摘要:
Bafilomycins of the formula ##STR1## in which R.sup.1 is hydrogen or CH.sub.3, andR.sup.2 is hydrogen, or the group ##STR2## are produced by culturing certain streptomyces, e.g. Tu 1922, Tu 2437 and Tu 2599. Those wherein at least one of the OH groups is acylated are new. The compounds are pesticidally active.
摘要:
The invention relates to the new antibiotic Lysolipin including two components X and I, and derivatives thereof. Lysolipin is formed when the strain Streptomyces violaceoniger (Waksman et Curtis) Waksman et Henrici Tu 96, which strain has been deposited under the reference NRRL 8097 at the Northern Regional Laboratory, U.S. Department of Agriculture, Peoria, Illinois, is cultured in a nutrient medium. The structural formulae of the 2 components are ##STR1## Lysolipin I and X and their derivatives have antibacterial activity and are effective against yeast - like fungi, such as Candida albicans. Their antibiotic action probably depends on an inhibition of the cell wall synthesis.
