Introduction: 5-Hydroxy-[beta-11C]-L-tryptophan ([11C]HTP) is an established positron emission tomography (PET) imaging agent for neuroendocrine tumors (NETs). It has also been used for other clinical research purposes in neurology and diabetes. However, its widespread use is limited by the short physical half-life of the radionuclide and a difficult radiosynthesis. Therefore, a Fluorine-18 labeled analogue, 5-[18F]Fluoro-L-tryptophan ([18F]FTRP), has been proposed as a functional analogue. There is no published method for the synthesis of L-[18F]FTRP. We have therefore developed a synthesis of 5-fluoro-[beta-11C]-L-tryptophan ([11C]FTRP), based on the existing chemo-enzymatic method for [11C]HTP and evaluated the potential usefulness of radiolabeled FTRP as a substitute for [11C]HTP. Methods: The in vitro and in vivo behavior of [11C]FTRP, including the dependence of key enzymes in the serotonergic metabolic pathway, was investigated in NET cell lines, NET xenograft carrying immunodeficient mice, normal rats and in non-human primate. [11C]HTP was used for direct comparison. Results: Uptake of [11C]FTRP in NET cell lines in vitro was mediated by enzymes involved in serotonin synthesis and metabolism, similar to [11C]HTP. In vivo biodistribution, either in rodent or non-human primate, was not affected by selectively inhibiting enzymatic steps in the serotonergic metabolic pathway. Conclusion: [11C]FTRP has in vitro biological function similar to that of [11C]HTP. However, this function is not retained in vivo as shown by biodistribution and PET/CT studies. Radiolabeled FTRP is thus not likely to provide an advantage over [11C]HTP in PET imaging in oncology, neurology or diabetes.

Mutations in leucine-rich repeat kinase-2 (LRRK2) are the most common genetic cause of Parkinson’s disease (PD). The most frequent kinase-enhancing mutation is the G2019S residing in the kinase activation domain. This opens up a promising therapeutic avenue for drug discovery targeting the kinase activity of LRRK2 in PD. Several LRRK2 inhibitors have been reported to date. Here, we report a selective, brain penetrant LRRK2 inhibitor and demonstrate by a competition pulldown assay in vivo target engagement in mice.

Biofilms are complex microbial architectures that attach to surfaces and encase microorganisms in a matrix composed of self-produced hydrated extracellular polymeric substances (EPSs). In biofilms, microorganisms become much more resistant to antimicrobial treatments, harsh environmental conditions, and host immunity. Biofilm formation by microbial pathogens greatly enhances survival in hosts and causes chronic infections that result in persistent inflammation and tissue damages. Currently, it is believed over 80% of chronic infectious diseases are mediated by biofilms, and it is known that conventional antibiotic medications are inadequate at eradicating these biofilm-mediated infections. This situation demands new strategies for biofilm-associated infections, and currently, researchers focus on the development of antibiofilm agents that are specific to biofilms, but are nontoxic, because it is believed that this prevents the development of drug resistance. Here, we review the most promising antibiofilm agents undergoing intensive research and development.

The progression of hyperuricemia disease is often accompanied by damage to renal function. However, there are few studies on hyperuricemia nephropathy, especially its association with intestinal flora. This study combines metabolomics and gut microbiota diversity analysis to explore metabolic changes using a rat model as well as the changes in intestinal flora composition. The results showed that amino acid metabolism was disturbed with serine, glutamate and glutamine being downregulated whilst glycine, hydroxyproline and alanine being upregulated. The combined glycine, serine and glutamate could predict hyperuricemia nephropathy with an area under the curve of 1.00. Imbalanced intestinal flora was also observed. Flavobacterium, Myroides, Corynebacterium, Alcaligenaceae, Oligella and other conditional pathogens increased significantly in the model group, while Blautia and Roseburia, the short-chain fatty acid producing bacteria, declined greatly. At phylum, family and genus levels, disordered nitrogen circulation in gut microbiota was detected. In the model group, the uric acid decomposition pathway was enhanced with reinforced urea liver-intestine circulation. The results implied that the intestinal flora play a vital role in the pathogenesis of hyperuricemia nephropathy. Hence, modulation of gut microbiota or targeting at metabolic enzymes, i.e., urease, could assist the treatment and prevention of this disease.

In vertebrates, numerous processes occur in a rhythmic manner. The hormonal signal reliably reflecting the environmental light conditions is melatonin. Nocturnal melatonin secretion patterns could be disturbed in pathophysiological states, including inflammation, Alzheimer’s disease, and depression. All of these states share common elements in their aetiology, including the overexpression of interleukin- (IL-) 1beta in the central nervous system. Therefore, the present study was designed to determine the effect of the central injection of exogenous IL-1beta on melatonin release and on the expression of the enzymes of the melatonin biosynthetic pathway in the pineal gland of ewe. It was found that intracerebroventricular injections of IL-1beta (50 mug/animal) suppressed (P < 0.05) nocturnal melatonin secretion in sheep regardless of the photoperiod. This may have resulted from decreased (P < 0.05) synthesis of the melatonin intermediate serotonin, which may have resulted, at least partially, from a reduced expression of tryptophan hydroxylase. IL-1beta also inhibited (P < 0.05) the expression of the melatonin rhythm enzyme arylalkylamine-N-acetyltransferase and hydroxyindole-O-methyltransferase. However, the ability of IL-1beta to affect the expression of these enzymes was dependent upon the photoperiod. Our study may shed new light on the role of central IL-1beta in the aetiology of disruptions in melatonin secretion.

In the present work, a commercially used azo dye Remazol navy blue was completely degraded into less toxic intermediates in an integrated microbial fuel cell-aerobic system. A novel defined bacterial consortium comprising of organisms isolated from dye contaminated wastewater has been used as inoculum for this study. As compared to the traditional static incubation method, a rapid decolorization of Remazol navy blue was noticed in the anodic chamber of microbial fuel cell. In low to moderate dye concentrations (25?100 mg/L), almost complete decolorization of Remazol navy blue was achieved within 12 h of microbial fuel cell operation. The first-order kinetic constant of Remazol navy blue decolorization (k) in microbial fuel cell was found to be considerably higher than that of static incubation condition (Kstatic (0.3041) < KMFC (0.5697)). Microbial fuel cells external resistance is found to be a key parameter affecting the reductive decolorization of Remazol navy blue dye with a resistance of 1000 ? as the optimum giving maximum efficiency. Dye degradation products from each stage of the integrated microbial fuel cell-aerobic system have been analyzed through different analytical techniques such as UV?Vis spectroscopy, Fourier transform infrared spectroscopy and gas chromatography?mass spectrometry analysis. These studies illustrate the reductive degradation of Remazol navy blue in microbial fuel cell treatment stage into different toxic intermediates which were further degraded into simpler compounds in the successive aerobic treatment stage. Phototoxicity study confirms the less toxic nature of the treated effluents as compared to the parent dye. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application of 1953-54-4, you can also check out more blogs about1953-54-4
