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
Haemanthamine is an alkaloid isolated from the Amaryllidaceae plants with potent anticancer activity. It inhibits protein biosynthesis during the elongation stage of translation. It has antimalarial, pro-apoptotic, antiviral, antioxidant, and anticonvulsa
Cytochalasin E is a potent actin depolymerization agent and an epoxide containing Aspergillus-derived fungal metabolite. Cytochalasin E also inhibits angiogenesis and tumor growth. It binds and caps the barbed end of actin filaments to prevent actin elong
Monocerin is a fungal metabolite that has been found inF. larvarumand has diverse biological activities.1,2,3It is active against the bacteriaE. coliandB. megaterium, the phytopathogenic fungusM. violaceum, and the algaC. fuscain an agar diffusion assay when used at a concentration of 50 μg/disc.1Monocerin (17.5 μg/ml) induces mortality in adultC. erythrocephala.2It reduces root elongation in pre-germinatedS. halepenseseeds when used at a concentration of 33 ppm.3
