Abstract:
Solvent-free, microwave-assisted synthesis of several new indolyl imidazoles of biological importance is reported. First, indoleamine was condensed with substituted aryl aldehydes to give corresponding Schiff's bases. Then, Schiff's bases were reacted with ammonium acetate and benzil using silica gel as the solid support to yield the corresponding substituted indolyl imidazole derivatives. A comparison between the conventional approach and the microwave-assisted method is also reported in this research. All the synthesized substituted indolyl imidazole derivatives showed good antibacterial activity against Gram (-ve) bacterial strains (Escherichia coli and Klebsiella pneumonia). The synthesized indolyl imidazole derivatives also showed significant anticancer activity against the Dalton's lymphoma ascites cell line..

Abstract:
Two new imidazole substituted chlorin derivatives, namely (4-[1-imidazolyl]-phenyl)-amide pyropheophorbide-a and (3-[1-imidazolyl]-propyl)-amide pyropheophorbide-a have been synthesized. Their cell viabilities on A549 human lung adenocarcinoma cells were investigated and compared with that of pyropheophorbide-a. According to the phototoxicity study, (4-[1-imidazolyl]-phenyl)-amide pyropheophorbide-a and (3-[1-imidazolyl]-propyl)-amide pyropheophorbide-a were found superior to pyropheophorbide-a with respect to high phototoxicity. This work demonstrates that imidazole substituted chlorin derivatives could be a promising candidate for photodynamic therapy and are worth further investigations.

Abstract:
In the present study, we have designed, predicted, synthesized and evaluated some new substituted imidazoles derivatives as antifungal agents. Here, a set of 26 substituted imidazole derivatives were investigated for molecular modeling studies using a combination of various molecular descriptors. A sequential multiple linear regression (SQMLR) procedure was used to model the relationships between molecular descriptors and the antifungal activity of the substituted imidazole derivatives. The QSAR analysis of the imidazole analogues furnished topology of molecules and electronic contribution are crucial for the antifungal activity. On the basis of QSAR finding a set of compounds were designed and subset was put forward for the synthesis and evaluation of antifungal activity. The present study has resulted in the identification of key molecular descriptors, which might be helpful in the optimization of the imidazole analogues as antifungal agents.

Abstract:
Antibiotics have been the cornerstone of modern medicine saving lives by virtue of being able to cure infectious diseases and to prevent infections in those who are immune compromised. Their intense use has led to a surging increase in the incidence of antibiotic-resistant bacteria resulting in a desperate need for antibiotics with new mechanisms of action. As part of our search for new antimicrobials we have screened an in-house library of compounds and identified two 3-substituted-1H-imidazol-5-yl-1H-indoles as weak growth inhibitors (MIC 16 µg/mL) against methicillin-resistant Staphylococcus aureus (MRSA). An extensive library of analogues was prepared using the Van Leusen three-component reaction, biological evaluation of which led to the identification of two analogues (26 and 32) with favorable anti-MRSA activity (MIC ≤ 0.25 µg/mL) which also lacked cytotoxic or hemolytic properties. The screening campaign also identified two derivatives, a phenethyl-indole-imidazole 57 and a 5-phenyl-1H-imidazole 111 that were non-toxic selective antifungals towards Cryptococcus neoformans. These results have identified 3-substituted-1H-imidazol-5-yl-1H-indoles and 5-phenyl-1H-imidazoles as new structural scaffolds for further investigation as anti-MRSA and anti-C. neoformans agents, respectively.

Abstract:
<em>On the basis of various literature survey, imidazole derivatives show various activity such as antimicrobial, anti-inflammatory, analgesic, antitubercular, anticancer etc. The possible improvements in the activity can be further achieved by slight modifications in the substituents on the basic imidazole nucleus. Thus imidazole offers better pharmacodynamic characteristics. Furthermore, some imidazole drugs, at high concentrations, could exert direct inhibitory effects on membranes, without interference with sterols and sterol esters. Various recent new drugs developments in imidazole derivatives show better effect and less toxicity. Prompted by the broad spectrum activities of 2, 4, 5- triphenylimidazole derivatives, it was decided to synthesize various 2, 4, 5-triphenyl-1-substituted imidazoles and to evaluate them for their biological activities.</em> <strong>Keywords:</strong><em>Triphenyl imidazole,formaldehyde, secondary amine.</em>

