    摘要: An objective of the present invention is to provide novel compounds which have inhibitory activity against autophosphorylation of an FGF receptor family and, when orally or intraveneously administered, can suppress the growth of cancer cells. The compounds of the present invention are represented by formula (I) or a pharmaceutically acceptable salt or solvate thereof: wherein X represents CH or N; Z represents O or S; Q represents NR10, CR11R2, carbonyl, O, S(═O)m, wherein m is 0 to 2, or urea; R1 to R3 each independently represent H, OH, halogen, nitro, amino, alkyl, alkoxy or the like in which the alkyl and alkoxy groups are optionally substituted; R4 represents H; R5 to R8 each independently represent H, halogen, alkyl, or alkoxy; and R9 represents an optionally substituted carbocyclic or heterocyclic group.

    摘要: The present invention relates to a process for producing a 4-quinolone derivative, comprising allowing an o-aminoacetophenone derivative to react with a formic acid in an aprotic solvent in the presence of a suitable base, and adding a protic solvent to the reaction mixture. This is a simple process for producing 4-quinolone derivatives, applicable to large-scale commercial production.
