Abstract:
The present invention relates to compounds of the formula (I): which are produced by the plant Garcinia punctata, chemical derivatives derived therefrom, a process for their preparation, and their use as pharmaceuticals, in particular for the treatment and/or prophylaxis of bacterial infectious diseases.
Abstract:
The present invention relates to compounds of the formula (I) which are formed by the microorganism ST 003236 (DSM 14476) during fermentation, to a process for preparing and derivatizing them, to a pharmaceutical which comprises a compound of the formula (I) and to the use thereof for producing a pharmaceutical.
Abstract:
The invention relates to novel peptide derivatives, called memno peptides, of the formula (I): wherein R1, R2, R3, R4, R5, R6, R7, R8 and (A)n have the meaning herein, obtainable by cultivation of Memnoniella echinata FH2272, DSM 13195 or mutants and variants of this, a process for their preparation and the use of the compounds as pharmaceuticals, for example against cardiac insufficiency.
Abstract:
The invention relates to compounds of the formula I AcPhe-Aib-Aib-Aib-x-w-Leu-y-Aib-Hyp-Gln-z-Hyp-Aib-Pro-R (I) in which R is Phe-ol or Phe-al and w, x, y, and z have the following meanings: a) w is Gly or Ala; x is Aib and y and z are Iva; b) w is Gly; x, y and z are Iva; c) w is Gly; x and z are Aib and y is Iva; d) w is Gly; x, y and z are Aib; or e) w is Gly; x and y are Aib and z is Iva; or of the formula II AcPhe-Iva-Gln-Aib-lle-Thr-Aib-Leu-Aib-x-Gln-Aib-Hyp-Aib-Pro-Phe-Ser, (II) wherein x is Hyp or Pro, which are synthesized by Acremonium tubakii FH 1685 DSM 12774 during fermentation and released into the culture medium, a process for the isolation of the cephaibols from the culture medium, and their purification, and the use of the cephaibols as pharmacologically active compounds, in particular for the control of parasites.
