Abstract:
ABSTRACT Pseudomonas sp. strain ADP utilizes the human-made s-triazine herbicide atrazine as the sole nitrogen source. The results reported here demonstrate that atrazine and the atrazine degradation intermediates N-isopropylammelide and cyanuric acid are chemoattractants for strain ADP. In addition, the nonmetabolized s-triazine ametryn was also an attractant. The chemotactic response to these s-triazines was not specifically induced during growth with atrazine, and atrazine metabolism was not required for the chemotactic response. A cured variant of strain ADP (ADP M13-2) was attracted to s-triazines, indicating that the atrazine catabolic plasmid pADP-1 is not necessary for the chemotactic response and that atrazine degradation and chemotaxis are not genetically linked. These results indicate that atrazine and related s-triazines are detected by one or more chromosomally encoded chemoreceptors in Pseudomonas sp. strain ADP. We demonstrated that Escherichia coli is attracted to the s-triazine compounds N-isopropylammelide and cyanuric acid, and an E. coli mutant lacking Tap (the pyrimidine chemoreceptor) was unable to respond to s-triazines. These data indicate that pyrimidines and triazines are detected by the same chemoreceptor (Tap) in E. coli. We showed that Pseudomonas sp. strain ADP is attracted to pyrimidines, which are the naturally occurring structures closest to triazines, and propose that chemotaxis toward s-triazines may be due to fortuitous recognition by a pyrimidine chemoreceptor in Pseudomonas sp. strain ADP. In competition assays, the presence of atrazine inhibited chemotaxis of Pseudomonas sp. strain ADP to cytosine, and cytosine inhibited chemotaxis to atrazine, suggesting that pyrimidines and s-triazines are detected by the same chemoreceptor.

Abstract:
1, 3, 5-Triazine (s-Triazine) is a versatile nucleus to design and develop potent bioactive molecules for drug discovery, particularly in cancer therapy. The aim of this review is to present the most recent trends in the field of synthetic strategies made for functionalized triazine derivatives active against cell proliferation. This review article covers the synthesis of aryl methylamino, morpholino, triamino substituted triazines, antimitotic agents coupled triazines and many more. Many 1,3,5- triazine derivatives, both hetero-fused and uncondensed, have shown remarkable antitumor activities. We have highlighted various derivatives with 1, 3, 5-triazine core targeting different kinases with an aim to help researchers for developing new 1, 3, 5-triazine derived compounds for antitumor activity.

Abstract:
S-triazines are photosynthetic inhibitors. They have been substituted with ω-aminoundecanoic acid. The coupling products have been transformed into triazine aldehydes. These compounds displace radioactive terbutryn and have inhibitory effects on photosynthesis in plants and bacteria. Triazine aldehydes were shown to be effective substrates for bacterial luciferase. A competitive assay between photosystem-II-herbicides and aldehyde-labeled triazines is discussed.

Abstract:
A serial of novel star-shaped 2,4,6-trisubstituted 1,3,5-triazine (s-triazine) dendrimers were synthesized via step-by-step nucleophilic substitution starting from 2,4,6-trichloro-1,3,5-triazine, and were characterized by1H,13C NMR, FT-IR and ESI-MS spectra. The crystal structures for 2b, 2d and 4c have been determined by X-ray diffraction analysis, which indicate that there are hydrogen bonding and short contact interactions existing in intermolecules result in forming three-dimensional network architecture. D NMR experiments demonstrate that symmetrical trialkylamino-s-triazine shows correlated rotations of its N(2-ethoxy-2-oxoethyl) groups, while unsymmetrical 2-R-4,6-bis(dialkylamino)-s-triazines display two non-equivalent N(2-ethoxy-2-oxoethyl) groups, issued from the restricted rotation about the created C(s-triazine)-N bonds, and was conformed by crystallographic data.

Abstract:
The purpose of this study was to characterize the phylogenetic and phenotypic traits of M91-3, a soil bacterium capable of mineralizing atrazine (2-chloro-4-N-isopropyl-6-N-ethyl-s-triazine). The isolate was identified as Ralstonia basilensis based on 99.5% homology of the 16S rRNA sequence and various chemotaxonomic data. The isolate used atrazine as the sole source of energy, carbon, and nitrogen. It could also use several other s-triazines as nitrogen sources. Ralstonia basilensis M91-3 was capable of denitrification, which was confirmed by gas chromatographic analysis of nitrous oxide under acetylene blockage conditions.Key words: atrazine biodegradation, denitrification, herbicide degrader, Ralstonia basilensis, triazine degradation.

