The role of metabotropic glutamate receptors in addiction: Evidence from preclinical models

Addiction is a chronic disorder characterised by repeated bouts of drug taking, abstinence and relapse. The addicted state may be in part due to drug-induced neuroadaptations in the mesocorticolimbic and corticostriatal pathways. Recently focus has been on the role of aberrant glutamate transmission and its contribution to the hierarchical control over these systems. This review will expand our current knowledge of the most recent advances that have been made in preclinical animal models that provide evidence that implicate metabotropic glutamate receptors (mGluRs) in contributing to the neuroadaptations pertinent to addiction, as well as the role of Homer proteins in regulating these responses. The recent discovery of receptor mosaics will be discussed which add an additional dimension to the complexity of understanding the mechanism of glutamate mediated behaviours. Finally this review introduces a new area related to glutamatergic responses, namely microRNAs, that may become pivotal in directing our future understanding of how to best target intervention strategies to prevent addictive behaviours.

An Efficient One-Shot Metal-Free Electrophilic Fluorination of 2-Iminothiazolidine-4-one

A highly efficient one-pot method for the synthesis of mono fluorinated thiazolidinone derivatives have been achieved through four component reaction of primary amines, aryl isothiocyanates, ethyl bromoacetate and Selectfluor as electrophilic fluorinating agent. This protocol is practically convenient and offers the advantage of conducting easily handled sequenceof reaction in single reactor with suitable solvent medium. Reaction of primary amines with aryl isothiocyanate access forthiourea formation followed by addition of ethyl bromoacetate afforded the thiazolidinone, further on addition ofSelectfluor provides desired mono fluorinated products in short time with keen reaction procedure.

Synthesis and identification of quinoline derivatives as topoisomerase I inhibitors with potent antipsoriasis activity in an animal model

Psoriasis is a chronic inflammatory and immune-mediated skin disease. Although certain agents have shown clinical success in treating psoriasis, development of safe and effective strategies for the treatment of this condition remains important. Research suggests that DNA topoisomerase I (Topo I)inhibitors may have potent psoriasis-ameliorating effects. Here, 25 quinoline derivatives were synthesized and identified as Topo I inhibitors. These compounds inhibited the 12?O?tetradecanoylphorbol-13-acetate-induced mouse ear inflammation. The most potent analogs, 5i and 5l, suppressed the expression of inflammatory cytokines in lipopolysaccharide-stimulated HaCaT cells. Additionally, the lead compounds significantly improved imiquimod-induced psoriasis-like inflammation in mice. Moreover, the expression levels of cytokines and inflammatory mediators, such as interleukin (IL)-17A, IL-22, IL-23, nuclear factor-kappaB subunit p65, tumor necrosis factor-alpha, and interferon-gamma, were dramatically inhibited in the dorsal skin of 5i- and 5l-treated mice. These findings indicate that the inhibition of Topo I activity may potentially be an effective strategy for psoriasis treatment.

Organocatalytic Cyclization of COS and Propargylic Derivatives to Value-Added Heterocyclic Compounds

The organocatalytic cyclization of propargylic amines/amides with carbonyl sulfide (COS) was firstly achieved by employing COS adducts of Lewis base (LB) as organocatalysts, affording various functionalized 1,3-thiazolidine-2-ones, and 1,3-thiazolidine-2,4-diones derivatives in a highly chemo- and stereoselective manner. The isotope labeling and stoichiometric experiments suggested the LB-COS adducts preferentially mediated basic ionic pair mechanism. Furthermore, the practical application of this methodology was highlighted by the highly efficient synthesis of rosiglitazone using COS as sulfur source.

Synthesis and evaluation of anticonvulsant activities of 5-benzylidene-2-(5-methylisoxazol-3-ylimino)thiazolidin-4-one derivatives

Fifteen new 5-benzylidene-2-(5-methylisoxazol-3-ylimino)thiazolidin-4-one derivatives (4-18) were synthesized and evaluated for their preliminary anticonvulsant activity and neurotoxicity by using the maximal electroshock (MES) and rotarod tests. The structures of synthesized compounds were established by IR,1H NMR,13C NMR and mass spectral data. Among the compounds studied, 5-(3-fluorobenzylidene)-2-(5-methylisoxazol-3-ylimino)thiazolidin-4-one (8) was the most potent compound, with a median effective dose of 43.9 mg/kg and a high protective index (PI) of more than 11.1 after intraperitoneal administration in mice. Compound 8 showed significant oral activity against MES-induced seizures in mice, with an ED50 of 84.2 mg/kg and a PI above 11.8. These results demonstrate that compound 8 is safer than the commercially drugs.

