Uses
Different sources of media describe the Uses of 146-54-3 differently. You can refer to the following data:
1. In psychiatric practice, triflupromazine is used for psychomotor excitement in patients
with schizophrenia for paranoid and manic-depressive conditions, and for neurosis.
2. Antipsychotic.
Definition
ChEBI: A member of the class of phenothiazines that is 10H-phenothiazine having a trifluoromethyl subsitituent at the 2-position and a 3-(dimethylamino)propyl group at the N-10 position.
Manufacturing Process
Approximately 3.8 grams of sodamide is freshly prepared from 2.25 grams of
sodium, 90 grams of liquid ammonia and a catalytic trace of ferric nitrate. The
ammonia is allowed to evaporate. A solution of 19.1 grams of 2-trifluoromethylphenothiazine (prepared by the Bernthsen thionation of 3-
trifluoromethyldiphenylamine) in 160 ml of dry benzene is added to the
reaction flask followed by 18 grams of 3-chloro-1-dimethylaminopropane. The
reaction mixture is heated at reflux for 20 hours. After washing the cooled
mixture with 130 ml of water, the organic layer is extracted with several
portions of dilute hydrochloric acid. The acid extracts are combined and
neutralized with ammonium hydroxide solution. The oily free base is extracted
into benzene and purified by distillation to give 19.6 grams of 10-(3'-
dimethylaminopropyl)-2-trifluoromethylphenothiazine, boiling point 177° to
181°C at 1 mm. The free base (7 grams) is converted to the hydrochloride
salt by reacting an alcoholic solution of the base with hydrogen chloride gas.
Evaporation of the volatiles in vacuo leaves an amorphous solid which is
recrystallized from ethanol/ether to pink crystals, MP 173° to 174°C, the
hydrochloride salt of the free base prepared above.

Safety Profile
Poison by ingestion,
intravenous, and intraperitoneal routes.
Experimental reproductive effects. Mutation
data reported. When heated to
decomposition it emits very toxic fumes of
F-, NOx, and SOx. See also FLUORIDES.
Synthesis
Triflupromazine, 2-trifluoromethyl-10-(3-dimethylaminopropyl) phenothiazine (6.1.3), also is synthesized by the alkylation of 2-trifluoromethylphenothiazine
using 3-dimethylaminopropylchloride in the presence of sodium amide [7–12].
Check Digit Verification of cas no
The CAS Registry Mumber 146-54-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,4 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 146-54:
(5*1)+(4*4)+(3*6)+(2*5)+(1*4)=53
53 % 10 = 3
So 146-54-3 is a valid CAS Registry Number.

A Focused Library of Psychotropic Analogues with Neuroprotective and Neuroregenerative Potential
Uliassi, Elisa,Pena-Altamira, Luis Emiliano,Morales, Aixa V.,Massenzio, Francesca,Petralla, Sabrina,Rossi, Michele,Roberti, Marinella,Martinez Gonzalez, Loreto,Martinez, Ana,Monti, Barbara,Bolognesi, Maria Laura

Overcoming the lack of effective treatments and the continuous clinical trial failures in neurodegenerative drug discovery might require a shift from the prevailing paradigm targeting pathogenesis to the one targeting simultaneously neuroprotection and neuroregeneration. In the studies reported herein, we sought to identify small molecules that might exert neuroprotective and neuroregenerative potential as tools against neurodegenerative diseases. In doing so, we started from the reported neuroprotective/neuroregenerative mechanisms of psychotropic drugs featuring a tricyclic alkylamine scaffold. Thus, we designed a focused-chemical library of 36 entries aimed at exploring the structural requirements for efficient neuroprotective/neuroregenerative cellular activity, without the manifestation of toxicity. To this aim, we developed a synthetic protocol, which overcame the limited applicability of previously reported procedures. Next, we evaluated the synthesized compounds through a phenotypic screening pipeline, based on primary neuronal systems. Phenothiazine 2Bc showed improved neuroregenerative and neuroprotective properties with respect to reference drug desipramine (2Aa). Importantly, we have also shown that 2Bc outperformed currently available drugs in cell models of Alzheimer's and Parkinson's diseases and attenuates microglial activation by reducing iNOS expression.
