摘要:Methods for the preparation of inorganic nanoparticles capable of fluorescence, wherein the nanoparticles consist of a host material that comprises at least one dopant. The synthesis of the invention in organic solvents allows to gain a considerably higher yield compared to the prior art synthesis in water. All kinds of objects can advantageously be marked and reliably authenticated by using an automated method on the basis of a characteristic emission. Further, the size distribution of the prepared nanoparticles is nartower which renders a subsequent size-selected separation process superfluous.

摘要:The 2-(4-tolylsulfonyl)ethoxymethyl (TEM) as a new 2'-OH protecting group is reported for the RNA synthesis on the solid support using the phosphoramidite chemistry. The usefulness of the 2'-0-TEM group is exemplified by the synthesis of 12 different oligo-RNAs of various sizes (14-38nt long). The stepwise coupling yield varied from 97 - 99 % with an optimized coupling time of 120s. Synthesis of all four pure phosphoramidite building blocks are also described. Two new reliable parameters, δc2' - δc3s and δn2' - δH3' have been suggested for the characterization of isomeric 2'-0-TEM and 3'-0-TEM as well as other isomeric mono 273 '-protected ribonucleoside derivatives. The most striking feature of this strategy is that the crude RNA prepared using our 2'-0-TEM strategy is sufficiently pure (>90 %) for molecular biology research without any additional purification step, thereby making oligo-RNAs easily available at a relatively low cost, saving both time and lab resources.

标 题:Synthesis of sodium narcistatin and related compounds
发明人：PETTIT GEORGE R; MELODY NOELEEN

摘要:The present invention involves use of the compounds narciclasine (2a) and 7-deoxy-narciclasine (2c), which are obtained via isolation from the medicinal plant species Narcissus (Amaryllidaceae), as precursors in a novel synthesis method in which each of these compounds are selectively hydrogenated to produce trans-dihydronarciclasine (1a) and 7-deoxy-trans-dihydronarciclasine (1c). Also described herein is a novel synthesis method for producing sodium narcistatin (11) from narciclasine (2a). Further described herein are certain novel 3,4-cyclic phosphate prodrugs, including sodium-7-deoxynarcistatin (8), sodium-7-deoxy-transdihydronarcistatin (9), and sodium transdihydronarcistatin (10).
