Synthesis of novel 2-substituted quinoline derivatives: antimicrobial, inotropic, and chronotropic activities.

abstract：:Several chloro- and iodo-lignanolides have been obtained by direct halogenation of aromatic rings from yatein and 4'-O-demethylyatein. They were assayed as antineoplastics, in order to check the influence in the activity of substitution in both aromatic rings. Although these compounds show a modest antineoplastic acti...
