Patent number: 6942966Abstract: Novel macrocyclic compounds are constructed to include large cyclic structures that are interrupted by at least one ring system. Each interrupting ring system includes two bridgehead atoms. Bridgehead atoms are bonded to one or more bridges that interconnect one or more ring systems thereby forming a large cyclic structure.

Patent number: 6911427Abstract: S-nitrosohemoglobin (SNO-Hb) can be formed by reaction of Hb with S-nitrosothiol and by other methods described herein which do not result in oxidation of the heme Fe. Other methods can be used which are not specific only for thiol groups, but which nitrosate Hb more extensively, and may produce polynitrosated metHb as a product or intermediate product of the method. SNO-Hb in its various forms and combinations thereof (oxy, deoxy, met; specifically S-nitrosylated, or nitrosated or nitrated to various extents) can be administered to an animal or human where it is desired to oxygenate, to scavenge free radicals, or to release NO+ groups to tissues. Thiols and/or NO donating agents can also be administered to enhance the transfer of NO+ groups. Examples of conditions to be treated by SNO-Hbs or other nitrosated or nitrated forms of Hb include ischemic injury, hypertension, angina, reperfusion injury and inflammation, and disorders characterized by thrombosis.Type: GrantFiled: June 12, 1997Date of Patent: June 28, 2005Assignee: Duke UniversityInventor: Jonathan S.

Patent number: 6908737Abstract: A method for multiplexed detection and quantification of analytes by reacting them with probe molecules attached to specific and identifiable carriers. These carriers can be of different size, shape, color, and composition. Different probe molecules are attached to different types of carriers prior to analysis. After the reaction takes place, the carriers can be automatically analyzed. This invention obviates cumbersome instruments used for the deposition of probe molecules in geometrically defined arrays. In the present invention, the analytes are identified by their association with the defined carrier, and not (or not only) by their position. Moreover, the use of carriers provides a more homogenous and reproducible representation for probe molecules and reaction products than two-dimensional imprinted arrays or DNA chips.Type: GrantFiled: April 9, 2002Date of Patent: June 21, 2005Assignee: Vitra Bioscience, Inc.Inventors: Ilya Ravkin, Simon Goldbard, William C.

Patent number: 6881540Abstract: An effective technique for the high throughput screening of displacers is described. In this technique, potential displacers are employed to displace a biomolecule (e.g., protein) adsorbed on a chromatographic resin in small-scale batch displacement experiments. The amount of protein displaced from a specific resin by a defined concentration of displacer is determined by monitoring the supermatant for the protein. By evaluating the displaced protein rather than the displacer itself, this technique enables a single detection technique (e.g., absorbance, fluorescence, etc.) to be employed for all batch displacement experiments. By monitoring the amount of protein displaced, the effacy of a large number of potential displacers can be rapidly evaluated. The entire experimental procedure can be carried out rapidly and is thus amenable to high throughput parallel screening of molecules possessing a large range of affinities and physico-chemical properties.Type: GrantFiled: February 23, 2001Date of Patent: April 19, 2005Assignee: Rensselaer Polytechnic InstituteInventors: Steven Cramer, Kaushal Rege, Jonathan Dordick
