Abstract:
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 virus 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 Wim ley-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 virus infection, in particular HCV infection like HCV genotype 2 infection.
Abstract:
Provided herein are methods, systems, kits, and compositions useful for determining small molecule-protein interactions and protein-protein interactions. The photo-click tags provided herein can be conjugated to a small molecule or amino acid analog to provide compounds that can be integrated into a protein through photo-conjugation, allowing for identification of a small molecule-protein interaction or protein-protein interaction to elucidate the small molecules mechanism of action or the protein targeted by the small molecule. In some embodiments, the photo-click tags comprise a photo-conjugation moiety and a click chemistry handle, allowing for the attachment of various functional groups (e.g., affinity tags) to the small molecule or amino acid analog.
