Details for Patent: 5,723,592

Title: Parallel selex
Abstract:This invention discloses a method for coevolving products from two or more reactants, along with the nucleic acid that can facilitate the reaction for making the products. The invention further discloses the products and facilitating nucleic acids produced by said method.
Inventor(s): Eaton; Bruce E. (Boulder, CO), Gold; Larry (Boulder, CO)
Assignee: NeXstar Pharmaceuticals, Inc. (Boulder, CO)
Filing Date:Jun 05, 1995
Application Number:08/462,389
Claims:1. A non-naturally occurring facilitating nucleic acid that facilitates a bond formation reaction between a first reactant and a free reactant, wherein said bond formation reaction is selected from the group consisting of a condensation reaction, a hydrolysis reaction, a cycloaddition reaction, a conjugate addition reaction, an aldol condensation reaction, a cyclopropanation reaction, a hydrogenation reaction, and a cyclotrimerization reaction, wherein each reactant is comprised of a small organic molecule with a molecular weight in the range of 2 to 1000, and further wherein said first reactant is coupled to said nucleic acid.

2. A non-naturally occurring facilitating nucleic acid which increases the reaction rate of a bond formation reaction to form a product from a first reactant and a free reactant, wherein said bond formation reaction is selected from the group consisting of a condensation reaction, a hydrolysis reaction, a cycloaddition reaction, a conjugate addition reaction an aldol condensation reaction, a cyclopropanation reaction, a hydrogenation reaction, and a cyclotrimerization reaction, wherein each reactant is comprised of a small organic molecule with a molecular weight in the range of 2 to 1000, and further wherein said first reactant is coupled to said nucleic acid.

3. The facilitating nucleic acid of claim 1 wherein the nucleic acid is selected from the group consisting of single-stranded RNA, single-stranded DNA, and double-stranded DNA.

4. The non-naturally nucleic acid of claim 1 wherein the nucleic acid is selected from the group consisting of single-stranded RNA, single-stranded DNA, and double-stranded DNA.
