Ys. Lai et M. Stamper, HETEROATOM EFFECT IN THE PKC INHIBITORY ACTIVITIES OF PERHYDROAZEPINEANALOGS OF BALANOL, Bioorganic & medicinal chemistry letters, 5(18), 1995, pp. 2147-2150
Analogs 2-5 of balanol (-)-1, a potent protein kinase C (PKC) inhibito
r, were prepared in which the perhydroazepine N atom was replaced with
O, S, or C. Compounds 2 and 3 are found to show enhanced isozyme sele
ctivity, despite the general trend of these analogs being less potent
PKC inhibitors relative to balanol.
