Carbon disulphide absorption during xanthate reagent mixing in a gold mine concentrator. (1/5377)

A xanthate reagent mixer at a gold mine concentrator was exposed to carbon disulphide by extensive skin contamination with xanthate powder and solution during the reagent mixing process. Absorption of carbon disulphide was confirmed by the detection of urinary 2-thiothiazolidine-4-carboxylic acid (TTCA). Drager colorimetric tube testing during subsequent mixing recorded a maximum concentration of at least 60 ppm carbon disulphide. An illness consisting of predominantly gastrointestinal symptoms began 20 h after the exposure. Although this may have been due to carbon disulphide toxicity this is by no means certain. The need for engineering controls, impervious protective clothing and full-face respirators with particulate and organic vapour cartridges is discussed. This episode occurred at another mine site, unrelated to Mount Isa Mines Limited.  (+info)

Acute troglitazone action in isolated perfused rat liver. (2/5377)

1. The thiazolidinedione compound, troglitazone, enhances insulin action and reduces plasma glucose concentrations when administered chronically to type 2 diabetic patients. 2. To analyse to what extent thiazolidinediones interfere with liver function, we examined the acute actions of troglitazone (0.61 and 3.15 microM) on hepatic glucose and lactate fluxes, bile secretion, and portal pressure under basal, insulin- and/or glucagon-stimulated conditions in isolated perfused rat livers. 3. During BSA-free perfusion, high dose troglitazone increased basal (P < 0.01), but inhibited glucagon-stimulated incremental glucose production by approximately 75% (10.0 +/- 2.5 vs control: 40.0 +/- 7.2 micromol g liver(-1), P < 0.01). In parallel, incremental lactate release rose approximately 6 fold (13.1 +/- 5.9 vs control: 2.2 +/- 0.8 mmol g liver(-1), P < 0.05), while bile secretion declined by approximately 67% [0.23 +/- 0.02 vs control: 0.70 +/- 0.05 mg g liver(-1) min(-1)), P < 0.001]. Low dose troglitazone infusion did not enhance the inhibitory effect of insulin on glucagon-stimulated glucose production, but rapidly increased lactate release (P < 0.0005) and portal venous pressure (+0.17 +/- 0.07 vs +0.54 +/- 0.07 cm buffer height, P < 0.0001). 4. These results indicate that troglitazone exerts both insulin-like and non-insulin-like hepatic effects, which are blunted by addition of albumin, possibly due to troglitazone binding.  (+info)

Heparin inhibits proliferation of myometrial and leiomyomal smooth muscle cells through the induction of alpha-smooth muscle actin, calponin h1 and p27. (3/5377)

Mast cells are widely distributed in human tissues, including the human uterus. However, the function of mast cells in uterine smooth muscle has not been clearly established. Mast cells possess secretory granules containing such substances as heparin, serotonin, histamine and many cytokines. To help establish the role of mast cells in the human myometrium, the action of heparin was investigated using smooth muscle cells (SMC) from normal myometrium and from leiomyoma. The proliferation of cultured myometrial and leiomyomal SMC was inhibited by heparin treatment. Flow cytometric analysis showed that the population in the G1 phase of the cell cycle increased under heparin treatment. Western blotting analysis showed that markers of SMC differentiation such as alpha-smooth muscle actin (alpha-SMA), calponin h1 and cyclin-dependent kinase inhibitor p27 were induced by heparin, whereas cell-cycle-related gene products from the G1 phase of the cell cycle, such as cyclin E and cdk2, were not changed. Taken together, these results indicate that heparin inhibits the proliferation of myometrial and leiomyomal SMC through the induction of alpha-SMA, calponin h1 and p27. We suggest that heparin from mast cells may induce differentiation in uterine SMC and may influence tissue remodelling and reconstruction during physiological and pathophysiological events.  (+info)

Latrunculin-A causes mydriasis and cycloplegia in the cynomolgus monkey. (4/5377)

