synthesis, using parallel solution-phase methods, of a library of 104 potential inhibitors of PTPases. The library members are based on the bis(aryl alpha-ketocarboxylic acid) motif that incorporates a carboxylic acid on the central benzene linker. This carboxylic acid was coupled with a variety of different aromatic amines through an amide linkage. The aromatic component of the resulting amides is designed

To provide a novel polyhydroxyalkanoate having a reactive functional group in a molecule and a method of producing the same; and a novel polyhydroxyalkanoate having a new function obtained by chemically modifying the polyhydroxyalkanoate having a reactive functional group and a method of producing the same. By utilizing a vinyl group of a polyhydroxyalkanoate containing a unit having the vinyl group at a side chain thereof, a polyhydroxyalkanoate containing units having a carboxyl group, an amide group, and a sulfonic group in a molecule is induced.
