标 题:Devices and methods for the synthesis of nucleic acids
发明人：NGO NAM; JAQUINOD LAURENT; WANG HONG
权利人:CHEMISTRY & TECHNOLOGY FOR GEN
摘要:Cylindrical devices (frits) are prepared by embedding aminoalkyl- or mercaptoalkyl-modified Controlled Pore Glass (CPG) in high-density polyethylene. Methods and devices pertaining to their use in the synthesis of nucleic acids are described. A reusable synthesis column or a reusable 96-chamber synthesis plate have been designed to hold one to 96 of the said frits that are inserted reproducibly into the synthesis chambers with a frit insertor. A short gas surpressure is required to drive entry of chemical reagents into the said frit. Reagents are retained into the frit until a second, longer surpressure is applied to drain the said reagents.

摘要:Type-specific synthesis of bio-polymers of a defined sequence on pre-determined ranges of a solid carrier comprises gradual coupling of monomer and/or oligomer components (I); where, before the coupling step, at least a pre-determined area of the carrier are activated for coupling of (I) to activate the reactive groups; and the temporary group for protection are removed by addition of an activation reagent in aqueous solution, is new. Independent claims are also included for: (1) a procedure for the type-specific synthesis of biopolymers of a defined sequence on pre-determined ranges of solid carrier, comprising: (a) arranging a mask on the carrier (for coupling of (I) of the biopolymer, which is to be synthesized for controlling available reactive groups with protection groups to the carrier); (b) activating the reactive groups by removing the temporary protective groups at the ranges given by the mask, by adding the activation reagent in aqueous solution; (c) coupling (I) with activated reactive groups; and (d) repeating step (a) to (c), until the desired biopolymers is synthesized; (2) a micro array prepared by the process; and (3) a micro array with pre-determined ranges immobilized biopolymer probes, where the proportional portion P at biopolymers, which exhibits the desired number of monomer M, is given by the formula P = S-M (where S is an average step yield with the coupling of (I); and the density at pre-determined ranges is at least 1500 spots per cm 2>and the average step yield is 95 (preferably 98) %).

标 题:Synthesis of rocaglamide natural products via photochemical generation of oxidopyrylium species

权利人:UNIV BOSTON
摘要:The present invention provides new strategies for the synthesis of compounds of the rocaglamide family and related natural products. In particular, the new biomimetic synthetic approach involves photochemical generation of an oxidopyrylium species from a 3-hydroxychromone derivative followed by 1,3-dipolar cycloaddition of the oxidopyrylium species to a dipolarophile. This approach can be used for the formation of adducts containing an aglain core structure. Methods for the conversion of aglain core structures to aglain, rocaglamide and forbaglin ring systems are also provided. The present invention also relates to the use of rocaglamide/aglain/forbaglin derivatives for the manufacture of medicaments for use in the treatment of cancer or cancerous conditions, disorders associated with cellular hyperproliferation, or NF-κB-dependent conditions.
