LY-379,268 is a drug that is used in neuroscience research, which acts as a potent and selective agonist for the group II metabotropic glutamate receptors (mGluR2/3).

It is derived from the older mGluR group II agonist eglumegad,[1] and led on to the development of the more potent compound LY-404,039,[2] but is still widely used in research itself. LY-379,268 has sedative, neuroprotective, anti-addictive and anticonvulsant effects in animals,[3][4][5] and blocks the effects of PCP and DOI,[6][7][8][9] which has led to research into LY-379,268 and similar compounds as antipsychotic drugs for the treatment of schizophrenia.[10][11]

There are inconsistent findings about an additional activity as a dopamine D2 receptor partial agonist.[12][13]
