GRN-529 is a research drug that was developed by Wyeth as a negative allosteric modulator of the metabotropic glutamate receptor 5 (mGluR5).^[1]

A study conducted by Pfizer found that GRN-529 reduced repetitive behaviors without sedation and partially increased sociability in mouse models of autism. ^[2]

Another study conducted by Pfizer found a therapeutically relevant effect in animal models of depression. It is theorized to work by reducing glutamate receptor hyperactivity.^[3]
