The interactions of phencyclidine (PCP) and related agonists with putative receptor blockers were studied on cerebellar Purkinje neurons using electrophysiological techniques. Depressions induced by PCP or dexoxadrol, a sigma receptor agonist, were markedly antagonized by the PCP receptor antagonist metaphit, which acylates PCP receptors via its isothiocyanate moiety. Conversely, the depressant effect of levoxadrol, the (-) isomer of dexoxadrol, was not affected by metaphit. Further evidence that metaphit's specific antagonism of dexoxadrol- and PCP-mediated depressions was derived from data showing that drugs which respectively acylate mu and delta opioid receptors, benzimidazole isothiocyanate and fentanyl isothiocyanate, do not antagonize the actions of either PCP or dexoxadrol. Moreover, tyramine, which like PCP acts as an indirect norepinephrine agonist, is not antagonized by metaphit. These observations support the concept that metaphit causes a pharmacologically specific and irreversible antagonism of the effects of both PCP and dexoxadrol in the cerebellum. ...
... Phencyclidine (PCP)-induced catalepsy in pigeons, which is a pharmacologically specific and stereoselective phenomenon, was used to study pharmacological consequences of the proposed covalent bonding of metaphit to PCP sites. Metaphit pretreatment increased the cataleptic effects induced by cumulative doses of PCP-type drugs (ie, PCP, ketamine and m-amino PCP) and of drugs that have PCP-like actions (i.e., dexoxadrol, LY 154716 and cyclazocine)...
The binding of [3H]phencyclidine (PCP) to receptors in rat brain cortex has been studied. Two receptors have been detected, a high affinity receptor site with a KD of 23.5 +/- 7.4 nM and a low affinity site with a KD of 7.6 +/- 1.8 microM. The binding of [3H]PCP to its receptors was pH and temperature dependent and was destroyed by heat-denaturation. The binding of [3H]PCP was inhibited by compounds which produce PCP-like behavioral effects including dexoxadrol, etoxadrol and ketamine as well as a novel series of benz(f)isoquinolines. The low affinity site was blocked by PCP, etoxadrol and (+)-SKF-10,047 but not morphine or leu-enkephalin, suggesting that it also represents a specific PCP site. Stereoselective displacement of PCP at the high affinity receptor was observed with the isomers of cyclazocine, cyclorphan, SKF-10,047 and dioxadrol (dexoxadrol and levoxadrol). Naloxone, 4,5,6,7-tetrahydroisoxazolo(S,4-C)pyridin-3-ol (THIP) hydrate and haloperidol inhibited binding poorly (Ki greater than 1 microM), suggesting that these compounds do not interact significantly with the high affinity PCP receptor in vivo. The affinity of ligands for the phencyclidine receptor was highly correlated (r = 0.714, P less than 0.01) with their potency to produce catalepsy in pigeons.
/SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Poisons A and B/
/SRP:/ Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if needed. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... .

(3)H-Dexoxadrol, a dissociative anesthetic, binds with high affinity to specific sites in rat brain (membrane binding and light microscopic autoradiography). Various phencyclidine analogues compete for (3)H-dexoxadrol sites in a slightly different manner than against (3)H-phencyclidine binding sites. As for (3)H-phencyclidine binding, (3)H-dexoxadrol binding sites are highly concentrated in brain regions such as the cortex and the hippocampus. However, other areas such as the hypothalamus are enriched only in (3)H-dexoxadrol binding sites. This suggests that (3)H-dexoxadrol binds to phencyclidine-related sites in certain brain regions but not in others. In the human forebrain, (3)H-dexoxadrol binding sites are distributed as in the rat brain and mainly found in the caudate, putamen and cortex.
