Selective inhibition of prolyl 4-hydroxylases by bipyridinedicarboxylates.

ABSTRACT: Collagen is the most abundant protein in animals. A variety of indications are associated with the overproduction of collagen, including fibrotic diseases and cancer metastasis. The stability of collagen relies on the posttranslational modification of proline residues to form (2S,4R)-4-hydroxyproline. This modification is catalyzed by collagen prolyl 4-hydroxylases (CP4Hs), which are Fe(II)- and α-ketoglutarate (AKG)-dependent dioxygenases located in the lumen of the endoplasmic reticulum. Human CP4Hs are validated targets for treatment of both fibrotic diseases and metastatic breast cancer. Herein, we report on 2,2'-bipyridinedicarboxylates as inhibitors of a human CP4H. Although most 2,2'-bipyridinedicarboxylates are capable of inhibition via iron sequestration, the 4,5'- and 5,5'-dicarb
