Product introduction:
| Melting Point | 177-179°C(lit.) |
| Boling Point | 409.3°C at 760 mmHg |
| Flash Point | 201.4°C |
| Solubility | DMSO (Slightly, Heated), Methanol (Slightly) |
| Vapor Presure | 1.96E-07mmHg at 25°C |
| Appearance | Solid |
| Color | Crystals from Me2CO |
| Merck | 14,1029 |
| Storage Condition | Keep in dark place,Sealed in dry,Room Temperature |
| Physical and Chemical Properties | White or almost white crystalline powder. Melting point 177-181 °c. 14.9g of the product can be dissolved in of water at 25 C, and it is almost insoluble in ether. No odor, slightly bitter taste. The base ([302-40-9]) had a melting point of 51 °c. |
| In vitro study | Benactyzine hydrochloride and drofenine are widely used anticholinergic drugs which are also competitive inhibitors of BChE with K i values of 0.010±0.001 and 0.003±0.000 mM, respectively. Results indicate that the inhibition of BChE by Benactyzine hydrochloride is pure or partial competitive. Pure competitive inhibition can be distinguished from partial competitive inhibition by plotting v vs [Benactyzine] at a fixed [BTCh]. |
| In vivo study | Benactyzine hydrochloride (1 mg/kg) does not influence the attention response. Benactyzine hydrochloride increases the duration of the exploratory-motor reaction, but slightly diminishes the salivation elicited by acetylcholine. There is no blocking effect of Benactyzine hydrochloride and promazine on the EEG-seizure activity elicited by acetylcholine, and almost no inhibitory effect on emotional reactions. Emotional reactions are blocked by high doses of imipramine and promazine, but not by Benactyzine hydrochloride. The data indicates that imipramine, promazine and Benactyzine hydrochloride influence the autonomic effects of serotonin in different ways. Promazine, and especially Benactyzine hydrochloride, inhibit and shorten the period of salivation elicited by the intra-amygdaloid injection of serotonin. |
| BENACTYZINE HYDROCHLORIDE Usage And Synthesis |
| Originator | Suavitil,Merck Sharp and Dohme,US,1957 |
| Uses | Benactyzine Hydrochloride is an antagonist of acetylcholine in the central and peripheral nervous system. Benactyzine Hydrochloride is used as an antispasmodic. |
| Manufacturing Process | 114 parts of ethyl benzilate, 175 parts of β-diethylaminoethanol and 0.2 part of metallic sodium were placed in a flask attached to a total-reflux variable take-off fractionating column. The pressure was reduced to 100 mm and heat was applied by an oil bath the temperature of which was slowly raised to 90°C. During three hours of heating 17 parts of ethanol distilled (35.5°C). When the distillation of the ethanol became slow, the bath temperature was raised to 120°C. When the vapor temperature indicated distillation of the amino alcohol the take off valve was closed and the mixture was refluxed for one hour. At the end of this period the vapor temperature had dropped and two more parts of ethanol were distilled, The remaining aminoalcohol was slowly distilled for three hours. The pressure was then reduced to 20 mm and the remainder of the aminoalcohol distilled at 66°C. During the reaction the color of the solution changed from yellow to deep red. The residue was dissolved in 500 parts of ether, washed once with dilute brine, and three times with water, dried over sodium sulfate and finally dried over calcium sulfate. 500 parts of a saturated solution of HCl in absolute ether was added and the resulting precipitate filtered. Dry HCl gas was passed into the filtrate to a slight excess and the precipitate again filtered. The combined precipitates were washed with cold acetone. The 106 parts of product was purified by recrystallization from acetone as fine white crystals which melt at 177°- 178°C. |
