摘要:
The invention relates to a compound of formula (I) wherein R1 is a sugar; R2 is -CH2-O-(R7)m, R7 representing a sugar, or R2 is -COOH; R3 is an epoxide-comprising group, C1-C6-alkyl or C2-C6-alkenyl, unsubstituted or substituted by at least one OH; R5 is H, C1-C6-alkyl, C2-C6-alkenyl or C2-C6-alkynyl; R4, R6, R8 and R10 independently of one another are H,C1-C6-alkyl, C2-C6-alkenyl, C2-C6-Alkynyl, -X2H, or -X2R12, or R4 and R6 together and/or R8 and R10 together are =X2; X2 is O, NH, N-C1-C6-alkyl, N-C2-C6-alkenyl, N-C2-C6-alkynyl or S; R12 is C1-C6-Alkenyl, C2-C6-alkynyl, C2-C6-alkynyl, aryl or acyl; and m and n are 1 or 2; and its physiologically acceptable salts. The compounds are obtainable from a culture of the microorganism Actinomycetales species HAG 003959, DSM 12931, by fermentation. Accordingly, the invention relates to a process for their preparation and to the use of the compounds as pharmaceuticals, for example as anti-tumor agents.

The present invention relates to novel hydroxyphenyludecane derivatives of the formula (I), a method for the preparation of said compounds by cultivation of the fungus Cryphonectria parasitica, DSM 14453, and their use as pharmaceuticals, i.e. for the treatment of Alzheimer’s Disease, Parkinson’s Disease, Huntington’s Diseases, stroke, psychosis and/or depressions.
摘要:
The invention relates to novel active agents (coniosetin and coniosetin derivatives) of formula I, which are produced by the micro-organism Coniochaeta ellipsoidea Udagawa (DSM 13856) during fermentation, R, R2, R3, R4, R5, X, X2, X3 and X4 having the meanings given. The invention also relates to chemical derivatives of coniosetin, to a method for producing them and to the use of the same as medicaments.
