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 1Dโ€ and 2Dโ€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.

From plasmodia of the slime mould Physarum polycephalum a yellow pigment physarochrome A (1) has been obtained. Its structure has been established as all-trans N-[ll-~2-acetylamino-3-hydroxyphenyl)-2,4,6,8,1O-undecapentaenoyl]-S-glutami(l) ij;, the basis of spectroscopic evidence and hydrogenation t
