Abstract:
In order to study the possibility of enriching jet fuels with diamond-type hydrocarbons to improve their physico-chemical and operational properties, a catalyse with aluminum bromide of narrow 10-degree fractions of marine oil in the range of 190–250°С was carried out. Catalysis products were selected at different times and analysed by chromatomass spectrometry. It is shown that during catalysis there is a complete disappearance of non-adamanthane hydrocarbons and "naphthene background" on mass chromatograms with m/z 135, 149, 163 and 177, with the formation of new, mainly thermodynamically weakly stable isomers of adamantanes, and in subsequent It was found that from the narrow fractions of oil 230–240 and 240–250°C, where there are no hydrocarbons of the series of adamantane series, hydrocarbons of the C12–C14 form from the "naphthene background". It is suggested that transalkylation is the reason for the formation of high-molecular adamantans from low-molecular ones.

Abstract:
Understanding the host–guest chemistry of α-/β-/γ- cyclodextrins (CDs) and a wide range of organic species are fundamentally attractive, and are finding broad contemporary applications toward developing efficient drug delivery systems. With the widely used β-CD as the host, we herein demonstrate that its inclusion behaviors toward an array of six simple and bio-conjugatable adamantane derivatives, namely, 1-adamantanol (adm-1-OH), 2-adamantanol (adm-2-OH), adamantan-1-amine (adm-1-NH2), 1-adamantanecarboxylic acid (adm-1-COOH), 1,3-adamantanedicarboxylic acid (adm-1,3-diCOOH), and 2-[3-(carboxymethyl)-1-adamantyl]acetic acid (adm-1,3-diCH2COOH), offer inclusion adducts with diverse adamantane-to-CD ratios and spatial guest locations. In all six cases, β-CD crystallizes as a pair supported by face-to-face hydrogen bonding between hydroxyl groups on C2 and C3 and their adjacent equivalents, giving rise to a truncated-cone-shaped cavity to accommodate one, two, or three adamantane derivatives. These inclusion complexes can be terminated as (adm-1-OH)2⊂CD2 (1, 2:2), (adm-2-OH)3⊂CD2 (2, 3:2), (adm-1-NH2)3⊂CD2 (3, 3:2), (adm-1-COOH)2⊂CD2 (4, 2:2), (adm-1,3-diCOOH)⊂CD2 (5, 1:2), and (adm-1,3-diCH2COOH)⊂CD2 (6, 1:2). This work may shed light on the design of nanomedicine with hierarchical structures, mediated by delicate cyclodextrin-based hosts and adamantane-appended drugs as the guests.

Abstract:
Herein, the synthesis of a novel adamantanyl-functionalized phthalimide scaffold is demonstrated. The novel compound could be used as a precursor for various synthetic pathways owing to the generic use of adamantane substituents as the driving force for supramolecular interactions with macrocycles and N-substituted phthalimide derivatives as a core structure in numerous drugs. The adamantanyl-functionalized phthalimide scaffold contains bromide groups on the C4 and C5 positions of the benzene ring, effectively allowing further facile modifications of the scaffold. The structure was fully characterized including single-crystal X-ray crystallography. The crystal structure shows an adamantane moiety at an angle of 115.57(7)° to the phthalimide core, hence sterically freeing the adamantane unit for host–guest interactions.

In this study, the structural geometry and vibrational frequencies (IR) of 1,3-Diaza-adamantane-6-ones derivatives including Adamantane (A), 1,3-Diaza-adamantan (D), 1,3-Diaza-adamantan-6-one (DO), 5-Benzyl-1,3-diaza-adamantan-6-one (BD), 5-(4-Hydroxybenzyl)-1,3-diaza-adamantan-6-one (HBD), 5-(4-Methoxybenzyl)-1,3-diaza-adamantan-6-one (MBD), and 5-(4-Hydroxy-3-methoxybenzyl)-1,3-diaza-adamantan-6-one (HMBD) were theoretically studied. In addition, molecular orbital energies, including the highest occupied molecular orbitals (HOMOs), and lowest unoccupied molecular orbitals (LUMOs), and electronic properties of the titled molecules were theoretically studied using the computational method. Optimized molecular structures were obtained by DFT method with the hybrid B3LYP functional at a relatively small basis set of 6-31G. The calculated vibrational wavenumbers were obtained using the same level of the theory mentioned above. The contributions to the molecular orbitals of adamantane and substituted-phenyl groups in the title compounds were determined. Moving from A to HMBD, a decrease in the value of LUMO and total energy are noticed, while an increase in the value of HOMO is noted. These findings are supported by the decreasing in the EHOMO-LUMO gap values. Furthermore, a decrease in the value of ionization potential (IP) is obtained, while an increase in the electronegativity (EA) is observed.

