Those of skill in the treatment of the disorders described hereinabove could determine the effective therapeutic daily amount from the test results presented in the experimental part. An effective therapeutic daily amount would be from about 0.01 mg/kg to about 40 mg/kg body weight, more preferably from about 0.1 mg/kg to about 10 mg/kg body weight. It may be appropriate to administer the therapeutically effective dose once daily or as two, three, four or more sub-doses at appropriate intervals throughout the day. Said sub-doses may be formulated as unit dosage forms, for example, containing 0.1 mg to 500 mg of active ingredient per unit dosage form.

The exact dosage and frequency of administration depends on the particular compound of formula (I) used, the particular condition being treated, the severity of the condition being treated, the age, weight and general physical condition of the particular patient as well as other medication the patient may be taking, as is well known to those skilled in the art. Furthermore, it is evident that said effective daily amount may be lowered or increased depending on the response of the treated patient and/or depending on the evaluation of the physician prescribing the compound of the instant invention. The effective daily amount ranges mentioned hereinabove are therefore only guidelines.

C. examples Example C. 1: Inhibition of retinoic acid (RA) metabolism MCF-7 human breast cancer cells were grown as stock cultures according to art-known protocols. One day before the experiment, RA is added to the stock cultures to stimulate RA-metabolism. At the start of the experiment, cell suspensions were incubated in a tissue culture medium containing 3H-RA as the substrat. Different concentrations of the test compound (dissolve in 1 % DMSO) were added to the incubation mixtures, and at the end of the incubation, the unmetabolized RA is separated from its polar metabolites.

The fraction containing the polar 3H-labelled metabolites was collecte and counted in a scintillation conter. For each experiment, a control and a blank incubation were run in parallel. Table 22 list the IC50 value (defined as the concentration in M needed to reduce the amount of metabolites to 50 % of the control). Table 22 Co. IC50 Co. IC50 Co. IC50 Co. IC50 Co. IC50 Co.

Example C. 2:"Vaginal Keratinization Test on Ovariectomized Rats" Ovariectomized rats were injecte subcutaneously with a sesame oil solution containing 100 Rg of estradiol undecylate in a volume of 0.1 ml per 100 g body weight and control animals were injecte with sesame oil. On day one, two and three, test <BR> <BR> animals were treated once daily with a per os dose of the test compound and control animals with the drug vehicle (PEG 200). One day after the last treatment, the animals were sacrifice and their vaginas were processed for histological evaluation according to the method described in J. Pharmacol. Exp. Ther. 261 (2), 773-779 (1992). A dose at which 50 % of the tested rats show complete suppression of the estradiol undecylate induced keratinization effects is defined as an active dose. Table 23 lists the lowest active dose (LAD in mg/kg) of the compound of formula (I) which were tested.
