Abstract
Description
- This application is divisional of U.S. application Ser. No. 10/551,772, filed Oct. 3, 2005, which is a 371 application of PCT EP04/03005, filed Mar. 23, 2005.
- The present invention relates to vegetable extracts from Ferula spp and to a process for isolating ferutinine from said extracts.
- Numerous Ferula genus plants contain terpenes with estrogenic activity, known also as phytoestrogens, i.e. substances which regulate hormonal functions and are apparently a valid alternative to the use of synthetic hormones in the treatment of pre-menstrual syndrome and disorders related to menopause and aging. Extracts of some types of Ferula were used in ancient times as contraceptives and in the treatment of impotence and menopausal disorders. Recently, alcoholic extracts from Ferula asafoetida L. have been disclosed (WO 0230438) as anticancer drugs.
- The most abundant compounds in Ferula genus plants are derivatives of jaeschkenadiol (II):
- in particular daucane esters having the general formula (I)
- Daucane esters are known compounds and are for example disclosed in Phytochemistry, vol. 37, n°3, pages 597-623, 1994. In the formula (I) R is a straight or branched, saturated or unsaturated aliphatic acyl residue, or an optionally substituted aromatic acyl residue. Examples of R groups are iso-valeroyl, angeloyl, benzoyl, p-hydroxybenzyl, veratroyl or cinnammoyl.
- Daucane esters from Ferula spp are estrogen modulators similar to SERMs (selective estrogen receptor modulators); among them, ferutinine (Ia) shows marked estrogenic activity, whereas the others have a rather mild activity.
- In particular, ferutinine is an estrogen receptor alpha agonist (αERα) and an estrogen receptor beta agonist/antagonist (ERβ). It has also been shown that ferutinine has higher binding to estrogen receptors than tamoxifen.
- There is therefore the need to obtain ferutinine-enriched extracts or optimise the extraction of ferutinine in the pure form from plant materials containing its precursors.
- A process comprising the hydrolysis of a daucane esters whole extract to give crude jaeschkenadiol and the subsequent re-esterification of jaeschkenadiol with suitably protected p-hydroxybenzoic acid, for example with p-acetoxybenzoic acid, is known from the literature (J. Org. Chem. USSR (Engl. Transl.); EN; 28; 10; 1992; 1666-1673). Nevertheless, this process gives rather poor yields (about 45%), mainly due to competitive transesterification reactions.
- It has now been found that the use of p-pivaloyloxybenzoic acid as esterifying agent allows to avoid competitive reactions responsible for low conversion yields.
- Object of the present invention is therefore a process for the preparation of ferutinine (Ia)
- which comprises the following steps:
- a) extraction of daucane esters from Ferula spp;
- b) basic hydrolysis of daucane esters to give jaeschkenadiol (II)
- c) esterification of jaeschkenadiol (II) with p-pivaloyloxybenzoic acid (III)
- to give p-pivaloyloxyferutinine (IV)
- d) hydrolysis of p-pivaloyloxyferutinine (IV) to ferutinine.
- “Daucane esters” means compounds of the general formula (I) as defined above; said esters can be obtained by extraction of the rhizomes or aerial parts of Ferula spp, preferably Ferula communis and Ferula hermonis, with conventional methods, for example by extraction with lower alcohols. Starting from Ferula hermonis rhizomes containing ferutinine and jaeschkenadiol benzoic ester (not easily separable by chromatography) in 1:1 ratio, pure ferutinine can be isolated by extracting the roots with methanol, treating the extract with 5% KOH and back-extracting the saponified extract with aliphatic hydrocarbons, ethers, esters or chlorinated solvents.
- Alternatively, daucane esters can be obtained by extraction with supercritical CO2 at temperatures ranging from 35 to 65° C., preferably at 45° C., and pressures ranging from 200 to 260 bar, preferably at 245 bar. In the separator (or in the separators) the temperature ranges from 25 to 45° C. and the pressure is of about 50 bar. In these experimental conditions gummy materials, which make the recovery of the desired compounds difficult, are not extracted. The residue can be directly submitted to saponification according to what reported in the examples.