We present a new method for the selective C(sp3)–H cyanation of adamantane derivatives with PINO as the hydrogen abstracting reagent. A cyano radical is thereby transferred from p -toluenesulfonyl cyanide, allowing the cyanation of adamantane derivatives in up to 71% yield. The protocol presents a novel way to orthogonally functionalized adamantanes that are otherwise difficult to prepare. Mechanistic studies support the hypothesis of a radical pathway.

Abstract:
The paraffin–naphthenic fractions (with boiling points below 310°C) prepared from three high-viscosity naphthenic crude oils, classified as types B1 and B2 (according to Petrov’s classification), were subjected to thiocarbamide complexation. The molecular composition of polycyclic hydrocarbon biomarkers and C11–C13 adamantanes in the oil samples suggested a predominantly marine genotype of the precursor organic matter (OM). The molecular composition also suggested source rocks of a clayey type. Nonetheless, the biomarkers detected in one sample indicated some contribution of terrigenous components to the precursor OM. All the oils were generated under the conditions of the main oil generation zone and, presumably, underwent microbial transformations in the deposits. The compositions of C10–C14 adamantanes in the initial paraffin–naphthenic fraction, in the thiocarbamide adduct, and in the filtrate that remained after the adduction were comparatively characterized for each oil sample. The test conditions allowed us to have adamantane more than 100-fold concentrated (in the adduct), to quantify it in the oils, and to evaluate the concentrations of C11–C14 alkyladamantanes in the oils using adamantane as an internal standard. C10–C14 adamantanes exhibited selective adduction ability, with the extraction ratios of individual components being different. Taking into account these extraction ratios, the component concentrations were evaluated on crude oil basis: 2.7 to 7.6×10–3 wt % for adamantane and 87 to 267×10–3 wt % for total C10–C14 adamantanes. The identification of adamantanes in the initial paraffin–naphthenic fractions, adducts, and filtrates revealed the presence of some other tricyclanes (probable precursors of alkyladamantanes) as well as decaline homologues. Like adamantanes, these compounds exhibited selective ability to complex with thiocarbamide.

Abstract:
The photoluminescence properties of pristine adamantane molecule have been calculated by time-dependent density functional theory (TD-DFT) within the hybrid functional level. This study aims to investigate the luminescence properties of the pristine adamantane molecule and its functionalized with neutral and ion of alkali metal to form C10H16-nXn structure (where X is Li, Li+, Na and Na+ atoms, n=1). The electronic gap of the pristine adamantane (7.15 eV) is too wide, leading to an insulator property. While all the functionalized adamantanes exhibit semiconducting behavior. The absorption and emission energies of the original structure are 6.51 eV and 5.63 eV, respectively which are in good agreement with experimental results. The pure adamantane exhibits a broad photoluminescence peak in the ultraviolet region (UV). The Stokes shift of the transition between vertical and emission is 0.88 eV which agrees well with the previous work that measures the Stokes shift of 0.7 eV. The modification of adamantane indicates that the absorption and emission gaps substantially decreases. Substituting with alkali metal causes the photoluminescence onset can be shifted from the UV to the near-IR region. These results suggest that pure and the alkali metal functionalized adamantane molecules are promoting as candidate materials for the opto-electronic applications in the ultraviolet to infrared spectral regions.

