摘要:Disclosed in the present invention are a synthesis method and application of a benzoselenazole-1-ketone compound and a derivative thereof. Sulfoximine and the element selenium are used as raw materials, and by means of a rhodium catalysis direct C-H functionalization reaction, synthesis of a series of benzoselenazole-1-ketone compounds is achieved. The solution has the advantages of strong functional group compatibility, wide substrate universality, mild conditions, simple operations, and high efficiency and universality. Meanwhile, sulfoximine and the element selenium are used as initial raw materials, a direct C-H functionalization reaction is carried out, and by means of chiral phosphoric acid, synthesis of the chiral benzoselenazole-1-ketone compound is achieved. The application prospect is good, and a sulfydryl structure in biomacromolecules such as polypeptides, saccharides, drug molecules and proteins can be specifically marked. Good anti-SARS-CoV-2 virus activity is exhibited, a trastuzumab biological conjugate can effectively image HER 2 receptors on the cell surface, displays strong fluorescence, and can be applied to the preparation of an imaging reagent for the HER 2 receptor on the cell surface.

标题:Design and synthesis of instant - degradable plastics
发明人：ROSEN OREN
摘要:A novel class of instant degradable synthetic polymeric plastics having the characteristics and properties of conventional forms of plastics is developed by providing a new application advantage of incorporating latent, labile, dormant chemical bond nuclei such as disulfide and sulfenyl derivatives of the plastic compounds with latent nucleophilic properties. The special advantage of the instant degradable polymers over the existing biodegradable and other degradable polymer counterparts, is their engineering and design, which makes the kinetics of their degradation instant, and the chemical and physical properties of their by-products allows soluble dissolution into non-toxic aqueous solvent media, thus enabling a practical treatment of waste and avoiding bio-hazardous pollution of the environment. These novel plastic products are made from a variety of compositions of polymers and their compatible nontoxic modifiers. The resulting novel instant degradable plastic products retain latent dormant solubility properties that are triggered upon mild chemical reaction, thus enabling cost effective and facile recycling of plastic refuge.

标题 :Synthesis of Alloyed Nanocrystals in Aqueous or Water-Soluble Solvents

摘要:The present invention relates to nanocrystals and methods for making the same; in particular, the invention relates to ternary or higher alloyed nanocrystals and methods for making such structures in aqueous or water-soluble solvents. In certain embodiments of the invention, methods of preparing ternary or higher alloyed nanocrystals involve providing at least first, second, and third nanocrystal precursors (e.g., NaHSe, ZnCl 2 , and CdCl 2 ) and forming nanocrystal structures in an aqueous or water-soluble solvent. In some cases, nanocrystal precursor solutions may also include a water-soluble ligand (e.g., glutathione, GSH). As such, ternary or higher alloyed nanocrystals (e.g., Zn x Cd)— x Se) comprising the at least first, second, and third nanocrystal precursors may be formed, and the water-soluble ligand may coat at least a portion of the surface of the ternary or higher alloyed nanocrystal. Advantageously, methods for forming nanocrystals described herein can be performed at low temperatures (e.g., less than 100 degrees Celsius), and, in some embodiments, do not require the use of organic solvents. The present inventors have applied these methods to prepare blue-emitting nanocrystals with emissions that are tunable between 400-500 nm, and with quantum yields of greater than 25% in aqueous solution. These nanocrystals may be highly water soluble and can be used in a variety of applications, including those involving cell culture, sensing applications, fluorescence resonance energy transfer, and in light-emitting devices.

权利人:XENOPORT INC
摘要:Disclosed herein are methods for synthesizing 1-(acyloxy)-alkyl prodrug derivatives of drugs through oxidation of 1-acyl-alkyl derivatives of drugs under anhydrous reaction conditions. The methods typically proceed stereospecifically, in high yield, do not require the use of activated intermediates and/or toxic compounds and are readily amenable to scale-up.