Abstract:
An efficient synthesis of new N-alkyl- and N-aryl-3-oxido-1H-imidazole-4-carboxamides based on exploration of inexpensive, commercially available ethyl acetoacetate, paraformaldehyde and primary amines is described. Representative compounds were tested in selected transformations, such as ‘sulfur-transfer reaction’ leading to imidazole-2-thiones and isomerization to corresponding imidazol-2-ones. Strong intramolecular hydrogen bonding via the N-oxide function results in the reduced reactivity of 3-oxido-1H-imidazole-4-carboxamides in both reactions. Moreover, the palladium catalyzed C(2)-arylation of imidazole ring as well as azide-alkyne [3+2] cycloaddition using the N-propargyl substituted 4-carboxamide derived from an imidazole 3-oxide as a dipolarophile, were also studied.

Abstract:
Thesis advisor: Mary F. Roberts<br>As the central repository of biological information and ultimate mediator of all processes underlying the activities of living organisms, nucleic acids are the sine qua non for life as we know it. Biological research over the past century and more has revealed much of the structure and function of nucleic acids, revealing in turn how life begins, changes, reproduces, and ends. We glimpse how life has become what it is and perhaps what it may become. This work seeks to understand the ramifications of altering a single nitrogen of the purine nucleoside components of nucleic acids. As will be shown, purine analogs lacking the N3 nitrogen have altered interactions with proteins, water, and other molecules. Replacement of this nitrogen with a C-H, C-CH3, or C-CH2OH functionality impacts the structure and biological interactions of a DNA duplex containing these alterations in ways not entirely foreseen when this work began over ten years ago. The synthetic effort needed to obtain purine nucleosides containing each of these modifications is significant. Along the way, new methodologies applicable both to the synthesis of purine analogs and natural purine nucleosides are described<br>Thesis (PhD) — Boston College, 2010<br>Submitted to: Boston College.

Abstract:
Les molécules basées sur les systèmes hétérocyliques imidazo[1,2-a]pyridine et imidazo[1,2-a]pyrazine ont montré une large variété d'applications thérapeutiques. Ainsi, la conception de nouveaux dérivés d'imidazo[1,2-a]pyridine, substitués en position 2 et 3, mais également d'imidazo[1,2-a]pyrazine, fonctionnalisés en position 6, a été envisagée afin d'élargir le profil d'activité pharmacologique. En particulier, les infections fongiques (Candida albicans, Aspergillus fumigatus) et les maladies parasitaires (Leishmania) représentent un problème majeur de santé publique. Plusieurs classes de composés pour le traitement de ces infections sont couramment exploitées. Cependant, leur utilisation est limitée pour des raisons de toxicité, de biodisponibilité et surtout de résistance, ce dernier aspect étant le problème majeur nécessitant la découverte de nouveaux traitements. Des résultats préliminaires avaient montré que l'emploi d'un inhibiteur spécifique de PKC et des MAP kinases fongiques restaurait la sensibilité de plusieurs souches de C. Albicans aux azolés, d'où l'intérêt de cibler cette cascade. De même, chez Leishmania une activité protéine kinase C a été démontrée. Parmi les composés testés, l'émergence d'une activité, que ce soit sur C. Albicans ou A. Fumigatus, n'a pu être observée alors que des activités prometteuses sur Leishmania major ont été établies<br>Molecules based on imidazo[1,2-a]pyridine and imidazo[1,2-a]pyrazine heterocyclic systems showed a wide variety of therapeutic applications. Thus, the design of new imidazo[1,2-a]pyridine derivatives, substituted in position 2 and 3, but also imidazo[1,2-a]pyrazine derivatives functionalized at position 6, was considered in order to expand the profile of pharmacological activity. In particular, fungal infections (Candida albicans, Aspergillus fumigatus) and parasitic diseases (Leishmania) represent a major public health problem. Several classes of compounds for the treatment of these infections are currently in clinical use. However, their use is limited for reasons of toxicity, bioavailability and especially resistance which is the major problem requiring the discovery of new treatments. Preliminary results pointed out that the use of a specific inhibitor of PKC and MAP fungal kinases restored the sensitivity of several strains of C. Albicans to azoles, hence the interest of targeting this cascade. Similarly, Leishmania protein kinase C activity has been demonstrated. Among the tested compounds, the emergence of an activity, whether on C. Albicans or A. Fumigatus, could not be observed while promising Leishmania major activities have been established

