Physarorubinic acid, a polyenoyltetramic acid type plasmodial pigment from the slime mold Physarum polycephalum (myxomycetes)

Alexander Nowak, Bert Steffan

Abstract

Abstract The polyenoyltetramic acid physarorubinic acid (2) has been isolated from microplasmodia of the slime mold Physarum polycephalum. The structure was elucidated by means of 1D‐ and 2D‐NMR, IR, and UV spectroscopy and mass spectrometry. The stereochemistry was proven by synthesis of the tetramic acid unit and application of circular dichroism. It was shown that plasmodia of a white mutant strain also contain yellow pigments.