PURPOSE: To determine the effect of latrunculin (LAT)-A, which binds to G-actin and disassembles actin filaments, on the pupil, accommodation, and isolated ciliary muscle (CM) contraction in monkeys. METHODS: Pupil diameter (vernier calipers) and refraction (coincidence refractometry) were measured every 15 minutes from 0.75 to 3.5 hours after topical LAT-A 42 microg (approximately 10 microM in the anterior chamber [AC]). Refraction was measured every 5 minutes from 0.5 to 1.5 hours after intracameral injection of 10 microl of 50 microM LAT-A (approximately 5 microM in AC), with intramuscular infusion of 1.5 mg/kg pilocarpine HCl (PILO) during the first 15 minutes of measurements. Pupil diameter was measured at 1 and 2 hours, and refraction was measured every 5 minutes from 1 to 2 hours, after intravitreal injection of 20 microl of 1.25 mM LAT-A (approximately 10 microM in vitreous), with intramuscular infusion of 1.5 mg/kg PILO during the first 15 minutes of measurements (all after topical 2.5% phenylephrine), and contractile response of isolated CM strips, obtained <1 hour postmortem and mounted in a perfusion apparatus, to 10 microM PILO +/- LAT-A was measured at various concentrations. RESULTS: Topical LAT-A of 42 microg dilated the pupil without affecting refraction. Intracameral LAT-A of 5 microM inhibited miotic and accommodative responses to intramuscular PILO. Intravitreal LAT-A of 10 microM had no effect on accommodative or miotic responses to intramuscular PILO. LAT-A dose-dependently relaxed the PILO-contracted CM by up to 50% at 3 microM in both the longitudinal and circular vectors. CONCLUSIONS: In monkeys, LAT-A causes mydriasis and cycloplegia, perhaps related to its known ability to disrupt the actin microfilament network and consequently to affect cell contractility and adhesion. Effects of LAT-A on the iris and CM may have significant physiological and clinical implications.  (+info)

Mechanism of weight gain suppressing effect of ER-40133, an angiotensin I converting enzyme inhibitor, in growing rats. (5/5377)

Effects of ER-40133, an inhibitor of angiotensin converting enzyme (ACE), on weight gain and sodium and potassium balance were studied in growing SD male rats. Thirty-two animals (seven weeks of age) were divided into two groups; one received a standard diet containing 0.227% sodium and the other a low (0.065%) sodium diet. They were divided into four subgroups; one control group and three treated groups receiving 3, 10 or 30 mg/kg of ER-40133, by gavage, once a day for five consecutive days. Body weight gain (average of the standard and low sodium diet groups) was -32% in the 3 mg/kg group,-74% in 10 mg/kg group and -99% in 30 mg/kg group, when compared with the control group. There was a highly linear correlation between suppression of body weight gain and reduction in sodium and potassium retention for both groups of animals given the standard and low sodium diet. The reduced sodium retention, the primary effect of ACE inhibitors, accounted for about 30% of suppressed weight gain, and the reduced potassium retention, the secondary effect of sodium deficiency, could account for the rest about 70% of weight suppression by ER-40133.  (+info)

p300 interacts with the N- and C-terminal part of PPARgamma2 in a ligand-independent and -dependent manner, respectively. (6/5377)

The nuclear peroxisome proliferator-activated receptor gamma (PPARgamma) activates the transcription of multiple genes involved in intra- and extracellular lipid metabolism. Several cofactors are crucial for the stimulation or the silencing of nuclear receptor transcriptional activities. The two homologous cofactors p300 and CREB-binding protein (CBP) have been shown to co-activate the ligand-dependent transcriptional activities of several nuclear receptors as well as the ligand-independent transcriptional activity of the androgen receptor. We show here that the interaction between p300/CBP and PPARgamma is complex and involves multiple domains in each protein. p300/CBP not only bind in a ligand-dependent manner to the DEF region of PPARgamma but also bind directly in a ligand-independent manner to a region in the AB domain localized between residue 31 to 99. In transfection experiments, p300/CBP could thereby enhance the transcriptional activities of both the activating function (AF)-1 and AF-2 domains. p300/CBP displays itself at least two docking sites for PPARgamma located in its N terminus (between residues 1 and 113 for CBP) and in the middle of the protein (between residues 1099 and 1460).  (+info)

