Comparison of 3D structures and AT(1) binding properties of pyrazolidine-3,5-diones and tetrahydropyridazine-3,6-diones with parent antihypertensive drug irbesartan.


A new series of nonpeptide AT(1) receptor antagonists were recently developed, based on the structure of irbesartan (Le Bourdonnec et al. J. Med. Chem. 2000, 43, 2685-2697). The lead compound 1 displayed high selectivity for the AT(1) receptor subtype but lower binding affinity than irbesartan. As expected from molecular modeling studies, extension of the… (More)
