Definitions
- the present invention relates to the use of at least one cucurbit seed oil chosen from the group consisting of Lagenaria, Luffa and Momordica, for the preparation of a composition intended to inhibit the activity of 5 ⁇ -reductase, as well as the use of such an oil for the preparation of a composition intended for the treatment of prostatic hypertrophy, prostatic adenoma, acne, hyperseborrhea, alopecia, and hirsutism.
- the invention also relates to cosmetic treatment methods, in particular for oily skin.
- the subject of the invention is also the use of at least one oil of cucurbit seeds in a food for humans and / or animals as an additive acting to inhibit the activity of 5-alpha reductase.
- the tropical cucurbits belonging to the three genera Lagenaria, Luffa and Momordica are plants cultivated in particular on Reunion Island or in India.
- these tropical cucurbits one can cite in particular the long calabashes, scabies and bottle (Lagenaria leucaritha), the ribbed pipangaille (Luffa acutanguld), the smooth pipangaille (Luffa cylindrica) and the margoze (Momordica charantia).
- Calabashes of the genus Lagenaria leucaritha are plants generally cultivated in Asia, especially in China and Japan. They are also found around the Indian Ocean. These plants are annual herbaceous plants from 8 to 10 meters. The fertilization of their flowers leads to cylindrical fruits, swollen at their base, called calabashes. There are, for example, on the island of Reunion, three types of gourds of the genus Lagenaria leucaritha, the long gourds, scabies and bottle. These fleshy fruits contain in their center flat and elongated seeds with a lipid content of between 12 and 25% by weight.
- the margoze of the genus Momordica charantia comes from India but is also cultivated on the island of Reunion. It is an annual herb, which can give lianas of 2 meters, and whose oblong fruits of green color contain flat seeds. The lipid content of these seeds is approximately 30% by weight.
- patent application EP 359 196 describes cosmetic formulations for the treatment of the skin, comprising at least one adjuvant and from 1 to 90% by weight of an extract of luffa cylindrica, the extract being an aqueous or alcoholic extract. obtained for example by percolation.
- the oil extracted from the seeds of tropical cucurbits advantageously chosen from the group consisting of Lagenaria leucaritha, Luffa acutangula, Luffa cylindrica and Momordica charantia
- a cosmetic composition advantageously administered by topical external route, intended to inhibit the activity of 5-alpha reductase and to act in particular on oily or shiny skin or hair, on skin prone to acne, on the areas of the scalp affected by alopecia of non-pathological origin or on areas of the skin with excess hairiness.
- oils extracted from the seeds of tropical cucurbits appear to be cosmetically acceptable compounds, non-aggressive for the skin, non-toxic and hypoallergenic.
- the Applicant has also surprisingly discovered that the oil extracted from the seeds of tropical cucurbits according to the present invention could be used in a pharmaceutical or food composition intended to inhibit the activity of 5-alpha reductase.
- 5 ⁇ -reductase is a microsomal NADPH dependent enzyme which exists in the form of two isoenzymes synthesized from two different genes.
- the type 1 isoenzyme of 5-reductase is found mainly in the liver and skin, more particularly in the sebaceous glands of non-genital skin and scalp, and appears at puberty.
- the type 2 isoenzyme is predominant in the prostate and in the skin of the differentiated sexual territories: genital area, beard, and plays a role in sexual differentiation.
- the distribution of type 1 and 2 isoenzymes of 5 ⁇ -reductase in the skin and the cutaneous appendages in humans can be illustrated by the following table 1.
- Table 1 Distribution of type 1 and 2 isoenzymes of 5 ⁇ -reductase in the skin and skin appendages in humans
- this enzyme 5 ⁇ -reductase mainly located in the genital tissues and in the skin, catalyzes the hydroxylation of testosterone to 5 ⁇ -reductase dihydrotestosterone (DHT).
- DHT 5 ⁇ -reductase dihydrotestosterone
- Too high 5 ⁇ -reductase activity therefore causes too much androgen in the form of DHT elevated in the prostate, resulting in overstimulation of the latter resulting in an undesirable growth which can lead to the pathology of prostatic hypertrophy, or even to prostatic adenoma, most often requiring surgical intervention.
- Other pathologies, of dermatological type can be observed in men or women as resulting from an overactivity of 5 ⁇ -reductase, namely, in particular acne, hirsutism or even alopecia.
- the activity of 5-reductase is greater in the sebaceous gland than in other structures.
- the seborrheic glands show a more active 5 ⁇ -reductase than those in other skin areas. Therefore, the level of physiological sebaceous secretion seems closely related to the activity of this enzyme.
- Oily skin in addition to its unsightly appearance, constitutes a field on which complications can arise. It reaches the areas where the sebaceous glands are numerous and results mainly from an androgenic overstimulation of the sebaceous production by these specific glands. Hyperseborrhea participates in the occurrence of acne vulgaris lesions.
- the type 1 isoenzyme of 5 ⁇ -reductase in the sebaceous glands, as well as in the hair follicle.
- the 5 ⁇ -reductase type 2 isoenzyme is localized mainly at the level of the internal epithelial sheath, as well as at the level of the dermal papilla of the hair. However, this latter location remains to be specified.
- Androgenic alopecia whose pathophysiology is very close to that of acne, is the most common alopecia and probably the one where the demand for therapy is the highest. 5 ⁇ -reductase seems to play a key role in this pathology. In fact, men suffering from a genetic deficiency in the 5cc-reductase type 2 isoenzyme do not develop androgenetic alopecia. In view of the above, research has focused on the development of 5 ⁇ -reductase inhibitors. Some steroids like progesterone have been tested for this, but its rapid metabolism makes it ineffective in vivo. To be active, the 5 ⁇ -reductase inhibitor must be stable enough to block the activity of the enzyme in vitro.
- Finasteride a competitive steroidal inhibitor, fulfills this condition, but it is more active on the type 2 isoenzyme than on the type 1 isoenzyme and these two isoenzymes have only 50% homology on the sequence of their acids. amines. It is therefore especially in benign prostatic hyperplasia that finasteride has already been tested.
- Serenoa Repens extract is also known, as a reference as a 5 ⁇ -reductase inhibitor, the Serenoa Repens extract having the advantage, compared to the finasteride, of being of natural origin in as a plant extract allowing a better comparison for tested products also of natural origin.
- Serenoa Repens also known as Sabal serrulatum, is a small palm that can be found in the United States (Florida) in North Africa and in Spain.
- the Applicant has now found, quite surprisingly and unexpectedly, that the use of the oil extracted from cucurbit seeds chosen from the group consisting of Lagenaria, Luffa and Momordica allows a remarkable inhibition effect to be obtained. the activity of 5 ⁇ -reductase, thus in particular providing a new response for the treatment of the dermatological pathologies and / or disorders mentioned above.
