This invention relates to pharmaceutical compositions comprising compounds of formula
or a pharmaceutically acceptable saltthereofwherein-B-B1- represents a chain of formula
or
or
R represents an optionally substituted aryl or heteroaryl radical,
R', R2, R3 and R4 independently represent hydrogen, or a defined substituent or any adjacent pair of R', R2, R3 and R4 together with the carbon atoms to which they are attached complete a five or six membered saturated or unsaturated carbocyclic or heterocyclic ring, said ring being optionally substituted by a defined substituentand said heterocyclic ring having at least one heteroatom selected from oxygen, nitrogen and sulphur;
R5 and R6 independently represent hydrogen or lower alkyl; n and m independently represent 0 or 1, providing that when -B-B'- has formula la, n is 1 and m is O then R is heteroaryl, the term "heteroaryl" means a monovalent aromatic heterocyclic group in which the ring heteroatom or atoms is/are selected from oxygen, nitrogen and sulphur; and a pharmaceutically acceptable carrier which have anti-uicer and/or anti-secretory activity. Novel compounds of formula I are also disclosed together with processes for preparing them.
本发明涉及药物组合物,该药物组合物包含式
或其药学上可接受的盐,其中 B-B1- 代表式链
或
或
R 代表任选取代的芳基或杂芳基、
R'、R2、R3 和 R4 独立地代表氢,或一个定义的取代基,或任何相邻的一对 R'、R2、R3 和 R4 与它们所连接的碳原子一起组成一个五或六个成员的饱和或不饱和碳环或杂环,所述环可任选被一个定义的取代基取代,所述杂环具有至少一个选自氧、氮和硫的杂原子;
R5和R6独立地代表氢或低级烷基;n和m独立地代表0或1,条件是当-B-B'-具有式la,n为1,m为O时,R为杂芳基,术语 "杂芳基 "指环杂原子选自氧、氮和硫的一价芳香杂环基团;以及具有抗尿酸和/或抗分泌活性的药学上可接受的载体。此外,还公开了式 I 的新型化合物及其制备方法。
