Fourphit, also known as 4-isothiocyanato-PCP, is an irreversible dopamine transporter (DAT) blocker and a reversible NMDA receptor antagonist. It blocks the binding of methylphenidate to the DAT in vitro, though apparently not in vivo. In any case, the drug reduces the stimulant-like effects of cocaine in animals, whilst producing mostly negligible behavioral effects itself. Fourphit is an acylating derivative of phencyclidine (PCP) and a positional isomer of metaphit (3-isothiocyanato-PCP).
