The invention relates to novel oxime ethers of the formula I ##STR1## wherein R stands for a phenyl group which may be substituted by a halogen atom or by one or more C.sub.1 -C.sub.4 alkoxy, hydroxyl, nitro or di(C.sub.1 -C.sub.3 alkyl)amino groups, R.sup.1 and R.sup.2 denote each a hydrogen atom or together a valence bond, A denotes a C.sub.2 -C.sub.4 straight or branched-chain alkylene group, N denotes an integer from 3 to 10, and R.sup.3 and R.sup.4 denote a hydrogen atom or a C.sub.1 -C.sub.4 alkyl group, furthermore to acid addition salts and quaternary ammonium salts thereof. These new compounds are biologically active, and possess primarily local analgesic, spasmolytic, nicotine-lethality inhibiting, tetrabenazine-antagonistic and tetra-cor-spasm inhibiting effects.
该发明涉及公式I的新型肟醚化合物
其中R代表苯基,可以被卤原子或一个或多个C1-C4烷氧基,羟基,硝基或二(C1-C3烷基)氨基取代,R1和R2分别表示氢原子或一起表示一个价键,A表示C2-C4直链或支链烷基基团,N表示一个从3到10的整数,R3和R4表示氢原子或C1-C4烷基基团,此外还涉及其酸盐和季铵盐。这些新化合物具有生物活性,主要具有局部镇痛、解痉、抑制尼古丁致死、对四苯嗪的拮抗和对四氢-冠状痉挛的抑制作用。
