COA of Formula: C13H19Br2ClN2OOn May 31, 2021, Pobudkowska, Aneta; Sliwinska, Agnieszka; Nosol, Kamil published an article in Journal of Solution Chemistry. The article was 《Physicochemical Properties and Solubility of Hydrochloride Mucolytic Agents》. The article mentions the following:

Two widely used active pharmaceutical ingredients (API), ambroxol hydrochloride (AMB·HCl) and bromhexine hydrochloride (BMH·HCl), belong to the expectorant and mucokinetic group of drugs. Their applications are found in the treatment of the upper respiratory tract and bronchopulmonary diseases. The compounds have similar chem. structures, but are different enough to distinguish their physicochem. properties. To understand better the bioavailability of the drugs a series of experiments was performed to establish significant parameters. With differential scanning calorimetry (DSC) the temperature and the enthalpy of fusion were determined with no observed polymorphic transformations. The phase diagrams for binary systems {active agent (1) + solvent (2)} were determined with three solvents: 1-octanol, water and ethanol, to describe phase equilibrium by correlation with the local composition models: Wilson, UNIQUAC and NRTL. Finally, the Bates-Schwarzenbach method was used to establish the ionization constants of AMB·HCl and BMH·HCl at two temperatures: room temperature 298.2 K and human body temperature 310.2 K. Our study can give an insight into further drug delivery system design and help to create more effective drug application forms. The results came from multiple reactions, including the reaction of trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride(cas: 23828-92-4COA of Formula: C13H19Br2ClN2O)

Liu, Hongbo; Wang, Wenxiao; Gao, Xingjuan published their research in Experimental and Therapeutic Medicine on December 31 ,2020. The article was titled 《Comparison of the efficacy of ambroxol hydrochloride and N-acetylcysteine in the treatment of children with bronchopneumonia and their influence on prognosis》.Formula: C13H19Br2ClN2O The article contains the following contents:

The aim of the present study was to compare the efficacy of ambroxol hydrochloride and N-acetylcysteine in the treatment of children with bronchial pneumonia and their influence on prognosis. A total of 120 children with bronchial pneumonia, admitted to The Affiliated Yantai Yuhuangding Hospital of Qingdao University from July 2015 to August 2018, were enrolled in the study. Among them, 58 children were treated with N-acetylcysteine and comprised the exptl. group, and 62 children were treated with ambroxol hydrochloride and comprised the control group. Children’s phys. signs (such as fever, short breath, cough and pulmonary rales) and the adverse reactions to treatment were observed, and the disappearance time of the signs was recorded. In addition, the cellular immune function indicators and the quality of life after treatment were investigated. There was no significant difference in clin. data between the two groups (P>0.05). The effective rate in the exptl. group was significantly higher than that in the control group (P<0.05). The disappearance time of symptoms, such as fever, cough, asthma and rales in the lung, was significantly shorter in the exptl. group than that in the control group (P<0.05). The hospitalization time of patients in the exptl. group was shorter than that in the control group (P<0.05). After treatment, IgA (IgA), IgG (IgG), IgM (IgM) and complement C3 were significantly increased in the exptl. group (P<0.01), and the IgA and IgG in the exptl. group were significantly higher than those in the control group (P<0.01). The incidence of adverse reactions in the exptl. group was significantly lower than that in the control group (P<0.05). In conclusion, N-acetylcysteine has a significant effect on the treatment of bronchopneumonia in children providing a quick relief from symptoms, such as lung rales, and therefore is worthy of use in clinic. In the experiment, the researchers used many compounds, for example, trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride(cas: 23828-92-4Formula: C13H19Br2ClN2O)

The author of 《Efficacy of high-dose ambroxol for paraquat poisoning: a meta-analysis of randomized controlled trials》 were Wang, Junwu; Yu, Wensu; Wu, Na; Gitonga, Elaine N.; Shen, Haitao. And the article was published in Journal of Research in Medical Sciences in 2020. Formula: C13H19Br2ClN2O The author mentioned the following in the article:

