Hk. Lee et al., Topoisomerase I inhibitors from the Streptomyces sp. strain KM86-9B isolated from a marine sponge, ARCH PH RES, 21(6), 1998, pp. 729-733
The crude extract of Streptomyces sp. strain KM86-9B, isolated from a marin
e sponge, displayed significant inhibition on topoisomerase I activity. inv
estigation of the causative components by bioactivity-directed fractionatio
n resulted in the isolation of a series of iso- and anteiso-fatty acids.
