    摘要: Substances WB2663A, WB2663B and WB2663C are produced by culturing a WB2663-producing bacterium belonging to the genus Pseudomonas to form physiologically active substances and isolating therefrom neutral substances respectively having the following specific rotation: [α]²³ = -36° (C =0.5 in CH₂Cl₂),[α]²³ = -12° (C =0.5 in CH₂Cl₂), and [α]²³ = -9° (C =0.5 in CH₂Cl₂). They have each an excellent antitumor activity.
