Acetoxy substituted 1,1,2-triphenylbut-1-enes: estrogenic, antiestrogenic and mammary tumor inhibiting activity

Journal of Cancer Research and Clinical Oncology
M R Schneider


1,1,2-Triphenylbut-1-enes substituted with 3- or 4-acetoxy (OAc) groups on one, two, or three phenyl rings were tested for their estrogen receptor affinities, their estrogenic and antiestrogenic properties in the immature mouse, and their effect on the growth of the hormone-dependent MXT mammary tumor of the mouse. The 4-OAc-substituted compounds had a stronger uterotrophic potency than their 3-OAc-substituted analogs. A certain correlation between estrogenic properties and receptor affinities was demonstrable. Compounds with 3-OAc groups generally had antiestrogenic properties. By varying the aromatic substitution it was possible to obtain compounds ranging from strong estrogens to potent antiestrogens with almost no agonistic activity. The 4-OAc-substituted triphenylbut-1-enes had a better antitumor effect than the compounds with 3-OAc moieties. Thus, the tumor inhibiting activity correlates more with the estrogenic than with the antiestrogenic properties. The strong antiestrogens among these compounds did not show any significant antitumor effect. Further studies are necessary to solve the problem why strong antiestrogens do not, in contrast to ovariectomy, inhibit tumor growth.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.
