[The influence of the ester function on the vasodilating activity of 1,4-dihydro-2,6-dimethyl-4-nitrophenyl-pyridine-3,5-dicarboxylates (author's transl)].
In the series of 1,4-dihydro-2,6-dimethyl-4-nitrophenyl-pyridine-3,5-dicarboxylates the vasodilating action (increase of O2-saturation in the coronary sinus of the dog) is found to be dependent on the position of the nitro function (ortho and meta superior to para) and on the nature of the ester group. One representative, niludipin (BAY a 7168, No. 17; bis(2-propoxyethyl)-1,4-dihydro-2,6-dimethyl-4-(3-nitrophenyl)-3,5-pyridinedicarboxylate) was selected for further pharmacological studies.
