Dihydrolindbladiones, three new naphthoquinone pigments from a myxomycete Lindbladia tubulina
Abstract
Three new naphthoquinone pigments, 6,7-dimethoxydihydrolindbladione (1), dihydrolindbladione (2), and 6-methoxydihydrolindbladione (3), have been isolated from a myxomycete Lindbladia tubulina, and their structures were elucidated by spectral data. Compound 3 appreciably exhibited a reversal effect of multidrug resistance. Lindbladione (4), the major pigment of this myxomycete, was also isolated from Cribraria intricata.
