Abstract: The angiotensin II type 1 receptor (AT1R) has been recently crystallized. A new era has emerged
for the structure-based rational drug design and the synthesis of novel AT1R antagonists. In this critical review,
the X-ray crystallographic data of commercially available AT1R antagonists in free form are analyzed
and compared with the conformational analysis results obtained using a combination of NMR spectroscopy
and Molecular Modeling. The same AT1R antagonists are docked and compared in terms of their interactions
in their binding site using homology models and the crystallized AT1R receptor. Various aspects derived from
these comparisons regarding rational drug design are outlined.
