Abstract:

The title compounds (3) and (4) have been generated at low temperature by debromosilylation of 1-bromo-6-trimethylsilylbicyclo[4.1.0]hept-3-ene-2,5-dione (23) and 1a-bromo-7a-trimethylsilyl-1a,7a-dihydro-1H-cyclopropa[b]naphthalene-2,7-dione (38) respectively. Both cyclopropa-fused quinones are reactive but each could be trapped with furan to give a pair of cycloadducts, which were remarkably resistant to cycloreversion. In the absence of added trapping agent, the cyclopropanaphthoquinone (4) was intercepted by fluoride ion to give 1a-fluoro-1a,7a-dihydro-1H-cyclopropa[b]naphthalene-2,7-dione (39) in low yield. These findings indicate that the quinones (3) and (4) do not behave like cycloproparenes but still possess much of the reactivity inherent in the strained bicyclo[4.1.0]hept-1(6)-ene system (32). Theoretical calculations at the Becke3LYP/6-31G* level have been carried out on (3) and the isomeric structures bicyclo[4.1.0]hepta-1,5-diene-3,4-dione (1) and bicyclo[4.1.0]hepta-1(6),4-diene-2,3-dione (2); these reveal that (2) and (3) lie 78·7 and 58·6 kJ/mol respectively above (1).

Abstract:

The (1α,2β,3α,6α)-2,3,7,7-tetrahalobicyclo[4.1.0]heptanes (8a-c), whose structures have been determined by X-ray methods, give 2-halobicyclo[4.1.0]hepta-1,3,5-trienes (5) upon dehydrohalogenation. The 'mixed' halide (8c) and partly labelled [7-13c]-(8b,c) have revealed the presence of competing pathways in these conversions. By comparison, dehydrohalogenations of the (1α,3α,4β,6α)-3,4,7,7-tetrahalobicyclo[4.1.0]heptanes (3) give unrearranged 3-halobicyclo[4.1.0]-hepta-1,3,5-trienes (4).

Abstract:

Novel class of the carbocyclic nucleosides based on bicyclo[2.2.1]heptene/heptane was prepared by two approaches. Thymine analogues were synthesized starting from methyl (1R*,4S*)-bicyclo[2.2.1]hepta-2,5-diene-2-carboxylate1by Michael addition of the thymine salt to the double bond as the key step. The yield and ratio of the isomers of this reaction depended on the used base (DBU, K2CO3). Purine nucleoside analogues were synthesized by the linear synthesis, the purine nucleobase was build-up on the amino group. The amino groups (exo/endoconfiguration) were introduced to the scaffold by the Curtius rearrangement. Norbornene analogues were converted to saturated andcis-hydroxylated nucleoside derivatives. [(1R*,2S*,3S*,4S*)-3-(6-Chloro-9H-purin-9-yl)bicyclo[2.2.1]hept-5-en-2-yl]methanol (13a) and [(1R*,2R*,3R*,4S*)-3-(6-chloro-9H-purin-9-yl)bicyclo[2.2.1]hept-5-en-2-yl]methanol (13b) showed moderate activity againstCoxsackievirus CVB3.

Abstract:

Hepta-O-acetyl-O-α-D-Rhap-(1 → 3)-O-α-D-Rhap-(1 → 2)-glycerol (5) was the major component derived by way of Smith degradation of A-band polysaccharide (a D-rhamnan isolated from a mutant, AK1401, of Pseudomonas aeruginosa strain PAO1). The structure has been verified by an unambiguous synthesis of 5. Based on mass spectrometric evidence, hepta-O-acetyl-O-Ribp-(1 → 3)-O-α-D-Rhap-(1 → 2)-glycerol is considered to be one of the minor components. The Smith degradation of A-band polysaccharide and the synthesis of 5 are reported.

Abstract:

