The primary goal of this review article is to increase the reader's knowledge and
understanding of problems associated with the radiopharmaceuticals commonly used in …

A price is paid for a beard and the presence of functional testes. Inheritance, ageing, and
other factors determine what the cost will be to the individual.(Hamilton 1948, p. 315) Many …

In order to investigate possible correlations between the uptake of 16α-([18 F] fluoro)-17β-
estradiol (18 F-ES) by 7, 12-dimethylbenz (a) anthracene (DMBA)-induced tumors in rats …

The design and development of radiolabelled steroid derivatives has been an important
area of research due to their wellknown value in breast cancer targeting. The estrogen …

We have prepared and studied six new analogs of 16α-fluoroestradiol (FES): 17α-and 17β-
ethynyl-FES (7 [FEES] and 7a), and the 11β-ethyl (8 and 8a) and 11β-methoxy (9 and 9a) …

Most efforts at developing steroid receptor-based imaging agents have, up to now, been
focused on the estrogen receptor (ER) in breast cancer. Success in this area has been very …

While pharmacology has traditionally been a discipline concerned with therapeutic drugs,
many parallels can be drawn between pharmacological considerations in the therapeutic …

We have prepared two estrogens labeled with carbon-11, 17α-[11C] methylestradiol and
11β-ethyl-17α-[11C] methylestradiol, at a specific activity of 300–1000 Ci/mmol (11.1–37 …

A series of three 125 I-labeled 17α-iodovinylestradiol derivatives previously demonstrated to
have a selectivity for estrogen receptor tissues in immature female rats were selected for …

Abstract The 21-tri-n-butylstannyl derivatives of (17α, 20E)-11α and β-methoxy-19-
norpregna-1, 3, 5 (10), 20-tetraene-3, 17β-diol were synthesized and characterized. These …