- Jaeschkenadiol is esterified with p-pivaloylossibenzoic acid and treated, in the same reaction solvent, with a base, preferably a primary amine, more preferably ethylenediamine, to give pure ferutinine. According to a preferred embodiment of the invention, steps c) and d) are conveniently carried out in sequence without recovery of intermediate p-pivaloyloxyferutinine.
- A further object of the present invention is the cosmetic and dermatological use of ferutinine, p-pivaloyloxyferutinine and extracts, of Ferula spp, preferably Ferula communis and Ferula hermonis extracts.
- When applied on the skin, ferutinine and Ferula spp extracts surprisingly proved able to increase collagen biosynthesis and to exert a tonic, trophic and moisturizing action, thus giving firmness and elasticity. Moreover, they reduce sebum secretion and play a remarkable role in the control of hirsutism and face virilization. Therefore, compositions containing ferutinine or Ferula spp extracts can be used in the cosmetic or dermatological field for the treatment of superficial or deep wrinkles or other iunaesthetisms, as well as for the treatment of various acne and seborrhea forms.
- Ferutinine and Ferula spp extracts can be formulated in the form of creams, gels and lotions in admixture with conventional excipients, for example those described in Remington's Pharmaceutical Sciences Handbook, XVII ed., Mack Pub., N.Y., U.S.A., preferably in the presence of soy lecithin or phospholipids, such as lauroylphosphatidylcoline and myristoylphosphatidilcoline, which can be incorporated in water/oil and oil/water emulsions or in transdermal plasters.
- The following examples illustrate the invention in greater detail.
- 250 g of finely ground Ferula hermonis roots (particle size distribution: 2 mm) are extracted by percolation with 1 l MeOH. After maceration for two days and percolation of the solvent, the operation is repeated (4×1 l), to obtain 112.2 g of methanol extract (45%). Drug exhaustion is monitored by TLC (petroleum ether/EtOAc 8/2, ferutinine Rf: 0.14).
- The methanol extract is refluxed with 513 ml of a 10% KOH methanol solution. After 1 h, TLC analysis (petroleum ether-EtOAc 8/2, ferutinine Rf: 0.14; Rf jaeschkenadiol: 0.31) shows that the reaction is complete. After cooling, the reaction mixture is diluted with water (500 ml) and extracted with petroleum ether (4×500 ml). The combined petroleum ether phases are washed with brine, dried and evaporated. The resulting semicrystalline residue is washed with cold petroleum ether (refrigerator temperature) to obtain 7.5 g of crystalline jaeschkenadiol. The mother liquors are purified by chromatography (50 g silica gel, petroleum-ether-EtOAc 95:5), to obtain α-bisabolol (870 mg), a mixture of α-bisabolol and jaeschkenadiol, and pure jaeschkenadiol (3.4 g after crystallization). The mixture of jaeschkenadiol and α-bisabolol is pooled with the mother liquor and chromatographed (50 g silica gel, petroleum ether-EtOAc 95:5), to obtain 1.95 g of crystalline jaeschkenadiol (overall yield: 12.85 g, 5.1%).
- The compound has the following chemical-physical and spectroscopic properties:
- IR spectrum (KBr, cm−1): 3339, 2965, 2905, 2875, 1470, 1375, 1047, 968, 858

- 250 g of finely ground Ferula communis roots (particle size distribution: 2 mm) are extracted by percolation using 1 l MeOH. After maceration for two days and percolation of the solvent, the operation is repeated (4×1 l); the methanol extracts are concentrated to a volume equal to the weight of the ground roots and the extract is added with 10% KOH (10 ml). The alkaline solution is refluxed for 2 hours, then cooled and back-extracted three times with 200 ml of n-hexane. Drug exhaustion is monitored by TLC (petroleum ether/EtOAc 8/2).
- The combined hexane phases are washed with brine, dried and evaporated. The resulting semicrystalline residue is washed with cold petroleum ether (refrigerator temperature), to obtain 3.5 g of crystalline jaeschkenadiol. The mother liquor is purified according to example 1. Yield: 0.8 g of jaeschkenadiol having the same chemical-physical properties as that of example 1.
