title: Novel antitumor agents CI-920, PD 113,270 and PD 113,271. II. Isolation and characterization.
abstract: A complex of structurally related compounds that exhibit in vivo antileukemic activity 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 three of these components are described.
