Description
United States Patent 3,138,588 17-KETALS 0F ESTRONE AND DERIVATIVES THEREOF Herchel Smith, Wayne, Pa., assignor to American Home Products Corporation, New York, N.Y., a corporation of Delaware No Drawing. Filed Aug. 24, 1962, Ser. No. 219,135 10 Claims. (Cl. 260-239.5)
The present invention relates in general to certain new and novel 17-ketals of estrone, 3-substituted ethers and esters thereof, methods of preparing and pharmaceutical preparations containing the same.
The novel compounds of the invention may be considered by reference to the general structure:
wherein R represents a substituent selected from the group consisting of hydrogen, lower alkyl, lower alkenyl, cycloalkyl, lower aralkyl, and acyl; and W represents a member selected from the group consisting of alkylenedioxyme'thylene, alkylenethioxymethylene and alkylenedithiomethylene, with the provision that when W is alkylenethioxymethylene R must be other than hydrogen; and if alkyl must contain at least 2 carbon atoms therein when W is alkylenedioxymethylene.
In the above definition of the general class of compounds of the invention, the term lower alkyl is intended to refer to those alkyl groups having from 1 to about 20 carbon atoms and more particularly to those having less than 10 carbon atoms. The alkyl group may be normal or branched in structure, although the normal chain is generally preferred. Some examples of these would be methyl, ethyl, propyl, isopropyl, butyl, isobutyl, pentyl, octyl, dodecyl, and cetyl, to name a few. The term lower cycloalkyl refers to that substituent wherein the carbon atoms are joined in a carbocyclic ring which is generally 5 or 6 membered, but which may contain a smaller or larger number of carbon atoms subject to the practical limit of stability of such structures. The term lower aralkyl as employed herein refers in general to an alkyl substituted aromatic ring structure, which alkyl group may contain up to about 20 carbon atoms. An example of this type of substituent would be for instance benzyl, phenylethyl, phenylisopropyl, and the like. The term acyl as employed herein refers to a substituent derived from a mono-, di-, or poly-carboxylic organic acid which may be saturated or unsaturated. These radicals are, of course, obtained from any suitable organic acid by removal of a hydroxyl group therefrom. Such acyl radicals as the alkanoyl radicals acetyl and propionyl derived from acetic and propionic acids respectively and the aryoyl radical benzoyl derived from benzoic acid would therefore serve as examples of this type of substituent.
The ketal substituent present as W in the l7-position of this novel class of compounds is considered to be an essential element of such structures. It is intended by the definition of alkylenedioxymethylene, alkylenethioxymethylene and alkylenedithiomethylene as employed herein to define W to embrace any and all forms of such ketals which can contain up to about 10 carbon atoms but preferably about 2 to 6 carbon atoms therein. These ketals can be of the closed or open chain type, both of which would behave in a similar manner. The term alkylenethioxymethylene involves those ketal substituents 3,138,588 Patented June 23, 1964 ice.
c we -(U. r ill In the above reaction the known compound estrone (or 3-substituted estrone) represented by structure (I) is reacted with a mole equivalent quantity of a suitable ketalizing agent such as an alkylene glycol and acid combination such as p-toluenesulfonic acid or polyphosphoric or the like in an inert solvent at the reflux temperature of the solvent. The corresponding 17-ketal (II) is obtained which is then treated with a suitable alkylating, alkenylating, etc. agent to transform the hydroxy group in the 3-position to a corresponding 3-substituent as above defined for structure (III).
In this method of preparation in the above reaction schemes where it is desired to prepare the 17-substituted hemithioketal instead of the alkylenedioxy type a reagent such as thioethanol is substituted for alkylene glycol in the ketalizing step of the synthesis. In the same manner where the dithioketal is desired, a reagent such as ethanedithiol is substituted for the alkylene glycol employed in the ketalizing steps. As an alternative and generally more direct method of preparation the 3-ether or ester or estrone is directly ketalized to the 17-ketal in the presence of an inert solvent such as benzene, chloroform, pyridine, etc. at a reaction temperature limited only by the reflux temperature of the solvent over a period of from about 2 to 24 hours duration to complete ketalization In the preparation of the l7-ketals of the invention as illustrated above only one of a plurality of possible methods of ketalization has been disclosed. It should be understood that within the general framework of the invention other alternative means of ketal formation may be employed if desired. For instance the process of 17- ketalization to form these novel compounds may be carried out by an exchange reaction which is known as exchange ketalization. In this method the 17-ketone to be ketalized is contacted with the ketal of another carbonyl compound such as the ethylene ketal of acetone, methylethylketone, mesityl oxide or the like in the presence of an acidic catalyst to effect a transfer of the ketal function from the latter compound to the former one.
This reaction may be conducted either in the presence or absence of heating as specific conditions dictate.
It should further be noted that the present invention also comprehends the preparation of so-called open chain 17-ketals wherein the carbon atoms attached to the oxygen or sulfur atoms are not in fact joined together. However, the preparation of compounds such as these will become clear to those skilled in the art after consideration of the foregoing disclosure.
The compounds of the invention are useful in the field of experimental pharmacology as well as being valuable as intermediates for further steroid synthesis in preparing new steroidal compounds. In addition, many of the compounds of the invention have been found to demonstrate high antilipemic properties coupled with low feminizing action. Also, besides having capacity to regulate blood lipids, the compounds are useful for their general hormonal effect, particularly in the female. Therefore many of the compounds would be expected to exhibit utility in those areas where estrogens are employed, such as female hypogonadism, amenorrhea, dysmenorrhea, metrorrhagia, ovulation block and contraception, pregnancy maintenance, Mteriosclerosis, osteoporosis, menopausal symptoms, infertility, regulation of water balance, functional uterine bleeding, and the like.
The novel compounds of the invention when contemplated for use in pharmaceutical products may be employed in combination, if desired, with a large number of compatible diluents, carriers and the like to form a pharmaceutical composition. Such liquid carriers as mineral oil or a lower aliphatic alcohol may be used where injectables are to be prepared. Glycerine or the like may be used where a syrup is to be used to administer the compound. Carboxymethylcellulose, starches, sugars and the like may be employed where tablets or powders are to be employed as a means of administration. The dosage of the compounds will vary with the severity of the ailment and in general can vary from 0.5 to 100 nag/kilo of body weight per day depending upon the many factors of the case involved.
The invention will be further illustrated by the several following examples of preparation of selected members of the series. It is, of course, to be understood that these examples are purely by way of illustration and are not intended to limit the scope of the invention in any manner. For a legal definition of the proper scope of the invention attention is directed to the several appended claims.
