New compounds of the general formula (I) ##SPC1## and salts thereof were prepared by reacting a compound of the general formula (II) ##SPC2## with a compound of the general formula (III) or (IV) ##EQU1## and optionally saturating the --C=N-- bond. In the above formulae R.sup.1 and R.sup.2 are always the same and represent a C.sub.1-4 alkyl group, R.sup.3 stands for hydrogen, R.sup.4 and R.sup.5 each represent hydrogen or a straight-chained or branched C.sub.1-16 alkyl group optionally having an unsubstituted or substituted phenyl, furyl or naphthyl substituent, wherein said substituted aryl groups may contain up to 3 alkyl, C.sub.1-3 alkoxy, benzyloxy, nitro, amino, lower alkylamino, di-lower alkylamino, methylenedioxy, alkylmercapto, alkylsulfonyl or halogen substituents, or R.sup.4 and R.sup.5 may form together with the adjacent carbon atom a C.sub.3-12 cycloalkyl or C.sub.3-12 cycloalkylidene group, one of the methylene ring members of which being optionally replaced by an imino, lower alkylimino, or phenyl-lower alkylimino group, and R.sup.6 and R.sup.7 may stand for hydrogen, or R.sup.6 and R.sup.7 may form together a valence bond, and The R.sup.8 groups may each represent hydrogen, lower alkyl or alkanoyl, or the two R.sup.8 groups may form together a lower alkylene or alkanoylene group. The compounds of the general formula (I) possess primarily gastric acid secretion inhibiting and central nervous activities, furthermore they exert favourable action on the development of certain microorganisms which can be utilized in therapy.
通式(I)的新化合物及其盐通过将通式(II)的化合物与通式(III)或(IV)的化合物反应,并选择性饱和-C = N-键而制备。在上述公式中,R1和R2始终相同,表示C1-4烷基,R3代表氢,R4和R5分别表示氢或直链或支链C1-16烷基,可选地具有未取代或取代的苯基,呋喃基或萘基取代基,其中所述取代芳基基团可含有多达3个烷基,C1-3烷氧基,苄氧基,硝基,氨基,较低的烷基氨基,二较低的烷基氨基,亚甲基二氧基,烷基硫醇基,烷基磺酰基或卤素取代基,或R4和R5可以与相邻的碳原子一起形成C3-12环烷基或C3-12环烷基亚甲基,其中其中的一个甲基环成员可以被亚胺基,较低的烷基亚胺基或苯基较低的烷基亚胺基取代,而R6和R7可以代表氢,或R6和R7可以一起形成一个价键,而R8基团可以代表氢,较低的烷基或烷酰基,或两个R8基团可以一起形成较低的烷基或烷酰基亚基。通式(I)的化合物主要具有抑制胃酸分泌和中枢神经活性,此外它们对某些可用于治疗的微生物的发展具有有利作用。
