The government has certain rights in the invention.
摘要:
An analog-ligand having a conformation that substantially corresponds to the conformation of a hydrolytic transition state of an amide or ester reactant ligand is used to produce receptor molecules of predetermined specificity. The receptor molecules include an antibody combining site that binds to the analog-ligand and also to a reactant ligand and thereby stabilizes the tetrahedral carbon atom of the amide or ester hydrolysis transition state of that reactant ligand to catalytically hydrolyze the reactant ligand at a predetermined site.

The present invention describes an encoded combinatorial chemical library comprised of a plurality of bifunctional molecules having both a chemical polymer and an identifier oligonucleotide sequence that defines the structure of the chemical polymer. Also described are the bifunctional molecules of the library, and methods of using the library to identify chemical structures within the library that bind to biologically active molecules in preselected binding interactions.

A method for treating or preventing a host mammal that exhibits aversive signs and symptoms present during protracted abstinence or extended discontinuation syndromes as seen after cessation of compulsive activity, behaviors, or substance use is disclosed. That method comprises administering to a host mammal in need a pharmaceutical composition containing an aversive sign and symptom lessening amount a compound of Formula I or a pharmaceutically acceptable salt thereof dissolved or dispersed in a physiologically acceptable diluent, and repeating the administration as needed, wherein W, X, Y and Z, R1 and Ar are defined within. Data are provided in rats as host mammals using behavioral models dependent on the CRF1 system: defensive burying, alcohol dependence, cocaine dependence and nicotine dependence. A contemplated method also is useful for inhibiting relapse of such a behavior. A contemplated method also is useful for treating substance-related or substance-induced psychiatric disorders that include aversive signs and symptoms.
摘要:
An antibody molecule or molecule containing antibody combining site portions (catalytic molecule) that catalytically hydrolyzes a preselected carboxylic acid amide or ester bond of a reactant ligand, methods of making and using the catalytic molecule, and cells that produce those molecules are disclosed. The catalytic molecules bind to a reactant ligand containing the bond to be hydrolyzed and also to a haptenic ligand. The haptenic ligand is structurally analogous to the reactant ligand and contains a tetrahedral carbon atom that is bonded to a hydroxyl group and to a saturated carbon atom at a position in the haptenic ligand that corresponds to position of the carbonyl group and its bonded heteroatom of the reactant ligand. The haptenic ligand also contains a group that bears an ionic charge in aqueous solution at physiological pH values that is not present at a corresponding position of the reactant ligand. The ionic charge-bearing group is located in the hapten within 7 .ANG.ngstroms of the tetrahedral carbon atom.

摘要:
The present invention contemplates monoclonal antibody combining site-containing molecules that catalyze the formation of a 6-membered ring compound from a 5,6-ethylenically-unsaturated-1-sulfonate substrate. The catalytic molecules bind to the substrate molecule as well as to a structural analog of the substrate that is a piperidine N-oxide whose nitrogen atom is in the same relative position in that ring as the sulfonate-bearing carbon atom of the open-chain substrate. A hybridoma that secretes the catalytic molecules and a process for forming a 6-membered ring compound that utilizes the catalytic molecules are also disclosed.
