explored to date. For that purpose, a series of new 2-amino-7-(bis(2-hydroxyethyl)amino)-4(phenyl)-4H-chromene-3-carbonitrile derivatives has been synthesized via piperidine catalyzed solvent-free protocol and evaluated for their antidiabetic activity as potential α-amylase inhibitors. The dose-dependent in vitro α-amylase inhibition study revealed that, most of these compounds exhibited significant antidiabetic

Herein are also provided a method for dyeing fiber materials, paper or leather by using said trisazo compound, and an ink containing said trisazo compound.
A dye-containing polarizing film comprising a polarizing film material and a metal-containing dye represented by the following formula (I):
wherein Me is a transition metal selected from copper, nickel, zinc and iron;
Z is hydrogen, lower alkyl, lower alkoxy, sulfo or amino which is unsubstituted or substituted;
Q is a 1-naphthol or 2-naphthol residue which is unsubstituted or substituted and has no or an additional phenylazo or naphthylazo group unsubstituted or substituted and in which a hydroxy group is adjacent to the azo group bonding to the benzene ring having Z and is linked with the transition metal denoted by Me to form the complex;
when Q is the naphthol residue having no additional azo group, then T is naphthyl which is unsubstituted or substituted; and
when Q is the naphthol residue having an additional azo group, the T is a phenyl or naphthyl group which is unsubstituted or substituted, which film exhibits comparable high polarizing activity with film using iodine and superior durability.
