Lactimidomycin, isolated from Streptomyces, is an inhibitor of eukaryotic translation elongation. It is also a potent and non-toxic inhibitor of dengue virus 2 and other RNA viruses. Lactimidomycin has an antiproliferative effect on tumor cell lines. It i
Nagilactone C and phyllanthoside are novel protein synthesis inhibitors, they are specific for the eukaryotic translation apparatus, function in vivo and in vitro, and interfere with translation elongation. Nagilactone C shows high insecticidal activity against second-instar nymphs of Eocanthecona furcellata. Nagilactone C possesses potent antiproliferative activity against human fibrosarcoma and murine colon carcinoma tumor cell lines exhibiting ED50 values of 2.3 and 1.2 microg/ml, respectively.
