Pjd. Cruz et al., SYNTHESIS OF 25]IODOETHENYL]ANDROSTA-4,6-DIEN-17-BETA-OL-3-ONE, AN ACTIVE-SITE-DIRECTED PHOTOAFFINITY RADIOLABEL FOR ANDROGEN-BINDING PROTEINS, Journal of labelled compounds & radiopharmaceuticals, 33(9), 1993, pp. 853-862
The active-site-directed photoaffinity radiolabel for androgen-binding
proteins, 125]iodoethenyl]androsta-4,6-dien-17beta-ol-3-one, was prep
ared by reaction of yltin(IV)ethenyl]androsta-4,6-dien-17beta-ol-3-one
with carrier added sodium iodide-125 in the presence of hydrogen pero
xide and acetic acid. Purification by HPLC gave the radiolabeled stero
id in 52% radiochemical yield with a specific activity of 27 Ci/mmol a
nd 100% radiochemical purity.