L-764406 is a partial agonist of human peroxisome proliferator-activated receptor gamma. The role of Cys313 in ligand binding. (7/5377)

Insulin-sensitizing thiazolidinedione (TZD) compounds are high affinity ligands for a member of the nuclear receptor family, peroxisome proliferator-activated receptor (PPAR) gamma. A scintillation proximity assay for measurement of 3H-radiolabeled TZD binding to human PPARgamma under homogeneous conditions was developed. Using this approach, a novel non-TZD compound (L-764406) was shown to be a potent (apparent binding IC50 of 70 nM) PPARgamma ligand. Preincubation of PPARgamma with L-764406 prevented binding of the [3H]TZD, suggesting a covalent interaction with the receptor; in addition, structurally related analogues of L-764406, which would be predicted not to interact with PPARgamma in a covalent fashion, did not displace [3H]TZD binding to PPARgamma. Covalent binding of L-764406 was proven by an observed molecular weight shift of a tryptic PPARgamma ligand binding domain (LBD) peptide by mass spectrometric analysis. A specific cysteine residue (Cys313 in helix 3 of hPPARgamma2) was identified as the attachment site for this compound. In protease protection experiments, the liganded receptor adopted a typical agonist conformation. L-764406 exhibited partial agonist activity in cells expressing a chimeric receptor containing the PPARgamma LBD and a cognate reporter gene and also induced the expression of the adipocyte-specific gene aP2 in 3T3-L1 cells. In contrast, L-764406 did not exhibit activity in cells transfected with chimeric receptors containing PPARalpha or PPARdelta LBDs. The partial agonist properties of L-764406 were also evident in a co-activator association assay, indicating that the increased transcription in cells was co-activator mediated. Thus, L-764406 is a novel non-TZD ligand for PPARgamma and is also the first known partial agonist for this receptor. The results suggest a critical functional role for Cys313, and helix 3, in contributing to ligand binding and subsequent agonist-induced conformational changes.  (+info)

Hemodynamic basis for the acute cardiac effects of troglitazone in isolated perfused rat hearts. (8/5377)

Troglitazone is a thiazolidinedione used for the treatment of NIDDM and potentially for other insulin-resistant disease states. Troglitazone has recently been shown to increase cardiac output and stroke volume in human subjects. These actions are thought to be mediated by the reduction of peripheral resistance, but a potential direct effect on cardiac function has not been studied. Therefore, we investigated the direct cardiac hemodynamic effects of troglitazone in isolated perfused rat hearts. Five groups of hearts were studied. Hearts were tested under isovolumetric contraction with a constant coronary flow, and troglitazone (0.2, 0.5, and 1.0 micromol) was administered by bolus injection. Peak isovolumetric left ventricular pressure (LVPmax), peak rate of rise of LVP (dP/dt(max)), and peak rate of fall of LVP (dP/dt(min)) were significantly increased 1 min after troglitazone administration in a dose-dependent manner, while the heart rate (HR) and coronary perfusion pressure (CPP) were significantly decreased (P < 0.05). HR was then fixed by pacing and/or CPP was fixed with nitroprusside to eliminate any effect of the two variables on the action of troglitazone. With constant HR and/or constant CPP, the effect of troglitazone on LVPmax, dP/dt(max), and dP/dt(min) was still unchanged. In addition, the positive inotropic, positive lusitropic, and negative chronotropic actions of troglitazone were not influenced even when hearts were pretreated with prazosin, propranolol, or nifedipine. In conclusion, troglitazone has direct positive inotropic, positive lusitropic, negative chronotropic, and coronary artery dilating effects. The inotropic and chronotropic actions of troglitazone are not mediated via adrenergic receptors or calcium channels. These findings have important clinical implications for diabetic patients with congestive heart failure.  (+info)

