title: Synthesis and pharmacological profile of some chloroxanthone-1, 4-dihydropyridine derivatives.
abstract: A series of xanthone-1,4-dihydrophyridine derivatives bearing a chlorine atom in the xanthone nucleus was prepared. The compounds were evaluated for inotropic, chronotropic and calcium antagonist properties. The chlorine introduction in the xanthone moiety slightly affected affinity for cardiac vs. vascular tissues improving to some extent selectivity.
