Abstract:
A presente invenção relata a obtenção de compostos carbonílicos e derivados, através de sínteses com alto rendimento e pureza, proporcionando princípios ativos antitumorais com propriedades antiproliferativas seletivas e atividade antimetastática. A presente invenção refere-se ao desenvolvimento de novos butadienos push-pull polifuncionais e seus derivados O e C-prenilados, benzoilados e iodados, com alta conjugação eletrônica na cadeia lateral. Estes compostos exibem alta seletividade antitumoral, provocando a morte celular por apoptose, mostram também propriedades antimetastáticas e não mutagênicas nos estudos experimentais realizados.
Abstract:
This invention discloses aromatic based sulfur containing hydrophobic acrylate monomer with high refractive index. The invention further discloses process for the preparation of 2-phenyl-2-(phenylthio)ethyl acrylate of the formula (I). This monomer can be polymerized to take the form of an optical products having high refractive index. Optical products made from this monomer having high refractive index can be thinner and provide same refractive power as product made from a material having a relatively low refractive index. In particular the polymeric material prepared from the novel monomer can be used for making intraocular lenses that are thinner than the conventionally used ones offering advantages of reduced volume of space and light weight materials.

Abstract:
Novel tridentate-, bidentate-, and monodentate-based aromatic adsorbates including self-assembled monolayers (SAMs), especially, mixed multi-component SAMs, where the adsorbates comprise an aromatic ring including one head group or a plurality of dentate head groups and one tunable tail group or a plurality of tail groups and methods for making the same, and methods for using same, their use in the preparation of homogeneously mixed multi-component self-assembled monolayers (SAMs). The adsorbants and SAMs derived therefrom are ideally suited for biosensing, biosensing diagnostics, biological interfacial mimics, surface protections for nanoparticles, inert coatings for artificial implants, and corrosion-resistant coatings for microelectronics components.
Abstract:
This invention generally relates to nanocrystal compounds, and linker arm for nanocrystal compounds that attach the nanocrystals to the organic compounds. The nanocrystal compound comprises a nanocrystal, linker arm, and organic compound. Preferably, the organic compound is a biologically active compound that can provide a fluorescent sensor. Preferably, the linker arm is a polyether chain with an attachment point for the nanocrystal and an attachment point for the organic compound. Specifically, the nanocrystal is attached to the linker arm through a R group and the organic compound is attached to the linker arm through a R2 group.R is a bond or is selected from the group consisting of: SH, O(CH2(n)O)nSH, NH(CH2(n)O)nSH, NH(CH2(n)NH)SH, S(CH2(n)O)nSH, and S(CH2(n)S)SH. n is 1-10, with S being attached to the nanocrystal. R2 is a bond or selected from the group consisting of carbonyl, NH, S, CONH, COO, S, C1-10 alkyl, carbamate, and thiocarbamate.
