Synthesis and biological evaluation of a novel c-Myc inhibitor against colorectal cancer via blocking c-Myc/Max heterodimerization and disturbing its DNA binding
A block copolymer comprising two or more of blocks of the following formula (1), wherein at least two of a plurality of m's present in the copolymer represent a number of 5 or more, Ar's in adjacent two blocks in the copolymer are mutually different, and the copolymer has two Ar's when composed of 2 blocks of the formula (1), has two or more Ar's when composed of 3 blocks of the formula (1) and has four or more Ar's when composed of 4 or more blocks of the formula (1):
(in the formula (1), Ar represents a conjugative divalent group and represents the same divalent group in an identical block, and m represents a number of 1 or more showing the number average polymerization degree of Ar present in one block.).

Copper(II)-catalyzed boronic acid promoted chemoselective N-arylation of unprotected aminophenols has been developed. Selective N-arylation of 3-aminophenol is achieved with a Cu(OAc)2/AgOAc combination in MeOH at rt, whereas the chemoselective N-arylated products of 4-aminophenol can be obtained with a Cu(OAc)2/Cs2CO3 system and benzoic acid as an additive. These ligand-free conditions and “open-flask”