Crystal structures of two 1,3-thiazolidin-4-one derivatives featuring sulfide and sulfone functional groups

The crystal structures of two closely related compounds, 1-cyclohexyl-2-(2-nitrophenyl)-1,3-thiazolidin-4-one, C15H18N2O3S, (1) and 1-cyclohexyl-2-(2-nitrophenyl)-1,3-thiazolidin-4-one 1,1-dioxide, C15H18N2O5S, (2), are presented. These compounds are comprised of three types of rings: thiazolidinone, nitrophenyl and cyclohexyl. In both structures, the rings are close to mutually perpendicular, with interplanar dihedral angles greater than 80 in each case. The thiazolidinone rings in both structures exhibit envelope puckering with the S atom as flap and the cyclohexyl rings are in their expected chair conformations. The two structures superpose fairly well, except for the orientation of the nitro groups with respect to their host phenyl ring, with a difference of about 10 between 1 and 2. The extended structure of 1 has two kinds of weak C – H?O interactions, giving rise to a closed ring formation involving three symmetry-related molecules. Structure 2 has four C – H?O interactions, two of which are exclusively between symmetry-related thiazolidinone dioxide moieties and have a parallel ‘give-and-take-fashion’ counterpart. In the other two interactions, the nitrophenyl ring and the cyclohexane ring each offer an H atom to the two O atoms on the sulfone group. Additionally, a C – H?pi interaction between a C – H group of the cyclohexane ring and the nitrophenyl ring of an adjacent molecule helps to consolidate the structure.

Design, Synthesis and Biological Evaluation of 2-(naphthoyl) iminothiazolidin-4-ones as Potential Anticancer Agents

A library of novel naphthyl bearing 2-iminothiazolidin-4-ones (2-ITZDs) (2 a?2 q) was designed and synthesized through a facile route involving regioselective heterocyclization of unsymmetrical thioureas (1 a?1 q). The synthesis was achieved at ambient temperature in good to excellent yields under catalyst free conditions. The molecular structures of 2-ITZDs were elucidated by spectroscopic techniques such as FT-IR, 1H-NMR and 13C-NMR. X-ray structural data was used to establish the structure (2 o) unequivocally and to define the geometry of exo double bond. The in vitro anticancer activity of 2-ITZDs (2 a?2 q) was investigated in several human cancer cell lines (A549, LNCap, PC-3, MDA-MB-231, BxPC3, MIA PaCa2). All compounds showed cytotoxicity with IC50 values ranging from 6?23 muM in the tested cancer cell lines except MDA-MB-231. Compound 2 k (IC50=7 muM) and the homologous analog 2 q (IC50=6 muM) were found to be equipotent to 2 k and showed moderate cytotoxicity against human breast cell line (DA-MB-231). Furthermore, compound 2 k exhibited a medium permeability, enough metabolic stability and no significant inhibition of hERG channel. Compound 2 k inhibited cytochrome P450 activity below 50 % in 1 A2, 3 A4 and 2 C19, but not in 2 C9 and 2D6 at 10 muM. Structure-activity relationships (SAR) provided useful insights towards this class of compounds and tiled a way to design novel analogues with increased potency.

In Vivo Selective Modulation of Tissue Glutathione in a Rat Mammary Carcinoma Model

Glutathione (GSH) is known to play a role in cellular sensitivity to some chemotherapeutic agents and to radiation. Depletion of cellular GSH has been demonstrated to result in enhanced toxicity of these drugs, and this approach is being explored in the clinic as a form of biochemical modulation, using the drug buthionine sulfoximine (BSO). The fact that some drug-resistant cell lines have increased glutathione levels, and that enhancing GSH concentrations in animal tissues protects against a variety of xenobiotic agents, suggest a different potential approach to improving anti-cancer therapy. We have examined the efficacy of the cysteine “pro-drug” L-2-oxothiazolidine-4-carboxylate (OTZ) at enhancing normal tissue versus tumor GSH. Animals were treated with OTZ or BSO, and the concentrations of GSH in normal tissues and tumor were measured. We found that the presence of the tumor itself decreased bone marrow GSH, but that OTZ significantly increased it in this setting. Interestingly, OTZ administration significantly depleted tumor GSH levels to the same level as did BSO. OTZ could offer a selective biochemical modulation of GSH.
