To study the preparation of the synthetic process of loperamide hydrochloride, a drug which was widely used in the treatment of acute diarrhea with low side effect. Loperamide hydrochloride was synthesized from 2, 2-diphenyl-4-hydroxybutyric acid-γ-lactone as raw material via ring-opening, SN2 substitution, acidylation, quaternization, condensation and salifying. In the first step, when the reaction time was 24 h and temperature was 25°C, the yield was 81%. In the second step, when the molar ratio of n(SOCl2):n(2,2-phenyl-4-bromobutyric acid)=2:1 and temperature was reflux, the content of 4-bromo-2, 2-diphenylbutyroyl chloride(4) was 97.25%. And the key intermediate dimethyl(tetrahydro-3, 3-diphenyl-2-furylidene)ammonium bromide(5) was obtained with the yield increased from 50%(literature reported) to 68% when the molar ratio of n(4):n(Na2CO3):dimethylamine=1.0:1.2:1.5 and temperature was 0∼5°C. When the molar ratio of n(5):n(4-p-chlorophenyl-4-piperidinol):n(Na2CO3)=1.0:1.2:1.1, loperamide(6) was obtained with yield of 85%. After simple salification, the target compound 1 was synthesized from(6) with the yield of 89.6%. The overall yield was 34% and its structure was characterized by IR, 1H-NMR, 13C-NMR and MS spectra. Some drawbacks in the literature was improved and the method was easy for synthesis and suitable for industrial manufacturing The experimental process involved the reaction of 4-(4-Chlorophenyl)piperidin-4-ol(cas: 39512-49-7).Application of 39512-49-7

On April 30, 2012, Ali, Imran; Gupta, Vinod K.; Singh, Prashant; Negi, Uma published an article.SDS of cas: 39512-49-7 The title of the article was Monitoring of haloperidol and its metabolites in plasma by SPE-RP-TLC spectrometry. And the article contained the following:

We describe a simple and inexpensive SPE-RP-TLC method for the monitoring and anal. of haloperidol and its metabolites in plasma. Anal. was carried out on RP-TLC plates containing C18 silica gel using methanol having 0.001% diethylamine as a mobile phase. The chromatograms were developed up to 10 cm for 65 min at 28 ± 10°C. Detection of haloperidol and its metabolites was done by placing the dried plates in normal glass iodine chamber. The quant. anal. of haloperidol and its metabolites were carried out by using UV-visible spectroscopy at 230 nm. RF values of haloperidol, metabolite I, metabolite II, and metabolite III in plasma samples were 0.22, 0.06, 0.16, and 0.87, resp., and their percentage recoveries were 85.0, 88.0, 87.0, and 77.0, resp. The detection limit of RP-TLC method for haloperidol was 1.0 mg mL-1 and for all the three metabolites I, II, III was 0.8 mg mL-1. The results show that the developed method may be used for higher recovery of drugs under consideration from biol. samples. The experimental process involved the reaction of 4-(4-Chlorophenyl)piperidin-4-ol(cas: 39512-49-7).SDS of cas: 39512-49-7

On January 14, 2022, Ghersi, Dario; Genaro-Mattos, Thiago C. published an article.Synthetic Route of 39512-49-7 The title of the article was Identifying Molecular Fragments That Drive 7-Dehydrocholesterol Elevation. And the article contained the following:

Medications having the unwanted side effect of inhibiting 7-dehydrocholesterol reductase (DHCR7), one of the last enzymes in the cholesterol biosynthesis pathway, account for about 300 million yearly prescriptions in the United States. Many of these drugs are currently prescribed to pregnant women. Many DHCR7-inhibiting medications share chem. similarities, which can be the active substructure responsible for the medication affinity to the enzyme. This work highlights a computational strategy to identify enriched fragments in a set of DHCR7-inhibiting medications. The computational approach used here involves systematic fragmentation of mols. using the molBLOCKS tool, followed by enrichment anal. The results of this approach highlight putative pharmacophores that might be responsible for the DHCR7-inhibiting activity of some of these medications. The identification of DHCR7-inhibiting substructures is an important step toward knowledge-based drug development and can improve the neurodevelopmental safety of medications. The experimental process involved the reaction of 4-(4-Chlorophenyl)piperidin-4-ol(cas: 39512-49-7).Synthetic Route of 39512-49-7

