Novel antitumor agents CI-920,PD113,270 and PD113,271. II. Isolation and characterization.

Abstract
A complex of structurally related compounds that exhibit in vivo antileukemic activity [in mice] was isolated from fermentation broths of a new streptomycete. The components of this complex are water soluble phosphate esters containing a conjugated triene system. The isolation and characterization of 3 of these components are described.
