Biphenylindanone A (BINA, LS-193,571) is a research agent which acts as a potent and selective positive allosteric modulator for the group II metabotropic glutamate receptor subtype mGluR2.

In animal studies it showed anxiolytic and antipsychotic effects,[1] and blocked the effects produced by the hallucinogenic drug DOB. BINA and other selective mGluR2 positive modulators have therefore been suggested as a novel class of drugs for the treatment of schizophrenia which may have superior properties to traditional antipsychotic drugs.[2]

BINA decreases cocaine self-administration in rats, with no effect on food self-administration, and is in regard to this discrimination superior to the mGluR2/3 agonist LY-379,268[3]
