Pharmacological research products.
I. Investigation of the activity of the products of the invention on hormone receptors.
Progestogenic receptor in the rabbit uterus.
Female rabbits that have not reached puberty, weighing about 1 kg, receive 25 g of estradiol by cutaneous method. 5 days after application, the animals are sacrificed, the uterus is removed, weighed and homogenized at 0 ° C, using Potter teflon glass in TS buffer solution (Tris 10 mM, sucrose 0.25 M, HCI pH 7.4 (1 g of tissue per 50 ml TS). Then the homogenization product is ultra centrifuged (W5000F X 90 min) with the thus obtained aliquot parts on the surface subjected to incubation at 0 ° C for a time t, at a constant concentration (T) of the tritiated product R (17,21-dimethyl 19-nor 4,9-pregnadien 3,20-dione) in the presence of increasing concentrations (0-2500 x 10 M) of either cold R, or cold progesterone, or cold test product. Then the concentration of bound tritiated R (B) is measured in each incubation product by the carbon-dextran absorption technique.
The glucocortinoid receptors of the retrosternal gland of the rat.
In rats of male Sprague-Dawley HOPS weighing 160-200 g, the adrenal glands are removed. Four to eight days after this removal, the animals are sacrificed, and the retrosternal glands are pressed and homogenized at 0 ° C in a buffer solution (tris 10 mM, sucrose 0.25 M, dithiothreitol 2 mM, HCI pH 7.4) using Potter PTFE glass (1 gtkani on 10 ml of TS). The homogenization product is then ultracentrifuged (10,500,000 / X 90 min) at 0 ° C. The aliquots thus obtained on the surface are incubated at 0 ° C for a time (t) with a constant concentration (T) of dexamethasone saturated with tritium in the presence of increasing concentrations (0-2500 10 M) or cold dexamethasone, or cold studied product. The concentration of bound tritiated (saturated) dexamethasone (B) is then measured in each incubation product by the carbon-dextran absorption technique.
The calculation of the relative affinity of communication (ARL) is the same for all receptors (Table 1).
Damn two curves: the percentage of bound tritiated hormone B / T depending on the logarithm
the concentration of cold hormone control and B / t depending on the logarithm of the concentration of the cold studied product. The direct equations of Iso are determined (B / T max + B / TMHH) / Z
B / T max is the percentage of tritiated hormone saturated for incubation of this hormone (tritiated) at a concentration (T).
B / Cmin is the percentage of tritiated hormone bound to incubate this tritiated hormone at a concentration (T) in the presence of a large excess of cold hormone (2500 10 M).
The intersection of the direct (BFU curves allows to estimate the concentrations of cold hormone control (CH) and cold test product (CX), which inhibit the 50% bond tritium hormone on the receptor.
The relative affinity of communication (ARL) of the product being studied is determined by the equation
ARL 100
(SH)
The test products, in particular the product of Example 4, show a very marked affinity for glucocorticoid and progestogen receptors.
Their results can be concluded that the products can exhibit agonistic or antagonistic activities of glucocorticoids and progestogens.
Ii. Anti-glucocorticoid activity.
The technique used is derived from a known method for the cells of the retrosternal gland of mice.
The cells of the retrosternal gland of rats, in which the adrenal glands were removed, are incubated at 37 ° C for 3 hours in a nutrient medium containing 5-10® M dexamethasone in the presence or absence of the test product at various concentrations. The uridine, saturated with tritium, is added and the incubation is continued for another 1 h. The incubation product is cooled, treated with 5% trichloroacetic acid solution, filtered on GF / A cotton paper, washed three times with 5% trichloroacetic acid solution. The radioactivity that is retained by the filter is determined.
Glucocorticoids, and in particular dexamethasone, cause a decrease in the incorporation of tritiated uridine. The products of examples 1-4 counteract this effect (Table 2). If the products studied are consumed alone, they do not show any effect like a glucocorticoid. The test products exhibit very marked anti-glucocorticoid activity, and at the same time they lack glucocorticoid activity. Ill, Abortion-causing activity in the rat. The day of Si pregnancy is determined by the presence of spermatozoa in a vaginal smear. On the day of pregnancy, a suspension product is introduced into carboxymethylcellulose. containing 0.5% tween. Animals are sacrificed 72 hours after treatment and the uterus is examined to determine the state of pregnancy. A complete abortion is established on all the animals of the troupe with the products of examples 1-4, administered in doses of 3 mg / kg. Results at a dose of 1 mg / kg for the product of Example 3: 100% abortion; mifepriston0% abortion. The toxicity of the target products of the method is absent, F o rmula and 3 o bre ee.
