SummaryThe antineoplastic activity of 4-chloro-2-(2,6-dichloro-4-hydroxyphenyl)-1-ethyl-6-hydroxyindole (D 15413) was determined in several estrogen-dependent mammary tumor models. The growth of DMBA-induced rat mammary carcinomas was inhibited by doses ranging from 2 to 18 mg/kg. A dose of 6×12 mg/kg per week p.o. reduced the tumor area by 82% (control+192%). D 15413 was also active against MNU-induced rat mammary tumors and transplanted MXT tumors of the mouse. In vitro, the growth of…

Synthesis and Estrogen Receptor Affinity of 2,3‐Diarylindoles

2‐Phenylindoles with aromatic substituents at C‐3 and hydroxy functions at the aromatic rings were synthesized and tested for their binding affinity for the calf uterine estrogen receptor and the highest binding affinity was found with 3‐(4‐hydroxyphenyl)‐2‐phenylindole (3b).



Antiestrogenic effects of LY 117018 in MCF-7 cells.

It is concluded that LY 117018 is a very effective antiestrogen devoid of any stimulatory effects among these parameters tested.

MXT mouse mammary tumour: Growth inhibition by tamoxifen or oestrogen administration

The data reported definitively demonstrate the efficacy of tamoxifen on hormone-sensitive mouse mammary tumours and that the antitumour potency of the drug is derived from its oestrogenic property.

Uterine bioassay of tamoxifen, trioxifene and a new estrogen antagonist (LY117018) in rats and mice.

Proliferative pattern of uterine cells from birth to adulthood in intact, neonatally castrated, and/or adrenalectomized mice, assayed by incorporation of [125I]iododeoxyuridine.

It is suggested that sex steroids secreted from both the ovaries and adrenals of neonatal and prepubertal mice play no significant role in the proliferation of uterine cells, and that a quiescent interval of cell proliferation occurs around day 20 after birth between the autonomous (days 0-15) and the ovary-dependent (after day 25) proliferation of mouse uterusine cells.

Estrophilin assays in breast cancer: Quantitative features and application to the mastectomy specimen

Present results indicate that predictions of response to endocrine therapy at time of recurrence can be based on the estrophilin assay of the primary lesion, and there is a general tendency toward decreased estrophILin content with time.

The problem of nonresponding estrogen receptor‐positive patients with advanced breast cancer

Patients with advanced breast cancer and low or poor concentration of estrogen receptors in tumor biopsies have little chance of responding to endocrine therapy and suggestions to overcome it are given.
