In 1995, we discovered new antiherpetic antibiotics, called fattiviracins. The producing organism was classified as a strain belonging to Streptomyces microflavus. The strain produced at least 13 fattiviracin derivatives (FV-1 to FV-13). Fattiviracin

A novel inhibitor of topoisomerase II designated as 2070-DTI was isolated from the culture filtrate of Streptomyces sp. strain No. 2070. The structure was determined to be that of the known soyasaponin I on the basis of spectroscopic methods (NMR and

Streptomyces microflavus strain No. 2445 produces many derivatives of fattiviracin antibiotics. The major product of these derivatives is fattiviracin FV-8, which consists of four glucose and two trihydroxy fatty acid residues. We found that this str

The inhibitory effects of various fatty acids on topoisomerases were examined, and their structure activity relationships and mechanism of action were studied. Saturated fatty acids (C6:0 to C22:0) did not inhibit topoisomerase I, but cis-unsaturated
