wherein the wavy bond ∼ is either a double bond or the epoxide,
or pharmaceutically acceptable salts, solvates, tautomers, or stereoisomers thereof, for use in the treatment of diseases associated with oxidative stress.
摘要:
Asmarine A and B, novel cytotoxic diterpene-alkaloids, have been isolated from the sponge Raspailia sp. The structure of these compounds have been established on the basis of NMR data and confirmed by X-ray analysis. Also claimed are compounds (I) or (II), wherein R1 represents hydrogen or lower alkyl or lower alkanoyl; R2 represents hydrogen or lower alkyl; R3 is either an alkyl or a cycloalkyl group containing one or more isopreneunits, or a monoterpene or a sesquiterpene or a sesquiterpene or a diterpene group; R4 or R5 represent hydrogen or lower alkyl; R6 represents lower alkyl; X represents F or Cl or Br or (I).
摘要:
New antitumour alkaloids of general formula (I) where R1 is hydrogen, alkyl or acyl and R2 is hydrogen or acyl, include jorumycin, where R1 is hydrogen and R2 is acetyl, extracted from the mollusc Jorunna funebris.
摘要:
The invention provides compounds of formula (1) wherein R1 is a hydrogen atom, an alkyl group having 1 to 6 carbon atoms or an alkoxy group having 1 to 6 carbon atoms; and R2 is a hydrogen atom, an alkyl group having 1 to 6 carbon atoms or an alkoxy group having 1 to 6 carbon atoms; and pharmaceutically acceptable salts thereof. The invention also relates to a process for obtaining the compounds, compositions containing them and their therapeutic use. The compounds display excellent activity against mammalian cancer cell lines.
摘要:
The present invention relates to the use of Collismycin and derivatives thereof as inhibitors of oxidative stress in cells and their use for the preparation of medicaments for the treatment and/or prevention of oxidative stress-induced diseases or conditions, especially neurodegenerative diseases, such as Alzheimer´s Disease and Parkinson's Disease.

摘要:
HA-1 and TH-2, two novel cytotoxic tris(oxazole)-containing macrolides, have been shown. These compounds have been obtained by chemical modification of marine natural products. The structure of these compounds has been established on the basis of NMR data.

摘要:
The present invention relates to the use of some terpenes, for example chlovalicin, ovalicin or fumagillin, as antifungal against Malassezia species and to their use in the manufacture of medicaments for the treatment of human skin diseases caused by these Malassezia species, such as pityriasis versicolor, seborrheic dermatitis, dandruff, atopic dermatitis, psoriasis, confluent and reticulated papillomatosis, onychomycosis, and transient acantholytic dermatosis.
