Patients with Parkinson disease are prescribed dopamine agonists such as pramipexole to improve motor symptoms. Several studies have found that patients taking dopaminergic medication develop impulse control disorders. In contrast, other studies suggest that some behaviors become less impulsive with pramipexole. We evaluated the performance of 20 young, healthy participants who received pramipexole (0.5 mg) and 20 participants who received placebo, on the Go/No-Go, the Stop Signal Task, and the Balloon Analogue Risk Task. We found that the pramipexole group had more timed out Go trials on the Go/No-Go task than the placebo group, suggesting reduced motor impulsivity. There were no differences between the two groups performance on the other impulsivity tasks. This pattern of results is in line with the theory that impulsivity consists of a motor and a cognitive aspect, and that pramipexole might decrease motor, but not cognitive impulsivity.

A series of new benzothiazole derivatives containing dimethylpyrazole were synthesized and evaluated for their anticonvulsant activity, neurotoxicity and cytotoxicity by using the maximal electroshock (MES), rotarod neurotoxicity (TOX) and MTT colorimetric assay. Among the compounds studied, four compounds (6a, 6b, 6g and 6m) showed better anticonvulsant than the others at 300 mg/kg and they also showed anticonvulsant activity at the dose of 100 mg/kg. All the synthetic compounds showed lower neurotoxicity and little cytotoxicity, so that the compounds, which with better activities, also had higher protective index. In particular, the compound 6g, 2-(3,5-dimethyl-1H-pyrazol-1-yl)-6-((2-fluorobenzyl)oxy)benzo[d]thiazole showed better activity with an ED50 value of 160.4 mg/kg and higher protective index (PI) values of 2.74 in the MES test than the standard drugs sodium valproate, which used as positive controls in this study. After that the compound 6g demonstrated antagonistic activity against seizures

This pathway was started by Janice Frias, University of Minnesota, BioC/MicE 5309, and completed by Carla Essenberg and Jiun-guo Yu, University of Minnesota. 2-Mercaptobenzothiazole (MBT) is used primarily as a vulcanization accelerator in the production of rubber, although it is also used to inhibit the corrosion of copper in water and as an ingredient in cutting oils and petroleum products (Whittaker et al., 2004, De Wever et al., 1998). The manufacture of MBT produces wastewaters with high levels of MBT and its derivatives, and these compounds can also be released into water by factories using MBT and by leaching from MBT-containing products, particularly rubber (De Wever et al., 1998). Many other industries also use benzothiazoles, which in some cases degrade to MBT. For example, MBT is a degradation product of a fungicide widely used in the leather and lumber industries, 2-(thiocyanomethylthio)benzothiazole (Reemtsma, Fiehn, Kalnowski, and Jekel (1995) Environ Sci Technol 29:478-485).

NVP-231: A Competitive CerK Inhibitor. We developed a homogeneous CerK assay for high-throughput screening based on a luminescent reaction measuring ATP consumption (Koresawa and Okabe, 2004; Klumpp et al., 2006). After miniaturization of this assay to a 1536-well plate format, we screened over a million compounds for inhibition of CerK. Primary hits active in the micromolar range were confirmed or invalidated by dose-response experiments, which also provided a preliminary ranking. The overlap to hit lists from other kinase inhibitor screens using the same assay principle was very limited, indicating specificity of the hit compounds for CerK. Although the screened libraries contained many typical protein kinase inhibitors, only a few of them inhibited CerK. Further hit validation was conducted using a direct enzymatic assay measuring the incorporation of radioactive phosphate into C1P.. One of the compounds identified as the benzothiazole derivative 1 (or NVP-231) showed an IC50 value of 12 ± 2 ...

Background: The cerebrospinal fluid (CSF) amyloid-β (Aβ)1-42, total-tau (T-tau), and phosphorylated-tau (P-tau181P) profile has been established as a valuable biomarker for Alzheimers disease (AD). Objective: The current study aimed to determine CSF biomarker cut-points using positron emission tomography (PET) Aβ imaging screened subjects from the Australian Imaging, Biomarkers and Lifestyle (AIBL) study of aging, as well as correlate CSF analyte cut-points across a range of PET Aβ amyloid ligands. Methods: Aβ pathology was determined by PET imaging, utilizing 11C-Pittsburgh Compound B, 18F-flutemetamol, or 18F-florbetapir, in 157 AIBL participants who also underwent CSF collection. Using an INNOTEST assay, cut-points were established (Aβ1-42 ,544 ng/L, T-tau ,407 ng/L, and P-tau181P ,78 ng/L) employing a rank based method to define a positive CSF in the sub-cohort of amyloid-PET negative healthy participants (n = 97), and compared with the presence of PET demonstrated AD pathology. ...

