Small molecule fluorescent ligands as central nervous system imaging probes
The design, development and use of small molecule fluorescent ligands to directly or indirectly study receptors, enzymes and other targets in the central nervous system (CNS) have in the recent years become an intense area of investigation, especially for use in quantitative, sensitive and direct binding assays to study target proteins, both intra- and extra-cellularly and as prodromal diagnostic tools. The rapid development of ultra sensitive fluorescent spectroscopic approaches, such as fluorescence correlation spectroscopy, flow cytometry, confocal laser scanning microscopy, fluorescence polarization and multi-photon fluorescence microscopy, is opening new scenarios for the use of small molecule fluorescent ligands in the study of CNS pharmacology. In combination with effective and efficient labeling protocols, these techniques offer enormous possibilities at both micro- and nanometer level to develop parallel multifaceted tools in pharmacological and related sciences. This review covers small molecule fluorescent ligands that have been applied to study proteins and other targets in the CNS through visualization by means of fluorescent imaging technologies
Fluorescent polycyclic ligands for nitric oxide synthase (NOS) inhibition
In recent years polycyclic compounds have been shown to exhibit pharmacological profiles of importance in the symptomatic and proposed curative treatment of neurodegenerative diseases (e.g., Parkinson’s and Alzheimer’s disease). These structures also show modification and improvement of the pharmacokinetic and pharmacodynamic properties of drugs in current use. Nitric oxide (NO) is a molecular messenger involved in a number of physiological processes in mammals. It is synthesised by nitric oxide synthase (NOS) from l-arginine and its overproduction could lead to a number of neurological disorders. The aim of this study was to synthesise a series of novel indazole, indole and other fluorescent derivatives conjugated to polycyclic structures for evaluation in NOS assays. NOS is a target system where fluorescent techniques and fluorescently labelled NOS inhibitors can be used for detecting the biophysical properties of enzyme–ligand interactions and thus facilitate development of novel inhibitors of neurodegeneration. This could lead to a greater insight into the neuroprotective mechanism and a possible cure/treatment for neurodegenerative diseases. A series of compounds incorporating polycyclic structures such as 3-hydroxy-4-aza-8-oxoheptacyclo[9.4.1.0.2,100.3,140.4,90.9,13012,15]tetradecane and amantadine as well as suitable fluorescent moieties were selected for synthesis. In the biological evaluation the oxyhaemoglobin (oxyHb) assay was employed to determine the activity of the novel compounds at an enzymatic level of NOS. IC50 values of the novel fluorescent compounds were compared to that of aminoguanidine (AG) and 7-nitroindazole (7-NI), two known NOS inhibitors, and showed moderate to high affinity (IC50 values ranging from 7.73 μM to 0.291 μM) for the NOS enzym
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
