Evaluation of hypoglycemic effects of 4-thiazolidinones

Nicotinic acid, a well-known hypolipidemic drug, is known to produce elevation of blood glucose in humans. In an earlier study in our laboratory, a thiazolidinone derivative of nicotinic acid was shown to exert hypolipidemic effect. The present study was aimed to find out if this compound produced any elevation of blood glucose in normal and diabetic Wistar rats. A closely related thiazolidinone was also evaluated. The two compounds reduced blood glucose in both normal and diabetic rats, while nicotinic acid produced hyperglycemia. The thiazolidinone structure with its hypoglycemic potential may be opposing the glucose elevating effect of nicotinoyl moiety. It is concluded from the study that the thiazolidinone derivative of nicotinic acid is a hypoglycemic agent besides being hypolipidemic. Detailed investigation is warranted.

Dietary antioxidants prevent alcohol-induced ciliary dysfunction

Previously we have shown that chronic alcohol intake causes alcohol-induced ciliary dysfunction (AICD), leading to non-responsive airway cilia. AICD likely occurs through the downregulation of nitric oxide (NO) and cyclic nucleotide-dependent kinases, protein kinase G (PKG) and protein kinase A (PKA). Studies by others have shown that dietary supplementation with the antioxidants N-acetylcysteine (NAC) and procysteine prevent other alcohol-induced lung complications. This led us to hypothesize that dietary supplementation with NAC or procysteine prevents AICD. To test this hypothesis, C57BL/6 mice drank an alcohol/water solution (20% w/v) ad libitum for 6 weeks and were concurrently fed dietary supplements of either NAC or procysteine. Ciliary beat frequency (CBF) was measured in mice tracheas, and PKG/PKA responsiveness to beta-agonists and NOx levels were measured from bronchoalveolar lavage (BAL) fluid. Long-term alcohol drinking reduced CBF, PKG and PKA responsiveness to beta-agonists, and lung NOx levels in BAL fluid. In contrast, alcohol-drinking mice fed NAC or procysteine sustained ciliary function and PKG and PKA responsiveness to beta-agonists. However, BAL NO levels remained low despite antioxidant supplementation. We also determined that removal of alcohol from the drinking water for as little as 1 week restored ciliary function, but not PKG and PKA responsiveness to beta-agonists. We conclude that dietary supplementation with NAC or procysteine protects against AICD. In addition, alcohol removal for 1 week restores cilia function independent of PKG and PKA activity. Our findings provide a rationale for the use of antioxidants to prevent damage to airway mucociliary functions in chronic alcohol-drinking individuals.

Diastereoselective synthesis of aryloxy phosphoramidate prodrugs of 3′-deoxy-2′,3′-didehydrothymidine monophosphate

The first diastereoselective synthesis of aryloxy phosphoramidate prodrugs of 3′-deoxy-2′,3′-didehydrothymidine monophosphate (d4TMP) is reported. In our approach, (S)-4-isopropylthiazolidine-2-thione 1 was used as a chiral auxiliary to introduce the stereochemistry at the phosphorus atom. In the last step of the developed reaction sequence, the nucleoside analogue d4T was introduced to a stereochemically pure phosphordiamidate which led to the formation of the almost diastereomerically pure phosphoramidate prodrugs 8a-d (?95% de). As expected, the individually prepared diastereomers of the phosphoramidate prodrugs showed significant differences in the antiviral activity. Moreover, the difference was strongly dependent on the aryl substituent attached to the phosphoramidate moiety.

Activation of the Nrf2-regulated antioxidant cell response inhibits HEMA-induced oxidative stress and supports cell viability

Oxidative stress due to increased formation of reactive oxygen species (ROS) in target cells of dental resin monomers like 2-hydroxyethyl methacrylate (HEMA) is a major mechanism underlying the disturbance of vital cell functions including mineralization and differentiation, responses of the innate immune system, and the induction of cell death via apoptosis. Although a shift in the equilibrium between cell viability and apoptosis is related to the non-enzymatic antioxidant glutathione (GSH) in HEMA-exposed cells, the major mechanisms of adaptive antioxidant cell responses to maintain cellular redox homeostasis are still unknown. The present study provides insight into the induction of a communicating network of pathways under the control of the redox-sensitive transcription factor Nrf2, a major transcriptional activator of genes coding for enzymatic antioxidants. Here, oxidative stress was indicated by DCF fluorescence in cells after a short exposure (1h) to HEMA, while DHR123 fluorescence significantly increased about 1.8-fold after a long exposure period (24h) showing the formation of hydrogen peroxide (H2O2). The corresponding expression of Nrf2 was activated immediately after HEMA exposure (1h) and remained constant up to 24h. Nrf2-regulated expression of enzymes of the glutathione metabolism (glutathione peroxidase 1/2, glutathione reductase) decreased in HEMA-exposed cells as a result of GSH depletion, and superoxide dismutase expression was downregulated after H2O2 overproduction. However, the expression of Nrf2-controlled enzymatic antioxidants (catalase, peroxiredoxin, thioredoxin 1, thioredoxin reductase, heme oxygenase-1) and the NADPH-regenerating system (glucose 6-phosphate dehydrogenase, transaldolase) was increased. Phenolic tert-butylhydroquinone (tBHQ), a classic inducer of the Nrf2 pathway, reduced oxidative stress and protected cells from HEMA-induced cell death through a shift in the number of cells in necrosis to apoptosis. The expression of Nrf2 and related enzymatic antioxidants downstream was enhanced by tBHQ in parallel. In conclusion, this investigation expanded the detailed understanding of the underlying mechanisms of HEMA-induced oxidative stress, and highlighted the cross-talk and interdependence between various Nrf2-regulated antioxidant pathways as a major adaptive cell response. The current results demonstrate that modulation of the Nrf2-mediated cellular defense response is an effective means for manipulating the sensitivity of cells to dental resin monomers.

Candidate PET Radioligand Development for Neurofibrillary Tangles: Two Distinct Radioligand Binding Sites Identified in Postmortem Alzheimer’s Disease Brain

[18F]THK-523 and [18F]807 are promising radioligands for imaging neurofibrillary tangles (NFTs) with positron emission tomography (PET) in neurodegenerative diseases, such as Alzheimer’s disease (AD) and traumatic brain injury. Although [18F]THK-523 and [18F]T807 are considered high-affinity selective radioligands for NFTs, uncertainty has existed as to whether PET radioligands for imaging NFTs bind to the same molecular site because in vitro assays for ligands binding to NFTs have been lacking. We labeled THK-523 and T807 with tritium to serve as reference radioligands for in vitro binding assays with AD brain homogenates for newly synthesized ligands. With these radioligands, we identified two distinct binding sites for small molecules, one site with high affinity for THK-523 and the other with high affinity for T807. Moreover, binding assays with [3H]PIB confirmed that the two newly identified binding sites are also distinct from the thioflavin-T binding site where all current clinically useful PET radioligands for imaging beta-amyloid plaque bind with high affinity. The two newly identified binding sites are considered to reside on NFTs rather than on beta-amyloid plaques. Furthermore, we applied all three binding assays to a set of newly prepared compounds, based on chain modifications to THK-523. Some compounds with high affinity and selectivity for the THK-523 binding site emerged from this set, including one with amenability to labeling with fluorine-18, namely, ligand 10b.
