The recent outbreak of the Ebola virus in West Africa has highlighted the clear shortage of broad-spectrum antiviral drugs for emerging viruses. There are numerous FDA approved drugs and other small molecules described in the literature that could be further evaluated for their potential as antiviral compounds. These molecules are in addition to the few new antivirals that have been tested in Ebola patients but were not originally developed against the Ebola virus, and may play an important role as we await an effective vaccine. The balance between using FDA approved drugs versus novel antivirals with minimal safety and no efficacy data in humans should be considered. We have evaluated 55 molecules from the perspective of an experienced medicinal chemist as well as using simple molecular properties and have highlighted 16 compounds that have desirable qualities as well as those that may be less desirable. In addition we propose that a collaborative database for sharing such published and novel information on small molecules is needed for the research community studying the Ebola virus.

Monoamine oxidases are the crucial drug targets for the treatment of neurodegenerative disorders like depression, Parkinson’s disease, and Alzheimer’s disease. The enzymes catalyze the oxidative deamination of several monoamine containing neurotransmitters, i.e. serotonin (5-HT), melatonin, epinephrine, norepinephrine, phenylethylamine, benzylamine, dopamine, tyramine, etc. The oxidative reaction of monoamine oxidases results in the production of hydrogen peroxide that leads to the neurodegeneration process. Therefore, the inhibition of monoamine oxidases has shown a profound effect against neurodegenerative diseases. At present, the design and development of newer lead molecules for the inhibition of monoamine oxidases are under intensive research in the field of medicinal chemistry. Recently, the advancement in QSAR methodologies has shown considerable interest in the development of monoamine oxidase inhibitors. The present review describes the development of QSAR methodologies, and their role in the design of newer monoamine oxidase inhibitors. It will assist the medicinal chemist in the identification of selective and potent monoamine oxidase inhibitors from various chemical scaffolds.

Sixty years ago, the Australian chemist Francis P. Dwyer pioneered the use of ruthenium polypyridyl complexes as biologically active compounds. These chemically inert and configurationally stable complexes revealed an astonishing range of interesting biological activities, such as the inhibition of the enzyme acetylcholinesterase, anti-cancer activity in vivo, and bacteriostatic/bacteriocidal action. This review commemorates the sixtieth anniversary of Dwyer and co-workers’ landmark 1952 publication, summarises their broader achievements in biological inorganic chemistry, and discusses the contribution of this work to the development of modern biological and medicinal inorganic chemistry.

Following the publication of the history and development of QSAR, it became apparent that a number of matters had not been covered. This addendum is an attempt to rectify that. A very early approach (ca. 60 B.C.) by Lucretius shows that he understood how molecular size and complexity affect liquid viscosity. Comments by Kant (1724-1804) emphasized the necessity of mathematics in science. A claim that the work of von Bibra and Harless in 1847 pre-dated that of Overton and H.H. Meyer is shown not to be correct. K.H. Meyer and Gottlieb-Billroth published in 1920 what is probably the first QSAR equation. Brown, who with his co-author Fraser is credited with the first definitive recognition in 1868-9 that biological activity is a function of molecular structure, is often cited as Crum Brown; in fact, Crum was his second given name. The QSAR work of the Soviet chemist N.V. Lazarev in the 1940s was far ahead of his time, showing numerous correlations of biological activities and physicochemical properties with molecular descriptors. The subject of inverse QSAR is discussed.

AbstractAfter an esteemed academic career as a chemist, Michael Polanyi switched to the social sciences and made significant contributions to our understanding of the nature and role of knowledge in society. Polanyi's argument concerning knowledge led him to emphasise the vital importance of decentralised mechanisms of adjustment and coordination, including markets. His article ‘Collectivist Planning’ (1940) enters into debates about the possibility (or otherwise) of centrally planning scientific and economic activity. This early article also foreshadows post-war debates within the Mont Pèlerin Socierty (formed in 1947) concerning the economic role of the state and the future of liberalism.