Abstract:
La pharmacomudolation autour du squelette [1,2-α]-s-triazinique a permis de tirer les enseignements suivants tant sur le plan chimique que sur le plan pharmacochimique. L'étude de l'alkylation du malonate de diéthyle montre la difficulté d'obtenir un dérivé monoalkylé pur. Cette difficulté peut être résolue en jouant sur les solubilités des produits monoalkylés, diakylés et non alkylés. La fabrication des synthons dialkylés de type 2-iminobarbiurique a montré qu'ils se trouvaient préférentiellement sous la forme amino-iminique. Leur alkylation directe s'effectue sur l'azote intracyclique. La forme majoritaire devient alors la forme iminodioxo. En revanche, pour les dérivés monoalkylés, la structure donne lieu à un équilibre entre une forme bétaïnique mésomère et une forme aromatique. La synthèse de pyrimido [1,2-α] -s-triazines, par iminodiméthylation de synthons 2-iminobabituriques dialkilés, conduit à des pyrimido-s-triazines ayant un fonction imino-alcool conjuguée. Quant aux dérivés monoalkylés, ils conduisent essentiellement aux composés dans lesquels le noyau phényle est toujours substitué. La plupart des molécules essayées l'ont été sous leur forme racémique. Ces résultats se sont révélés dans le domaine des récepteurs sérotoninergiques 5-HT 1A et 5-HT 2A, adrénergique α-2A et α-2B, antifongique vis-à-vis de Microsporum canis dainsi que pour des toxicités cellulaires
The pharmacomodulation around the [1,2-α]-s-triazine skeleton, has enabled to draw the following conclusions, on the chemical and on the pharmacochemistry level. The study of the diethylmalonate alkylation shows some difficulties in obtaining a single monoalkylated derivative. Those difficulies can be sorted out by playing on the solubility of monoalkylated, diakylated and unalkylated products. The production of type 2-iminobarbituraes dialkylated synthons, has shown that, they were most often found under the amine form. Their direct alkylation operates within intracyclical nitrogen. The most likely obtainable form is then the iminodioxo form. However concerning monoalkylated derivativesn their structure is a tautomerism form, between a mesomeric betaine, and aromatic form. The pyrimido [1,2-α]-s-triazines synthesis through iminodimethylation of synthons dialkylated 2- iminobarbiturates, produces pyrimido-s-triazines with a cojugated imino-alcohol function. As to monoalkylated derivates, they mainly lead to tricyclic compounds with a mesomeric betaine structure. Whenever, the phenyl nucleus is subtituted, the study of testing reveals modest results for these compounds. Among the synthesized molecules, some have been tested under the recemic form. These results have been noticed with serotonergic 5-HT 1A, 5 -HT2 A, adrenergic α-2A and α-2B receptors and fungicidal against Microsporum canis and also cellular toxicities

Abstract:
Dans le but d'améliorer la biodisponibilité et optimiser les propriétés pharmacologiques des composés pyrimido [1, 2-α] et [3,4-α] - s- triazines, un aminoacide qui leur confère une potentielle compatibilité avec les milieux biologiques, a été introduit sur leur squelette s-triazinique. Deux stratégies de synthèse ont été réalisées afin d'accéder aux pharmacophores portant un aminoacide protégé. La première met en oeuvre l'introduction d'un aminoacide protégé sur la fonction acide carboxylique activée des squelettes N-phénylpyrimodo [1,2-α] et [3,4-α]-s-triazines. L'activation est réalisée dans un premier temps avec les composés DCCI/ HOBt qi sont à l'origine d'impuretés difficiles à éliminer. Nous avons améliorer les résultats en utilisant un autre auxiliaire nucléophile qui est la CDMT. La deuxième stratégie de synthèse met en oeuvre la réaction d'iminodiméthylation sur les synthons aminopyrimidinedione et acylurée utilisant une amine aromatique apportant l'aminoacide protégé. 72 pyrimido [1,2-α] et [3,4-α] -s-triazines portant un aminoacide protégé ont été synthétisées. L'introduction des aminoacides a mis en évidence l'instabilité des composés pyrimido [1,2-α] et [3,4-α]-s-triazines qui se manifeste particulièrement lors de l'étape de déprotection des aminoacides protégés
The aim of the work was to improve the biodisponibility an the pharmacological properties of pyramido [1,2-α] and [3,4-α] - s-triazines by introducing an aminoacid on the triazines nucleus. Two synthetic pathways were designed to access to compound bearing an aminoacid. The first one consists in introducing a protected aminoacid on the activited carboxylic function of pharmacophores N-phenylpyrimido [1,2-α] and [3,4-α] -s-triazines. In a first time, activation was realised by DCCI/ HOBt, but this process generated side products which were difficult to separate. Another nucleophile auxiliary ; CDMT gave better results avoiding side products an improving the yields. The second strategy consisted in iminodimethylation of aminopyrimidinedione synthons using an aromatic amine bearing the protected aminoacid. 72 pyrimido [1,2-α] and [3,4-α]-s-triazines bearing protected aminoacid could be synthesized. The instability of these compounds was specilally observed, during the deprotecting experiments

