• Preparation of 17α-iodoethynylandrosta- and 17α-(2-iodoethenyl) androsta-4,6-dien-17β-ol-3-ones as active site-directed photoaffinity ligands for androgen-binding proteins
  作者：Pablo J. Diaz Cruz、N.Scott Mason、Benjamin J. Danzo、Howard E. Smith

  日期：1992.11

  Unsaturated analogues of androst-4-en-17 beta-ol-3-one, each with a 17 alpha-iodoethynyl or 17 alpha-(2-iodoethenyl) substituent, were prepared, and their relative binding affinities (RBAs) for androgen-binding protein (ABP) were compared with those of 5 alpha-androstan-17 beta-ol-3-one, androst-4-en-17 beta-ol-3-one, androsta-4,6-dien-17 beta-ol-3-one, and androsta-1,4,6-trien-17 beta-ol-3-one. These binding studies indicate that the iodine[125I] analogues of 17 alpha-iodoethynyl and 17 alpha-[(E)-2-iodoethenyl] derivatives of androsta-4,6-dien-17 beta-ol-3-one and androsta-1,4,6-trien-17 beta-ol-3-one will have RBAs at least twice as great as that of 5 alpha-androstan-17 beta-ol-3-one. They can be prepared from 17 alpha-ethynylandrosta-4-en-17 beta-ol-3-one, the final synthetic step using N-[125I]iodosuccinimide, and are potential radioiodinated, active site-directed photoaffinity ligands for ABP and testosterone-binding globulin.
