The closely related antibiotics diumycin A and B, with monomeric molecular weights of approximately 1800 daltons in ethanol, aggregate in aqueous buffers to form particles with a molecular weight (mol. wt.) of at least 32,000 daltons. The aggregate of diumycin is essentially unaffected by esterifica

β¦ Synopsis
The structures of diumycinol (l), isodiumycinol (2), and diumycene (3), the nonisoprenoid C1s lipids obtained by acid hydrolysis of the antibiotic diumycin, have been determined by analysis of spectral data and the identification of a number of degradation products. Examination of the ORD of a degradation product gave the absolute configuration of the asymmetric center in these compounds.