Depuis plusieurs années, notre équipe s’intéresse à l’utilisation d’une résine portant des groupes furyles dans diverses stratégies « traceless ». Cette stratégie implique une étape d’accrochage de diénophiles acétyléniques par réaction de Diels-Alder et de décrochage de la résine par réaction rétro-Diels-Alder thermique après fonctionnalisation de l’adduit de cycloaddition. Différentes fonctionnalisations ont déjà été réalisées. Dans un premier temps, nous avons abordé la préparation de dérivés 7-oxa-bicyclo[2. 2. 1]hepta-2,5-diéniques par réaction de Diels-Alder entre des composés acétyléniques et 2-[4-(benzyloxy)phénylméthyl]furane (analogue en solution de l’attache furanique présentée sur la résine). Dans un second temps, nous avons étudié la réactivité d’ylures d’azométhines avec ces 7-oxabicyclo[2. 2. 1]hepta-2,5-diènes dans diverses conditions. Ceci nous a permis d’obtenir des pyrrolidines par cycloaddition 1,3-dipolaire et des 3-(aminobenzyl)-7 oxabicycloheptènes. Après réaction de rétro-Diels-Alder thermique il a été possible d’accéder à diverses pyrrolines et a des dérivés d’allylamine. Les 3-pyrrolines ainsi obtenues ont pu être oxydé en 2H-pyrroles. Dans une dernière partie, nous avons décrit les premiers essais de réaction des 7-oxabicyclo[2. 2. 1]hepta-2,5-diènes avec des nitrones. Nous avons obtenu, par réaction 1,3 dipolaire, des isoxazolidines qui après réaction de rétro-Diels-Alder thermique ont conduit à des isoxazolines<br>First, we approached the preparation of 7-oxa-bicyclo[2. 2. 1]hepta-,5-dienic derivatives by Diels-Alde reaction between acetylenic compounds and 2-[4-(benzymoxy)phenylmethyl]furane (smilar in solution of the furan presented on the resin). Then, we studied the reactivity of azomethine ylide with 7-oxabicyclo[2. 2. 1]hepta-2,5-dienes under various conditions. This lead us to obtain pyrrolidines by 1,3-dipolar cycloaddition and 3-(aminobenzyl)-7oxabicycloheptenes. After reaction of thermics retro –Diels-Alder it was possible to reach various pyrrolines and derivatives of allylamine. 2H-pyrroles were obtained by DDQ oxidation of the 3-pyrrolines. In a last part, we described the first tests of reaction of 7-oxabicyclo[2. 2. 1]hepta-2,5-diene with nitrones. We obtained by 1,3-dipolar reaction the isoxazolidines which after reaction of thermics retro-Diels-Alder led to isoxazolines

Abstract:

Retrocyclin RC-101, a θ-defensin with lectin-like properties, potently inhibits infection by many HIV-1 subtypes by binding to the heptad repeat (HR)-2 region of gp41 and preventing six-helix bundle formation. In the present study, we used in silico computational exploration to identify residues of HR2 that interacted with RC-101 and then analyzed the HIV-1 Sequence Database at LANL for residue variations in the HR1 and HR2 segments that could plausibly impart in vivo resistance. Docking RC-101 to gp41 peptides in silico confirmed its strong preference for HR2 over HR1, and implicated residues crucial for its ability to bind HR2. We mutagenized these residues in pseudotyped HIV-1 JR.FL reporter viruses, and subjected them to single round replication assays in the presence of 1.25-10ug/ml RC-101. Except for one mutant that was partially resistant to RC-101, the other pseudotyped viruses with single-site cationic mutations in HR2 manifested absent or impaired infectivity or retained wild-type susceptibility to RC-101. Overall, these data suggest that most mutations capable of rendering HIV-1 resistant to RC-101 will also exert deleterious effects on the ability of HIV-1 to initiate infections - an interesting and novel property for a potential topical microbicide.<br>M.S.<br>Department of Molecular Biology and Microbiology<br>Burnett College of Biomedical Sciences<br>Molecular and Microbiology MS

Abstract:

Le présent mémoire est divisé en quatre chapitres traitant de l’étude de la formation de composés de type bicyclo[3.2.0]hept-l(7)-én-6-one. Cette étude prend son origine dans une méthodologie que le professeur Bélanger veut éventuellement mettre sur pied et qui met en valeur une fonction relativement peu utilisée en synthèse organique, le cétène. Le premier chapitre traite de la première méthode imaginée pour la formation des composés bicyclo[3.2.0]hept-l(7)-én-6-one. Celle-ci consiste en la cycloaddition [2+2] entre un cétène et un alcyne menant à une cyclobuténone. Une particularité de cette réaction est que celle-ci est connue de façon intermoléculaire, mais la version intramoléculaire est à ce jour encore sans précédent. Afin de pouvoir appliquer cette réaction pour la formation du type de composé visé, la version intramoléculaire devait être étudiée et les résultats de cette étude sont présentés dans ce chapitre. Dans le chapitre 2, les résultats d’une étude sur des équivalents d’alcyne sont présentés. Par équivalent d’alcyne, il est entendu que les groupements fonctionnels utilisés pourraient permettre d’obtenir la cyclobuténone fusionnée non plus en une seule étape, mais bien en une séquence de réactions. Ces différentes alternatives à la fonction alcyne sont présentées selon deux perspectives. Tout d’abord, trois méthodes ont été étudiées pouvant permettre la séquence réactionnelle en cascade et ainsi avoir accès aux composés cibles dans un seul ballon de réaction et dans les mêmes conditions. Ensuite, une autre méthode est présentée consistant cette fois en une séquence de deux réactions devant, dans ce cas-ci, être effectuée en deux temps. Le troisième chapitre présente les résultats obtenus lors de l’étude de la formation d’un composé modèle de type bicyclo[3.2.0]hept-l(7)-én-6-one à partir d ’un composé de type bicyclo[3.2.0]heptan-6-one. Cette méthode consiste alors en l’oxydation d’une cyclobutanone en cyclobuténone correspondante et implique ainsi une transformation chimique formant une structure moléculaire très tendue. Enfin, il est discuté dans le dernier chapitre d’autres alternatives aux méthodes présentées dans les chapitres précédents et prenant toujours avantage de la fonction cétène. Certains résultats sommaires y sont présentés en guise d’introduction à des études éventuelles sur ces différentes méthodes.

