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 effects of the new compounds exerted on
hormone-dependent twnours were tested b~ the method of
P. GriswoLd et aL. CCancer Research 26, 2L69 (L966)~
on mammary cancer induced by 7,L2-dimethyl-benz(a)~
anthracene (DMBA). 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~