Dihydropyrimidinones and thiones are a significant class of organic as well as heterocyclic compounds synthesized by cyclo condensation reaction, called Biginelli reaction that was reported for the first time by Italian chemist Pietro Biginelli in 1893. The synthesis of dihydropyrimidinones and thiones involve one pot multicomponent reaction (MCR) of various aldehydes, β- ketoester and urea or thiourea. Now, the dihydropyrimidinones and thiones have emerged as one of the most advantaged medicinal pharmacophores as they appear as an important structural part in many naturally occurring and synthetically prepared medicinal drugs. It possesses wide spectrum of biological activities like antitubercular, Anti-malarial, anticancer, anti-HIV activity, analgesic, antiepileptic, CNS activity, anti-inflammatory, calcium and potassium channel blocker [2], antihypertensive agents [3], α-la-antagonist [4], antioxidants [6] and neuropeptide Y (NPY) antagonists.[7]

Fournier, Etienne. "Intérêt de la prise en compte des variabilités de l’activité et de l’acceptabilité dans le cadre d’une conception centrée utilisateurs des situations de travail collaboratives Humain-Robot". Electronic Thesis or Diss., Université Grenoble Alpes, 2024. http://www.theses.fr/2024GRALH011.

La Commission Européenne encourage l’utilisation de robots collaboratifs (cobots) pour assister l’humain dans son travail. Cependant, les cobots semblent avoir des difficultés à transformer favorablement les situations de travail lorsqu’ils ne prennent pas en compte les variabilités des situations. Cette thèse s’est donc donnée comme objectifs de caractériser les variabilités dans le cadre d’une l’implémentation cobotique et de guider une démarche de conception centrée sur les futurs utilisateurs en mobilisant les approches d’acceptabilité, d’acceptation et d’expérience utilisateur. Une analyse de l’activité a été conduite dans un laboratoire de chimie dans le cadre d’une future implémentation cobotique. 11 opérateurs ont été observés durant leur activité et 34 ont participé à des entretiens semi-directifs. Les résultats ont permis d’identifier que l’activité en boîte à gants était le poste de travail qui bénéficierait le plus d’une collaboration cobotique. De même, ils ont montré une invisibilisation de certaines activités due à un écart entre le travail prescrit et l’activité d’où résultent des expositions aux risques régulières qui pourraient être évitées via une implémentation cobotique. Nous avons ainsi identifié plusieurs variabilités ayant des effets sur l’activité des opérateurs. Celles-ci ont servi à élaborer des paradigmes expérimentaux afin de tester l’effet d’une collaboration cobotique. Trois Tests Utilisateurs ont été réalisés avec au total 212 participants qui devaient réaliser des tâches d’assemblage de type industriel où une ou plusieurs variabilités étaient prises en charge dès la conception cobotique. La tâche était réalisée ou bien seul, ou bien en binôme avec un autre humain ou avec un cobot (YuMi d’ABB). Différents types de mesure ont été effectués : la charge de travail (évaluée via la NASA TLX, Hart, 2006 ; Hart & Staveland, 1988), le nombre d’erreurs, le nombre de gestes, le temps de réalisation, le degré d’acceptabilité de la collaboration cobotique (évalué via le TAM, Venkatesh et al., 2012) et l’exposition aux risques simulée. La collaboration cobotique a diminué les effets négatifs de plusieurs variabilités (e.g. variabilité du niveau de difficulté, variabilité de l’expertise de l’opérateur) sur la charge mentale de l’opérateur et sur le succès à la tâche. Les participants ont eu un meilleur taux de succès à la tâche lorsqu’ils collaboraient avec un cobot, même s’ils mettaient par ailleurs plus de temps à réaliser la tâche. De plus, les participants ont déclaré avoir plaisir à collaborer avec un cobot et avoir confiance en les informations qu’il fournissait (mesurés via une échelle d’items issus de l’étude de Martin, 2018). Enfin, quand le cobot s’adaptait aux contraintes de sécurité de l’humain, ce dernier s’exposait à moins de risques. D’un point de vue théorique, ces études empiriques ont permis de proposer un cadre intégrant les modèles de variabilités au travail et d’apporter des précisions sur les effets de la collaboration cobotique sur l’humain et sa tâche. D’un point de vue pratique, ces différentes études nous ont permis de proposer une grille de repérage des variabilités et de formuler des recommandations visant à accompagner l’implémentation d’une collaboration cobotique
The European Commission is encouraging the use of collaborative robots (cobots) to assist humans in their work. However, cobots seem to have difficulty in favorably transforming work situations when they do not consider the variabilities of the situations. The aim of this thesis was therefore to characterize variability in the context of a cobotic implementation, and to guide a design approach focused on future users, using acceptability, acceptance and user experience approaches. An activity analysis was carried out in a chemical laboratory as part of a future cobotic implementation. 11 operators were observed during their activity and 34 took part in semi-directive interviews. The results identified glovebox activity as the workstation that would benefit most from cobotic collaboration. They also showed that certain activities were rendered invisible due to a discrepancy between prescribed work and actual activity, resulting in regular exposure to risks that could be avoided through cobotic implementation. We have thus identified several variabilities with effects on operator activity. These were used to design experimental paradigms to test the effect of cobotic collaboration. Three User Tests were carried out with a total of 212 participants, who were asked to perform industrial assembly tasks where one or more variabilities were considered in the cobotic design. The task was performed either alone, or in pairs with another human or with a cobot (ABB's YuMi). Different types of measurement were carried out: workload (assessed via NASA TLX, Hart, 2006; Hart & Staveland, 1988), number of errors, number of gestures, completion time, degree of acceptability of cobotic collaboration (assessed via TAM, Venkatesh et al., 2012) and simulated risk exposure. Cobotic collaboration reduced the negative effects of several variabilities (e.g. variability in difficulty level, variability in operator expertise) on operator mental load and task success. Participants had a higher task success rate when collaborating with a cobot, even though they otherwise took longer to complete the task. In addition, participants reported enjoying collaborating with a cobot and having confidence in the information it provided (measured via a scale of items from Martin, 2018). Finally, when the cobot adapted to the human's safety constraints, the latter exposed himself to fewer risks. From a theoretical point of view, these empirical studies made it possible to propose a framework integrating models of variability at work, and to shed light on the effects of cobotic collaboration on the human and his task. From a practical point of view, these different studies have enabled us to propose a grid for identifying variabilities and to formulate recommendations designed to support the implementation of cobotic collaboration