Abstract:
Les travaux réalisés dans le cadre de la thèse avaient pour but la synthèse de nouveaux fluorophores basés sur les unités BODIPYs et hydroxyphényl-s-triazines. Pour être utilisées comme sondes efficaces dans des applications en chimie et en biologie, les chromophores doivent présenter une forte brillance et des rendements quantiques de fluorescence élevés, une modulation aisée de ses propriétés optiques ainsi qu'une bonne stabilité chimique et photochimique. Une stratégie originale et efficace a été développée pour l'obtention de dérivés d'o-hydroxyphényl-s-triazine. Ces derniers présentent des déplacements de Stokes anormalement élevés ayant pour origine un transfert de proton intramoléculaire ultrarapide à l'état excité (ESIPT). L'extension du système π-conjugué sur les différentes plateformes de départ a été réalisée par couplages pallado-catalysés et/ou condensation de Knoevenagel, permettant ainsi d'accéder à une large gamme spectrale en absorption et en émission. Le développement d'une nouvelle voie de synthèse à permis l'obtention d'oligo-BODIPYs par couplage oxydant réalisé en associant PIFA et un acide de Lewis. Toutes les propriétés photophysiques des nouvelles sondes ont été étudiées et ont fait l'objet de discussions détaillées.

Abstract:
L'iminodiméthylation de six monoalkyl ou dialkyl 5-aminopyrimidine-l,3-diones par différentes amines primaires fait l'objet de cette étude. La préparation de ces synthons est réalisée à partir de cyanacétates d'éthyles, préalablement alkylés en position 2, qui réagissent avec l'urée, en milieu alcalin. L'alkylation de méthylènes fortement activés qui sont situés entre une fonction nitrile et un groupement ester, en milieu alcalin, conduit à un mélange de dérivés non alkylé, monoalkylé et dialkylé. Il s'est avéré nécessaire d'utiliser les différences de solubilité des sels de ces composés pour les séparer. Dans le but d'éviter ces difficultés, deux autres procédés de synthèse ont été utilisés. L'iminodiméthylation des synthons 5 dialkyl-6-aminopyrimidine-l,3-dione a conduit à 24 octahydropyrimido[3,4-a]-s-triazines, diversement dialkylées qui ont été soumises à un triage pharmacologique automatisé, orienté en particulier dans le domaine antimicrobien. Une série de 23 pyrimido[3,4-a]-s-triazines monoalkylées sur le sommet 9 ont été préparées par iminodiméthylation de 5-monoalkyl-6-aminopyrimidine-1,3-diones. Il a été montré que la structure de ces composés étant triazinique et non pyrimido pyrimidinique comme cela aurait pu être le cas. Ces composés, en dépit d'un bon recouvrement structural avec la Kétansérine, un anti 5-HT2 bien connu, n'ont fait preuve que d'une faible activité dans les conditions de l'essai automatisé
Iminodimethylation of 6 monoalkyl and dialkyl 5-aminopyrimidinediones by various primary amines was studied. The synthesis of these synthons was performed from ethyl cyanacetates, previously alkylated in 2 position, which reacted with area in alkaline medium. Alkylation of the strongly activated methylenes, situated between a nitrile and an ester groupe, in alkaline medium, leads to a mixture of unalkylated, monoalkylated and dialkylated derivatives. It was then necessary to use the différences of solubilities of the salts of theses compounds to separated them. In order to avoid these difficulties, two other synthetic pathways were used. Iminodimethylation of these synthons yielded 24 octahydropyrimido[3,4-a]-s­triazines, variously dialkylated, which were submitted to an automated pharmacological screening, especially in the area of antimicrobial agents. A series of 23 pyrimido[3,4-a]-s-triazines monoalkylated in position 9 were synthetized by iminodimethylation of 5-monoalkyl-6-aminopyrimidine 1,3-diones. It was shown that the structure was triazinic and not pyrimido pyrimidinic as it could have been. These compounds, despite a good overlay with Ketanserin, a well known anti 5-HT2, only showed a weak activity in automated screening