- 1 kg of finely ground Ferula communis aerial parts are extracted with carbon dioxide at 45° C. and 245 bar in an apparatus for extraction with supercritical gases. In the separator (or in the separators) temperature ranges from 25 to 45° C. and pressure is of about 50 bar. In these conditions gummy materials that make it difficult to recover the desired compounds are not extracted. The residue, which contains only lipophilic compounds and water, is taken up with methanol and treated with bases to hydrolyse jaeschkenadiol esters, as reported in examples 1 and 2. After purification, 5.1 g of pure compound having the same characteristics of the product of example 1 is obtained.

The study was preceded by a seven days conditioning period, wherein the subject had to refrain from the use of moisturizing products, sun-creams and liquid make-ups and to avoid tanning treatments and excessive exposition to UV rays.
- The subjects were allowed to use conventional eye and lip care products, face powders and non moisturizing soaps.
- The subjects were randomly divided into two groups, one treated with a placebo cream and one treated with the cream of example 7. The creams were applied on the face in standardized amount (0.5 g, i.e. 0.5 cm of cream coming out of the tube) twice a day, morning and night. Before and after five weeks of treatment the following measurements were carried out.
- Before each measurement session all the subjects stayed for thirty minutes in a climatic chamber at 23° C. and 50% of relative humidity. Each session comprised three measurements with corneometer, three measurements with cutometer, and a silicon impression of the periorbital area, on the skin areas indicated in the following.
- All the 40 subjects completed the study.
- Cutometer is a commercially available device (Cutometer SEM 575, Courage & Khazaka, Germany) for measuring skin mechanical properties in a non-invasive way. In more detail, it measures the vertical deformation of the skin surface when subjected to a negative pressure of 500 mm Hg through a 2 mm opening of a probe. The length of skin penetration in the probe is optically measured with 0.01 mm precision. The probe is connected with a computer that registers skin deformation over time. From the resulting curve, numerous variables can be extrapolated to evaluate skin elastic, viscoelastic and viscous behaviour.
- The following parametres were recorded:
- immediate distension (Ue), measured at 0.1 seconds;
- delayed distension (Uv);
- final distension (Uf), measured at 10 seconds; and
- immediate retraction (Ur).
- The test was carried out using the cutometer on both cheeks.
- Significant variations were not observed in the placebo group. Delayed distention (Uv) in the treated group significantly decreased (16%, p<0.05) after 5 weeks treatment. This parameter reflects skin viscoelastic properties and dermis behaviour. After 5 weeks, a significant change was also observed (−12%, p<0.05) in Ue, which is mainly influenced by hydration and mechanic properties of the corneum layer. The decrease in Uv and Ue, together with Ur stability, shows increased skin firmness.
- Soft and smooth skin appearance mostly depends on the presence of an adequate amount of water in the corneous layer.
- Corneometer is a commercially available device (Corneometer CM 825 Combi 3, Courage & Khazaka, Germany) which measures capacitance changes resulting from changes in skin hydration.
- The test was carried out using the corneometer on both cheeks.
- After 5 weeks, a significant change in the treated group was observed, in particular, skin hydration increased by 17.5%, while in the placebo group it decreased by 3%.
- Silicon impressions were carried out on subjects in the seated position. The impressions (2×5 cm) were obtained at the beginning and after 5 weeks, using “Silflo silicon impression material” (available from Flexico, UK).
- The impressions were then analysed with the Skin Image Analyzer system using the Quantirides-Monaderm software, which distinguishes cutaneous microrelief from median wrinkles and deep wrinkles and calculate their number and depth; finally, the value of total wrinkle area is obtained.
- After 5 weeks, significant changes were observed in the treated group. In particular, a 21.3% (p<0.05) decrease in the wrinkle area was observed, whereas in the placebo group the decrease was 0.4%.
- Statistically significant decrease has been observed mainly in the number and depth of median and deep wrinkles.
- The study allowed to conclude that the cream of example 7 has good cosmetic activity in the treatment of skin with chrono- and photoaging signs, as it increases skin firmness and hydration and decreases mean wrinkled area, in particular deep micro- and macrorugosities. Skin visibly appeared firmer and smoother.
