The present invention relates to compounds of formula I:or a pharmaceutically acceptable salt or mixtures thereof that inhibit serine protease activity, particularly the activity of hepatitis C virus NS3–NS4A protease. As such, they act by interfering with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The invention further relates to compositions comprising these compounds either for ex vivo use or for administration to a patient suffering from HCV infection and to processes for preparing the compounds. The invention also relates to methods of treating an HCV infection in a patient by administering a composition comprising a compound of this invention. The invention further relates to processes for preparing these compounds.

The present invention discloses novel peptide compounds which have HCV protease inhibitory activity as well as methods for preparing such compounds. In another embodiment, the invention discloses pharmaceutical compositions comprising such compounds as well as methods of using them to treat disorders associated with the HCV protease.

A composition comprising an amphoteric or pseudo-amphoteric agent and a polyhydroxy alpha hydroxyacid existing as a free acid, lactone, or salt, and isomeric or non-isomeric forms thereof is provided. The amphoteric or pseudo-amphoteric agent can be selected from amino acids, dipeptides, aminoaldonic acid, aminouronic acid, lauryl aminoproplyglycine, aminoaldaric acid, neuraminic acid desulfated heparin, deacetylated hyaluronic acid, hyalobiuronic acid, chondrosine, deacetylated chondroitin, creatine, creatinine, hydroxyproline, homocysteine, homocystine, homoserine, ornithine, citrulline, phosphatidylserine, and sphingomyelin. The composition may contain other additives, including cosmetic or pharmaceutical agents for topical treatment of dermatological disorders.

The present invention provides a method for obtaining site-specific recombination in a eukaryotic cell, the method comprising providing a eukaryotic cell that comprises a first recombination attachment site and a second recombination attachment site; contacting the first and second recombination attachment sites with a prokaryotic recombinase polypeptide, resulting in recombination between the recombination attachment sites, wherein the recombinase polypeptide can mediate recombination between the first and second recombination attachment sites, the first recombination attachment site is a phage genomic recombination attachment site (attP) or a bacterial genomic recombination attachment site (attB), the second recombination site is attB or attP, and the recombinase is selected from the group consisting of a Listeria monocytogenes phage recombinase, a Streptococcus pyogenes phage recombinase, a Bacillus subtilis phage recombinase, a Mycobacterium tuberculosis phage recombinase and a Mycobacterium smegmatis phage recombinase, provided that when the first recombination attachment site is attB, the second recombination attachment site is attP and when the first recombination attachment site is attP, the second recombination attachment site is attB. The invention also describes compositions, vectors, and methods of use thereof, for the generation of transgenic cells, tissues, plants, and animals. The compositions, vectors and methods of the present invention are also useful in gene therapy applications.

The present invention discloses novel compounds which have HCV protease inhibitory activity as well as methods for preparing such compounds. In another embodiment, the invention discloses pharmaceutical compositions comprising such compounds as well as methods of using them to treat disorders associated with the HCV protease.

The present invention is directed to novel 3-benzoimidazolyl-pyrazolopyridine compounds of formula (I):and pharmaceutically acceptable forms thereof and their synthesis and use as inhibitors of serine-threonine protein kinases and tyrosine protein kinases and interactions thereof.

Antibodies immunoreactive to double mutant EPSPS are provided, and in an embodiment the double mutant EPSPS is one in which the wild-type EPSPS is substituted at residue 102 with isoleucine and at residue 106 with serine. Also provided are hybridomas producing the antibodies, as well as methods of making and using the antibodies.
