  ChEBI: A piperazine compound having 1,2-benzothiazol-3-yl- and 2-(6-chloro-1,3-dihydro-2-oxindol-5-yl)ethyl substituents attached to the nitrogen atoms.

• Manufacturing Process

  Preparation of 5-[2-[4-(1,2-benzisothiazol-3-yl)-1-piperazinyl]ethyl]-6-chloro- 1,3-dihydro-2H-indol-2-one
  A 20-gallon glass lined tank, under a nitrogen atmosphere, was charged with 33.5 liters of water and 9.4 kilograms (kg) of sodium carbonate (dense, 89.1 moles, 3.4 eq.). The resulting mixture was stirred to give a solution. To the solution 6.4 kg of 2-chloroethyl-6-chloro-oxindole (27.8 moles, 1.06 eq.) was charged, followed by 6.7 kg of 3-piperazinyl-1,2-benzisothiazole hydrochloride (26.2 moles, 1.0 eq.). This was stirred and heated to reflux (100°C). After 11 hours the reaction was sampled for high pressure liquid chromatography (HPLC) assay. The reflux was continued for another 2 hours then the reaction was cooled to 25°C and the slurry stirred for 1 hour. The product was observed and found to be essentially free from lumps and gummy matter. The product was collected by filtration. A 14 liter water was added to the tank and cooled to 12°C and then used to wash the product. The cake was pulled as dry as possible, and the product was returned to the tank along with 40 liters of isopropyl alcohol (IPO). This was cooled and then stirred for 2 hours and the product was collected by filtration. The cake was washed with 13.4 liters of fresh IPO, then dried under vacuum at 30° to 40°C. After drying, 17.3 kg of the title compound was obtained. This was in excess of the theoretical weight yield due to some residual carbonate in the crude product.
  Recrystallization of 5-[2-[4-(1,2-benzisothiazol-3-yl)-1-piperazinyl]ethyl]-6- chloro-1,3-dihydro-2H-indol-2-one
  To a clean and dry 100-gallon glass lined tank was charged 9.0 kg of the material obtained above and 86 gallons of tetrahydrofuran (THF). The slurry was heated to reflux and held for 1 hour. The hazy solution was then filtered through a 14" sparkler precoated with filter aid and backed with a Fulflo filter to a clean, dry, and "spec free" glass-lined tank on a lower level. The batch was concentrated by vacuum distillation. Another 8.3 kg of the material obtained in above was dissolved in 83 gallons of THF in the upper tank. This was filtered to the lower tank. The tank lines and sparkler were rinsed with 10 gallons of THF. The batch was concentrated to about 22 gallons, then cooled to 5°C and stirred for 1 hour. The product was collected by filtration. Then 20 gallons of fresh IPO were cooled in the tank and used to rinse the product cake. The product was collected and dried under vacuum at 45°C; yielding 9.05 kg of product (83.8% yield for the coupling and recrystallization. The product matched the spectra of a standard NMR and showed the correct retention time by HPLC with 99.7% assay. Another way for preparation of 5-(2-(4-(1,2-benzisothiazol-3-yl)-piperazinyl)ethyl)-6-chloro-1,3-dihydro-2-H- indol-2-one.
  A clean and dry 20-gallon glass lined tank was charged with 19 L of water and 4.44 kg of sodium carbonate, after the carbonate had dissolved 4.29 kg (17.5 moles) of 5-(2-chloroethyl)-6-chloro-oxindole and 3.62 kg (16.5 moles) of 1- (1,2-benzisothiazol-3-yl)piperazine were added. The aqueous slurry was heated to reflux and the temperature maintained for 14 hours. When the reaction was complete the solution was cooled to 20°C and filtered. The wet product was reslurried in 23 L of isopropyl alcohol at room temperature for 2 hours. The product was collected by filtration on 2 large Buchner funnels, each was washed with 3.4 L of fresh isopropyl alcohol. The product was vacuum dried at 30° to 40°C. until no isopropyl alcohol remained, giving 5.89 kg (86.4% yield) of the desired free base which matched a standard sample by high performance liquid chromatography (HPLC).
  A clean and dry 20-gallon reactor was charged with 17.4 gallons of deionized water and 4.44 L of concentrated hydrochloric acid, to give a 0.77 M solution. To the solution was added 4.44 kg of the anhydrous 5-(2-(4-(1,2- benzisothiazol-yl)-1-piperazinyl)-ethyl)-6-chloro-1,3-dihydro-2H-indol-2-one

• Biologische Funktion

  "Ziprasidone is chemically similar to risperidone but with a substitution of piperzinyl and benzisothiazole for piperidinyl and benzisoxazole and with minor aromatic modification. Like risperidone, ziprasidone is a high-affinity antagonist at 5-HT2A/C and D2 receptors as well as at adrenergic α1/α2 and histamine H1 receptors. Moreover, ziprasidone can activate 5-HT1A receptors that regulate dopaminergic neurotransmission in brain regions involved in critical cognitive functions. Thus, in addition to D2 partial agonism, 5-HT1A agonism is now thought to be an important pharmacological property for atypical antipsychotic drug efficacy.

• Allgemeine Beschreibung

  Ziprasidone (Geodon, a benzisothiazolpiprazinylindolonederivative) also has the structuralfeatures of a hybrid molecule between a butyrophenone antipsychoticand a trazodone-like antidepressant. It is highlymetabolized to four major metabolites, only one of which, Smethyldihydroziprasidone,likely contributes to its clinical activity. In humans, less than 5% of the dose isexcreted unchanged. Reduction by aldehyde oxidase accountsfor about 66% of ziprasidone metabolism; two oxidative pathwaysinvolving hepatic CYP3A4 account for the remainder.

• Allgemeine Beschreibung

  Ziprasidone, 5-[2-[4-(1,2-benzisothiazol-3-yl)-1-piperazinyl]ethyl]-6-chloro-1,3-dihydro-2H-indol-2-one, is available as the hydrochloride monohydrate for oral administration (Geodon) and as the mesylate trihydrate saltfor intramuscular (IM) injection. The compound is well absorbedwith peak plasma levels occurring at 6 to 8 hours afteroral administration. The oral absorption is enhanced approximatelytwofold in the presence of food. Ziprasidone isbound about 99% to plasma proteins, primarily to albuminand α1-acid glycoprotein. Ziprasidone is not displaced in thepresence of two highly protein bound drugs, warfarin andpropranolol. Ziprasidone is extensively metabolized withonly about 5 % of the drug excreted unchanged.23 In humans,two major pathways are responsible for the metabolism ofziprasidone: (a) oxidation by CYP3A4 (one third) and (b) reductionby aldehyde oxidase (two thirds).The combinedaction of these metabolic pathways leads to four majorcirculating metabolites: benzisothiazole piperazine sulfoxide(BITP-sulfoxide), benzisothiazole piperazine sulfone (BITPsulfone),ziprasidone sulfoxide, and S-methyldihydroziprasidone.

• Mechanism of action

  Ziprasidone (half-life, 6 hours) has an oral bioavailability of approximately 60%, which can be enhanced in the presence of fatty foods. It is extensively metabolized (<5% excreted unchanged) by aldehyde oxidase, which results in reductive cleavage of the S–N bond, and then by S-methylation. Ziprasidone also can undergo CYP3A4-catalyzed N-dealkylation and S-oxidation.