Thiazoles and their derivatives have been frequently discovered as a vital component of novel and structurally diverse natural products that exhibit a wide variety of biological activities. The exceptional range of antitumor, antiviral, and antibiotic activities, as well as their presence in peptides, or ability to bind to proteins, DNA, and RNA, have directed numerous synthetic studies and new applications of these heterocycles.The thiazole ring has been identified as a central feature of a myriad of natural products, perhaps the best known being the epothilones. Additionally, thiazoles are frequently appearing in peptide research. Thiazoles can also serve as a protected formyl group that can be liberated in the late stages of a complex natural product synthesis. The presence of a halogen allows these reagents to be used as substrates in various coupling reactions, including Suzuki-Miyaura cross-coupling reactions.Learn More about Thiazoles

5745 Interactions between dual Bcr/Abl and Src inhibitor dasatinib and MEK1/2 inhibitors have been examined in CML cell lines and primary specimens, including those resistant to imatinib mesylate. Co-treatment of K562 or LAMA cells with marginally toxic concentrations of the MEK1/2 inhibitors PD184352 or U0126 and extremely low concentrations of dasatinib (e.g., sub-nanomolar) synergistically potentiated mitochondrial damage, caspase activation, and apoptosis. Similar interactions were observed in CD34+ cells from a CML patient-derived but not in normal human CD34+ bone marrow cells. These interactions were associated with multiple perturbations in survival signaling pathways, including inactivation of Bcr/Abl, STAT5, ERK1/2, down-regulation of Bcl-xL, Mcl-1, and dephosphorylation/activation of BIM. These perturbations were also associated with BAX and BAK translocation, resulting in activation of caspases as well as mitochondrial dysfunction. BIM knockdown by shRNA suppressed both BAX and BAK ...

Objective: The objective of this selective EBM review is to determine whether or not dasatinib improves outcomes and tolerability in patients with chronic myeloid leukemia as compared to imatinib. Study Design: Review of three English language, non-blinded randomized controlled trials from 2009, 2010, and 2010. Data Sources: Randomized, controlled, non-blinded clinical trials comparing dasatinib to imatinib or comparing dasatinib once daily vs dasatinib twice daily, found using the PubMed database. Outcomes measured: Overall survival and progression-free survival were measured at one and two years after initiation of therapy. Safety profiles and incidence of adverse effects were also measured. This is graded on a scale of 1 to 4, from lowest in severity to highest in severity. Additionally, adverse effects were noted as hematologic (neutropenia, anemia, thrombocytopenia) or nonhematologic (fluid retention, diarrhea, vomiting, fever). Results: When comparing dasatinib to imatinib, both drugs provided
Resistance to bacteriostasis by 2-thiazole alanine develops rapidly; however, such resistance is lost during growth in the absence of the analog. This induced resistance is accompanied by increased formation of an enzyme sensitive to 2-thiazole alanine. Maintenance of the elevated enzyme levels in growing cells, like resistance, requires the presence of the analog. ...

Additive antitumor activity of dasatinib and Eto in MDA-MB-231 cells. The cells were treated with indicated concentrations of dasatinib and/or 0.1 μM Eto for t
BACKGROUND: The introduction of specific BCR-ABL inhibitors in chronic myelogenous leukemia therapy has entirely mutated the prognosis of this hematologic cancer from being a fatal disorder to becoming a chronic disease. Due to the probable long lasting treatment with tyrosine-kinase inhibitors (TKIs), the knowledge of their effects on normal cells is of pivotal importance.. DESIGN AND METHODS:. We investigated the effects of dasatinib treatment on human bone marrow-derived mesenchymal stromal cells (MSCs).. RESULTS:. Our findings demonstrate, for the first time, that dasatinib induces MSCs adipocytic differentiation. Particularly, when the TKI is added to the medium inducing osteogenic differentiation, a high MSCs percentage acquires adipocytic morphology and overexpresses adipocytic specific genes, including PPARγ, CEBPα, LPL and SREBP1c. Dasatinib also inhibits the activity of alkaline phosphatase, an osteogenic marker, and remarkably reduces matrix mineralization. The increase of PPARγ is ...

