摘要:
The present invention discloses compounds of formula (I), or pharmaceutically acceptable salts, esters, or prodrugs thereof: which inhibit RNA-containing virus, particularly the hepatitis C virus (HCV). Consequently, the compounds of the present invention interfere with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a subject by administering a pharmaceutical composition comprising the compounds of the present invention. The present invention relates to novel antiviral compounds represented herein above, pharmaceutical compositions comprising such compounds, and methods for the treatment or prophylaxis of viral (particularly HCV) infection in a subject in need of such therapy with said compounds.

Nucleic acids encoding recombinant CD4-fusion proteins are disclosed herein that include a CD4 polypeptide ligated at its C-terminus with a portion of an immunoglobulin comprising a hinge region and a constant domain of a mammalian immunoglobulin heavy chain. The portion of the IgG is fused at its C-terminus with a polypeptide comprising a tailpiece from the C terminus of the heavy chain of an IgA antibody or a tailpiece from a C terminus of the heavy chain of an IgM antibody. Also disclosed herein are methods for using these CD4-fusion proteins.
摘要:
Methods and devices are provided for reducing the concentration of low molecular weight compounds in a biological composition containing cells while substantially maintaining a desired biological activity of the biological composition. The device comprises highly porous adsorbent particles, and the adsorbent particles are immobilized by an inert matrix. The matrix containing the particles is contained in a housing, and the particles range in diameter from about 100 μm to about 1500 μm. The device can be used to adsorb and remove a pathogen-inactivating compounds from a biological composition such as a blood product.
摘要:
A novel and stable attenuated poliovirus, which replicates in neuroblastoma cells, is produced by engineering an indigenous replication element (cre), into the 5′ non-translated genomic region and inactivating the native cre element located in the coding region of 2C (mono-crePV). The stably attenuated poliovirus replicates in a neuroblastoma model (Neuro-2aCD155 tumors) expressing CD155, the poliovirus receptor, and is effective for oncolytic treatment and cure of solid tumors, such as neuroblastoma.
摘要:
The present invention discloses compounds of formula I or pharmaceutically acceptable salts, esters, or prodrugs thereof: which inhibit serine protease activity, particularly the activity of hepatitis C virus (HCV) NS3-NS4A protease. Consequently, the compounds of the present invention interfere with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a subject by administering a pharmaceutical composition comprising the compounds of the present invention.
摘要:
The present invention is directed to compounds of formula (I), and pharmaceutically acceptable salts and solvates thereof, their synthesis, and their use as modulators or inhibitors of the human immunodeficiency virus “HIV” integrase enzyme. Formula (I).
摘要:
The present invention is directed to a method for producing commercial quantities of baculovirus using a combination of methods involving producing occlusion bodies with infectious baculovirus in caterpillar larvae and large numbers of viral particles with serial passages in cell culture. A two step method was developed by initially producing infectious virus in caterpillar larvae and then using the resultant infectious virus as an inoculum for a limited number of serial passages in cell culture so to produce large amounts of infectious baculovirus.
摘要:
The present invention relates to novel compounds and compositions having antiviral activity. The invention also relates to methods for the therapeutic or prophylactic treatment of viral infections in mammals.
摘要:
Provided herein are macrocyclic serine protease inhibitor compounds, for example, of Formula I, pharmaceutical compositions comprising such compounds, and processes of preparation thereof. Also provided are methods of their use for the treatment of an HCV infection in a host in need thereof.
摘要:
The invention provides a composition comprising for simultaneous, sequential or separate administration a) a polyanion; and b) an antibody reactive against an antigen on the surface of an intracellular form of a virus, which virus has an extracellular form that is surrounded by one lipid membrane more than the intracellular form. The present inventors have found that the compositions according to the invention comprising an antibody and a polyanion can neutralize virus infectivity more efficiently than other compositions reported hitherto.
