Full textO câncer é uma das doenças mais temidas pela sociedade, sendo uma das principais causas de morte em todo o mundo. Desta maneira, estudos contínuos buscando compreender seus mecanismos de evolução são imprescindíveis para que se possa erradica-lo do organismo. Embora a quimioterapia seja amplamente empregada em praticamente todos os casos de câncer, a resistência a múltiplas drogas tende a diminuir a eficiência deste tratamento. Para contornar esta problemática, o conceito de hibridação molecular vem sendo explorado entre os químicos orgânicos sintéticos, a fim obter fármacos variados que explorem diferentes mecanismos de ação. Nas últimas décadas, a descoberta de vias de sinalização superexpressas em células cancerosas permitiu uma nova abordagem na terapêutica com efeitos colaterais diminuídos nos pacientes e eficiência elevada. Dentre elas, as enzimas PI3K e AMPK merecem destaque por constituírem vias de sinalização que desencadeiam uma grande quantidade de outras enzimas envolvidas no progresso do câncer, como Akt, mTOR e ERK 1/2. Neste contexto, o presente trabalho está baseado na síntese e estudo de ancoragem molecular utilizando as enzimas PI3K e AMPK como proteínas- alvo de híbridos contendo os núcleos naftoquinonas, quinolinas e triazinas - com reconhecida atividade antitumoral. Os resultados de ancoragem mostraram que a maioria dos híbridos propostos possui energia de interação receptor/ligante superiores aos fármacos controle para suas respectivas enzimas, sugerindo a inibição dessas vias de sinalização como possível forma de ataque ao câncer. Além disso, a natureza das interações e os resíduos de aminoácidos envolvidos na formação do complexo receptor/ligante são semelhantes para os fármacos controle e os candidatos propostos, corroborando com a assertiva feita acerca do mecanismo de ação baseada na análise da magnitude da energia de interação. Resultados satisfatórios também foram alcançados na síntese dos candidatos a fármaco: um híbrido quinolínico-naftoquinônico 120, um triazino- naftoquinônico 125 (ambos inéditos) e um triazino-quinolínico 127 foram sintetizados.

Full textThis work focused on the synthesis and applications of a novel series of heteroaromaticcompounds: the 4H-pyrido[e][1,3]oxazin-4-ones. The first part of this thesis presents thepreparation of these pyrido-oxazinones via an intramolecular O-arylation reaction. The secondpart of this work relies on the reactivity of these chemical entities and their use as buildingblocks. The functionalization of the 4H-pyrido[e][1,3]oxazin-4-ones has been studied viacross-coupling reactions to obtain more elaborated structures. The pyrido-oxazinones werealso converted, in one step, into other diverse small molecules of interest: 1,3,5-triazines,1,2,4-triazoles and 1,2,4-oxadiazoles. The last part of this thesis was devoted to the use of theobtained heterocycles as potential fluorescent probes for the detection of carbonylatedproteins

Here we report that the self-assembly of serveral metal ions and ligands leads to the formation of a series of metal-organic frameworks (MOFs). Different MOFs were obtained with the choice of the entitled ligands. 4, 4’, 4’’-s-triazine-2, 4, 6-triyltribenzoic acid (p-TATB) results in {[In(p-TATB)(H2O)(DMSO)]•2DMSO}n (1); 3, 3’, 3’’-s-triazine-2, 4, 6-triyltribenzoic acid (m-TATB) results in {[Zn2(m-TATB) (H2O)2]•0.5(C2O4)•DMA}n (2) and {(H2NEt2)[In(m-TATB)Cl]•1.5DEF•H2O}n (3); 4-sulfobenzoic acid (4-SBA) results in {K2[Ln2(4-SBA)4(H2O)4]}n (Ln = Eu(4a), Gd(4b), Tb(4c), Dy(4d), Ho(4e), Y(4f), Eu+Tb(4g)). Single-crystal X-ray diffraction studies indicate 1 has four identical interwoven 3D nets with solvent-accessible volume of 46.9% calculated using PLATON, but when its solvent molecules are removed, 1 transforms to amorphous phase. 2 has two-fold interwoven 3D nets with solvent-accessible volume of 34.4%. After solvent exchange, 2 transforms to amorphous phase. Nevertheless, when 2 soaks in origin solvent, 2 transforms to another new phase. 3 also has two-fold interwoven 3D nets with solvent-accessible volume of 51.4%. Removing guest solvent molecules, the framework of 3 remains intact. 4a-4g are isostructures adopting 2D frameworks. Complexes 4a(Eu), 4c(Tb), 4d(Dy), 4e(Ho) and 4g(Eu+Tb) exhibit photoluminescent properties, giving characteristic Ln3+ emissions.

