詳細

詳細

A cell-permeable semicabazone compound that prevents B. anthrax Lethal toxin/LT (EC₅₀ = 1.7 µM in RAW264.7 cultures; EC_max = 6 µM in murine BMDM cultures), diphtheria toxin/DT, P. aeruginosa ExoA, and H. ducreyi cytolethal distending toxin (Hd-CDT) from exerting their cytotoxic activity, but not endocytic uptake, by blocking endosomal trafficking/maturation into acidified late endosomes, while exhibiting no cytoprotective efficacy against ricin & E. coli Ec-CDT that do not require acidified endosomes for intoxication. Likewise, EGA is also shown to inhibit low-pH-dependent viral infectivity by Armstrong strain of LCMV, A/WSN/33 strain of influenza virus, but not low-pH-independent infection of Nipah virus NiV or MLV. Although the exact molecular target remains unknown, EGA does not act as a pH neutralizing agent, nor does it inhibit endosomal recycling or trafficking to phagocytic compartments.

Likewise, EGA is also shown to inhibit low-pH-dependent viral infectivity by Armstrong strain of LCMV, A/WSN/33 strain of influenza virus, vesicular stomatitis virus VSV-pseudotyped lentivirus & VSV-pseudotyped MLV, but not low-pH-independent infection of Nipah virus NiV or MLV. Although the exact molecular target remains unknown, EGA does not act as a pH neutralizing agent, nor does it inhibit endosomal recycling or trafficking to phagocytic compartments.
