Nimodipine: Synthesis and metabolic pathway

Key step of the synthesis of the calcium antagonistic cerebral vasodilator (±) isopropyl-2-methoxyethyl 1,4-dihydro-2,6-dimethyl-4-(3-nitrophenyl)-3,5-pyridinedicarboxylate (Bay e 9736, nimodipine) is the cyclising Michael addition. A pharmacokinetic study with 14C-nimodipine in the rat revealed as major metabolites the dihydropyridines as well as the pyridines. A potential metabolic pathway is discussed involving ether cleavage and oxidation to the pyridine form as primary biotransformation steps. Reference metabolites were synthesized using 1,4-dihydropyridines with appropriate functionalities as precursors.