ENGLISH ABSTRACT: This study concerns the incorporation of adamantane containing monomers 3-(1-adamantyl)-1-propene and 1-(1-adamantyl)-4-vinylbenzene into ethene, propene and higher a-olefins using different catalytic systems. The effect of the incorporation of the adamantane monomer on the physical and thermal properties of the polymers was investigated. A thorough study on the background of adamantane in general, as well as polymerization reactions involving the above-mentioned monomers and a-olefins was done. 3-(1-Adamantyl)-1-propene as well as 1,.(1-adamantyl)-4-vinylbenzene was sucessfully synthesized. The homo polymers of each monomer were made. The above-mentioned monomers were also polymerized: • . 3-( 1-adamantyl)-1-propene with ethene, propene and higher a-olefins, • 1-(1-adamantyl)-4-vinylbenzene with ethene and styrene. The copolymers of 3-(1-adamantyl)-propene as well as 1-(1-adamantyl)- 4-vinylbenzene were characterized as far as possible to show the influence of the incorporation of the adamantane group on the physical and chemical properties of the polymers. A series of 3-phenyl-1-propene copolymers with higher a-olefins were synthesized to compare the influence of the phenyl group to the adamantyl group on the relevant properties of the polymers.

Abstract:
Les polymères synthétiques tels que les dendrons ou les dendrimères possèdent des propriétés structurales intéressantes. Leur monodispersité et leur synthèse étape par étape permet de contrôler et de caractériser totalement leur structure. De plus, la multivalence offre aux vecteurs une meilleure affinité d’interactions entre plusieurs copies d’un ligand lié au dendron/dendrimère et le récepteur désiré en comparaison au ligand seul. L’adamantane est une molécule rigide et stable dont plusieurs dérivés ont été commercialisés pour des applications thérapeutiques, principalement comme agents antiviraux. De plus, il est possible de le fonctionnaliser sur 4 positions symétriques via des synthèses organiques. Sa conformation 3D permet d’amoindrir les encombrements stériques entre les groupements fonctionnels. Nous avons alors choisi de combiner les propriétés de l’adamantane et des dendrons afin de construire de nouveaux vecteurs synthétiques. Leurs synthèses s’effectuent avec de hauts rendements et chaque nouveau composé a été totalement caractérisé par les différentes techniques d’analyses chimiques et structurales. Les dendrons à base d’adamantane polycationiques non cytotoxiques ont révélé une forte pénétration cellulaire permettant de mieux comprendre les mécanismes d’internalisation des dendrons. Ils ont également été évalués pour la formation de complexes avec un plasmide d’ADN. Des modifications sur leurs structures ont amélioré leur capacité à interagir avec l’acide nucléique grâce à la modification du point focal. Enfin, un peptide thérapeutique aux propriétés protectrices dans le lupus érythémateux disséminé, P140, a été couplé à un dendron à base d’adamantane à 3 branches et nous avons analysé les effets biologiques du trimère en comparaison avec le monomère
Dendrons (wedge-shaped dendrimer sections) have been investigated as ideal nanoscale carrier molecules for the delivery of bioactive materials into the cells. Molecular engineering of these hyperbranched, monodisperse, well-defined structures can be easily performed using simple organic synthesis. Multivalency constituted by the multiple surface groups at the periphery of a dendron promotes higher binding affinity for ligand/receptor interactions. Adamantane molecule is a rigid structure consisting of four cyclohexane rings fused in chair conformation. The well-defined 3D conformation, the hydrophobicity and the lipophilicity provide to adamantane-based compounds favorable properties for their transport through biological membranes. In this context, the first part of this work was focused on the design and the synthesis of a novel type of polycationic dendrons based on adamantane, which are able to penetrate into cells without triggering cytotoxic effects. The next study of this Thesis concerned the investigation of our polycationic adamantane-based dendrons for gene delivery. We evaluated the capacity of the dendrons to complex a plasmid DNA. Hydrophobic compounds (biotin and cholesterol) were covalently bound to the focal point of the dendrons via “click” chemistry and the effects of the dendron generation, the peripheral cationic groups, and the hydrophobic modifications on the formation and stability of the complexes were studied. Finally, the dendrons constituted of an adamantane core, a focal point and three arms, were synthetized starting from a multifunctional adamantane derivative. We have coupled P140, a therapeutic peptide with protective properties in systemic lupus erythematosus, to an adamantane-based dendron and we have analyzed the biological effects of the resulting trimer compared to the monomer

