There are described compounds of formula I, ##STR1## in which A is a benzene or heterocyclic ring, y is 0 or 1, L is a group containing 1 or 2 carbon atoms, or is a single bond, R.sub.9 and R.sub.10 have a variety of significances, e.g. R.sub.10 may form part of a double bond with L, or the group --NR.sub.9 R.sub.10 forms a ring carrying substituents R.sub.1 and R.sub.8, or when L is a single bond --NR.sub.10 and R.sub.8 may form a ring carrying substituents R.sub.16 to R.sub.25, or the group --LNR.sub.9 R.sub.10 forms a heterocyclic ring carrying substituents R.sub.26 to R.sub.33, R.sub.1 to R.sub.8 and R.sub.16 to R.sub.33 have a variety of significances n is 0, 1 or 2, x is 3, 4 or 5, X is S, O or NR.sub.15, R.sub.15 is hydrogen, --COR, --COOR or alkyl optionally substituted by --OCOR, and certain provisos. Processes for making the compounds and pharmaceutical formulations containing them, e.g. for the treatment of conditions involving excess gastric acid secretion, are also described.
本文描述了化合物I的公式,其中A是苯或杂环环,y为0或1,L是含有1或2个碳原子的基团,或者是一个单键,R.sub.9和R.sub.10具有各种意义,例如R.sub.10可以与L形成双键,或者--NR.sub.9 R.sub.10基团形成一个带有R.sub.1和R.sub.8取代基的环,当L是一个单键时,--NR.sub.10和R.sub.8可以形成一个带有R.sub.16到R.sub.25的取代基的环,或者--LNR.sub.9 R.sub.10基团形成一个带有R.sub.26到R.sub.33的取代基的杂环环,R.sub.1到R.sub.8和R.sub.16到R.sub.33具有各种意义,n为0、1或2,x为3、4或5,X为S、O或NR.sub.15,R.sub.15为氢、--COR、--COOR或烷基,可以选择地被--OCOR取代,以及某些条件。还描述了制备这些化合物和含有它们的制药配方,例如用于治疗涉及过多胃酸分泌的疾病。
