Definitions
- TITLE MEDICINAL PRODUCT COMPRISING THIOURAE FOR ITS USE AS A DEPIGMENTANT OR ANTIMUTAGENIC AND ANTICARCINOGENIC AGENT
- the present invention relates to medicaments containing thioureas or their mono or dioxid derivatives, in particular having a depigmenting action, but also as an antimutagenic and / or anticarcinogenic agent.
- melanocytes Skin pigmentation in humans comes from a complex series of cellular processes that take place in a single population of cells called melanocytes.
- Melanocytes are located in the lower part of the epidemic, and their function is to synthesize a brown pigment, melanin, which protects the body from the damaging effects of ultraviolet radiation.
- Melanin is deposited in the melanosomes, vesicles present inside the melanocytes.
- Melanosomes are expelled from melanocytes and transported to the surface of the skin by keratinocytes, which assimilate the melanin contained in the melanosomes.
- the dark shade of the skin is proportional to the amount of melanin synthesized by the melanocytes and transferred to the keratinocytes. In some cases, it is better to reduce or inhibit melanogenesis, for example, to lighten the skin, to remove age spots or to reduce the hyperactivity of melanocytes.
- Isothiocyanates and thiocyanates have also been described as depigmenting (WO 02/058664).
- 1,3-bis- (5-methanesulf ⁇ nylbutyl) thiourea is known to be one of the degradation products of sulforaphane (isothiocyanate having depigmenting activity: WO 02/058664) during prolonged contact with water, and in particular with hot water by the following process:
- Mutagenesis occurs in DNA and in cell development spontaneously or naturally, or as a side effect due to chemicals, high energy radiation, stress, etc.
- Mutagens are agents that cause such mutations. They are also often carcinogenic (i.e. capable of inducing cancer).
- Today's society is now aware of and concerned by the presence of mutagens in its environment. Mutagens are ubiquitous; some are naturally present in plants, many others are produced by the combustion of organic materials (especially during cooking), and others are produced by industry.
- the population is faced with many health problems. Many of these health problems are the result of damage to cells and DNA in the human body caused by mutagens and also by mutagenic factors, factors that contribute to increased damage to cells and DNA.
- mutagens and mutagenesis factors include among others pollution, stress, aging, cigarette smoke, ultraviolet light, excessive exercise, tissue damage, etc.
- diseases resulting from cell damage and DNA we can cite: aging, age spots, cancer, cataracts, dry skin, fatigue, skin cancer, damage caused by stress and wrinkles.
- compositions exist to induce antimutagenic activity inside the body, they sometimes have significant side effects.
- the present invention therefore relates to a medicament comprising at least one thiourea of general formula I below: I in which: n is an integer between 1 and 12, m is an integer between 1 and 12,
- Ri, R 2 , R and R independently of one another represent a hydrogen atom, a C ⁇ -C 6 alkyl group or an aryl group, or at least one of its mono or dioxid derivatives of general formulas Ha , ITb and
- C ⁇ -C 6 alkyl group is meant in the sense of the present invention any alkyl group of 1 to 6 carbon atoms, linear or branched, in particular, the group CH 3 .
- aryl group in the sense of the present invention one or more aromatic rings having 5 to 8 carbon atoms, which can be joined or fused.
- the aryl groups can be phenyl or naphthyl groups and can be substituted by halogen atoms, alkyl groups as defined above, the OH group or the nitro group.
- the thioureas according to the present invention are either commercially available or can be prepared, for example for 1,3-bis (5-methanesulfinylbutyl) -thiourea, by thermal degradation of sulforaphane.
- the mono or dioxid derivatives can be obtained from the corresponding non-oxidized thiourea by the action of an oxidizing agent such as, for example, hydrogen peroxide.
- the medicament according to the present invention is useful for inhibiting tyrosinase, in particular reducing by 50% the action of tyrosinase, inhibiting the synthesis of melanin, reducing the hyperactivity of melanocytes.
- the medicament according to the present invention is useful as an antimutagenic agent, in particular with respect to mutagenic substances and / or with respect to UVB, and / or as an anticarcinogenic agent .
