440-17-5 Usage
Description
Trifluoperazine (TFP) is a phenothiazine compound with anti-adrenergic and anti-dopaminergic actions typical of antipsychotic agents. It antagonizes adrenergic receptors, with selectivity for α1 over the α2 subtypes (Kis = 24, 653, 163, and 391 nM for α1A, α2A, α2B, and α2C, respectively). TFP binds with much higher affinity to the dopamine D2-like receptor (Kd = 0.96 nM) compared to the dopamine D4-like and the serotonin 5-HT2A receptors (Kds = 44 and 135 nM, respectively). Furthermore, TFP antagonizes calmodulin (CaM) and alters the calcium-binding properties of calsequestrin (CSQ). TFP has been shown to activate type-2 ryanodine receptors independently of its CaM and CSQ activity.
Uses
Different sources of media describe the Uses of 440-17-5 differently. You can refer to the following data:
1. Trifluoperazine dihydrochloride has been used as a calmodulin kinase antagonist in cultured Aplysia californica neurons. Trifluoperazine dihydrochloride has also been used as a PMCA inhibitor in mouse duodenal tissues to block the transcellular active calcium flux.
2. Antipsychotic
Therapeutic Function
Tranquilizer
General Description
Trifluoperazinehydrochloride, 10-[3-(4-Methyl-1-piperazinyl)propyl-[2-(trifluoromethyl)phenothiazine dihydrochloride (Stelazine).The absorption of trifluoperazine is erratic and variable andit is widely distributed into tissues. The excretion of trifluoperazineoccurs 50% via kidneys and the other 50% isthrough enterohepatic circulation. The metabolism and druginteractions of trifluoperazine are the same as with the otherphenothiazines. Trifluoperazine does not show any specificdrug interactions. Trifluoperazine is indicated for the managementof schizophrenia and short-term treatment ofnonpsychotic anxiety.
Biochem/physiol Actions
Trifluoperazine dihydrochloride is useful in treating schizophrenia, disturbed behavior, severe anxiety, nausea and vomiting.
Safety Profile
Poison by intravenous
and intraperitoneal routes. Moderately toxic
by ingestion. Experimental reproductive
effects. Human mutation data reported.
When heated to decomposition it emits very
toxic fumes of F-, NOx, SOx, and HCl. See
also FLUORIDES.
Purification Methods
Recrystallise the salt from absolute EtOH, filter the crystals, dry them in vacuo and store them in tightly stoppered bottles because it is hygroscopic. It is soluble in H2O but insoluble in *C6H6, Et2O and alkaline aqueous solution. It has UV at 258 and 307.5nm (log 4.50 and 3.50) in EtOH (neutral species). [Craig max et al. J Org Chem 22 709 1957.] It is a calmodulin inhibitor [Levene & Weiss J Parmacol Exptl Ther 208 454 1978] and is a psychotropic agent [Fowler Arzneim.-Forsch 27 866 1977]. [Beilstein 27 III/IV 1353.]
Check Digit Verification of cas no
The CAS Registry Mumber 440-17-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,4 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 440-17:
(5*4)+(4*4)+(3*0)+(2*1)+(1*7)=45
45 % 10 = 5
So 440-17-5 is a valid CAS Registry Number.
