VU0453595 is a highly selective, systemically active M1 positive allosteric modulator (PAM, EC50=2140 nM) for the research of schizophrenia[1][2].
Application of M1 PAM VU0453595 (3 μM) induces a transient increase in excitability of medium spiny neurons (MSNs)[3].
VU0453595 potentiates M1-mediated muscarinic long-term depression (mLTD)[1].VU0453595 (1-10 mg/kg; i.p.) reverses behavioral deficits induced by repeated phencyclidine (PCP) administration[1].
