NMDA Brain Receptor (IMAGE) Cold Spring Harbor Laboratory Caption After seeing exactly how the chemical compound UBP791 fits into a subunit (D1/D2) of an NMDA brain receptor (as visualized above by Furukawa's lab) chemists can now work on designing a version of the compound that fits into that subunit and no others. In this way, they work towards a level of chemical specificity ideal for experiments and drug design.