Abstract:
La cathepsine (Cat) S est une protéase ciblée pour le développement de médicaments utilisés dans les maladies auto-immunes ou la douleur neuropathique. Elle joue également un rôle clé durant l’emphysème compte tenu de ses propriétés élastinolytiques. La Cat K, qui est une collagénase impliquée dans la résorption osseuse, représente une cible pertinente dans le traitement de l’ostéoporose et des métastases osseuses. De plus ces deux protéases sont des protagonistes majeurs du remodelage matriciel et l’homéostasie pulmonaire. Lors de la BPCO, la dégradation tissulaire bronchique est associée à une réaction inflammatoire qui s’accompagne d’un stress oxydatif et d’un déséquilibre de la balance protéases/antiprotéases. L'exposition à la fumée de cigarette constitue le principal facteur de risque dans la BPCO. Malgré la présence d'une cystéine nucléophile (Cys25) dans son site actif, nous avons constaté que la Cat S conserve partiellement son activité enzymatique après exposition à la fumée de cigarette. Ainsi, nous avons exploré les mécanismes soutenant la stabilité de la Cat S, en présence d’oxydants majeurs de la fumée de cigarette : peroxyde d’hydrogène, formaldéhyde, acroléine et peroxynitrite. Par ailleurs, dans le but de réguler l'activité des cathepsines à cystéine K et S, nous avons développé des inhibiteurs pseudopeptidiques de nouvelle génération dérivés de séquences substrats des cathepsines S et K ainsi que des dérivés triazines
Cathepsin (Cat) S is an attractive target for drugs in autoimmune diseases or neuropathic pain. Moreover Cat S plays a key role during emphysema according to its potent elastinolytic activity. Cat K is a critical bone-resorbing collagenase and is a relevant target for the treatment of osteoporosis and bone metastasis. Both enzymes play a key role in matrix remodeling and pulmonary homeostasis. During COPD, the degradation of pulmonary parenchyma depends on inflammatory reactions associated with oxidative stress and proteases/antiproteases imbalance. Exposure to cigarette smoke, a major source of oxidants, is the main risk factor for COPD. Despite the presence of a nucleophilic cysteine (Cys25) within its active site, we found that CatS preserved partially its proteolytic activity after exposure to cigarette smoke extract (CSE). Thus, we have explored molecular mechanisms supporting this stability in the presence of selected major CSE oxidants: hydrogen peroxide, formaldehyde, acrolein and peroxynitrite. In the other hand, we have designed innovative pseudopeptidic inhibitors derived from selective substrates of cathepsin S and K as well triazine derivatives in order to regulate the activity of cathepsins K and S

