title: TMC-205 a new transcriptional up-regulator of SV40 promoter produced by an unidentified fungus. Fermentation, isolation, physico-chemical properties, structural determination and biological activities.
abstract: A new transcriptional up-regulator designated TMC-205 was discovered from the fermentation broth of an unidentified fungal strain TC 1630 by using an SV40 promoter-luciferase reporter assay. Based on spectroscopic analyses, its structure was determined to be (E)-6-(3-methyl-1,3-butadienyl)- H-indole-3-carboxylic acid. Expression of the luciferase activity was activated ca. 2-, 4-, and 6-fold by 1, 10, and 100 microM TMC-205, respectively. TMC-205 activated the transcriptional activity in a manner dependent on the presence of the enhancer element of SV40 in its promoter region.
