A. Bisi et al., SYNTHESIS AND PHARMACOLOGICAL PROFILE OF SOME CHLOROXANTHONE-1,4-DIHYDROPYRIDINE DERIVATIVES, Arzneimittel-Forschung, 46(9), 1996, pp. 848-851
A series of xanthone-1,4-dihydropyridine derivatives bearing a chlorin
e atom in the xanthone nucleus was prepared. The compounds were evalua
ted for inotropic, chronotropic and calcium antagonist properties. The
chlorine introduction in the xanthone moiety slightly affected affini
ty for cardiac vs. vascular tissues improving to some extent selectivi
ty.
