Abstract
New antibiotics, resorcinomycins A and B, were isolated from the culture broth of a streptomycete strain identified as Streptoverticillium roseoverticillatum. The antibiotics are water-soluble amphoteric substances, positive to SAKAGUCHI'S reagent. The molecular formulas C14H20N4O5 and C13H18N4O5 for A and B were indicated by elemental analysis and secondary ion MS. The structures of these antibiotics were determined by 1H and 13C NMR spectrometry and some chemical evidences to be N-[(S)-alpha-guanidino-3,5-dihydroxy-4-isopropylphenylacetyl]glyci ne and N-[(S)-alpha-guanidino-3,5-dihydroxy-4-ethylphenylacetyl]-glycine, respectively.Entities:
