Synthesis of vaccinia viral antigens in HeLa cells in the presence of isatin beta-thiosemicarbazone.
Vaccinia virus antigens, in HeLa cells treated with the antipox virus drug isatin beta-thiosemicarbazone (IBT), were analyzed by immunoprecipitation, followed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The total radioactivity in the immunoprecipitate was decreased to almost 50% in the presence of the drug as compared to its absence. An inhibition also occurred with an IBT-dep...
متن کاملA case of vaccinia necrosum (or progressive vaccinia), with severe hypogammaglobulinaemia, treated with n-methyl isatin beta-thiosemicarbazone (33T57).
A fatal case of vaccinia necrosum treated with antivaccinial gamma globulin and N-methyl isatin beta-thiosemicarbazone (33T57) is described. Histological abnormalities found at necropsy included intranuclear as well as cytoplasmic inclusion bodies, absence of lymphoid germinal centres, grey hepatization, and bronchiolar epithelial hyperplasia. Virus titres were highest in the original skin lesi...
متن کاملGrowth inhibition by vaccinia virus growth factor.
Vaccinia virus growth factor (VGF), a highly glycosylated 77-residue epidermal growth factor (EGF)-like polypeptide encoded in vaccinia poxvirus, is reported to play an important role in stimulating growth of uninfected cells to facilitate virus infection. We have chemically synthesized the unglycosylated forms of VGF and VGF19-69, a shortened VGF analog consisting of 51 residues and comprising...
متن کاملStudy on the Interaction between Isatin-β-Thiosemicarbazone and Calf Thymus DNA by Spectroscopic Techniques
The interaction between isatin-β-thiosemicarbazone (IBT) and calf thymus DNA (CT-DNA) was investigated in physiological buffer (pH 7.4) using Neutral Red (NR) dye as a spectral probe by UV–Vis absorption and fluorescence spectroscopy, as well as viscosity measurements. The IBT is stabilized by intercalation in the DNA ( K [IBT –DNA] =1.03×105 M−1), and displaces the NR dye from the NR–DNA comple...
