Definitions
- the present invention relates to hop extracts, processes for their production and use of o-fenext clock cycles for the prophylaxis and therapy of disease states which are caused by a lack of estrogens or by dysregulations of the sex hormone metabolism, in particular the estrogen metabolism ,
- hops because of its bitter and aromatic substances, it is crucial for the taste of the beer. In addition, because of their antimicrobial properties, these substances have a certain importance in the preservation of beer.
- Xanthohumol 1 numerous other flavon-type compounds were found in the hop plant (JF Stevens et al., Phytochemistry 44, 1575-1585 (1997), JF Stevens et al., J. Chromat. A 832 (1-2), 97-107 ( 1999)). These are primarily isoprenylated flavonoids such as. B. 6- or 8-prenylnaringenin 2 and 3 and isoxanthohumol 4. Stevens et al. (Phytochemistry 53, 759-775 (2000)) also examined the chemotaxonomy of hop species and hop taxa.
- JP 08 165238 (ref. CA 125: 158632) describes the estrogen-agonistic activity of a number of 8-prenylated flavone derivatives, including 8-prenylnaringenin.
- hop flavonoids especially xanthohumol 1
- xanthohumol 1 can affect cell metabolism. They are able to positively influence enzyme reactions that play an important role in the formation of tumor cells. These compounds can thus be viewed as cancer preventives (conference of the German Society for Hop Research, state of knowledge on the hop ingredient xanthohumol, March 24, 1998, Aschheim).
- Miranda et al. Food Chem. Tox. 37 (4), 271-285 (1999) reported strong antiproliferative activity of xanthohumol 1 and isoxanthohumol 4 on human MCF-7 breast cancer cells, as well as on HAT-29 colon and A-2780 ovarian cancer cell lines ,
- WO 83/00701 A1 claims a process for the production of estrogen-active substances from hops, characterized in that a carbon dioxide extract is first prepared from hops with the addition of water as an entrainer and then the estrogen-active substances are obtained therefrom by means of ether extraction or chromatographic processes , Furthermore, the use of these substances as an additive to animal feed, for cosmetic products or as a bath additive is claimed. No information is given about the nature of these estrogenic substances.
- WO 01/30961 AI claims a process for obtaining stable beer brewing additives, characterized in that the hop droppings residue from the carbon dioxide extraction is extracted with a polar solvent, preferably hot water, and the extract is then acidified with a non-polar solvent , preferably hexane, washed and - if necessary after drying - used as a brewing additive. The remaining spent grain is discarded.
- a polar solvent preferably hot water

- Another object of the invention is to provide a method for producing such extracts and these comprehensive pharmaceutical preparations which are suitable for the treatment of the abovementioned disease states.
- the present invention is based, inter alia, on the surprising finding that extracts which still contain the phloroglucinol-like hop bitter acids are obtained from hop drug after removal of lipophilic and hydrophilic fiber, and at the same time free and / or bound chalcones and flavones such as xanthohumol, isoxanthohumol and 6- and 8-prenylnaringenin, however, contained in an enriched form.
- Particularly surprising is the fact that the content of 6- and 8-prenylnaringenin depends on the temperature of the water pre-extraction (see Example 3) and can be increased up to a factor of about 2.
- Figure 1 illustrates the dependence of the concentration of the analyzed ingredients on the temperature of the water pre-extraction.
- Such an extract can be selected by one or more extraction with a C 5 ⁇ C 7 alkane or with supercritical C0 2 (degreasing stage), subsequent extraction of the remaining drug residue with water and subsequent extraction of the remaining drug residue with a medium polar solvent group consisting of alcohols, aqueous alcohols, ketones, aqueous ketones, esters and possibly subsequent liquid-liquid distribution.
- a medium polar solvent group consisting of alcohols, aqueous alcohols, ketones, aqueous ketones, esters and possibly subsequent liquid-liquid distribution.
- the hop bitter acids do not completely, but only partially, in the lipophilic extract, while on the other hand, the chalcones and flavones remain almost completely in the drug residue during water extraction. This makes it possible to obtain a hop extract that contains all the pharmacologically relevant ingredients (bitter acids, chalcones, flavones) in a balanced ratio. Due to this favorable combination of several therapeutic principles, this extract can be used ideally for disease conditions that are caused by
- the hop extracts according to the invention are suitable for the prophylaxis and treatment of symptoms associated with the menopause or postmenopause in women, the symptoms including hot flashes, depression, anxiety, mental confusion, sleeplessness and serious health problems associated with postmenopause such as osteoporosis, cardiovascular disease. diseases, stroke, dementia and tumor diseases. Other diseases which are based on dysregulation of the sex hormone metabolism and can be treated with the extract according to the invention are, for example, amenorrhea, anovulatory cycles, menometrorrhea, premenstrual complaints and postpartum depression. Likewise, these extracts can be used to treat sex hormone-dependent diseases in men, such as benign prostatic hyperplasia or prostate cancer.
- the surprisingly high estrogenic activity of the hop extracts according to the invention was demonstrated both in a competitive receptor binding assay for the human estrogen receptors alpha and beta and in a recombinant yeast assay compared to the activity of 17 ⁇ -estradiol.
- conventional standard hop extracts show much weaker activity or no activity at the same dosage.
- FIG. 2 shows the activity of a comparative extract and two hop extracts according to the invention in a yeast reporter gene assay.
- a hop extract is provided with a content of free and / or bound chalcones and flavones, in particular 6- and 8-prenylnaringenin, xanthohumol and isoxanthohumol, which is higher than that of conventional, in particular aqueous-alcoholic extracts, and which at the same time also contains ⁇ - and possibly ⁇ -bitter acids ( Humulon or Lupulon and its derivatives) contains.
