NMDA receptor glycine site antagonists

I'm interested in blocking the glycine binding site on NMDA 
receptor-channels in an in vitro slice preparation (electrophysiology). 
RBI and Tocris sell HA-966 and the related L-689,560; are these compounds 
functional blockers of NMDA currents? I've also seen 
7-Cl-thio-kynurenalte and its derivative, 5,7-DCK used as glycine 
antagonists, but these drugs seem to have fallen out of favor in recent 
times; are HA-966 and L-689,560 better? And, finally, how good are 
ACEA1021 and ACEA1328 as glycine site antagonists? Are they considered to 
be the best available, and which company(ies) make and/or sell them?

Thanks for the help.