Abstract: The experimental infrared (IR), nuclear magnetic resonance (NMR), and ultraviolet (UV) spectra, and density functional theory (DFT) calculations of the novel compound N, N-di[3-hydroxy-4-(2-benzothiazole) phenyl]urea (4-DHBTU) are presented. Compared with the UV spectra of the 2-(4-amino-2-hydroxyphenyl) benzothiazole (4-AHBT) monomer, the experimental spectra of 4-DHBTU, a dimer of 4-AHBT, show dualwavelength absorption with significantly enhanced absorption intensity and an obvious red shift of the maximum absorption peak. Analysis of the experimental spectra and the DFT calculations shows that the structures of cis-C11 and trans-C11 are the two most stable conformers, and that the main reason for the different UV spectral properties of the dimer and monomer is the coexistence of cis-C11, trans-C11, cis-C22, and trans-C22 in the 4-DHBTU sample. In addition, the DFT calculations indicate that a hydrogen-bonding interaction between 4-DHBTU and the dimethyl sulfoxide (DMSO) solvent ...

Small-conductance (KCa2) and intermediate-conductance (KCa3.1) calcium-activated K+ channels are voltage-independent and share a common calcium/calmodulin-mediated gating mechanism. Existing positive gating modulators like EBIO, NS309, or SKA-31 activate both KCa2 and KCa3.1 channels with similar potency or, as in the case of CyPPA and NS13001, selectively activate KCa2.2 and KCa2.3 channels. We performed a structure-activity relationship (SAR) study with the aim of optimizing the benzothiazole pharmacophore of SKA-31 toward KCa3.1 selectivity. We identified SKA-111 (5-methylnaphtho[1,2-d]thiazol-2-amine), which displays 123-fold selectivity for KCa3.1 (EC50 111 ± 27 nM) over KCa2.3 (EC50 13.7 ± 6.9 μM), and SKA-121 (5-methylnaphtho[2,1-d]oxazol-2-amine), which displays 41-fold selectivity for KCa3.1 (EC50 109 nM ± 14 nM) over KCa2.3 (EC50 4.4 ± 1.6 μM). Both compounds are 200- to 400-fold selective over representative KV (KV1.3, KV2.1, KV3.1, and KV11.1), NaV (NaV1.2, NaV1.4, NaV1.5, and ...

The criteria for diagnosing Alzheimers disease (AD) have recently been revised to include the use of biomarkers for the in vivo presence of β-amyloid, one of the neuropathological hallmarks of AD. Examples of such biomarkers are positron emission tomography (PET) β-amyloid specific ligands, including [18F]flutemetamol. The aim of this thesis was to characterize the binding properties of [18F]flutemetamol from a tracer kinetic perspective as well as by validating binding measures through comparison with tissue pathology assessments. The applicability of previously developed kinetic models of tracer binding for voxel-based analysis was examined and compared to arterial input compartment modelling, the gold standard for PET quantification. Several voxel-based methods were found to exhibit high correlations with compartment modelling, including the semi-quantitative standardized uptake value ratio (SUVR). The kinetic components of [18F]flutemetamol uptake were also investigated without model ...

Patients should be instructed to take pramipexole dihydrochloride tablets only as prescribed. Patients should be alerted to the potential sedating effects associated with pramipexole dihydrochloride tablets, including somnolence and the possibility of falling asleep while engaged in activities of daily living. Since somnolence is a frequent adverse event with potentially serious consequences, patients should neither drive a car nor engage in other potentially dangerous activities until they have gained sufficient experience with pramipexole dihydrochloride tablets to gauge whether or not it affects their mental and/or motor performance adversely. Patients should be advised that if increased somnolence or new episodes of falling asleep during activities of daily living (e.g., watching television, passenger in a car, etc.) are experienced at any time during treatment, they should not drive or participate in potentially dangerous activities until they have contacted their physician. Because of ...

This study was designed to investigate the activity of CGP 20376, a benzothiazole derivative, against Brugia malayi in jirds and to illustrate the utility of parasite antigen detection as a means of monitoring drug efficacy in filariasis. Drug treatment was 100% effective in jirds treated 3 or 24 days after infection. Microfilaria and adult worm counts were reduced (relative to counts in sham-treated control animals) by 96% and 95%, respectively, in animals treated 153 days after infection. Four of 6 animals in this treatment group cleared their microfilaremias and were free of adult worms 5 mo after treatment. Thus, CGP 20376 was effective against all life cycle stages of B. malayi in jirds. Parasite antigen levels in jird sera were consistent with parasitological results in all treatment groups, but antigen clearance was incomplete in some cases after apparently successful treatment of mature and immature infections.

