Both the antioxidant and D3 agonist actions of pramipexole mediate its neuroprotective actions in mesencephalic cultures. (1/804)

Pramipexole (PPX) is a full intrinsic activity, direct-acting dopamine (DA) agonist possessing 7-fold higher affinity for D3 than for D2 receptors. It also is a potent antioxidant. PPX was previously shown to be neuroprotective because it dose dependently attenuated the DA neuron loss produced by levodopa in mesencephalic cultures. Several different drugs with properties similar to PPX were studied here to better understand the mechanism or mechanisms responsible for this neuroprotective effect. The D3-preferring agonist 7-hydroxy-diphenylaminotetralin (7-OH-DPAT) and the D3 antagonist U99194, respectively, increased and decreased the neuroprotective effects of PPX in a dose-dependent fashion. Addition of the selective D2 agonist U95666 or the D2/D3 antagonists domperidone or raclopride did not affect PPX's neuroprotective effect. Interestingly, 7-OH-DPAT by itself did not attenuate the DA neuron loss produced by levodopa. However, when 7-OH-DPAT was combined with a low dose of the antioxidants U101033E or alpha-tocopherol, the toxic effects of levodopa were attenuated. Similar results were observed when the D3-preferring agonist PD128, 907 was studied. In addition, media conditioned by exposure of mesencephalic cultures incubated with all D3-preferring agonists studied was shown to enhance the growth of DA neurons in freshly harvested recipient cultures implicating a D3-mediated trophic activity in the neuroprotective effect. These data suggest that PPX's neuroprotective actions in the levodopa toxicity model are a consequence of its combined actions as a D3 receptor agonist and an antioxidant.  (+info)

Aldose reductase functions as a detoxification system for lipid peroxidation products in vasculitis. (2/804)

Giant cell arteritis (GCA) is a systemic vasculitis preferentially affecting large and medium-sized arteries. Inflammatory infiltrates in the arterial wall induce luminal occlusion with subsequent ischemia and degradation of the elastic membranes, allowing aneurysm formation. To identify pathways relevant to the disease process, differential display-PCR was used. The enzyme aldose reductase (AR), which is implicated in the regulation of tissue osmolarity, was found to be upregulated in the arteritic lesions. Upregulated AR expression was limited to areas of tissue destruction in inflamed arteries, where it was detected in T cells, macrophages, and smooth muscle cells. The production of AR was highly correlated with the presence of 4-hydroxynonenal (HNE), a toxic aldehyde and downstream product of lipid peroxidation. In vitro exposure of mononuclear cells to HNE was sufficient to induce AR production. The in vivo relationship of AR and HNE was explored by treating human GCA temporal artery-severe combined immunodeficiency (SCID) mouse chimeras with the AR inhibitors Sorbinil and Zopolrestat. Inhibition of AR increased HNE adducts twofold and the number of apoptotic cells in the arterial wall threefold. These data demonstrate that AR has a tissue-protective function by preventing damage from lipid peroxidation. We propose that AR is an oxidative defense mechanism able to neutralize the toxic effects of lipid peroxidation and has a role in limiting the arterial wall injury mediated by reactive oxygen species.  (+info)

Efficacy, safety, and tolerance of the non-ergoline dopamine agonist pramipexole in the treatment of advanced Parkinson's disease: a double blind, placebo controlled, randomised, multicentre study. (3/804)

OBJECTIVES: Pramipexole, a non-ergot dopamine D2/D3 receptor agonist, was investigated as an add on drug in advanced parkinsonian patients with motor fluctuations to assess efficacy, safety, and tolerance. METHODS: Seventy eight patients of either sex with advanced Parkinson's disease and treatment complications such as motor fluctuations were enrolled into a double blind, placebo controlled, randomised, multicentre study (phase II) and assigned to add on treatment with pramipexole (n=34) versus placebo (n=44) to a previously stabilised antiparkinsonian medication (7 week dose titration interval, 4 week maintenance period). The primary end point of efficacy was the change from baseline in the total score of the unified Parkinson's disease rating scale (UPDRS) in the on "period" (2 hours after intake of study medication). Safety and tolerability were assessed on the basis of adverse events, vital signs, laboratory measurements, and ECG recordings. RESULTS: There was a significant improvement of the pramipexole group in UPDRS total scores, subscores part II, III (activities of daily living and motor examination), and IV (complications of therapy). Mean UPDRS total score decreased by 37.3% under pramipexole compared with 12.2% under placebo (p<0.001). Patients under pramipexole reported an overall reduction in "off" periods of 12%--resulting in 1.7 more hours "on" time a day--compared with an increase in "off" periods of 2% under placebo. There were no unexpected safety results. The adverse event profile disclosed a high tolerability. The most important adverse events under pramipexole were fatigue, dyskinesia, and vivid dreams. CONCLUSION: Pramipexole administration is an efficacious and well tolerated add on therapy in patients with advanced Parkinson's disease with an improvement in activities of daily living, motor function, and treatment associated complications.  (+info)

