HYDIA

HYDIA is a drug that is used in neuroscience research, which acts as a potent and selective antagonist for the group II metabotropic glutamate receptors (mGluR2/3). It has been useful in the mapping of the group II mGluR receptor proteins and their molecular modeling.[1] HYDIA is similar in structure to group II mGluR agonists such as eglumegad and LY-404,039, but the addition of the 3-hydroxy group reverses the activity to a competitive antagonist. Other derivatives such as the 3-benzyloxy ether are more potent antagonists than HYDIA itself.[2]
