摘要:
This invention describes the new 9α-substituted estratrienes of general formula I in which R3, R7, R7′, R13, R16 as well as R17 and R17′ have the meanings that are indicated in the description and R9 means a straight-chain or branched-chain, optionally partially or completely halogenated alkenyl radical with 2 to 6 carbon atoms, an ethinyl or prop-1-inyl radical, as pharmaceutical active ingredients that exhibit in vitro a higher affinity to estrogen receptor preparations from rat prostates than to estrogen receptor preparations from rat uteri and in vivo preferably a preferential action on the ovary in comparison to the uterus, their production, their therapeutic use and pharmaceutical dispensing forms that contain the new compounds.The invention also describes the use of these compounds for treating estrogen-deficiency-induced diseases and conditions.

摘要:
The invention describes new compounds as pharmaceutical active ingredients, which have in vitro a higher affinity to estrogen receptor preparations from rat prostates than to estrogen receptor preparations from rat uteri and in vivo a preferential action on bone rather than the uterus, their production, their therapeutic use and pharmaceutical dispensing forms that contain the new compounds. The new compounds are 16α- and 16β-hydroxy-estra-1,3,5(10)-estratrienes, which carry additional substituents on the steroid skeleton and can have one or more additional double bonds in the B-, C- and/or D-rings.

摘要:
This invention relates to new 19-nor-17α-pregna-1,3,5(10)-trien-17β-ols with a 21,16α-lactone ring with a long-chain substituent in 11β-position of general formula II in which R11 means a straight-chain alkyl radical with 6 to 17 carbon atoms, and R3 and R13 have the meanings that are explained in more detail in the description. The compounds act in a tissue-selective manner as pure antiestrogens and are suitable for the production of pharmaceutical agents because of these properties.
摘要:
The present invention makes available prodrugs of 9α-substituted oestratrienes of the general formula (I) in which the group Z is bonded to the steroid, processes for their preparation, pharmaceutical compositions which comprise these compounds and use thereof. The compounds of the general formula I according to the invention do not bind to the oestrogen receptor a and/or β. They bind to carboanhydrases and inhibit these enzymes.
摘要:
The invention concerns an illumination system for generation of colored, especially amber or red light, comprising a radiation source and a fluorescent material comprising at least one phosphor capable of absorbing a part of light emitted by the radiation source and emitting light of wavelength different from that of the absorbed light; wherein said at least one phosphor is a amber to red emitting a rare earth metal-activated oxonitridoalumosilicate of general formula (Ca1−x−y−zSrxBayMgz)1−n(Al1−a+bBa)Si1−bN3−bOb:REn, wherein 0≦x≦1, 0≦y≦1, 0≦z≦1, 0≦a≦1, 0
摘要:
A phosphor converted light emitting device includes a semiconductor structure comprising a light emitting layer disposed between an n-type region and a p-type region, the light emitting layer being configured to emit light having a first peak wavelength; a first phosphor configured to emit light having a second peak wavelength; and a second phosphor configured to emit light having a third peak wavelength. The second phosphor is an Eu3+-activated phosphor, configured such that in the excitation spectrum at 298K and 1.013 bar, a maximum intensity in a wavelength range between 460 nm and 470 nm is at least 5% of a maximum intensity in a wavelength range between 220 nm to 320 nm.