Resumo:
The ability of glucosinolates to act as host recognition cues and oviposition stimulants for root flies has been previously established. To further investigate the interactions between pest and glucosinolate a number of simple and complex glucosinolates were synthesised and tested by contact chemoreception. A crude structure-activity relationship was identified whereby the stimulatory activity of the glucosinolate increased as the alkyl side chain was increased from propyl to pentyl, heptyl and nonyl. Comparison of the novel synthetic glucosinolate, naphthylmethyl glucosinolate, with glucobrassicin, a naturally occurring indole derivative, showed the former to have little or no activity whereas the latter is the most active natural stimulant. The synthetic glucosinolates were also demonstrated to act as substrates for the enzyme myrosinase, being hydrolysed to ?-D-glucose and the corresponding isothiocyanate. In addition, (7-methoxycarbonylheptyl) glucosinolate, prepared as a precursor to (7-carboxyheptyl) glucosinolate, was found to be a substrate. High resolution NMR studies of the latter compound showed this acidic glucosinolate and indeed alkyl glucosinolates to adopt an unexpected conformation in aqueous solution. Furthermore, a number of alkyl thiohydroximates were synthesised and used as HPLC and LC-MS standards to aid glucosinolate identification. Isothiocyanates have been identified as chemopreventative agents which inhibit carcinogen activation mediated by cytochrome P450 enzymes. The postulated oxidation of isothiocyanates to isocyanates by these enzymes, was studied using a number of chemical model systems. Oxidation of isothiocyanates was efficiently achieved using dimethyl dioxirane (DMD). Although, the resulting isocyanates could not be isolated, their production was confirmed by GC/MS and FT-IR analysis of reaction solutions. A number of ureas were also prepared by trapping the isocyanates in situ. These compounds were demonstrated to arise from the isocyanate and not oxidation of the corresponding thiourea. In addition, peracids were found to produce isocyanates, although less efficiently.