- this drug can prevent the appearance of cancers, in particular skin cancers, age spots, aging, in particular that of the skin, and wrinkles.
- the present invention also relates to cosmetic compositions comprising at least one thiourea, according to the present invention, of general formula I below:
- n is an integer between 1 and 12
- m is an integer between 1 and 12
- Ri, R, R and 1 ⁇ independently of one another represent a hydrogen atom, a C ⁇ -C 6 alkyl group or an aryl group, or at least one of its mono or dioxid derivatives of general formulas Ha , Ilb and III below:
- this cosmetic composition is a depigmenting composition. It can be used to lighten, whiten or depigment the epidermis, remove skin spots, especially from old age or freckles, or prevent pigmentation of the epidermis.
- this composition is intended for topical administration.
- the medicament or the cosmetic composition according to the present invention is in a form for oral or topical use, advantageously for topical use.
- He or she may be in the forms which are usually known for this type of administration, that is to say in particular lotions, mousses, gels, dispersions, sprays, serums, masks, body milks. or creams, for example, with excipients allowing in particular skin penetration in order to improve the properties and accessibility of the active principle.
- These compositions generally contain, in addition to the drug or the cosmetic active agent according to the present invention, a physiologically acceptable medium, generally based on water or on a solvent, for example alcohols, ethers or glycols.
- They can also contain surfactants, preservatives, stabilizing agents, emulsifiers, thickeners, other active ingredients leading to a complementary or possibly synergistic effect, trace elements, essential oils, perfumes, dyes, collagen, chemical or mineral filters, moisturizers or thermal waters.
- the present invention also relates to a cosmetic treatment of the skin by applying to the skin a cosmetic composition according to the present invention.
- a suspension of 25 g of lithium aluminum hydride in 400 ml of ethyl ether is prepared.
- the suspension is then neutralized by slowly adding 80 ml of distilled water under reflux. When the boiling stops, 120 ml of distilled water are then added to complete the neutralization of the remaining hydride. Filter on sintered glass.
- the NMR spectra of the proton and of carbon 13 were obtained on a Brucker AM 200 SY apparatus at 200 MHz for the proton, 50.3 MHz for the carbon. Chemical shifts are indicated in part per million (ppm) relative to the signal of the deuterated chloroform CDC13 at 7.25 ppm for the proton and 76.9 ppm (central line of deuterochloroform) for the carbon.
- the mass spectra were obtained on a Normag / SIDAR V 2.3 device by chemical ionization (NH) or electronic impact techniques.
- compositions of the different solutions used are as follows:
- the inhibitory molecules are dissolved directly in the pH 6.8 buffer, in 50% methanol (methanol - distilled water) or in pure methanol depending on their solubility.
- the weight-by-volume concentrations of the different inhibitor solutions are: 0.2%, 0.1%, 0.05%, 0.025%, 0.0125%, 0.00625% and 0.00312%.
- tyrosinase The action of tyrosinase is evaluated by the initial speed of the reaction measured on the D.O.
- the initial rates of the reactions without inhibitors (concentration 0) and the rates at the various concentrations tested are plotted on a curve.
- the inhibitory power of a molecule is defined as the concentration which reduces the action of tyrosinase by 50%.
- the reading is done for 3 minutes and the percentage of inhibition is calculated (inhibition speed and saturation plateau).
- the bis MSoBT produced in the manner indicated above inhibits the enzymatic activity of tyrosinase by 50% at concentration of 8.3 mM final
- the kojic acid shows the same percentage of inhibition at the concentration of 0.670 mM final.
- the low solubility in water of bis MSiBT and MSBMSBT did not allow these molecules to be tested for their anti-tyrosinase effect.
- Example 6 Study of the depigmenting effect of bis MSiBT, MSBMSBT and bis MSoBT in comparison with koiic acid and dimethylthiourea
- the bis MSiBT, MSBMSBT and bis MSoBT molecules were also tested on melanocyte - human keratinocyte melanin co-cultures in order to test their depigmenting effect on a living system representing the melanization unit as it exists in the skin. functional human.
- the pigmented epidermis (black phenotype / co-culture of normal keratinocytes and melanocytes at the air-liquid interface) originate and are cultured according to the recommendations of MatteKcorporation, USA. Culture media are also provided by this manufacturer.
