Biochem/physiol Actions Biphenyl-indanone A (BINA) is a potent selective positive allosteric modulator for the group II metabotropic glutamate receptor subtype mGluR2. In animal studies BINA showed anxiolytic and antipsychotic effects, and blocked the effects produced by the hallucinogenic drug DOB. It decreased cocaine self-administration in rats, with no effect on food self-administration. In recombinant systems, BINA selectively potentiated the response of mGluR2 to glutamate with no effect on the glutamate response of other mGluR receptor subtypes tested. |