Primary active transport of organic anions on bile canalicular membrane in humans. (4/804)

Biliary excretion of several anionic compounds was examined by assessing their ATP-dependent uptake in bile canalicular membrane vesicles (CMV) prepared from six human liver samples. 2, 4-Dinitrophenyl-S-glutathione (DNP-SG), leukotriene C4 (LTC4), sulfobromophthalein glutathione (BSP-SG), E3040 glucuronide (E-glu), beta-estradiol 17-(beta-D-glucuronide) (E2-17G), grepafloxacin glucuronide (GPFXG), pravastatin, BQ-123, and methotrexate, which are known to be substrates for the rat canalicular multispecific organic anion transporter, and taurocholic acid (TCA), a substrate for the bile acid transporter, were used as substrates. ATP-dependent and saturable uptake of TCA, DNP-SG, LTC4, E-glu, E2-17G, and GPFXG was observed in all human CMV preparations examined, suggesting that these compounds are excreted in the bile via a primary active transport system in humans. Primary active transport of the other substrates was also seen in some of CMV preparations but was negligible in the others. The ATP-dependent uptake of all the compounds exhibited a large inter-CMV variation, and there was a significant correlation between the uptake of glutathione conjugates (DNP-SG, LTC4, and BSP-SG) and glucuronides (E-glu, E2-17G, and GPFXG). However, there was no significant correlation between TCA and the other organic anions, implying that the transporters for TCA and for organic anions are different also in humans. When the average value for the ATP-dependent uptake by each preparation of human CMVs was compared with that of rat CMVs, the uptake of glutathione conjugates and nonconjugated anions (pravastatin, BQ-123, and methotrexate) in humans was approximately 3- to 76-fold lower than that in rats, whereas the uptake of glucuronides was similar in the two species. Thus there is a species difference in the primary active transport of organic anions across the bile canalicular membrane that is less marked for glucuronides.  (+info)

Kinetic control of multiple forms of Ca(2+) spikes by inositol trisphosphate in pancreatic acinar cells. (5/804)

The mechanisms of agonist-induced Ca(2+) spikes have been investigated using a caged inositol 1,4,5-trisphosphate (IP(3)) and a low-affinity Ca(2+) indicator, BTC, in pancreatic acinar cells. Rapid photolysis of caged IP(3) was able to reproduce acetylcholine (ACh)-induced three forms of Ca(2+) spikes: local Ca(2+) spikes and submicromolar (<1 microM) and micromolar (1-15 microM) global Ca(2+) spikes (Ca(2+) waves). These observations indicate that subcellular gradients of IP(3) sensitivity underlie all forms of ACh-induced Ca(2+) spikes, and that the amplitude and extent of Ca(2+) spikes are determined by the concentration of IP(3). IP(3)-induced local Ca(2+) spikes exhibited similar time courses to those generated by ACh, supporting a role for Ca(2+)-induced Ca(2+) release in local Ca(2+) spikes. In contrast, IP(3)- induced global Ca(2+) spikes were consistently faster than those evoked with ACh at all concentrations of IP(3) and ACh, suggesting that production of IP(3) via phospholipase C was slow and limited the spread of the Ca(2+) spikes. Indeed, gradual photolysis of caged IP(3) reproduced ACh-induced slow Ca(2+) spikes. Thus, local and global Ca(2+) spikes involve distinct mechanisms, and the kinetics of global Ca(2+) spikes depends on that of IP(3) production particularly in those cells such as acinar cells where heterogeneity in IP(3) sensitivity plays critical role.  (+info)

Attenuation of ischemia induced increases in sodium and calcium by the aldose reductase inhibitor zopolrestat. (6/804)

