  Exploration of N-phosphonoalkyl-, N-phosphonoalkenyl-, and N-(phosphonoalkyl)phenyl-spaced .alpha.-amino acids as competitive N-methyl-D-aspartic acid antagonists

  摘要：

  A series of N-substituted alpha-amino acids containing terminal phosphonic acid groups has been synthesized as potential N-methyl-D-aspartate (NMDA) receptor antagonists. NMDA receptor affinity was determined by displacement of a known ligand ([H-3]CPP) from crude rat brain synaptic membranes; an antagonist action was demonstrated by the inhibition of glutamate-induced accumulation of [Ca-45(2+)] in cultured rat cortical neurons. Receptor affinity was significantly correlated with antagonist activity (Figure 1). Moderate affinity (IC50 = 1-2-mu-M) was retained for analogues (31 and 32, Table 1; and 59 and 66, Table II) with reduced flexibility in their phosphonate side chains and is consistent with entropy playing a role in determining receptor affinity. Modeling studies suggest a folded conformation that brings the distal phosphonic acid group into close proximity with the alpha-carboxylate is required for binding. Each of the active analogues possess entropy-limiting features (double bonds, phenyl rings) in their side chains that allows the superposition of their key NH2, alpha-COOH, and distal PO3H2 groups with those of known competitive antagonists. Affinity decreased for analogues with alpha-carbon substitution, presumably because the alpha-substituent inhibits the folding of these structures into a bioactive conformation and occupies receptor-excluded volume. A complete description of the NMDA antagonist pharmacophore model is provided in a companion paper. 1

  N-substituted .alpha.-amino acids and derivatives thereof are described, as well as methods for the preparation and pharmaceutical composition of same, which are useful in selectively blocking the N-methyl-D-aspartate (NMDA) excitatory amino acid receptors in mammals and also are useful in treating cerebrovascular disorders such as cerebral ischemia or cerebral infarction resulting from thromboembolic or hemorrhagic stroke, cerebral vasospasm, hypoglycemia, cardiac arrest, status epilepticus and cerebral trauma as well as for treating schizophrenia, epilepsy, neurodegenerative disorders, Alzheimer's disease or Huntington's disease and also additionally useful as anesthetics in surgical procedures where a finite risk of cerebrovascular damage exists.
