The present invention provides a modifier for aromatic polyesters which enhances the melt fluidity of aromatic polyesters without a significant decrease in the heat resistance of the aromatic polyesters, and an aromatic polyester resin composition including the modifier for aromatic polyesters. The present invention relates to a modifier for aromatic polyesters comprising polyhydric phenol residues and residues of aromatic polycarboxylic acid, acid halide or acid anhydride thereof, and the modifier comprises a material having a structure composed of a first residue selected from the group consisting of divalent residues represented by Formula (I): —Ar—W

A newclass of antitumor agents, having structural analogy to amonafide, but differing by the addition of a fourth ring in the nucleus, was synthesized conveniently from anthracene. Compounds with a variety of substituents, containing a basic nitrogen atom and located on the imide nitrogen, were prepared. Thirteen of 19 new compounds had greater growth inhibitory potency than amonafide in a panel of
