title: Amino-substituted heterocycles as isosteres of trans-cinnamides: design and synthesis of heterocyclic biaryl sulfides as potent antagonists of LFA-1/ICAM-1 binding.
abstract: 2-Amino-4-phenyl pyridine and, to a lesser extent, 4-amino-6-phenyl pyrimidine, were established as isosteres of trans-cinnamide moiety. Applying this isosterism to previously reported p-arylthio cinnamides resulted in the identification of 4-amino-6-(p-arylthio)phenyl-pyrimidines and 2-amino-4-(p-arylthio)phenyl-pyridines as potent antagonists of LFA-1/ICAM-1 binding.
