title: Synthesis and preliminary biological evaluation of 4,6-disubstituted 3-cyanopyridin-2(1H)-ones, a new class of calcium entry blockers.
abstract: The preparation of 3-cyano-4,6-diaryl-pyridin-2(1H)-ones 4a-h, calcium entry blockers related to diltiazem, is described starting from 1,3-diaryl-2-propen-1-ones 5. On preliminary pharmacological tests all compounds are active and some of them show calcium antagonistic activity superior or comparable to diltiazem.