Here we report the synthesis and characterization of a series of metal-organic frameworks (MOFs), resulted from the self-assembly of metal ions and entitled ligands, 4,4’,4”-s-triazine-2,4,6-triyltribenzoate (pTATB) and 2,2’,2”-s-triazine-1,3,5-triyl-tri-o-aminobenzoate (oTATAB) : [(CH3)2NH2]3[Ga3(pTATB)4]•22DMF•7H2O (1), [Cu3(oTATAB)2(H2O)3]•10DMA•3H2O (2) and [Ln4Na2(oTATAB)4(DMA)12](NO3)X (Ln= La(3a), Ce(3b), Nd(3c); X=Cl、Ln=La(3d); X=I). Single-crystal X-ray diffraction studies indicate 1 has two identical interwoven 3D networks with solvent-accessible volume of 70.3% calculated using PLATON. Compound 2 crystallizes in cubic space group Pa-3. In its structure, two copper atoms are bridged by four carboxylates to form the well-known paddlewheel secondary building unit with axial aqua ligands. The framework of 2 remains intact after solvent-exchange by THF and ACN. Reversible crystal to amorphous transformation has also been observed in 2. In addition, we also synthesized four 3D isostructures, [Ln4Na2(oTATAB)4(DMA)12](NO3)X (Ln= La(3a), Ce(3b), Nd(3c); X=Cl、Ln=La(3d); X=I). The solvent accessible free volumes of (3a) to (3d), calculated by PLATON, are approximately 51% of the crystal volume. The structure of (3a) to (3d), appear to collapse into amorphous phases upon the removal of solvent molecules were studied by thermal analyses and powder X-ray diffraction. This structure is similar to {[Ln2(pTATAB)2(H2O)(DMA)3]•xH2O}n and {[Ln2(mTATAB)(DMA)3]}n, but its structure has to add the sodium ions . And the sodium atom and six carboxylates of the framework have interaction to stabilize two identical interwoven 3D networks.

Here we report that the self-assembly of serveral metal ions and ligands leads to the formation of a series of metal-organic materials (MOMs). The choice of tetrazolate-based ligand, 2,3-di-1H-tetrazol-5-ylpyrazine (H2dtp) results in (NH2Me2)[CuIdtp] (1) and (NH2Me2)4[Mdtp2Cl2] ( M = Cu2+ (2), Mn2+ (3) ), while 4′,4′′-s-triazine-1,3,5-triyltri-p-aminobenzoic acid (H3TATAB) affords (Me2NH2)3[In(TATAB)2].2DMF (4), (NH2Me2)3[In3(TATAB)4].3DMF.20H2O (5) and [Cu3(TATAB)2(H2O)3] (6). Single-crystal X-ray diffraction studies indicate 1 has a 2D structure, 2 and 3 are discrete molecules, 4 is one-dimensional, 5 and 6 are 3D networks, of which two-fold interpenetration is observed in 6. Porosity calculations for 5 and 6 based on PLATON, suggest 61.4% and 66.2% void space for 5 and 6, respectively. Thermal stability of compounds 1, 5 and 6 were studied by thermal analyses and powder X-ray diffraction. As a result, 1 is thermally stable up to 340℃, whereas the structures of 5 and 6, appear to collapse into amorphous phases upon the removal of solvent molecules. The luminescent emissions for all compounds were also measured. Bands due to intra-ligand transitions were observed. In addition, compounds 1, 2, and 3 also exhibit new bands, which can be attributed to metal-to-ligand charge transfer (MLCT).

Here we report that the self-assembly of lanthanide ions with functional organic ligands, such as carboxylate group and sulfonate group.We have synthesized fourteen novel metal-organic materials, as following: {[Sm(2STP)(H2O)3](H2O)}n (1) {K[Ln(4SBA)2(H2O)]}n { Ln = Sm (2), Eu (3), Tb (4), Nd(5)} [Ln(mTATAB)(DMA)3]n { Ln = La (6), Ce (7), Pr (8), Nd (9), Sm (10), Eu (11), Gd (12), Tb (13), Dy (14)} ( 2STP = 2-sulfoterephthalate; 4SBA = 4-sulfobenzoic acid; mTATAB = 3,3’,3’’-s-Triazine-1,3,5-triyltri-m-aminobenzoate) In this thesis, their syntheses, structural characterization, thermal properties, and luminescence properties, are discussed. Compounds 1 is a 2-D framework: The metal-oxide 1-D chain and 2STP constructed a 2-D network, and the 2-D sheet packed to a 3-D structure by hydrogen bonding from coordinated water and sulfonate group. Compounds 2 to 5 are 3-D structures. It constructed a 2-D plane by metal-oxide, then form a 3-D framework with bridging water. Compounds 6 to 14 are 3-D isostructures with 2-fold interpenetration. The coordination number of lanthanum metal is nine, including three mTATABs and three DMAs. The inversion center of two centrosymmetric domains is located at (a/2, b/2, c/2) of unit cell. The solvent-accessible free volumes of Ln(mTATAB)(DMA)3 calculated by PLATON, are approximately 45% of the crystal volume, which are potentially porous materials. Compounds 1(Sm), 2(Sm), 3(Eu), 4(Tb), 10(Sm), 11(Eu), 13(Tb), 14(Dy) have luminescence properties in UV-vis range, which can contribute to characteristic lanthanide emissions. For compounds containing terbium or europium, which exhibit intence emissions, in other words, they have better energy transfer efficiency in antenna effect.
