The present invention relates to new naphthyl derivatives of general formula ##STR1## wherein N represents the number 1 or 2, A represents a --CH.sub.2 --, --CO--, --CH.sub.2 CH.sub.2 --, --CH.dbd.CH--, ##STR2## while the atom marked with an x is linked to the phenyl nucleus, E represents a straight chained alkylene group optionally substituted by an alkyl group, G represents a straight chained alkylene group optionally substituted by an alkyl group, L represents a bond or an oxygen atom, if G represents a straight chained alkylene group with 2 to 5 carbon atoms optionally substituted by an alkyl group, R.sub.1 and R.sub.2, which may be identical or different, represent alkyl or alkoxy groups or R.sub.1 and R.sub.2 together represent an alkylenedioxy group, R.sub.3 represents a hydrogen atom, or an alkyl or an allyl group, R.sub.4, R.sub.5 and R.sub.6, which may be identical or different, represent hydrogen atoms, alkyl or alkoxy groups, the enantiomers and the acid addition salts thereof, which have valuable pharmacological properties, particularly a heart rate lowering activity. The new compounds may be prepared using methods known per se.
本发明涉及一种新的萘基衍生物,其一般式为##STR1##其中N代表数字1或2,A代表--CH.sub.2 --,--CO--,--CH.sub.2 CH.sub.2 --,--CH.dbd.CH--,##STR2##而带有x标记的原子连接到苯环,E代表可选地被烷基取代的直链烷基,G代表可选地被烷基取代的直链烷基,L代表键或氧原子,如果G代表具有2至5个碳原子的可选地被烷基取代的直链烷基,则R.sub.1和R.sub.2,可以相同或不同,代表烷基或烷氧基,或R.sub.1和R.sub.2一起代表烷二醚基,R.sub.3代表氢原子,或烷基或烯丙基,R.sub.4,R.sub.5和R.sub.6可以相同或不同,代表氢原子,烷基或烷氧基,其对手异构体和酸加成盐具有有价值的药理特性,特别是心率降低活性。新化合物可以使用已知的方法制备。
