1,4-DPCA | Prolyl hydroxylase inhibitor

1,4-DPCA (331830-20-7) is a potent inhibitor of prolyl 4-hydroxylase (IC50=2-4 μM)1. Inhibits collagen deposition via inhibition of collagen proline hydroxylation2,3. Subcutaneous injection of a 1,4-DPCA containing hydrogel into Swiss Webster mice that do not show a regenerative phenotype increased expression of HIF1α over 5 days. Multiple injections led to regenerative wound healing after ear hole punch injury4.
