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 (mGluR_2/3).

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]^[10] which has led to research into LY-379,268 and similar compounds as antipsychotic drugs for the treatment of schizophrenia in animals.^[11]^[12]

There are inconsistent findings about an additional activity as a dopamine D2 receptor partial agonist.^[13]^[14]
