Abstract: This invention relates to the use of an .alpha.,.alpha.'-iminobis(methylene)bis[2-chromanmethanol] derivative for the manufacture of a medicament for the therapeutic or prophylactic treatment of humans suffering from or prone to degenerative diseases and conditions of the vascular and nervous system which are associated with oxidative stress.

Abstract: The present invention provides novel compounds of formula ##STR1## the N-oxides, the stereochemically isomeric forms thereof, and the pharmaceutically acceptable acid addition salts thereof, wherein A and B taken together form a bivalent radical of formula:--N.dbd.CH-- (a), --CH.dbd.N-- (b), --CH.sub.2 --CH.sub.2 -- (c), --CH.dbd.CH-- (d), --C(.dbd.O)--CH.sub.2 -- (e), --CH.sub.2 --C(.dbd.O)-- (f); R.sup.1 is hydrogen, C.sub.1-6 alkyl, or halo; R.sup.2 is hydrogen or halo; R.sup.3 is hydrogen; C.sub.1-8 alkyl; C.sub.3-6 cycloalkyl or C.sub.1-8 alkyl substituted with hydroxy, oxo, C.sub.3-6 cycloalkyl or aryl. Het is five- or six-membered optionally substituted heterocyclic ring. The use as a medicine, especially as a lipid lowering agent is disclosed as well as pharmaceutical compositions and processes for preparing compounds and compositions.

Abstract: The present invention concerns novel compounds of formula (I). ##STR1## wherein R.sup.1 is C.sub.1-10 alkyl, C.sub.3-7 cycloalkyl or C.sub.1-6 alkyl substituted with C.sub.3-7 cycloalkyl; R.sup.2 is hydrogen or C.sub.1-6 alkyl; Alk represents C.sub.1-3 alkanediyl; --A-- represents a bivalent radical of formula --CH.dbd.CH--N.dbd.CH-- (a), --N.dbd.CH--N.dbd.CH-- (b), --CH.dbd.N--N.dbd.CH-- (c), --CH.dbd.CH--CH.dbd.N-- (d); in said bivalent radicals a hydrogen atom may be replaced by C.sub.1-6 alkyl; and Ar is unsubstituted phenyl; phenyl substituted with up to two substituents selected from halo, C.sub.1-6 alkyl or C.sub.1-6 alkyloxy; unsubstituted naphthyl; or naphthyl substituted with up to two substituents selected from halo, C.sub.1-6 alkyl or C.sub.1-6 alkyloxy; the stereochemically isomeric forms thereof, and the pharmaceutically acceptable acid addition salts thereof.
