摘要:
A series of novel oxirane derivatives, which are useful for inhibiting HIV are disclosed. Particularly of value are peptidomimetic compounds, containing a terminal epoxide group on a peptide or psuedopeptide backbone, which are believed to inhibit HIV protease by extruding enzyme-bound water molecules from the active site of the enzyme.

A peptide linkage unit is employed for joining peptide and pseudopeptide sequences, including peptides and pseudopeptides that inhibit aspartic proteinase enzymes. The peptide linkage unit includes a phosphinate methylene ammonium linkage in place of a peptidyl carboxamide bond. If the peptide linkage unit is incorporated into a peptide sequence that would otherwise serve as an aspartic proteinase substrate and if it is positioned at a cleavage site within such peptide sequence, the phosphinate methylene ammonium linkage is resistant to cleavage and serves as an exploding transition state analog of such cleavage site. When so incorporated, the phosphinate methylene ammonium linkage can bind or interfere with the active site of aspartic proteinase enzymes and inhibit its activity. Preferred inhibitors contain a phosphinic acid methylene amine group joining the P.sub.1 and P.sub.1 ' residues and have a length of 3 to about 15 amino acid residues.

The invention describes the display of exogenous polypeptides on filamentous phage using a fusion between the exogenous polypeptide and phage pVII or pIX proteins. In particular, phage particles and phagemid vectors are described for expression and display of heterodimeric proteins such as antibody Fv heterodimers in combinatorial libraries, and uses thereof.

The conjugates provided are in certain embodiments, for compositions and methods in treatment of variety of diseases and have the formula 1: D-L-S (1) or formula 2: D-L-S′ (2) wherein D is a drug moiety; L, which may or may not be present, is a non-releasing linker moiety; S is a substrate for a kinase, other than a hexokinase, a protein kinase or a lipid kinase; and S′ is a substrate for a phosphotransferase, other than a hexokinase, a protein kinase or a lipid kinase.
摘要:
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 anti-cocaine vaccine employs a cocaine hapten conjugated to a carrier protein. The anti-cocaine vaccine elicits an immune response which reduces the psychoactive effects of cocaine consumption by the production of anti-cocaine polyclonal antibodies. The antibodies may be employed in an ELISA test for assaying cocaine. The immune response elicited by the anti-cocaine vaccine produces antibody producing cells which may be isolated and cloned for producing anti-cocaine monoclonal antibodies.
