Wh. Chu et al., THYROTROPIN-RELEASING-HORMONE ANALOGS - A BUILDING-BLOCK APPROACH TO THE CONSTRUCTION OF TETRACYCLIC PEPTIDOMIMETICS, Bioorganic & medicinal chemistry letters, 8(21), 1998, pp. 3093-3096
A building block based approach was used to synthesize a pair of tetra
cyclic peptidomimetics that constrain all but one of the rotational de
grees of freedom of the hypothalamic tripeptide hormone thyroliberin.
One of the analogs bound to the thyroliberin endocrine receptor (TRH-R
) with an affinity greater than that of an analog without constraints.
The tetracyclic peptidomimetics were found to be partial agonists for
the TRH-R receptor. (C) 1998 Elsevier Science Ltd. All rights reserve
