Pharmaceutical and cosmetic compositions containing as an active component 10-acetyl-1,8,9-triacetoxy anthracene

Abstract

Pharmaceutical and cosmetic compositions contain as the active component 10-acetyl-1,8,9-triacetoxy anthracene.

Description

The present invention relates to new pharmaceutical and cosmetic compositions, particularly anti-inflammatory compositions, containing as the active component 10-acetyl-1,8,9-triacetoxy anthracene.

10-acetyl-1,8,9-triacetoxy anthracene has been prepared and described by 0.E. Schultz and H. Schultz-Mosgau, Archiv der Pharmazie, 298 313-320 (1965).

10-acetyl-1,8,9-triacetoxy anthracene has the formula ##STR1##

It is provided in the form of a crystallized solid having a melting point of 206.degree. C.

It has now been discovered that this component possesses anti-inflammatory properties. It can be used in cosmetology principally for body and hair hygiene or in therapeutics or in dermo-pharmacy, particularly to inhibit abnormal proliferation of cells observed in disorders such as psoriasis, or warts, and also as an anti-inflammatory agent in the treatment of rheumatism, dermatosis, eczema, seborrheic and pellicular poll evil, and sunburns.

The present invention also relates to new pharmaceutical or cosmetic compositions characterized the the fact that they contain, as the active component, 10-acetyl-1,8,9-triacetoxy anthracene.

These compositions contain the active component in combination with an appropriate vehicle for administration, enterally, topically or parenterally. In these compositions, the concentration of the active component generally ranges from 0.01 to 70 percent by weight, generally as a function of the form of administration or application selected.

Compositions administered enterally or parenterally can be provided in the form of tablets, granules, gelules, capsules, syrups, drinkable suspensions, packeted ingestible powders, or even in the form of injectable solutions or suspensions.

For topical application, the compositions of the present invention can be provided in the form of ointments, unguents, creams, gels, sprays, suspensions, micronized powders, tinctures, solutions, lotions or shampoos.

These compositions can also contain inert adjuvants, for example, binders, fillers, diluents, thickening agents, preservatives, UVA and UVB filters, anti-oxidants and the like, or even biologically active additives.

The compositions administered orally can also contain sapidity agents.

These pharmaceutical compositions are prepared in accordance with conventional procedures.

The posology varies particularly as a function of the disorder being treated and the method of administration selected. For enteral or parenteral administration, generally from 0.005 to 5 g of the active component are administered daily to an adult, in one or several doses.

For topical application, 1 to 5 g, for example of a formulation containing from 0.01 to 5 g of the active component per 100 g of the composition are applied.

Because of the anti-inflammatory properties of the compound of formula I, the compositions of the present invention can be employed particularly in the treatment of eczema, psoriasis, rheumatism, dermatosis, warts, seborrheic and pellicular poll evil and sunburns.

The present invention also relates to a medicine packaged and prepared industrially, characterized by the fact that it comprises a pharmaceutical composition such as defined above, in an appropriate container provided with a label indentifying the method of administration recommended for the treatment of inflammatory disorders.

The present invention also relates to the use of the compound of formula I (also referred to herein as compound I) in the industrial preparation of a packaged medicine such as defined above.

The following non-limiting examples illustrate the present invention.

EXAMPLE 6

Antitumoral activity study on lymphocytic leukemia P 388

The principle of the test is the following:

There is implanted in a mouse, at day 0, a tumor by intraperitoneal injection of 10.sup.6 tumoral cells in 0.1 ml of ascitic, diluted fluid. The tumoral cells were leukemia lymphocytes (strain P 388). The treatment consists in administering intraperitoneally and daily the product studied, for 5 days following the implantation of the tumor, at various dosages.

The results of the test are set forth in Table I.

TABLE I______________________________________Activity mg/kgPosology Animals tested, TAnimals control, CMedian time of survival (in days) ##STR2##______________________________________3.12 12.3 9.9 1241.56 11.8 9.9 1190.79 11.4 9.9 115______________________________________

A product is considered active in this test when: T/C.times.100>120.

This study shows that the compound of formula I is active at a dosage near 3 mg/kg.

EXAMPLE 7

Study of the antitumoral activity on melanocarcinoma B 16

The principle of the test is as follows:

A mouse is implanted at day 0, with a tumor by injecting it intraperitoneally with 0.5 ml of a diluted (1/10) homogeneate of the selected tumor. The treatment consists in administering the product studied, daily and intraperitoneally, for 9 days following the implantation of the tumor.

A product is considered active, according to this test, when the ratio T/C.times.100>125.

It has been found that the optimum dose of 10-acetyl1,8,9-triacetoxy anthracene is near 6 mg/kg (for 6 mg/kg, T/C.times.100=150)

EXAMPLE 8

Study of the anti-inflammatory activity

The method used is that described by M. J. H. Smith and J. R. Walker in the British Journal of Pharmacology (198), 69, 473-478.

This method constitutes a test of chemokinese of the polymorphonuclears (category of white corpuscles) of rabbit. The chemokinese is stimulated by a chemotactic agent (fMLP* 1mM). The inhibition, caused by the product being studied at increasing dosages, is studied. There is then determined the K.sub.0.5 value (in micromoles/liter) which corresponds to a 50% reduction of the maximum stimulation given by only fMLB 1mM. * fMLP is formylmethionyl leucylphenylalanine.

With compound I: K.sub.0.5 =36 micromoles/liter.

EXAMPLE 9

Study of the antiproliferative activity on fibroblasts

The method used is that described by Jacques and Reichert in the British Journal of Dermatology 105, Supplement 20, pp. 45-48 (1981).

This method consists in evaluating the cytostatic activity of the product on fibroblasts by studying the inhibition of the incorporation of tritiated thymidine in a culture of fibroblasts of human skin.

The product studied is added at various increasing concentrations. The dose K.sub.0.5 is determined which is the dose, expressed in micromoles/liter, necessary for a 50% reduction, relative to non-treated cultures, of the incorporation of tritiated thymidine.

With compound I, it has been found that K0.5 =1 micromole/liter.
