A novel series of N-(phenylalkyl)cinnamides related to N-(4- phenylbutyl)-3,4-dihydroxy-β-cyanocinnamide (6, an EGFR-K inhibitor with high antiproliferative activity) was synthesized and tested for antagonism at N-methyl-D-aspartate (NMDA) receptor subtypes. Potency and subunit selectivity were assayed by electrical recordings in Xenopus oocytes expressing three binary combinations of cloned rat NMDA receptor subunits: NR1A expressed in combination with either NR2A, NR2B, or NR2C. The N- (phenylalkyl)cinnamides are selective antagonists of NR1(A)/2B receptors. Assayed under steady-state conditions, N-(4-phenylbutyl)-4-hydroxycinnamide (16) has an IC50 value of 77 nM and > 1000-fold selectivity with respect to NR1(A)/2A and NR1(A)/2C receptors. Potency at α1 adrenergic receptors is low for the four cinnamides tested. Inhibition of NR1(A)/2B receptors does not correlate with EGFR and ErbB2/neu tyrosine kinase inhibitor activity. The N-(phenylalkyl)cinnamide series we describe provides a novel and structurally diverse framework for designing new NR2B-selective NMDA antagonists as potential CNS therapeutics.
