pharmacology of 1,3-bistrifluoromethylcarbinol derivatives.

Microwave-promoted facile and rapid synthesis procedure for the efficient synthesis of 5,5-disubstituted hydantoins

A fast, general, environmentally friendly, and facile method for preparation of 5, 5-disubstituted hydantoins from the reaction between ketone (or aldehyde) derivatives with KCN and ammonium carbonate under microwave irradiation is presented. The microwaves remarkably accelerated this reaction, the reaction times decreased dramatically, the reaction conditions were milder, and the yields were also greater. Also a comparative study of microwave versus classical conditions has been done. All the products were characterized by infrared, NMR, and CHN analysis, and their melting points are identical to those of the known compounds reported in the literature. This method might be useful in the future for the preparation of similar derivatives. Taylor & Francis Group, LLC.

A one-pot synthesis of 5,5-disubstituted hydantoin derivatives using magnetic Fe3O4 nanoparticles as a reusable heterogeneous catalyst

A facile and rapid method for the one-pot synthesis of 5,5-disubstituted hydantoins in the presence of magnetic Fe3O4 nanoparticles has been developed. The multicomponent reactions of carbonyl compounds (aldehydes and ketones), potassium cyanide and ammonium carbonate were carried out under solvent-free conditions to obtain various hydantoin derivatives. The magnetic catalyst could be readily separated by an external magnet from the reaction mixture. This procedure has many advantages, such as the use of a reusable magnetic catalyst, high yields, short reaction times, simplicity and very easiness with implementing the methodology.

Solvent effects on the absorption spectra of potentially pharmacologically active 5-alkyl-5-arylhydantoins: A structure-property relationship study

To obtain insight into the interactions of potential anticonvulsant drugs with their surrounding, two series of 5-methyl-5-aryl- and 5-ethyl-5- -arylhydantoins were synthesized and their absorption spectra were recorded in the region from 200 to 400 nm in a set of selected solvents. The effects of solvent dipolarity/polarizability and solvent-solute hydrogen bonding interactions on the absorption maxima shifts were analyzed by means of the linear solvation energy relationship (LSER) concept of Kamlet and Taft. The ratio of the contributions of specific and non-specific solvent-solute interactions were correlated with the corresponding absorption, distribution, metabolism, and excretion (ADME) properties of the studied compounds. The correlation equations were combined with different physicochemical parameters to generate new equations, which demonstrate the reasonable relationships between the solvent- solute interactions and the structure-activity parameters.
