Monoclonal antibodies specific for the m2-1 antigen of respiratory syncytial virus (RSV)

The use of monoclonal antibodies specific for respiratory syncytial virus (RSV). Specifically, to a monoclonal antibody IgG2A secreted by the cell line of 8A4/G9 hybridoma specifically directed to the M2-1 viral antigen, which is associated with the nucleocapside of the virus. The antibodies can be used for assays for the detection and/or determination of RSV infection. The antibodies are in the pure state and do not contain any other contaminating biological material. A method for preventing and treating the infection caused by respiratory syncytial virus (RSV) in a given host is provided, including the administration of a composition containing the monoclonal antibodies secreted by the 8A4/G9 hybridoma in sufficient doses to prevent the disease. The antibody can be humanized in order to minimize the possibility of an immune response against the same in the patient. In addition, it can be used to obtain any pharmaceutical form of the formulation of the monoclonal antibodies secreted by the 8A4/G9 hybridoma, which are suitable for the treatment or prevention of the disease caused by RSV. It also provides methods for detection and diagnosis of RSV viral antigens in biological samples using the monoclonal antibodies produced and secreted by cells of the 8A4/G9 hybridoma.

Compounds for treatment of hepaci virus infection and method for determining therapy of hepaci virus infection, in particular, hcv infection

In a first aspect, the present invention relates to new compounds based on diphenylpiperazine and diphenylpiperidine structures. In particular, the present invention provides new flunarizine derivatives having improved hepaci virus infection inhibitory activity. In a further aspect, the present invention relates to a pharmaceutical composition containing said compound as well as the use of said pharmaceutical composition and the compounds according to the present invention in preventing or treating hepaci virus infection, in particular, HCV virus infection, like HCV of genotype 2. Moreover, a method for determining effectiveness of prophylactic or therapeutic treatment of hepaci virus, like HCV infection as well as a method for determining the therapy regimen of an individual afflicted with hepaci vims infection including HCV infection is provided. Said method is based on determining the sequence or interfacial hydrophobicity of the hepaci virus E1 protein. This may include determining the presence of mutations at predetermined positions of the E1 sequence. Based on determining the interfacial hydrophobicity of the E1 protein, the sensitivity to a diphenylpiperazine or diphenylpiperidine based hepaci virus inhibitor as well as a phenothiazine and cycloheptenepiperidine based hepaci virus inhibitor can be determined. When the central hydrophobicity region is disrupted or the hydrophobicity is below zero applying the Wimley-White hydropathy plot, or the mutations at positions 290, 299, 301 and 310 of SEQ ID No. 1 are present, it is submitted that the sensitivity against said compounds is reduced. Hence, it is possible to determine the therapy regimen of an individual afflicted with hepaci virus infection or being a risk of being afflicted with hepaci vims infection, in particular HCV infection like HCV genotype 2 infection.
