Multi-target 1,4-dihydropyridines showing calcium channel blockade and antioxidant capacity for Alzheimer's disease therapy.

In this work we describe the synthesis, Ca+2 channel blockade capacity and antioxidant power of N3,N5-bis(2-(5-methoxy-1H-indol-3-yl)ethyl)-2,6-dimethyl-4-aryl-1,4-dihydropyridine-3,5-dicarboxamides 1-9, a number of multi-target small 1,4-dihydropyridines (DHP), designed by juxtaposition of melatonin and nimodipine. As a result, we have identified antioxidant DHP 7 (Ca2+ channel blockade: 55%, and 8.78 Trolox/Equivalents), the most balanced DHP analyzed here, for potential Alzheimer's disease therapy.