Abstract:
L'hypertension arterielle est une pathologie qui concerne plus de 10% de la population adulte. Pour son traitement, il existe toute une gamme de medicaments tres actifs repartis en plusieurs classes distinctes (les diuretiques, les bloquants, les antagonistes calciques, les inhibiteurs de l'enzyme de conversion, les antihypertenseurs centraux). Depuis quelques annees d'autres composes actifs ont ete mis en evidence qui font intervenir de nouveaux recepteurs notamment les recepteurs aux imidazolines. Le but de ce travail est de synthetiser des composes susceptibles d'avoir une activite antihypertensive centrale sans les effets secondaires de produits deja connus, grace a une bonne affinite pour les recepteurs aux imidazolines. Nos premiers travaux ont concerne la synthese de divers analogues de l'idazoxan qui possedent le motif 2,3-dihydro-1,4-benzodioxine. Cette etude a permis de mettre en evidence que pour avoir une bonne affinite pour les recepteurs imidazoliniques, le motif imidazoline etait indispensable. Par la suite, nous nous sommes interesse a la synthese de 3,4-dihydro-2h-1,4-benzoxazines diversement substituees soit par differents groupements alkyles au niveau de l'azote soit par differents groupements (methyle, chloro, methoxy) sur le noyau aromatique. Nous avons egalement considere la substitution en position alpha de l'imidazoline. Les resultats pharmacologiques ont montre que le motif 2,3-dihydro-2h-1,4-benzoxazinique judicieusement substitue permet d'obtenir une bonne affinite pour les recepteurs aux imidazolines et #2 adrenergiques. Nous avons aussi prepare des imidazolines comportant un motif benzoxazinique associe a un troisieme cycle constitue de 5,6 et 7 chainons. Ces composes sont prepares selon deux approches differentes ; l'une faisant intervenir la 7-hydroxyindoline et l'autre le 2,3-dihydro-2h-1,4-benzoxazine-2-carboxylate d'ethyle. Parmi les composes que nous avons synthetises quatre d'entre eux se distinguent par une bonne affinite vis a vis des recepteurs aux imidazolines i#2 et #2 adrenergiques. Ces composes sont aussi actifs in vivo. Ces resultats tres encourageants laissent entrevoir des developpements futurs pour mieux cerner le profil pharmacologique de ces composes.

Abstract:
碩士<br>國立交通大學<br>應用化學系<br>90<br>A series of 39, 47, 52 and 53 in 2-methyltetrahydrofuran glass matrices at 77 K were irradiated with 230-325 nm (NiSO4-filtered, UV light), which gave triplet EPR spectra, and the zero-field splitting (zfs) parameters D' values are 0.0228, 0.0225, 0.0190 and 0.0176 cm-1, respectively. At 4 K, the D' values of 51 and 47 are 0.0239 and 0.0237 cm-1, respectively. The radical pairs derived from 51 (12-44 K) and 47 (8-52 K) both showed linear Curie plots, thereby indicating either the ground state are triplets or that singlet and triplet states are degenerate (≦30 cal/mole difference). An addition product of Ts and MNP was observed when 51 was photolyzed in the presence of spin trapping agent. N-benzenesulfonyl substituted hetercyclic molecules 85 and 88 also gave triplet EPR spectra, which are consistent with triplet radical pairs. Results indicate that nitro-sulfur bonds were easily cleaved by 230-325 nm photolysis, and the results are supported by ab initio calculations. Therefore, the reported D' value (0.0226 cm-1) of a biradical by Professor Berson in the photolysis of N-tosyl pyrrole diazene 18 (J. A. Berson, J. Am. Chem. Soc. 1997, 119, 1416.) may not be a triplet biradical and could be a triplet radical pair instead.

Abstract:
This chapter investigates isoxazoles, pyrazoles, and isothiazoles. Isoxazole, pyrazole, and isothiazole are the parent structures of the 1,2-azole family of heterocycles, having a nitrogen atom plus one other heteroatom in a 1,2-relationship in a five-membered ring. The aromatic sextet is completed by delocalization of the lone pair from the second heteroatom. Consequently, as in pyridine, the nitrogen atoms of the 1,2-azoles have a lone pair available for protonation. However, the 1,2-azoles are significantly less basic than the 1,3-azoles because of the electron-withdrawing effect of the adjacent heteroatom. Isoxazole and isothiazole are essentially non-basic heterocycles, and even pyrazole is a much weaker base than the corresponding 1,3-azole imidazole. As with substituted imidazoles, substituted pyrazoles may exist as a mixture of tautomers. The chapter then looks at the synthesis, electrophilic substitution, and anion chemistry of isoxazoles, pyrazoles, and isothiazoles.