OBJECTIVE: We have previously demonstrated that zopolrestat, an inhibitor of the enzyme aldose reductase, reduces ischemic injury in hearts from diabetic and non-diabetic rats. To further explore potential cardioprotective mechanisms of zopolrestat, we measured changes in intracellular sodium, calcium, and Na+,K(+)-ATPase activity in zopolrestat treated hearts during ischemia and reperfusion. METHODS: Hearts from acute diabetic (Type I) and age-matched control rats were isolated and retrogradely perfused. Hearts had either control perfusion or exposure to 1 microM zopolrestat for 10 min, followed by 20 min of global ischemia and 60 min of reperfusion. Changes in intracellular sodium and calcium were measured using 23Na and 19F magnetic resonance spectroscopy, respectively, while the activity of Na+,K(+)-ATPase was measured using biochemical assays. RESULTS: Zopolrestat blunted the rise in [Na]i during ischemia in both diabetic hearts and non-diabetic hearts. The end-ischemic [Na]i was 21.3 +/- 2.6 mM in the zopolrestat treated diabetics and 25.9 +/- 2.3 in zopolrestat treated non-diabetics, versus 31.6 +/- 2.6 mM and 32.9 +/- 2.8 mM in the untreated diabetics and untreated non-diabetics, respectively, (P = 0.002). Similarly, the rise in [Ca]i at the end of ischemia was significantly reduced in zopolrestat treated diabetic and non-diabetic hearts (P = 0.005). Zopolrestat increased the activity of Na-,K(+)-ATPase in diabetic hearts under baseline conditions (11.70 +/- 0.95 versus 7.28 +/- 0.98 mumol/h/mg protein, P = 0.005) as well as during ischemia and reperfusion. Similar changes in Na+,K(+)-ATPase activity were also observed in non-diabetic hearts. CONCLUSIONS: The data provide additional support to the protective effects of zopolrestat and suggest that a possible mechanism of action may be associated with the attenuation of the rise in [Na]i and [Ca]i during ischemia and reperfusion.  (+info)

Antioxidant activity: what do we measure? (7/804)

Inhibition of oxidation of 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) by free radicals generated by decomposition of 2,2'-azobis(2-amidopropane) (ABAP) by antioxidants and biological material was studied. A correlation was found between the ability of various substances to delay the onset of ABTS oxidation and their rapid reduction of the ABTS+* cation radical, and between the ability to reduce the maximal rate of ABTS oxidation and slow reduction of ABTS+*. The length of the lag period of ABTS oxidation was found to be independent of ABTS concentration. Similar decrease of peroxynitrite-induced ABTS+* formation by antioxidants was observed when the antioxidants were added before and after peroxynitrite. All these findings indicate that the main effect of antioxidants in this system is reduction of ABTS+* and not prevention of its formation. Reduction of oxidation products rather than inhibition of their formation may be the predominant mode of action of antioxidants in various assays of antioxidant activity.  (+info)

Malaria vectors in a traditional dry zone village in Sri Lanka. (8/804)

Malaria transmission by anopheline mosquitoes was studied in a traditional tank-irrigation-based rice-producing village in the malaria-endemic low country dry zone of northcentral Sri Lanka during the period August 1994-February 1997. Adult mosquitoes were collected from human and bovid bait catches, bovid-baited trap huts, indoor catches, and pit traps. Mosquito head-thoraces were tested for the presence of Plasmodium falciparum and P. vivax, and blood-engorged abdomens for the presence of human blood by ELISAs. House surveys were done at two-day intervals to record cases of blood film-confirmed malaria among the villagers. A total of 7,823 female anophelines representing 14 species were collected. Trends in anopheline abundance were significantly correlated with rainfall of the preceding month in An. annularis, An. barbirostris, An. subpictus, An. vagus, and An. varuna, but were not significant in An. culicifacies and An. peditaeniatus. Malaria parasite infections were seen in seven mosquito species, with 75% of the positive mosquitoes containing P. falciparum and 25% P. vivax. Polymorph PV247 was recorded from a vector (i.e., An. varuna) for the first time in Sri Lanka. Computations of mean number of infective vector (MIV) rates using abundance, circumsporozoite (CS) protein rate, and human blood index (HBI) showed the highest rate in An. culicifacies. A malaria outbreak occurred from October 1994 to January 1995 in which 45.5% of village residents experienced at least a single disease episode. Thereafter, malaria incidence remained low. Anopheles culicifacies abundance lagged by one month correlated positively with monthly malaria incidence during the outbreak period, and although this species ranked fifth in terms of abundance, infection was associated with a high MIV rate due to a high CS protein rate and HBI. Abundance trends in other species did not correlate significantly with malaria. It was concluded that An. culicifacies was epidemiologically the most important vector in the study area.  (+info)

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 ...

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 ...

Preliminary irritation study: The necrosis seen at intradermal injection of the lowest concentration (2%) was considered to be caused mainly by polyethylene glycol rather than the test substance. Based on the results, the test substance concentrations selected for the main study were a 2% concentration for the intradermal induction and a 50% concentration for the epidermal induction exposure. No signs of irritation were observed to the highest test substance concentration epidermally tested. Therefore, the test site of all animals was treated with 10% SDS approximately 24 hours before the epidermal induction in the main study, to provoke a mild inflammatory reaction. A 50% test substance concentration was selected for the challenge phase. Main study results: -Induction phase: The signs of necrosis seen in the control animals after the intradermal injection with vehicle only were in consistency with the results in the preliminary irritation study after injection of polyethylene glycol.

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 main types of rubber components where residues of MBT and BT may be found include natural rubber or nitrile rubber seals and gaskets used in food processing equipment. MBT is formed ...

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 ...
