Abstract
The present invention provides compounds having H.sub.3 histamine receptor antagonist activity of formula (1.0) wherein R.sub.2 is a hydrogen or a methyl or ethyl group; R.sub.3 is a hydrogen or a methyl or ethyl group; n is 0, 1, 2, 3, 4, 5, or 6; and R.sub.1 is selected from the group consisting of (a) C.sub.3 to C.sub.8 cycloalkyl; (b) phenyl or substituted pneyly; (c) alkyl; (d) heterocyclic; (e) decahydronaphthalene; and (f) octahydroindene; with the proviso that when X is H, A can be --CH.sub.2 CH.sub.2, --COCH.sub.2 --CON(CH.sub.3)--, --CH.dbd.CH--, .alpha., --CH.sub.2 --NH--, --CH.sub.3 --N(CH.sub.3)--, --CH(OH)CH.sub.2 --, --NH--CH.sub.2 --, --N(CH.sub.3)--CH.sub.2 --, --CH.sub.2 O--, --CH.sub.2 S--, and --NHCOO--; when X is NH.sub.2, HN(CH.sub.3), N(CH.sub.3).sub.2, OH, OCH.sub.3, CH.sub.3, SH and SCH.sub.3 ; A can be --NHCO--, --N(CH.sub.3)--CO--, --NHCH.sub.2 --, --N(CH.sub.3)--CH.sub.2 --, --CH.dbd.XH--, --COCH.sub.2 --, --CH.sub.2 CH.sub.2 --, --CH( )H)CH.sub.2 --, or .beta.; and when R.sub.1 and X taken together denote a 5,6 or 6,6 saturated bicyclic ring structure, X can be NH, O, or S. The pharmaceutically acceptable salts, hydrates, and individual stereoisomers of…
