The oestrogenic (uterotropic) effect was determined according to the method of R. J. Dorfman [Endocrinology 55, 65 (1954)]. 24 Days old female rats were treated with single daily oral dosages of the test compounds. On the 4th day the animals were sacrificed, and their uterus was removed and weighed. The data characteristic of the oestrogenic (uterotropic) effects of some of the compounds according to the invention are listed in Table 2. Ethynyloestradiol, a highly effective oestrogenic substance, and Clomifen and Tamoxifen, two known antioestrogenic agents, were also tested and their activity data are also pre-sented.
The compounds listed in Table 2 possess generally weak oestrogenic properties, or, in the dosage range of 0.1 to 1.0 mg/kg, their activity is somewhat lower than that of Tamoxifen.
The dosage-activity curve oE Compound No. 1 is, however, some-what steeper than those of the other compounds. Thus, in the lower dosage range (0.01 to 3.0 mg/kg) applied, the oestrogenic effect of Compound No. 1 is even weaker than the weak agonistic effects of the antioestrogenic agents, whereas the maximum increase in uterine weight attainable at higher dose ranges (10 mg/kg) wi.th Compound No. 1 is higher than that attalnable by -the antloestrogenic agents.

The treatment was s-tarted when the weight of the twnor reached about ~00 mg, and the animaLs were trea-ted for 3 months with oraL dosages o~` 20 m~/kg of the active a~ent, administered three times a ~eek. The size of the tumors was measured as L0 descrihed by the abo~e authors as well as accordin~
to the method of V.C. Jordan et aL. CEurcp, J. Cancer L2, 419 (L976)~, with 3 caLiper gauge. The ~olume of the twnor was determined 'by the method of ~.riswoLd~
The anirnaLs were kept under ob~ervation for 2 addi-L~ tionaL months af-ter the termination of the treatment period, and the tumors were measured in this latter period as weLl.
A relati~e effectivity index was lntroduced to characterize the activities of the compounds tested~