Abstract:

Polyamines are small, polycationic molecules required for growth and development and found in all living cells. In this study, the effects of two polyamine analogues, hexamethylene bisacetamide (HMBA), a differentiation inducer, and 7-[N-(3-aminopropyl)amino] heptan-2-one (APAH), an inhibitor of N8-acetylspermidine deacetylase, were studied using quantitative proteomics and stable-isotopes. Two new technologies, isotope-coded affinity tags (ICAT) and quantification in fragment spectra using isobaric stable isotope reagents (iTRAQ) were employed and compared. Quantitative results of these experiments showed few changes in the type and level of proteins detected in whole-cell extracts. Proteins from three populations of cells were studied, control (untreated), HMBA-treated, and HMBA plus APAH treated cells. Some of the proteins that were differentially expressed in response to these agents include pyruvate kinase (PK), lactate dehydrogenase (LDH), mini-chromosome maintenance protein 3 (MCM3), and poly-rC binding protein. The proteins PK and LDH have been reported as possible cancer markers. Histone protein levels were significantly reduced on HMBA treatment, and substantially recovered with the addition of APAH. This finding was very convincing in the iTRAQ work, but invisible to the ICAT experiment, because of the lack of cysteine residues required for quantification in the ICAT methodology. Two proteins were elevated in the HMBA-APAH experiment compared to the other two, heterogeneous nuclear ribonuclear protein C1/C2 (HNRP C1/C2) and ubiquitin. Considering their unique functions, the up-regulation of these proteins suggests the involvement of internal ribosome entry and protein degradation in response to APAH. The results of the two technologies, ICAT and iTRAQ, were found to overlap, but were partly complementary.

Este trabalho relata a síntese de uma série de novos ligantes quirais (+) e (-)-syn-1,3-aminoálcoois derivados do norbornano. Através da reação de transesterificação enzimática com a lípase da Candida rugosa em acetato de vinila do álcool racêmico 7,7-dimetoxi-1,4,5,6-tetraclorobiciclo[2.2.1]heptan-5-en-2-ol, (±)-3, foram obtidos os álcoois quirais (+)-3 e (-)-3 (Esquema 1). Através da reação de redução e descloração destes álcoois com Na0/NH3/etanol foram obtidos os respectivos álcoois (+)-4 e (-)-4 (Esquema 2). Os álcoois quirais (+)-4 e (-)-4 foram utilizados como produtos de partida para a síntese dos 1,3-aminoálcoois quirais (+)-9 e (-)-9 em 5 etapas. Deste modo, a partir destes aminoálcoois (9), foi possível sintetizar 12 novos compostos (Esquema 2), todos inétidos na literatura. Os 1,3-aminoálcoois 10, 11, 13, 14 e 15 foram empregados como catalisadores quirais na adição enantiosseletiva de ZnEt2 ao benzaldeído. Excelentes rendimentos e excessos enantioméricos (até 91%) foram obtidos. A relação entre a configuração absoluta do 1-fenilpropanol com a configuração do carbono ligado ao grupo hidroxila dos ligantes foi estudada e, de acordo, com a enantiosseletividade observada foi sugerido um mecanismo para a reação Os produtos com esqueleto ciclopentila são importantes compostos com potencial atividade biológica, fazendo parte da estrutura de prostaglandinas, agentes antitumorais e inibidores da glicosidase. Portanto, nós decidimos usar o acetato clorado quiral 2 para preparar ciclopentanóides quirais altamente funcionalizados. Para isso, o acetato clorado quiral 2 foi submetido à oxidação usando uma quantidade catalítica de RuCl3 anidro na presença de NaIO4 obtendo-se a dicetona 16 (Esquema 3). A dicetona 16 foi clivada com H2O2 em meio alcalino fornecendo os diácidos 17a e 17b, que foram esterificados in situ com excesso de CH2N2 para fornecer uma mistura do hidroxi e acetoxi diéster 18 e 19, respectivamente. A redução da mistura 18 e 19 ou da mistura 17a e 17b com BH3.THF fornece a lactona 20 com excelentes rendimentos.
