• Beschreibung

  Iloperidone is an atypical antipsychotic and adrenergic, dopamine, and serotonin (5-HT) receptor antagonist. It binds to several receptors, including the α₁-adrenergic receptor (α₁-AR), α₂-AR, and dopamine D₂ receptor (K_is = 0.31, 3, and 3.3 nM, respectively), as well as the 5-HT_1A, 5-HT_1D, 5-HT_2A, and 5-HT_2C receptors (K_is = 33, 15, 0.2, and 14 nM, respectively) in radioligand binding assays using human post-mortem brain tissue. Iloperidone also binds to human D₁, D₃, D₄, D₅, and rat 5-HT₂ receptors (K_is = 216, 7.1, 25, 319, and 3.1 nM, respectively, in CHO cells) and the histamine H₁ receptor (K_i = 12.3 nM in human post-mortem brain tissue). Iloperidone (1-3 mg/kg) prevents the reduction in prepulse inhibition induced by apomorphine , phencyclidine (PCP), and cirazoline in rats. It also increases the time rats spend in the open arms of the elevated plus maze and the number of social interactions when administered at a dose of 0.5 mg/kg. Formulations containing iloperidone have been used in the treatment of schizophrenia.

  Off-White Solid

• Verwenden

  Combined dopamine (D2) and serotonin (5HT2) receptor antagonist. Antipsychotic.

• Verwenden

  Iloperidone (Fanapt, Fanapta, Zomaril) is an atypical antipsychotic for the treatment of schizophrenia. Iloperidone is a monoamine directed towards acting upon and antagonizing specific neurotransmitters, particularly multiple dopamine and serotonin recep

• Definition

  ChEBI: A member of the class of piperidines that is the 4-acetyl-2-methoxyphenyl ether of 3-(piperidin-1-yl)propan-1-ol which is substituted at position 4 of the piperidine ring by a 6-fluoro-1,2-benzoxazol-3-yl group. A member of the group of second generation a tipsychotics (also known as an atypical antipsychotics), it is used for the treatment of schizophrenia.

• Allgemeine Beschreibung

  Iloperidone is an atypical antipsychotic administered for the treatment of schizophrenia. The drug is marketed under the trade names Fanapt and Fanapta. This Certified Spiking Solution^? is suitable for use in LC/MS or GC/MS applications including clinical toxicology, forensic testing, or pharmaceutical research.

• Biochem/physiol Actions

  Iloperidone is an atypical antipsychotic, a combined dopamine (D2) and serotonin (5HT2) receptor antagonist. Iloperidone targets a selective set of dopamine, serotonin and also norepinephrine receptor subtypes. Like similar atypical antipsychotics, Iloperidone has higher affinity for the 5-HT2A receptor (Ki < 10 nM) than for the D2 receptor (Ki = 10–100) nM). Iloperidone has high affinity for dopamine D3 (Ki < 10 nM) and lower affinity for other serotonin or dopamine subtypes. Unlike most atypical antipsychotics, Iloperidone also has high affinity for norepinephrine alpha1 receptors (Ki < 10 nM) which may contribute to the drug′s efficacy on mood and cognition.

• Clinical Use

  Acting as an antagonist on serotonin (5-HT2) and dopamine receptor subtypes, iloperidone is an antipsychotic indicated for the treatment of acute schizophrenia in adults. Based on its in vitro and in vivo binding properties against both serotonin and dopamine receptors, it is expected that iloperidone will show fewer extrapyramidal symptoms than currently marketed antipsychotics such as haloperidol and clozapine. The original discovery was made by Hoechst-Roussel Pharmaceuticals who passed the developing rights to Vanda Pharmaceuticals and subsequently Novartis for marketing in the U.S. and Canada. While this drug was originally approved in the U.S. in 2009, the marketing was only initiated in the U.S. in 2010.

• Synthese

  Although a number of syntheses are reported in the literature, the process enabled route from a key intermediate 98 is described in the scheme. The key intermediate 98 was synthesized from isonipecotic acid (94) in four steps. Formylation of isonipecotic acid (76% yield) followed by conversion of the acid to the acyl chloride gave 95 in 100% yield. Friedel-Crafts acylation of 1,3-difluorobenzene (96) with the acid chloride 95 provided ketone 97 in 32% yield. Treatment of ketone 97 with hydroxylamine hydrochloride in the presence of potassium hydroxide gave the corresponding oxime, which upon refluxing in 2-ethoxylethanol and water cyclized to piperidine benzisoxazole 98 with concomitant loss of the N-formyl group. Alkylation of piperidine 98 with 1-chloro-3-bromo propane in DMF in the presence of potassium carbonate provided the chloride intermediate 99 in 80% yield. Subsequent reaction with phenol 100 under basic conditions gave the desired product iloperidone (VII) in 81% yield.