- the products (kjjic acid 35 mM, dimethylthiourea 2.8 mM obtained from the company Aldrich ref.: D 18,870-0, bis
- MSiBT 2.8 mM obtained by the method indicated above, MSBMSBT 2.8 mM obtained by the method indicated above and bis MSoBT obtained by the method indicated above 2.8 mM) are applied in the culture medium for 21 days.
- the depigmenting effect is evaluated by extracting melanin from the culture wells.
- the extraction is carried out on a pool of two culture wells which are homogenized in 0.45 ml of sodium dodecyl sulfate (SDS) at 1% containing 0.05 mM of EDTA and 10 mM of Tris Hcl (amino-2- (hydroxymethyl) -2-propanediol-
- SDS sodium dodecyl sulfate
- bis MSiBT manifests a weaker depigmenting activity than MSBMSBT and especially that bis MSoBT, the concentration of which is necessary to obtain approximately 30% inhibition is 25 times lower than for kojic acid. which is the reference molecule widely used in the trade of products intended to lighten the skin.
- the products according to the present invention therefore have a depigmenting activity.
- the Vitotox test is based on bacteria containing the lux operon of Vibrio fisheri under the transcriptional control of the mutated recN promoter (controlled by the SOS system of the bacteria). After incubation of the bacteria with a genotoxic product, the recN promoter is depressed and the lux operon is expressed: light emission, emission which is proportional to the genotoxicity of the product. Certain products act directly on the production of light or increase the metabolism of bacteria, creating false positives. Also, a bacterial strain, having a constitutive lux operon is used in control. This same strain is used as a cytoxicity control (false negatives).
- Example 7.1 evaluation of the antimutagenic effect of bis MsoBT vis-à-vis MMS (methylmethanesulfonate)
- a genotoxic molecule is used, methylmethanesulfonate (MMS) which is compared to the genotoxicity of a mixture of reference mutagenic molecules, 4-nitroquinoline oxide and benzo (a) pyrene.
- MMS methylmethanesulfonate
- the MMS is placed alone or as a mixture with the bis MsoBT at increasing concentrations and the light emissions are compared. We can then define an inhibitory concentration 50 of mutagenesis.
- Cultures of Salmonella typhimurium TA 104 recN2-4 (for the genotoxicity test) and Salmonella typhimurium TA 104 prl (for the cytotoxicity test) in Nutrient Broth medium 8 g / L are produced and then incubated at 37 ° C. agitation overnight (OD between 0.2 and 0.5 for bacteria for the genotoxicity test and between 0.4 and 0.6 for bacteria for the cytotoxicity test). The next day, the bacteria for the genotoxicity test are diluted 1/10 with Nutrient Broth medium and with Vi for the bacteria for the cytotoxicity test.
- a stock solution of MMS at 90 mM in H 2 O was prepared and serial dilutions at '/ 2 plate 96 are performed.
- the reference genotoxic products (4-nitroquinolineoxide (NQO) / benzo (a) pyrene (BAP)) are used at 0.4 ppm for NQO and 800 ppm for BAP).
- the product to be tested is used with or without metabolic activation (fraction S9: microsomal homogenate containing cytochrome P450: 2.45 mL / mL final).
- the light emission kinetics as a function of the genotoxicity and the cytotoxicity of the product, is measured for 3 hours (measurements every 5 minutes) with a Fluoroskan Ascent FL (ThermoLabsystems).
- the products are supplied by the Sigma - Aldrich companies.
- Bis MsoBT has a concentration 50 inhibiting the mutagenic effect of MMS of 17 p.p.m without S9 and 20 p.p.m with S9.
- the bacterial cultures are irradiated for a period allowing an average emission of 20 light units (RLU).
- RLU light units
- the bis MsoBT is then placed at increasing concentrations in the culture medium before irradiation and an inhibitory concentration 50 is determined.
- Example 2 The procedure is as in Example 1 but without MMS and by irradiating the bacterial cultures for 20 s with UVB 254 nm. Under these conditions, MsoBT has a concentration 50 inhibiting the mutagenic effect induced by UV B of 25 p.p.m.
