Nuclear hormone receptors (NRs) are potential targets for thera-
peutic approaches to many clinical conditions, including cancer,
diabetes, and neurological diseases. The crystal structure of the
ligand binding domain of agonist-bound NRs enables the design of
compounds with agonist activity. However, with the exception of
the human estrogen receptor- , the lack of antagonist-bound
``inactive'' receptor structures hinders the rational design of re-
ceptor antagonists. In this study, we present a strategy for design-
ing such antagonists. We constructed a model of the inactive
conformation of human retinoic acid receptor- by using informa-
tion derived from antagonist-bound estrogen receptor- and ap-