The synthesis and structure of 1,2-quinone mono-oximes have been reviewed. The reaction of 3-hydroxyphenol, 3-hydroxy-2-aethylphenol, 3-hydroxy-5-methylphenol and N-acetyl-3-aminophenol with amyl nitrite/M(OEt) (M - Na or K) has been systematically examined. It has been found that the complex formed depends on the reaction temperature and phenol/M(OEt) ratio. Infra-red spectroscopic studies have shown that in the solid state 5-hydroxy-l,2-benzoquinone 2-oxime (hqoH,), 5-hydroxy-3-methyl-l,2-benzoquinone 2-oxime (3-MehqoH2), 5-hydroxy-6-methyl-l,2-benzoquinone 2-oxime (e-MehqoH,) and H-acetyl-5-amino- 1,2-benzoquinone 2-oxime (N-AcqoH) and their sodium and potassium complexes exist in the oximic form rather than the nitroso form. Nuclear magnetic resonance studies have also shown that in d,-DHSO solution hqoH,, 3-MehqoH, and 6-MehqoH} and their sodium complexes exist in one form only which is oximic in character. However, in DjO the results for the sodium complexes of hqoH, and e-MeqoH, indicate the presence of at least two species. In the case of the sodium 5-hydroxy-6-methyl-l,2-benzoquinone 2-oximate these species are oximic in character. An X-ray crystallographic study of e-HehqoH, has shown that in the solid state this compound exists in the 1,4- rather than the 1,2-quinone 2-oxlmic form. The synthesis of iron(II) complexes of hqoH,, 3-MehqoH] and 6-HehqoH] using the direct and the nitrosation methods was examined. The direct method gave rise to the complexes Fe(hqoH), OHjO, Fe(3-HehqoH), and Fe(6-MehqoH)2 '2H20 whereas the nitrosation method gave rise to ill-defined solids. Na[Fe(N-Acqo), ]-4H20 was obtained by nitrosation of N-acetyl-3-aminopnenol in the presence of Iron(II) ammonium sulphate. Hossbauer and magnetic studies indicate that Na[Fe(N-Acqo)j]-4H20 is a low spin iron(II) complex whereas the bischelates have properties indicative of the S - 1 spin state. In-vlvo assesment of the iron chelating ability of hqoHj, 3-MehqoH2, 6-MehqoH2, N-AcqoH , N,N-dimethyl-5- amino-1,2-benzoquinone 2-oxime and violuric acid was carried out using a normal rat model. The chelators hqoH, and 6-HehqoH2were found to be effective in removing iron when administered intra-muscularly but they also caused the excretion of magnesium. Their activity was lower than that of desferrioxamine and neither was effective when administered orally.

Texto completo da fonte
Resumo:

Optical activity is typically first introduced to a prospective chemist in her sophomore year organic chemistry course. Here, she is taught that optical activity is a consequence of chirality, for example, L-tartaric acid has a specific rotation of +12° at the sodium D-line. However, this leaves said chemist with a wildly skewed and rather vague understanding of the concept of optical activity. There are two major problems with the current understanding of optical activity. The first is that both theory and experiment have shown that optical activity is, in fact, not a consequence of chirality. Molecules belonging to one of four achiral point groups (Cs, C2 v, S4, and D 2d) can display optical activity in particular directions. However, measurement requires an anisotropic medium which presents major challenges. The second problem is that we lack structure-property relationships; specific rotations generally speaking are impossible to connect to molecular structure. Herein, we emphasize optical activity in achiral molecules whose high symmetry and simplified electronic structure are used to establish structure–property relationships. First, achiral optical activity is emphasized by showing that achiral polyaromatic hydrocarbons (PAH) are actually significantly more optically active than their helicene isomers. Next, small, planar, conjugated hydrocarbons are used to interpret optical activity by analysis of their π wave functions that can be intuited from structure. Finally, it is shown that aromaticity is generally deleterious for optical activity. A simple explanation is offered based on Kekule structures.

Dear Reader, the newly born AsiaChem magazine echoes the voice of the Federation of Asian Chemical Societies (FACS). We believe that this biannual, free-access magazine will attract worldwide attention because it comprises diverse articles on cutting-edge science, history, essays, interviews, and anything that would interest the broad readership within the chemical sciences. All articles are authored by scientists who were born in Asian countries or actively working in Asia. Thus, eight FACS countries, including Australia, China, India, Israel, Jordan, South Korea, Taiwan, and Turkey, are represented in this inaugural issue.

Resumo:
The purpose of this article is to analyze the current trends in the use of the augmented reality in the chemistry education and to identify the promising areas for the introduction of AR-technologies to support the chemistry education in Ukrainian educational institutions. The article is aimed at solving such problems as: the generalization and analysis of the scientific researches results on the use of the augmented reality in the chemistry education, the characteristics of the modern AR-tools in the chemistry education and the forecasting of some possible areas of the development and improvement of the Ukrainian tools of the augmented reality in the chemistry education. The object of research is the augmented reality, and the subject is the use of the augmented reality in the chemistry learning. As a result of the study, it has been found that AR-technologies are actively used in the chemistry education and their effectiveness has been proven, but there are still no Ukrainian software products in this field. Frequently AR-technologies of the chemistry education are used for 3D visualization of the structure of atoms, molecules, crystalline lattices. The study has made it possible to conclude that there is a significant demand for the chemistry education with the augmented reality that is available via the mobile devices, and accordingly the need to develop the appropriate tools to support the chemistry education at schools and universities. The most promising thing is the development of methodological recommendations for the implementation of laboratory works, textbooks, popular scientific literature on chemistry with the use of the augmented reality technologies and the creation of the simulators for working with the chemical equipment and utensils using the augmented reality.
