摘要:
The invention relates to the natural substance cyclamenol of the formula ##STR1## a process for its preparation from microorganisms of the order of the Actinomycetales, in particular from the Streptomyces strain MHW 846, chemical derivatives thereof, and its use as a medicament, in particular for acute and chronic inflammatory disorders in human and veterinary medicine.
摘要:
The present invention relates to the use of microbiologically prepared compounds and their mixtures, which are called efomycins, as performance promoters in farm animals and processes for their preparation, and furthermore new efomycins and their mixtures as new chemical compounds. The invention also relates to microorganisms which can be used for the preparation of the efomycins and their mixtures.
摘要:
An animal growth promoter, efomycin G, is obtained by culturing Streptomycetes strain BS 1261. Efomycin G has the following properties:(a) The empirical formula: C.sub.53 H.sub.86 O.sub.18(b) The mass spectrum (fast atom bombardment) Molecular weight+Na.sup.+ : 1033(c) The .sup.1 H-nuclear magnetic resonance spectrum, stated in parts per million, shown in FIG. 1.(d) The .sup.13 C-nuclear magnetic resonance spectrum, stated in parts per million shown in FIG. 2, with chemical shifts of the CC-NMR signals as follows:______________________________________ 170.0 77.9 65.9 32.9 7.0 145.4 73.4 48.5 19.4 144.7 71.2 43.6 19.1 131.9 70.6 41.9 16.8 121.1 70.1 41.1 16.7 99.6 69.9 38.8 15.1 99.5 66.9 38.5 13.4 93.6 66.5 36.2 9.0 93.3 66.4 33.0 8.9 ______________________________________ (ppm values are relative to tetramethylsilane at 0 ppm) (e) A UV absorption maximum at 251-254 nm in methanolic solution(f) The structure according to FIG. 3.
摘要:
The invention relates to substituted dibenz-oxa-thiocinone-12-oxides and -12,12-dioxides of the general formula I ##STR1## in which R.sup.1 to R.sup.6 and Y have the meaning indicated in the description, to processes for their preparation and to their use in medicaments, in particular in circulation-influencing medicaments.
摘要:
New cyclic depsipeptides having 18 ring atoms, of the general formula (I) ##STR1## in which R represents hydrogen, straight-chain or branched or cyclic alkyl having up to 8 carbon atoms, and their optical isomers and racemates,and their use for combating endoparasites in the field of medicine and veterinary medicine.
