2-FURANCARBOXYLIC ACID HYDRAZIDES AND PHARMACEUTICAL COMPOSITIONS CONTAINING THE SAME

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 R4 or R5 represents cyano, nitro or the like, and the other represents a hydrogen atom or the like); either R1 or R2 represents a group: -D-(X)m-R6 or the like, and the other represents a group: -E-(Y)n-R7, hydrogen atom, aryl or the like; R3 is a hydrogen atom or the like; D and E independently represent aryl; X and Y independently represent 0 or the like; R6 and R7 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.

Mucochloric acid: A useful synthon for the selective synthesis of 4-aryl-3-chloro-2(5H)-furanones, (Z)-4-aryl-5-[1-(aryl)methylidenel-3-chloro-2(5H)-furanones and 3,4-diaryl-2(5H)-furanones

3,4-Dichloro-2(5H)-furanone, which has been prepared efficiently from mucochloric acid, has been transformed selectively into 4-aryl-3-chloro-2(5H)-furanones either by Suzukior Stille-type reactions. These monochloro derivatives have been used as precursors either to (Z)-4-aryl-5-[1-(aryl)methylidene]-3-chloro-2(5H)-furanones, including naturally occurring rubrolide M, or to unsymmetrical 3,4-diaryl-2(5H)-furanones. Some 2(5H)-furanone derivatives so prepared have been found to exhibit significant cytotoxic activity in vitro against the NCI three-cell-line panel, but limited cytotoxicity against the NCI human tumor 60 cell-line panel.

Total synthesis of rubrolide M and some of its unnatural congeners

Two protocols have been developed for the Pd-catalyzed regioselective synthesis of 4-aryl-3-chloro-2(5H)-furanones starting from 3,4-dichloro-2(5H)-furanone. These monochloro derivatives have then been used as precursors to (Z)-4-aryl-5-[1-(aryl)methylidene]-3-chloro-2(5H)-furanones including naturally-occurring rubrolide M.

A New Preparative Method for (E)-2,3-Diarylbut-2-enedials

Reaction of 1,2-diaryl-3,4-dibromocyclo-but-1-enes (4) with silver perchlorate in the presence of water gave (E)-2,3-diarylbut-2-enedials (5), which when treated with acid were converted into 2,3-diarylbut-2-en-4-olides (6).
