Hazard Information	Back Directory
[Description] Diethyl 1,4-dihydro-2,4,6-trimethyl-3,5-pyridinedicarboxylate (DDC) inhibits heme production by inhibiting ferrochelatase, the enzyme that catalyzes the addition of Fe²⁺ to protoporphyrin IX to create heme B. Chronic DDC administration induces Mallory-Denk body formation, a feature of alcoholic and non-alcoholic hepatitis, and reduces IL-12A methylation in mouse liver.
[Chemical Properties] almost white crystalline powder
[Uses] Diethyl 1,4-dihydro-2,4,6-trimethyl-3,5-pyridinedicarboxylate was used to induce Mallory-Denk body formation in mice in vivo.
[Definition] ChEBI: A dihydropyridine that is 2,4,6-trimethyl-1,4-dihydropyridine substituted by ethoxycarbonyl groups at positions 3 and 5.
[Biochem/physiol Actions] Diethyl 1,4-dihydro-2,4,6-trimethyl-3,5-pyridinedicarboxylate blocks the heme synthesis and prevents the induction of hepatic heme oxygenase-1 in mice.
[Purification Methods] Crystallise the ester from hot EtOH/water mixture. [Beilstein 22 H 147, 22 I 529, 22 II 100, 22 III/IV 1594.]
