4-(4-Chlorophenyl)-4-piperidinol (CPPO) is one of haloperidol metabolite. Neurotoxicity studies in frogs, which have been used to detect N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) action, showed that CPPO did not mimic the neurotoxicity of MPTP but caused a delayed and persistent freezing action in Rana pipiens frogs. It is proposed that this action may contribute to some of the delayed side-effects associated with haloperidol therapy.
Hordenine is a natural Phenethylamine compound that occurs in a number of different plants, but especially barley grass. It is structurally similar to the amino acid Tyramine. It antagonized D2-mediated beta-arrestin recruitment indicating functional selectivity. Hordenine inhibited melanogenesis by suppressing cAMP production, which is involved in the expression of melanogenesis-related proteins. Hordenine may be an effective inhibitor of hyperpigmentation. Hordenine is an indirectly acting adrenergic drug. It liberates norepinephrine from stores. In isolated organs and those structures with reduced epinephrine contents, the hordenine-effect is only very poor. Experiments in intact animals (rats, dogs) show that hordenine has a positive inotropic effect upon the heart, increases systolic and diastolic blood pressure, peripheral blood flow volume, inhibits gut movements but has no effect upon the psychomotorical behavior of mice. Hordenine is considered to be generally very safe and well-tolerated in healthy adults. Hordenine is a nootropic compound that works equally well for cognitive enhancement and athletic performance.
Oroxylin A is a flavonoid compound, one of the main components extracted from Scutellariae radix. It possess a broad spectrum of pharmacological effects, especially anti-cancer, anti-inflammatory and neuroprotective activity. Oroxylin A inactivated HIF1α and reprogrammed fatty acid metabolism of HCT116 cells, decreasing intracellular fatty acid level and enhancing fatty acid oxidation. Oroxylin A improves attention-deficit hyperactivity disorder-like behaviors in spontaneously hypertensive rats via enhancement of dopamine neurotransmission and not modulation of GABA pathway as previously reported. Importantly, the present study indicates the potential therapeutic value of oroxylin A in the treatment of attention-deficit hyperactivity disorder. Both in vitro and in vivo study showed that oroxylin A possesses low toxicity, but the field was just limited in cancer research.
Canadine (tetrahydroberberine,THB) is an isoquinoline alkaloid (5,8,13,13a-tetrahydro-9,10-dimethoxy-6H-benzo[g]-1,3-benzodioxolo[5,6-a]quinolizine) from Corydalis tuber, it has micromolar affinity for dopamine D(2) (pK(i) = 6.08) and 5-HT(1A) (pK(i) = 5.38) receptors but moderate to no affinity for other relevant serotonin receptors (i.e., 5-HT(1B), 5-HT(1D), 5-HT(3), and 5-HT(4). Canadine enhances gastrointestinal motor function. THB, with D(2) receptor antagonist and 5-HT(1A) receptor agonist properties, has significant potential as a therapeutic for treatment of functional dyspepsia. THB is a potent inhibitor of platelet aggregation in vitro and in vivo and is a promising antithrombotic drug.
Alpha-ergocryptine is a component of the ergotoxine complex; it is the main ergot alkaloid of Japanese & South American wid grasses. Alpha-ergocryptine is an agonist at the D2 dopamine receptor. Alpha-ergocryptine effectively decreases intraocular pressure in the alpha-chymotrypsin-induced model of ocular hypertension.

P-88-8991, (-)- is a metabolite of Iloperidone. It has functional affinity for noradrenergic, dopaminergic and serotoninergic receptors. Humans produce only one enantiomer stereospecifically following administration of Iloperidone. Preclinical studies revealed that P-88-8991, (-)- might be useful for the treatment of psychotic disorders such as schizophrenia and bipolar disorders.