Abstract:
A series of tri-substituted iron and cobalt complexes of the form [M(A)3]n+ were synthesized, and were characterised by UV/Visible absorption and 1H-NMR spectroscopy. The complexes [Co(phen)2(en)]3+ and [Co(bipy)2(en)]3+ have been reported in the literature but 1H-NMR spectroscopy showed that the material produced in both syntheses is [Co(en)3]3+. Spectroscopy further showed that these species cannot be prepared by the literature methods. The complexes were tested in the oxidation of adamantane in the solvents, acetic acid and trifluoroacetic acid and they all oxidised adamantane to a mixture of 1-adamantanol, 1-adamantanol and 2-adamantanone both in the presence and the absence of the oxidant, O2. In all the reactions, however, the yield of conversion was very low. The mechanism for this oxidation was different depending on the presence or absence of O2. In the presence of O2 a catalytic cycle was produced for the oxidation of adamantine. In the oxidation in the presence and absence of O2 there was little variation in activity between the tri-substituted iron and cobalt complexes of 1,10-phenanthroline when compared with the analgous 2,2’-bipyridine complexes. However, the substitution of an ethylenediamine ligand into the co-ordination sphere of cobalt produced significant increase in the activity, although the change was not constant.

Abstract:
>Magister Scientiae - MSc
The pathology of neurodegenerative disorders involves multiple steps, and it is probably for this reason that targeting one particular step in a multi-step process has only yielded limited results. Nitric oxide (NO) is synthesised from L-Arginine by an enzyme known as nitric oxide synthase (NOS). Three isoforms of NOS exist, including endothelial NOS (eNOS), neuronal NOS (nNOS), and inducible NOS (iNOS). In the central nervous system (CNS), nNOS is involved in the synthesis of NO, which is involved in various neurological functions. NO is a free radical and this probably explains why an excess amount of it has been implicated in the development of neurodegenerative disorders. In the CNS, the Nmethyl- D-aspartate (NMDA) receptor in its active state allows the influx of calcium ions which activate nNOS thus increasing the amount of NO and other detrimental reactive nitrogen species within neuronal cells. Calcium entry through voltage-gated calcium channels (VGCC) may also contribute to this. Although calcium ions are important for physiological functioning, an excess is responsible for excitotoxicity, which can ultimately lead to neurodegeneration. Our aim was to synthesise a series of adamantane-derived compounds that act at multiple target sites in the neurodegenerative pathway. By conjugating benzyl and phenylethyl moieties with different functional groups (-H, -NO2, -NH2, -NHC(NH)NH2, -OCH3) to the amantadine structure, we aimed to synthesise compounds that display calcium channel and NMDA receptor (NMDAR) channel inhibition, as well as selective inhibition of nNOS. A series of compounds (-H, -NO2, -NH2, -OCH3) were obtained in yields that varied between 16.5 % and 90.25 %. These novel compounds were tested for calcium influx through VGCC and NMDAR inhibition using synaptoneurosomes isolated from rat brain homogenate against the reference compounds MK-801, NGP1-01, amantadine, memantine and nimodipine. A lack of success with the synthesis of the guanidine compounds prevented the use of the oxyhemoglobin capture assay for the determination of nNOS inhibitory activity of these compounds. The novel synthesised compounds display inhibitory activity towards VGCC and the NMDAR in the micromolar range. Further tests are recommended on compounds SE-1, SE-4, SE-11 and SE-12 as they displayed good inhibitory activity against both NMDAR- as well as ii KCl-mediated calcium influx. These novel compounds may be better therapeutic options than amantadine and memantine as they inhibit both NMDAR and VGCC-mediated calcium influx, whereas amantadine and memantine only inhibit NMDA-mediated calcium influx. These novel adamantane derived compounds may possibly serve as novel leads or potential therapeutic agents for the treatment of neurodegenerative disorders.