Favretto, Donata; Stocchero, Giulia; Nalesso, Alessandro; Vogliardi, Susanna; Boscolo-Berto, Rafael; Montisci, Massimo; Ferrara, Santo D. published an article in 2013, the title of the article was Monitoring Haloperidol Exposure in Body Fluids and Hair of Children by Liquid Chromatography-High-Resolution Mass Spectrometry.Related Products of 39512-49-7 And the article contains the following content:

Background: Haloperidol, 4-[4-(4-chlorophenyl)-4-hydroxy-1-piperidinyl]-1-(4-fluorophenyl)-1-butanone (HP), one of the most widely used antipsychotics in the treatment of schizophrenia, mania, and other psychiatric disorders, is frequently encountered in cases of unintentional pediatric intoxication because the ingestion of a small amount can cause significant toxic effects in children. For monitoring HP in suspected ingestions, a liquid chromatog.-high-resolution mass spectrometry method has been developed and validated in urine, blood, and hair samples. Methods: The analyte was extracted from 1 mL blood or urine by liquid/liquid extraction and from 5 mg of hair by micropulverized extraction; gradient elution on an Atlantis T3 column was realized using HP-d4 as an internal standard Pos. ion electrospray ionization and high-resolution mass spectrometry determination were performed in an Orbitrap mass spectrometer. Results: The method exhibited a r > 0.999 in the studied ranges (0.1-50 ng/mL in urine and blood and 0.1-50 ng/mg in hair) and a limit of quantification of 0.1 ng/mL for urine and blood and 0.1 ng/mg for hair; intra-assay and interassay relative SDs were always more than 18%. The method was applied to determine haloperidol in 3 children who were admitted to emergency departments. HP concentrations ranged from 2 to 21 ng/mL in urine, from not detected to 4.9 ng/mL in blood, and from 0.37 to 0.73 ng/mg in hair samples. Conclusions: The utilization of high-resolution/high-accuracy mass spectrometry in full scan mode allowed the identification of HP metabolites in urine and blood, thus unequivocally documenting the exposure to the drug. HP metabolites were structurally characterized by high-resolution multiple mass spectrometry. For the first time, a HP metabolite was detected in hair. The experimental process involved the reaction of 4-(4-Chlorophenyl)piperidin-4-ol(cas: 39512-49-7).Related Products of 39512-49-7

Schinina, Barbara; Martorana, Andrea; Colabufo, Nicola Antonio; Contino, Marialessandra; Niso, Mauro; Perrone, Maria Grazia; De Guidi, Guido; Catalfo, Alfio; Rappazzo, Giancarlo; Zuccarello, Elisa; Prezzavento, Orazio; Amata, Emanuele; Rescifina, Antonio; Marrazzo, Agostino published an article in 2015, the title of the article was 4-Nitro-2,1,3-benzoxadiazole derivatives as potential fluorescent sigma receptor probes.Product Details of 39512-49-7 And the article contains the following content:

New fluorescent derivatives for σ receptors were designed and synthesized. To achieve this purpose, a 4-nitro-2,1,3-benzoxadiazole fluorescent tag was connected through a piperazine linker to a modified skeleton derived from selected σ receptor agonists or antagonists. Compounds 5g, 7b, 7e and 7g displayed high σ1 affinity and low σ1/σ2 selectivity (Kiσ1 ranging from 31.6 nM to 48.5 nM, Kiσ1/σ2 = 5-18), while compound 5d exhibited high σ2 affinity and selectivity (Kiσ2 = 56.8 nM, Kiσ1 > 5000 nM). Binding affinity studies revealed that compounds 5d, 5g, 7b, 7e and 7g showed no affinity towards several receptors including opioid, dopaminergic, serotonergic, adrenergic, muscarinic, histaminergic, N-methyl-D-aspartate (NMDA), NMDA receptor channel, or dopamine and serotonin transporters. The fluorescent properties, cellular uptake and confocal microscopy studies on 5d suggest a potential use of this probe to further clarify the mol. role of σ2 receptor subtypes in normal and cancer cells. The experimental process involved the reaction of 4-(4-Chlorophenyl)piperidin-4-ol(cas: 39512-49-7).Product Details of 39512-49-7