TY - JOUR. T1 - An antidiabetic thiazolidinedione is a high affinity ligand for peroxisome proliferator-activated receptor γ (PPARγ). AU - Lehmann, Jürgen M.. AU - Moore, Linda B.. AU - Smith-Oliver, Tracey A.. AU - Wilkison, William O.. AU - Willson, Timothy M.. AU - Kliewer, Steven A.. PY - 1995/6/2. Y1 - 1995/6/2. N2 - Thiazolidinedione derivatives are antidiabetic agents that increase the insulin sensitivity of target tissues in animal models of non-insulin- dependent diabetes mellitus. In vitro, thiazolidinediones promote adipocyte differentiation of preadipocyte and mesenchymal stem cell lines; however, the molecular basis for this adipogenic effect has remained unclear. Here, we report that thiazolidinediones are potent and selective activators of peroxisome proliferator-activated receptor γ (PPARγ), a member of the nuclear receptor superfamily recently shown to function in adipogenesis. The most potent of these agents, BRL49653, binds to PPARγ with a K(d) of approximately 40 nM. ...
The Quantitative Structure-Activity Relationship of a series of novel Thiazoline derivatives with anticancer activity has been studied by using the density functional theory by B3LYP/ 6-31G. Descriptors of quantum mechanics of 21 thiazoline derivatives with known activity were obtained. Multiple linear regressions were employed to model the relationships between molecular descriptors and biological activity of molecules using stepwise method. The most model shows not only significant statistical quality, but also predictive ability, with the square of adjusted correlation coefficient (R2=0.945) and standard error (SE=0.586). We find that the anticancer activity expressed that as half maximal inhibitory concentration (IC50), closely relates to the highest occupied molecular orbital, dipole moment, softness, hardness, ionization energy, electron affinity. Accordingly can be offered a quantitative model, and interpret the activity of the compounds relying on the multivariate statistical analysis. This

In this study, we compared the effects of the Src inhibitor dasatinib on the urothelial cancer cell line RT112 and its gemcitabine-resistant sub-line RT112rGEMCI20 in cell culture and in an orthotopic bladder cancer xenograft model in mice.. In cell culture, both cell lines displayed similar growth kinetics. Dasatinib inhibited Src phosphorylation in RT112 and RT112rGEMCI20 cells at low nanomolar concentrations similar to those that had already been described to affect Src phosphorylation [9]. While dasatinib had previously been shown to interfere with the phosphorylation of Akt (Thr308 and Ser473) in squamous cell lung cancer [22], we only detected inhibition of phosphorylation of Akt (Thr308). The reasons for this may be the consequence of cell type-specific differences between the investigated models. Although dasatinib exerted similar effects on Src signaling in RT112 and RT112rGEMCI20 cells, its effects on cell viability differed between the two cell lines. The effective concentrations of ...

PY - 2010/8/20. Y1 - 2010/8/20. N2 - In this study, a straight forward route for the synthesis of testosterone succinate-vitamin B1 conjugate and their antibacterial activities on S. aureus, E. coli and K. pneumoniae are reported. This first step was achieved by reacting 3-[(4-amino-2-methyl-5-pyrimidinyl)methyl]-5- (2-hydroxyethyl)-4-methylthiazolium chloride (vitamin B1) with testosterone- succinate resulting in amide bond formation. The results showed that the 1H NMR spectra of the testosterone succinate-vitamin B1 conjugate shows upfield shifts at 0.80 and 1.19 ppm for methyls present in the heterocyles rings at 3.18 and 3.90 ppm for methylenes of the hydroxietilen moiety bonded to thiazol ring. The hydrogens of the methylene between the pyrimidine and thiazol rings appears at 5.68 ppm. In ...
Here, we describe a large-scale mass spectrometry-based proteomics approach to delineate phosphoproteome responses to the MEK inhibitor selumetinib in the context of KRAS-mutant lung cancer. Previous studies showed global phosphoproteome responses to MEK and RAF inhibition in the context of BRAF-mutant melanoma (48, 49); to our knowledge, this study is the first global phosphoproteomics approach that addresses how KRAS-mutant lung cancer cells respond to pharmacologic MEK inhibition. Importantly, we demonstrate widespread increases in protein phosphorylation following treatment with a MEK inhibitor, which at first glance seems counterintuitive. However, this result is consistent with other observations that kinase inhibitors can lead to increased phosphorylation of some substrate proteins. Previously, we revealed TBK1 knockdown leads to increased phosphorylation of EGFR, MET, and their downstream ERK→Jun, Myc in KRAS-mutant lung cancer cells (23). The tyrosine kinase inhibitor dasatinib ...

