Definitions

  • Liarozole is a racemic mixture, i.e. a mixture of its optical isomers, and is specifically mentioned as compound 28 in EP-0,371,559. Said patent application mentions the use of compounds like liarozole in the treatment of epithelial disorders.
  • EP-0,260,744 describes the use of compounds like liarozole for inhibiting or lowering androgen formation.
  • EP-0,371,559 and EP-0,260,744 recognize that compounds like liarozole have stereochemically isomeric forms, no example of an enantiomerically pure form is given of liarozole.
  • Chemically liarozole is ( ⁇ )-5-[3-chlorophenyl]-lH-imidazol-l-ylmethyl]-lH-benz- imidazole, and is represented by formula (I). As can be seen from the chemical structure, liarozole has one stereogenic center (indicated with an asterisk in formula (I)).
  • the subject of this invention is the enantiomerically pure dextrorotatory isomer or (+)-isomer of liarozole. Said isomer will hereinafter be referred to as (+)-liarozole.
  • (+) and (-) or d and 1 are employed to designate the sign of rotation of plane-polarized light by the compound, with (-) or 1 meaning that the compound is iaevorotatory and with (+) or d meaning that the compound is dextrorotatory.
  • the optically active isomers having an opposite sign of optical rotation are called enantiomers.
  • Said enantiomers are identical except that they are mirror images of one another.
  • a 1: 1 -mixture of such enantiomers is called a racemic mixture.
  • Stereochemical purity is of importance in the field of pharmaceuticals since the respective enantiomers may have a different potency or may have a different activity.
  • the enantiomer of a beneficial isomer may even be deleterious rather that simply inert. Several examples of such differences are known in the art.
  • enantiomerically pure means that the product contains at least 90% by weight of one enantiomer and 10% by weight or less of the other enantiomer. In the most preferred embodiment the term “enantiomerically pure” means that the composition contains at least 99% by weight of one enantiomer and 1% or less of the other enantiomer.
  • the intermediate with the same absolute configuration of the stereocenter as the desired enantiomer of the final product will be designated with the prefix (B) before the reference number.
  • the pharmaceutically acceptable acid addition salts as mentioned hereinabove are meant to comprise the therapeutically active non-toxic acid addition salt forms which the compounds of formula (I) are able to form.
  • the latter can conveniently be obtained by treating the base form with such appropriate acids as inorganic acids, for example, hydrohalic acids, e.g. hydrochloric, hydrobromic and the like; sulfuric acid; nitric acid; phosphoric acid and the like; or organic acids, for example, acetic, propanoic, hydroxyacetic, 2-hydroxypropanoic,

  • salt form can be converted by treatment with alkali into the free base form.
  • addition salt also comprises the hydrates and solvent addition forms which the compounds of formula (I) are able to form. Examples of such forms are e.g. hydrates, alcoholates and the like.
  • Preferred pharmaceutically acceptable acids are hydrochloric acid and (E)-2-butenedioic acid.
  • Enantiomerically pure (+)-liarozole may be prepared by reacting an enantiomerically pure intermediate diamine of formula (B)-(II) with formic acid or a functional derivative thereof.
  • Said functional derivative of formic acid is meant to comprise the halide, anhydride, amide and ester, including the ortho and imino ester form thereof. Also methanimidamide or an acid addition salt thereof can be used as cyclizing agent.
  • the enantiomerically pure intermediate diamine of formula (B)-(II) may be prepared by reducing an intermediate of formula (B)-(i ⁇ ) by a standard nitro-to-amine reduction reaction.
  • the desired enantiomer of the intermediate of formula (B)-(]H) can be prepared by fractional crystallization of a racemic mixture of the intermediate of formula (HI) with an enantiomerically pure chiral acid.
  • Preferred chiral acid for the above fractional crystallization is 7,7-dimethyl-2-oxobicyclo[2.2.1]heptane-l-methanesulfonic acid (i.e. 10-camphorsulfonic acid).
  • Appropriate solvents for carrying out said fractional crystallization are water, ketones, e.g. 2-propane, 2-butanone; alcohols, e.g. methanol, ethanol, 2-propanol.

  • Liarozole has retinoid mimetic effects in vivo and in vitro. This means that the compound is thought to inhibit retinoic acid (RA) catabolism, so that increased retinoic acid (RA) levels lead to pronounced RA effects at the tissue or cell level. Liarozole has also been shown to be a potent inhibitor of androgen biosynthesis. Preclinical and clinical studies are ongoing showing the utility of liarozole in the field of oncology and dermatology.
  • (+)-liarozole shows increased retinoic mimetic activity when compared with racemic liarozole or with the enantiomerically pure leavorotat ⁇ ry isomer of liarozole, hereinafter referred to as (-)-liarozole. More in particular, (+)-liarozole is a stronger inhibitor of the retinoic acid metabolism in human skin epidermis and human tongue squamous carcinoma cells (SCC25). Moreover, the increased effectiveness of (+)-liarozole as a retinoic mimetic, especially in the field of dermatology, can be evidenced by the test "Induction of Pinnal Epidermal Hyperplasia in Hairless Mice".
  • (+)-liarozole The effect of retinoic acid at the level of normal human keratinocytes is also more potentiated by (+)-liarozole. Furthermore, it has been found from toxicity tests that, unexpectedly, the use of (+)-liarozole is more suitable, when compared to (-)-liarozole, for the manufacture of a medicament for treating keratinization disorders.
  • the increased retinoic mimetic activity of (+)-liarozole is described in more detail in the experimental part hereinafter. From the above, it can be conceived that by administering an effective amount of (+)-liarozole it is possible to accomplish a more "targeted” dermatological therapy.
  • a more "targeted” dermatological therapy means that by using the (+)-isomer of liarozole, the compound is used which has a higher retinoic mimetic activity.
  • (+)-Liarozole and its pharmaceutically acceptable acid addition salts is therefore useful in a method of treating disorders which are characterized by an increased proliferation and or abnormal differentiation of epithelial cells.
  • (+)-Liarozole shows activity on cells of which the growth and differentiation is not substantially mediated by or insensitive to the actions of androgens or estrogens, in particular on cells of which the growth and differentiation is sensitive to the actions of retinoids.
  • Special uses include the ability to cure and/or reduce a variety of disorders of keratinization such as, for example, rosacea, acne, psoriasis, ichthyosis, warts, callosites, acanthosis nigricans, lichen planus, corneal epithelial abrasion, geographic tongue, Fox-Fordyce disease, precancerous skin conditions, such as, actinic keratoses, and keloids, epidermolytic hyperkeratosis, Darter's disease, pityriasis rubra pilaris, congenital ichthyosiform erythroderma, hyperkeratosis palmaris et plantaris, melasma, hyperpigmentation.
  • (+)-Liarozole and its pharmaceutically acceptable acid addition salts is useful for the manufacture of a medicine for treating keratinization disorders.
  • an effective amount to treat disorders which are characterized by an excessive proliferation and/or abnormal differentiation of tissues would be from 0.001 mg/kg to 20 mg/kg body weight and more preferably from 0.01 mg kg to 10 mg kg body weight.
