Maolanon, Alex R.,Risgaard, Rune,Wang, Shuang-Yan,Snoep, Yoran,Papangelis, Athanasios,Yi, Feng,Holley, David,Barslund, Anne F.,Svenstrup, Niels,Hansen, Kasper B.,Clausen, Rasmus P.

A series of analogues based on serine as lead structure were designed, and their agonist activities were evaluated at recombinant NMDA receptor subtypes (GluN1/2A-D) using two-electrode voltage-clamp (TEVC) electrophysiology. Pronounced variation in subunit-selectivity, potency, and agonist efficacy was observed in a manner that was dependent on the GluN2 subunit in the NMDA receptor. In particular, compounds 15a and 16a are potent GluN2C-specific superagonists at the GluN1 subunit with agonist efficacies of 398% and 308% compared to glycine. This study demonstrates that subunit-selectivity among glycine site NMDA receptor agonists can be achieved and suggests that glycine-site agonists can be developed as pharmacological tool compounds to study GluN2C-specific effects in NMDA receptor-mediated neurotransmission.

Qi, Xian Liang,Yang, Er Qun,Zhang, Jun Tao,Wang, Tao,Cao, Xiao Ping
, p. 661 - 664 (2012/07/03)
A facile and improved route for the synthesis of the orally active spiroindoline-based growth hormone secretagogue, MK-677 was described. The key step adopted the Fischer indole/reduction strategy. The preparation of the key intermediates N-protected piperidine carboxaldehyde 5 and the N-Boc-O-benzyl-d-serine (2) are also optimized.