This study shows for the first time that the novel thiazole antibiotic thiostrepton selectively induces cell death in breast cancer cells through the down-regulation of FOXM1 expression. Furthermore, thiostrepton treatment, accompanied by a loss of FOXM1 expression, results in a reduction in the proliferation, invasiveness, and transformation ability of breast cells. Critically, thiostrepton has no affect on the proliferation of nontransformed breast epithelial cells.. Thiostrepton has been identified previously as an anticancer agent in a study of thiazole antibiotics and derivatives (16). We sought to identify the mechanism by which thiostrepton may induce cell death in breast cancer cells and determined the expression level and activity of a series of cell fate regulators in response to thiostrepton treatment. No change was observed in the phosphorylation status of the prosurvival factors Akt and ERK, whereas phosphorylation of FOXO3a, which we have reported previously as a critical mediator ...

0003]One component of the driving force of this market trend is and was certainly the assumption that, owing to their proportion of plastic, WPC are resistant to attack by fungi. However, only shortly after the market launch of WPC for the outdoor sector, reports of fungal growth of naturally weathered WPC appeared (P. I. Morris and P. Cooper, Forest Products Journal, 1998, 48(1), 86-88) and subsequent investigations in the laboratory clearly showed the susceptibility of WPC to fungal growth (e.g. P. E. Laks, Wood Design Focus, 2000, 11(4), 7.14; M. Mankowski and J. J. Morrell, Wood and Fiber Science, 2000, 32(3), 340-345; N. M. Stark et al., Journal of Applied Polymer Science, 2003, 90(10), 2609-2617). In particular, wood-discolouring fungi and fungi causing soft rot, such as, for example, Ascomycetes and Deuteromycetes, play an important role here. In addition to said fungi, wood-destroying fungi, such as, for example, Basidiomycetes, can also attack and destroy WPC. Further studies on ...

Thiopeptides, or thiazolyl peptides, are a relatively new family of antibiotics that already counts with more than one hundred different entities. Although they are mainly isolated from soil bacteria, during the last decade, new members have been isolated from marine samples. Far from being limited to their innate antibacterial activity, thiopeptides have been found to possess a wide range of biological properties, including anticancer, antiplasmodial, immunosuppressive, etc. In spite of their ribosomal origin, these highly posttranslationally processed peptides have posed a fascinating synthetic challenge, prompting the development of various methodologies and strategies. Regardless of their limited solubility, intensive investigations are bringing thiopeptide derivatives closer to the clinic, where they are likely to show their veritable therapeutic potential.

KIT inhibition with dasatinib represents a promising approach to targeted therapy in t(8;21) acute myeloid leukemia (AML) and clinical trials are currently evaluating its clinical relevance. However, data on continuous long-term dasatinib exposure of AML cells are limited and the potential effects on KIT inhibition and dasatinib sensitivity are unexplored. Treatment-related resistance ultimately limits clinical efficacy of tyrosine kinase inhibitors (TKI), which could similarly apply to dasatinib in t(8;21) AML. In this study, we used the dasatinib-sensitive KITmut t(8;21) AML cell line Kasumi-1 to model, in a confined and control- lable way, molecular effects upon continuous dasatinib treatment. Long-term dasatinib exposure at clinically relevant levels resulted in markedly decreased drug-sensitivity of KITmut t(8;21) AML cells. Notably, all dasatinib-resistant clones lacked secondary KIT-mutations. Instead, persistent growth correlated with alterations in KIT expression levelsdthat is, either KIT