Abstract:
The presence of hydrogen sulfide (H2S) gas occurs naturally, or can be introduced via bacteria contamination, in oil and gas reservoirs worldwide. There are several options for the removal of H2S from produced oil and gas ranging from fixed assets that scrub H2S to chemical injection at the wellsite. The area of interest for many operators is in the continuous application of non-reversible chemical H2S scavengers as an easy, reliable and cost-effective solution. The majority of the non-reversible chemical H2S scavenger market is based on triazine technology derived from the reaction products of formaldehyde and amines. In recent past, there has been an active industry wide search to improve the overall performance of H2S scavengers. Major topics for improvement include: Increased H2S scavenging capacityReduction of nitrogen contamination of crude oilReduction of scale formationElimination of by-product depositionAddressing existing environmental, health and safety concernsMinimization of products/reaction by-products disposal Conversely, some of the biggest hurdles with new H2S scavengers are ensuring fast kinetic reaction rates, system compatibility, consumption rates, minimal precipitation of scavenger/by-products, scalable manufacturing and competitive economics. Many new products have been proposed by chemical manufactures but often are not able to deliver enough benefits to warrant a change from the industry standard triazine. One potential solution is to pull through a technology from a different industry that already has established production, in significant volumes, for use in oilfield applications. Ideally, the new product would offer better performance versus the incumbent, a reduction in nitrogen content and minimize solids formation and deposition. A product identified several years ago as a potential replacement was an oxazolidine derivative referred to as MBO (3,3’-methylenebis(5-methyloxazolidine)). However, MBO has had limited application in the field until recently. MBO offers some of the same benefits as triazine but outperforms the incumbent technology by increasing the consumption of H2S per mole of scavenger, reducing the nitrogen content in crude oil, reducing the by-product deposition potential. Moreover, MBO is already produced in large manufacturing quantities. In this paper we will discuss details about the chemistry and increased formaldehyde content, laboratory results related to performance, system compatibilities, decreased transportation cost and confirmation of field application on large scale that supports the usage of this alternative H2S scavenger to standard triazine. H2S scavengers are used to mitigate the risks presented by H2S. They react with H2S in the liquid phase to form non-hazardous, non-reactive species that are often water soluble and thus disposed with water. Monoethanolamine (MEA) triazine (hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine) is the most widely used scavenger. It is less toxic than most aldehyde scavengers and reacts very quickly with H2S. MEA triazine reacts irreversibly with H2S to form dithiazine (5-hydroxyethylhexahydrodithiazine). One of the major concerns with MEA triazine is that there is a strong possibility of the by-product MEA reacting with excess H2S to form an ethanolammonium sulfide species that in turn reacts with the dithiazine to form a largely insoluble polymer, commonly referred to as amorphous dithiazine. An alternative triazine used in oil and gas production is monomethylamine (MMA) triazine (1,3,5-trimethyl hexahydro-s-triazine). MMA triazine has greater volatility than MEA triazine so is more suitable for dry gas applications. In the cases on MEA triazine and MMA triazine the ratio to amine:formaldehyde is 1:1.

Abstract:
Abstract Stacked-chip scale package (S-CSP) is a new packaging technology introduced in the memory components market to effect chip miniaturization, a challenging trend in semiconductor assembly. The package is built by molding two stacked dice (Flash and SRAM) on bismaleimide triazine (BT) substrate. As this novel packaging technology offers solution to the challenge, it also poses complexity in the field of failure analysis in cases that the bottom die is the interest. Deprocessing these stacked dice while maintaining the functionality of the bottom die will be explained in detail. Prior the conduct of failure analysis (FA) and fault isolation (FI), deprocessing the failing unit containing only one die normally consists of chemical decapsulation. S-CSP sample preparation also adheres to this treatment in case the top die is the aim for analysis. On the other hand, if the concern shifts to the bottom die, sequential techniques involving precision polishing to die-to-die adhesive layer, chemical etching of adhesive and residual molding compound, and rebonding the bottom die on ceramic interposer, are employed. With the rebonded S-CSP bottom die, fault isolation could be performed further. This paper will also feature the mechanism behind the blown-up failure, a power test failure in memory devices, encountered during the package development when two types of die-to-die adhesives were selected and used. Consistent with the results of electrical characterization suggesting that S-CSP bottom die as the failing die, passivation damage is uncovered on the bottom die upon separation of the stacked dice. Material comparison points out that the hard, angular glass fillers of the die-to-die adhesive induce the damage. Polymer-filled adhesive performs better than the glass-filled adhesive as indicated by the results of the package characterization. Generally, this case exemplifies a packaging material-related failure. Moreover, the paper could serve as a reference material in the event that feasibility of packaging non-memory components in S-CSP is to be evaluated. The developed methodology of recovering the S-CSP bottom die would be a keystone in proacting for its FA readiness.

Abstract:
We built three successive versions of a thermal decomposition cavity ring-down spectrometer and tested their response to explosives. These explosive compound analyzers successfully detected nitroglycerine, 2,4,6-trinitrotoluene (TNT), pentaerythryl tetranitrate, hexahydro-1,3,5-trinitro-s-triazine and triacetone triperoxide (TATP). We determined the pathlength and limits of detection for each, with the best limit of detection being 13 parts per trillion (ppt) of TNT. For most of the explosive tests, the peak height was higher than the expected value, meaning that peroxy radical chain propagation was occurring with each of the explosives and not just the peroxide TATP.
