摘要:
Compounds represented by general formula (I), pharmaceutically acceptable salts thereof, and hydrates of the same; and medicinal compositions such as endothelin receptor antagonists, remedies for peripheral circulatory insufficiency or macrophage foaming inhibitors containing these compounds. In said formula (I), R?1, R2, R3 and R4¿ independently represent each hydrogen, optionally substituted alkyl, hydroxy, optionally substituted alkoxy, etc.; R5 represents optionally substituted alkyl, optionally substituted aryl, optionally substituted heterocycle, etc.; R6 represents hydrogen, optionally substituted alkyl, etc.; R7 represents hydrogen, optionally substituted alkyl, optionally substituted alkoxy, optionally substituted aryl, optionally substituted heterocycle, etc.; A represents S or O; and the broken line means the presence or absence of a bond.
摘要:
A process for producing a compound represented by formula (II) (wherein R?1, R2, R3, and R4¿ each independently represents hydrogen, alkyl, alkoxy, etc.; R5 represents alkyl or alkoxyalkyl; A represents O or S; Ar represents aryl, etc.; * indicates the position of an asymmetric carbon atom and that the compound is the (R) or (S) isomer; and Q represents an optically active reagent), characterized by isolating the target compound as crystals from a solution or suspension containing a compound represented by formula (II) (wherein * indicates the position of an asymmetric carbon atom and that the compound is the (R) or (S) isomer or is a mixture of both, and the other symbols have the same meanings as the above).
摘要:
A process for the preparation of compound (I'): which is characterized by reacting in a solvent a compound of the general formula (III): (wherein X is halogeno) with p-tolylacetylene, a cuprous salt, a catalyst, and a base, and then treating the resulting reaction mixture with an acid.
摘要:
A process for producing a compound represented by formula (I) which comprises reacting a compound represented by formula (V) with a compound represented by formula (VI) in the presence of a base; a process for producing a compound represented by formula (II) which comprises causing a halogenating agent to act on the compound represented by formula (I); a process for producing a compound represented by formula (IV) which comprises reacting the compound represented by formula (II) with a compound represented by formula (III); and the compound represented by formula (I), wherein Alk represents branched alkyl; Hal1 and Hal2 each represents halogeno; R?1 and R2¿ each independently represents halogeno, alkyl, alkoxy, nitro, and cyano; R?3 and R5¿ each represents hydrogen or an organic residue; and R4 represents an organic residue.

摘要:
A compound represented by general formula (I) or a pharmaceutically acceptable salt thereof, having a strong affinity for gastrin receptors and/or CCK-B receptors but not for CCK-A receptors and hence being useful for curing diseases related to gastrin receptors and/or CCK-B receptors without inducing side effect related to CCK-A receptors, wherein R1 represents hydrogen or lower alkyl; R2 represents lower alkoxy, lower alkylamino, lower cycloalkyl, optionally substituted phenyl or optionally substituted heterocycle; R3 represents optionally substituted phenyl; and R4 represents optionally substituted phenyl, optionally substituted cycloalkyl, optionally substituted alkyl or optionally substituted heterocycle.
