Background of the Invention:
The present invention relates to topical application of Compounds A, B, C, D, series and methyl 5-<3, 6-dihydro-1(2H)-pyridyl>-2-oxo-2H-<1, 2, 4> oxadiazolo 2,3,-α> pyrimidine-7-carbamate and their active analogs and derivatives for improving the rate of hair growth on mammalian skins and for the treatment of alopecia, as well as the use of the forementioned compounds and their analogs with retinoids.
A normal characteristic of hair growth in mammals, including human, is that in most cases the rate of hair growth and the length of its growth cycle are reduced with age. These phenomena are common to all mammals with rare exceptions and they must be differentiated from true male pattern alopecia.
United States Patent No. 4,139,619 issued to Charles A. Chidsey on February 13, 1979 discloses a process for stimulating the growth of mammalian hair by topical application of certain preparations containing, as the active ingredient, 6-amino-4 (substituted amino)-1,2-dehydro-1-hydroxy-2-iminopyrimidine. This patent further states that the active compounds and the methods of their preparations are disclosed in United States Patent No. 3,461,461, which was issued on August 12, 1969. Most examples in the patent to Chidsey describe various preparations such as topical cream, topical ointment, solution, aerosol and dusting powder, and state that these preparations can be applied to the bald human scalp to stimulate the rate of growth of terminal hair.
International Application Numbers PCT/US81/00338 and PCT/US82/01593 by applicant Gail Bazzanσ disclose chemical compositions containing retinoids and retinoids and minoxidil which can be used to increase the rate of growth of hair and to treat alopecias.
It is the object of the present invention to provide additional compositions or preparations which are effective in improving the rate of hair growth on mammalian skin, as described and listed on Pages 9,10,11 of this patent application.
It is also the object of this invention to provide such compositions for topical applications to mammalian skin, in combination with retinoids, in order to stimulate or improve the rate of hair growth thereon and to prolong the anagen phase of the hair cycle.
The foregoing and other objects and advantageous features of this invention will be more clearly comprehended from the following detailed description.
Detailed Description of the Invention:
It has been unexpectedly discovered that the subject compounds, when applied to a mammalian skin, in an effective amount, stimulate or improve the rate of hair growth and prolong the anagen phase of the hair cycle. Moreover, these compounds have also been found to be effective in treatment of alopecia. Typically, these compounds constitute the active
ingredients of different types of preparations such as lotions, solutions, ointments, creams, sprays and the like.
The compounds of the present invention which form the active ingredients in the hair treatment preparations include Compounds A, B, C, D, series and methyl 5-<3, 6-dihydro-1(2H)-pyridyl-2-oxo-2H—<1 , 2, 4>oxadiaolo<2, 3-α>pyrimidine-7-carbamate or their active derivatives or analogs. Furthermore, combinations of these compounds with retinoids as described in PCT U.S./00338 and PCT U.S. 82/01593 exhibit synergism in that they improve or stimulate the rate of hair growth to a greater extent than the individual active ingredients of the combination alone.
Suitable retinoid active ingredients for use in this invention include derivatives of retinoic acid which have been described in PCT applications: U.S. 81/00338 and U.S. 82/01593.
Preparations such as lotions, creams, conditioners, and the like, including the aforementioned compounds as the active ingredients, can be applied topically to the skin for stimulating or improving the rate of hair growth. It has surprisingly been discovered that the compounds of the present invention, in comparison with minoxidil, when applied topically to the skin have excellent penetration and a long lasting effect, in producing hair growth in an animal model for androgenetic alopecia. Furthermore, retinoids in combination with the subject compounds of this application exhibit synergism in the animal model studied.
As used herein, the term retinoid denotes retinol, retinal, retinyl esters as well as retinoic acid and its esters, amides, derivatives, analogs and metabolites. As described in PCT U.S. 82/01593, the terminal groups may be oxidized, reduced, esterifled, etc. The alkali metal (sodium, potassium, etc.) and alkaline earth metals (magnesium, zinc, calcium, etc.) salts of these compounds are also included herein.
The pharmaceutical, cosmetic or veterinary preparations of the present invention can be prepared by conventional techniques for the preparation of lotions, creams, conditioners or shampoos for the scalp or veterinary preparations for pelis. Included also are preparations which can be administered orally and compounds which can be added to animal foods.
In addition to the active compounds of this invention, the various preparations can contain any conventional pharmaceutically acceptable or cosmetically acceptable inert or pharmacodynamically active additives or carriers. For example, the lotions may be prepared using various forms of alcohols or other solubilizers such as glycols, or esters. The conditioners may contain the normally acceptable commercially produced compounds such as cetyl alcohol, ceteareth-5, -20 hydrantoins, hydrolyzed animal protein, blycol stearate, amodimethicone, paraffin, mineral oil, etc. The topical compounds may also contain various oils including essential fatty acids and phospholipids and other polyunsaturated fatty acids and their derivatives and. prostaglandins and prostacyclins and their derivatives and analogs and other compounds which can be vasodilators, vitamins or hormones. The topically applied lotions, creams, and conditioners, etc., will vary according to the standard art with regard to the amounts of other hydrophilic and hydrophobic containing ingredients, including emulsifiers, so that either an oily, semi-oily or oil-free product may be obtained. The shampoos may contain any of the conventionally used detergents or soaps and any other compounds used by those familiar with the art. Oil-based shampoos are included in these formulations.
The topical treatments may consist of lotions, creams, conditioners, shampoos, oil treatments, etc., with from 0.001 to 5% by weight of the active ingredients, Compounds A, B, C, D, series and all-trans retinoic acid or derivatives, or other retinoids, as the preferred dosages in these compositions.