Although the gold standard diagnostic tool for cardiac amyloidosis is endomyocardial biopsy (5), investigators have tried to assess this disease noninvasively with various imaging techniques. Although some molecular imaging-based methods have been successful (8,12), most of them have been unsuccessful for demonstrating amyloid deposits in the myocardium (13). The CMR has also been successful in the diagnosis of cardiac amyloidosis (14), but it may not be specific for amyloid deposits (15). Therefore, there is a clinical need to foster imaging-based diagnosis into clinical utility.. 11C-PiB has been used recently for early detection and for follow-up of Alzheimers dementia (16), a disease characterized by accumulation of β-amyloid plaque in the brain parenchyme. It is a radioactive derivative of benzothiazole that binds with conformational dependence to any type of β-amyloid sheet structure (7). Indeed, this has been demonstrated in various mouse models (17) and in human autopsy studies of the ...

CALM-PD study found that Pramipexole can reduce the occurrence of motor complication compared with Levodopa used as initiative treatment, but it still remains debatable that initiation of which medication will be better for those patients with De Novo PD.. PDRP (Parkinsons disease-related spatial covariance pattern) is a biomarker which can represent the network activity of cortico-striato-pallido-thalamocortical pathways and highly reproducible with stable network activity in individual subjects. The study published in J Neuroscience in 2010 showed that the abnormal PDRP antecede the appearance of motor signs by about 2 years, indicating PDRP might be a very promising biomarker for identifying PD at its early stage. Moreover, PDRP is able to represent the progression and severity of PD as well. It was reported that Levodopa can reduce the PD-related network activity, and the degree of network suppression correlates with the clinical improvement. However, there is no study currently showing ...

It is inherently undesirable for any chemical component of the rubber to migrate into a foodstuff during processing or storage. Rubber compounds are complex formulations that undergo chemical transformation during vulcanisation.. Rubber components that can potentially migrate include low molecular mass monomers, vulcanising agents, plasticisers, oils and waxes and their breakdown products. For example, polar plasticisers such as di-2-ethylhexyl phthalate are readily soluble in alcohol so plasticised rubbers should not be used in contact with alcoholic beverages.. The compounds 2-mercaptobenzothiazole (MBT) and benzothiazole (BT) may migrate from rubber during the manufacture and storage of food or drink. Research has shown that this might happen. Both MBT and BT migrated from rubber into laboratory solvents..

The three organometallic complexes [(Cis-Pt^II (DDH) (2,5- Dihidroxibenzensulfonic)^2, Rh^I (CO)2 Cl(2- Aminobenzothiazole) and Rh^I (CO)2 Cl(5-Cl-2- Methilbenzothiazole)] used in this study had been previously found to have a high in vitro activity against promastigote and amastigote like forms of Leishmania donovani. Here, the cytotoxic effect of these new organometallic complexes on the J-774 macrophages were studied. Only the Rh^I(CO)2 Cl (2-Aminobenzothiazole) complex induced substantial toxicity in the cells.. Also, we assayed the effect of this complex on the parasite s biosynthesis of macromolecules. The Rh^I(CO)2Cl (5-Cl-2- Methylbenzothiazole) complex inhibited DNA, RNA, and protein synthesis. On the other hand, the two other compounds tested did not inhibit the incorporation of radioactive precursors. Finally important ultrastructural alterations in the parasites treated with the two non-cytotoxic complexes were observed ...

A number of compounds of interest as possible purine or pyrimidine antagonists have been assayed for anti-leukemic action against transplanted lymphoid leukemia (Ak 4) in mice.. The pyrimidines studied were uniformly inactive.. Of the 2,6-diaminopurine derivatives assayed, only the parent compound definitely increased survival time. Introduction of a hydroxy, mercapto, or iodo group at the 8-position of 2,6-diaminopurine apparently inactivates this anti-leukemic molecule.. Benzimidazole, 2-chloromethylbenzimidazole, 5-nitrobenzotriazole, indole, benzoxazole, benzothiazole, 2-methyl-4-hydroxyquinazoline, and 2,3,5-triphenyltetrazolium chloride were screened but showed no anti-leukemic activity.. ...

Haploinsufficiency of Meis1 is a potential model system for simulating RLS in mice. Here, we show that this Meis1 deficit causes a sex- and context-dependent RLS-related phenotype at middle age, impaired sensorimotor gating ability that was refractory to the D2/3R agonist pramipexole as well as increased social memory. These behavioral abnormalities occurred without differences in thermal sensitivity, plasma iron concentrations or dopaminergic neuron number in the SNpc/VTA. Thus, although Meis1 haploinsufficiency causes the RLS-related phenotype of motor restlessness in mice, the detailed nature of these effects is complex. Furthermore, it is characteristically distinct from other genetic RLS models (e.g. Btbd9 knock-out), highlighting the heterogeneous nature of the effects of these different risk genotypes in this disease.. Motor restlessness in these Meis1-haploinsufficient mice was detected previously in young adult male and female mice (Spieler et al., 2014). RLS is, however, more prevalent ...