This chapter takes a closer look at losartan and valsartan which are used in reducing blood pressure. It gives a brief overview of the factors leading to the synthesis of losartan. Then it describes the two key components required for the convergent route leading to losartan: the preformed imidazole and a substituted biphenyl derivative. The chapter presents the pathways by which losartan has been prepared. It also reviews the synthesis of valsartan, which was first approved in 1996. The process involves the hydrolysis to the primary alcohol via acetate, Swern oxidation, amination with L-valine methyl ester, and acylation with valeric acid chloride, among others.

Abstract:
New molecules with promising insecticidal properties like imidazo[2,1-c][124] triazole analogs were synthesized, starting with imidacloprid and bio-assayed. The structures of synthesized molecules were confirmed with diverse modern methods like FT-IR, 1H NMR, 13C NMR, and Mass spectrometry. The synthesized molecules are screened to investigate their insecticidal and anti-bacterial activity. The bioassay screening showed that synthesized compounds chloro (3-(4-chlorophenyl)-7-[(6-chloropyridin-3-yl)methyl]-2,5,6,7-tetrahydro-3H-imidazo [2,1-c] [1,2,4] triazole (4b), the 3-(2-chlorophenyl)-7-[(6-chloropyridin-3-yl)methyl]-2,5,6,7-tetrahydro-3H-imidazo [2,1-c] [1,2,4] triazole (4c), nitro(7-[(6-chloropyridin-3-yl)methyl]-3-(4-nitrophenyl)-2,5,6,7-tetrahydro-3H-imidazo[2,1-c] [1,2,4] triazole (4d) and 7-[(6-chloropyridin-3-yl)methyl]-3-(2-nitrophenyl)-2,5,6,7-tetrahydro-3H-imidazo[2,1-c] [1,2,4]triazole (4e) showed higher bioactivities than imidacloprid against Hubner (H.armigera), Mealybugs (Planococcus citri), and Mango hoppers (Idioscopus clypealis), and tobacco and tomato bacterial wilt. The results of biological activity were determined. Compounds with electron-withdrawing groups showed potential as vector control agents.

Abstract:
Abstract This paper investigates the inhibition performance of a typical imidazoline based inhibitor under multiphase flow. Electrochemical impedance spectroscopy (EIS) measurements were carried out in a 101.6 mm I.D., 15 m long acrylic flow loop using ASTM substitute saltwater and carbon dioxide gas. This flow loop system can generate slug flow, full pipe flow and other multiphase flow patterns. Effects of different flow conditions on inhibition performance of this typical inhibitor were examined. The system was maintained at a pressure of 0.136 MPa and a temperature of 40 °C. EIS measurements for this inhibitor in a Rotating Cylinder Electrode (RCE) system were also conducted. Different equivalent circuit models were used to fit the experiment data for both the RCE and flow loop systems. The high shear stress and turbulence due to the mixing vortex and the bubble impact in multiphase flow can enhance the corrosion or reduce the inhibition performance of inhibitors.

Abstract:
In animal and human organisms, there are many enzymes, members of the family of heme- containing proteins, cytochromes P450 (CYPs), included in the biosynthesis and metabolism of many biomolecules, as cholesterol, bile acids, sex, and corticosteroid hormones, as well as in metabolism of drugs and xenobiotics. It is also well-known that different imidazole and triazole derivatives are efficient inhibitors of CYPs activity. In this study, we present in vitro screening of binding of novel androstane derivatives with tetrazole- containing substituents in position 17 to human recombinant steroid-converting CYP enzymes: CYP7A1, CYP7B1, CYP17A1, CYP19, and CYP21. Initial screening was performed using a high throughput screening approach, while the affinity of the ligands was analyzed using spectrophotometric titration. For some among tested compounds type I spectral response (substrate-like binding) for CYP7A1 selectively, while for one compound type II spectral response (inhibitor-like binding) for CYP21 were detected, with micromolar values of Kds. Interestingly, one compound with mixed spectral response was found to bind for CYP7B1, which means that there are two optimal positions of the ligand inside the protein active site. Such results could be useful in CYP-inhibiting drug development, during a fast, high-throughput screening of pharmacological potential of novel compounds, as well as in side- effects recognizing.
