The present invention provides 2-furancarboxylic acid hydrazide compounds represented by General Formula (I) below, and prodrugs, physiologically acceptable salts, hydrates, solvates thereof, methods for producing them and pharmaceutical compositions containing them:
wherein A is a group represented by Formula (a) or the like:
(wherein either R
4
or R
5
represents cyano, nitro or the like, and the other represents a hydrogen atom or the like);
either R
1
or R
2
represents a group: -D-(X)m-R
6
or the like, and the other represents a group: -E-(Y)n-R
7
, hydrogen atom, aryl or the like;
R
3
is a hydrogen atom or the like; D and E independently represent aryl; X and Y independently represent O or the like;
R
6
and R
7
independently represent alkyl, aryl, arylalkyl or the like; and m and n are independently 0 or 1, provided that the aryl is optionally substituted. Such compounds exhibit a potent antagonistic activity on glucagon receptor and are of use as preventive and/or therapeutic agents for symptoms and diseases in which glucagon is involved.
本发明提供了由下列通式(I)表示的2-呋喃羧酸肼化合物,以及它们的前药、生理上可接受的盐、水合物、溶剂化物、制备方法和含有它们的制药组合物:其中A是由式(a)或类似式表示的基团:(其中R4或R5代表氰基、硝基或类似物,另一个代表氢原子或类似物);R1或R2代表基团:-D-(X)m-R6或类似物,另一个代表基团:-E-(Y)n-R7、氢原子、芳基或类似物;R3是氢原子或类似物;D和E独立地表示芳基;X和Y独立地表示O或类似物;R6和R7独立地表示烷基、芳基、芳基烷基或类似物;m和n独立地表示0或1,但芳基可选择性地被取代。这些化合物表现出强大的胰高血糖素受体拮抗活性,并且可用作预防和/或治疗胰高血糖素参与的症状和疾病的药物。