Abstract:
This Master’s thesis deals with the problematics of radically initiated compounding of polyethylene by 1-vinyladamantane. Theoretical part focuses on the theory of grafting processes and how they are influenced by chosen process parameters, as well as the properties of used monomer. In experimental part, two sets of experiments were designed, in both cases the chemicals used were polyethylene LITEN MB 87, (2,5-dimethyl-2,5-bis(tert-butylperoxy) hexane), also called Trigonox 101, as the initiator, and chemicals called Ionol and Irgafos 168 as stabilizers. The experiments were carried out in a Brabender batch mixer, the temperature was 180 – 185 °C, the reaction time was 5 minutes. The analytic methods used to evaluate the prepared samples’ properties were the tensile testing, the Charpy notch test, measuring of the melt flow index, analyzing the torque during kneading and the analysis of infrared spectra of the samples. By carrying out of these experiments it was found that excessive crosslinking was present with mass fraction of initiator being as low as 2 %. It was also concluded that under these conditions the modification does not improve tensile properties of the material, but it does improve the impact strength, albeit slightly. The influence of the modification on flow properties needs to be investigated further. A presence of vinyl groups was observed in infrared spectra, suggesting the presence of ungrafted vinyladamantane.

Abstract:
L’adamantane est un hydrocarbure polycyclique, rigide et assez encombrant. En médecine, plusieurs dérivés à base d’adamantane ont été développés notamment comme agent antiviraux. Facilement fonctionnalisés, sa conformation 3D permet d’amoindrir les encombrements stériques entre les différents groupements fonctionnels. Nous avons décidé d’utiliser ses propriétés pour concevoir des structures plus complexes, à savoir, des dendrons et des foldamers. Les dendrons sont des polymères synthétiques possédant des propriétés intéressantes. De par leurs tailles, ils sont considérés comme des nanoparticules et possèdent un ciblage passif des cellules cancéreuses. De plus, facilement fonctionnalisés ils peuvent être utilisés comme molécule cargo dans la vectorisation de principes actifs. Outre la vectorisation, les dendrons permettent d’améliorer les propriétés physico-chimiques d’un médicament (absorption, distribution, métabolisme, élimination et toxicité). Nous avons alors choisi de concevoir des dendrons à base d’adamantane. Ces derniers ont la particularité de ne pas posséder d’espaceur entre les molécules d'adamantane se qui les rend hautement rigides. L’analyse par microscopie électronique à transmission de différents dendrons a permis d’étudier leurs morphologies selon leurs fonctionnalisations ainsi que l’effet du solvant, de la concentration et du support sur leurs auto-assemblages. Dans un second temps, nous avons conçu un acide aminé basé sur l’adamantane. Cet acide g-aminé a ensuite été incorporé dans des séquences peptidiques et les effets de l’adamantane sur la structure secondaire des peptides ont été étudiés par dichroïsme circulaire
Adamantane is a polycyclic hydrocarbon, rigid and quite bulky. In medicine, several adamantane-based derivatives have been developed especially as antiviral agents. Easily functionalized, its 3D well-defined structure considerably decrease the sterical hindrance between its different functional groups. In this context, we decided to use adamantane to build more complex structures such as dendrons and foldamers. Dendrons are synthetic polymers with interesting properties. Because of their size, they are considered as nanoparticles and possess a passive cancer cell targeting. In addition,they are easily functionalized and can be use as vector of drugs. Indeed, the dendrons improve the physochemical properties of a drug (absorption, distribution, metabolism, elimination and toxicity). We decided to combine adamantane and dendrons to build adamantane-based dendrons. However, these dendrons have the particularity of not having spacer between the adamantane moieties, thus, they are highly rigid. Transmission electron microscopy analysis of the different functionalized dendrons allowed to study their self-assembly capacity and their morphology according to their functional groups,the solvent, the concentration and the support. In a second step, we designed an amino acid based on adamantane. This g-amino acid has been introduced in a peptide backbone using solid phase peptide synthesis. Then, the effects of adamantane onto peptide secondary structures have been studied by circular dichroism

Abstract:
Данная статья посвящена производным адамантана, которые уже нашли широкое практическое применение в качестве лекарственных препаратов, обладающих противовирусной активностью, а также средств против болезни Паркинсона. Введение фрагмента адамантана в органические соединения модифицирует их биологическую активность и создаёт благоприятные условия для транспорта органической молекулы через биологические мембраны. This article focuses on adamantane derivatives, which have already found wide practical use as drugs with antiviral activity, as well as agents against Parkinson's disease. The introduction of an adamantan fragment into organic compounds modifies their biological activity and creates favorable conditions for the transport of the organic molecule through biological membranes.
