title: Structure-activity relationship studies of xanthone and fluorenone-1,4-dihydropyridine-5-phosphonates.
abstract: A series of xanthone and fluorenone-1,4-dihydropyridine derivatives bearing a 5-phosphonate group were prepared. The compounds were evaluated for inotropic, chronotropic and calcium antagonistic properties. The insertion of a phosphonate group is detrimental for inotropic and calcium antagonistic activity but improves the potency and selectivity for chronotropism.
