3,3''-((2-Chlorophenyl)methylene)bis(4-hydroxy-2H-chromen-2-one)

Description

3,3'-((2-Chlorophenyl)methylene)bis(4-hydroxy-2H-chromen-2-one) is a non-nucleotide inhibitor of ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1; K_i = 50 μM).^1,2 It also inhibits urease (IC₅₀ = 84.53 μM for the Jack bean enzyme).³