Background: Paraquat (PQ) poisoning is characterized by rapidly progressive acute poisoning with high mortality and no specific antidote. Although some clin. studies have been conducted to investigate the benefits of high-dose ambroxol as an adjuvant treatment for PQ poisoning, the efficacy is controversial. Materials and Methods: After searching for relevant articles in English and Chinese databases from 1978 to 2019 according to the keywords (paraquat poisoning/methy viologen/gramoxone, and ambroxol/mucosolvan/Bromhexine), we found seven articles that met our inclusion and exclusion criteria. A meta-anal. was performed using fixed-effects model and random-effects model according to the I2 value in Stata software (version 15.0). Four outcome indicators (hospital mortality, partial pressure of oxygen (PaO2), oxygenation index (PaO2/FiO2), and survival time of the deceased patients) were of interest to us. Results: The meta-anal. showed that adjuvant treatment with high doses of ambroxol increased PaO 2 (weighted mean difference [WMD] = 13.73 [mmHg], 95% confidence interval [CI]: 8.68-18.79, Z = 11.80, P < 0.001), PaO 2/FiO2 (WMD = 38.81 [mmHg], 95% CI: 29.85-47.76, Z = 8.49, P = 0.000), and survival time of the deceased patients (WMD = 2.58 [d], 95% CI: 0.97-4.18, Z = 3.15, P = 0.002) compared with usual treatment. Treatment with high doses of ambroxol also appeared to reduce the hospital mortality (relative risk = 0.69, 95% CI: 0.55-0.86, Z = 3.25, P = 0.001). Conclusion: This study found that high-dose ambroxol is an effective therapy for PQ poisoning and may reduce the in-hospital mortality. In addition to this study using trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride, there are many other studies that have used trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride(cas: 23828-92-4Formula: C13H19Br2ClN2O) was used in this study.

The information in the text is summarized as follows:

To evaluate the effects of ambroxol hydrochloride on lung tissue cell apoptosis and vascular remodeling in rats with smoke induced chronic obstructive pulmonary disease. Sprague Dawley rats were randomly divided into normal, model, exptl. and control groups (n=20). The rat model of chronic obstructive pulmonary disease was established by fumigation using Yan′an Cigarettes for 64 d. After fumigation, the exptl. and control groups were s.c. injected with 5 mL of Ambroxol hydrochloride (20 mg/kg) and 5 mL of Bambuterol hydrochloride (20 mg/kg) resp., while the normal and model groups were i.p. injected with an equal dose of normal saline. Following drug intervention for 28 d, the pathol. changes in lung tissues, vascular remodeling, lung tissue cell apoptosis, expressions of alpha-smooth muscle actin and vascular endothelial growth factor, as well as levels of caspase-3, B-cell lymphoma-2 and B-cell lymphoma-2 associated X protein were detected by hematoxylin and eosin staining, elastic Van Gieson staining, terminal deoxynucleotidyl transferase dUTP nick end labeling staining, immunohistochem. staining and western blotting, resp. Compared with normal group, the damage of lung tissues was obvious, the medial thickness of pulmonary arterioles significantly increased, the degree of vascular muscularization, apoptosis rate and expressions of alpha-smooth muscle actin, vascular endothelial growth factor, caspase-3 and B-cell lymphoma-2 associated X protein rose and the expression of B-cell lymphoma-2 decreased in model group (p<0.05). Compared with model group, the damage of lung tissues was significantly improved, the medial thickness of pulmonary arterioles decreased, the degree of vascular muscularization, apoptosis rate and expressions of alpha-smooth muscle actin, vascular endothelial growth factor, caspase-3 and B-cell lymphoma-2 associated X protein reduced and the expression of B-cell lymphoma-2 rose in exptl. and control groups (p<0.05).

Clin. efficacy of pulmonary surfactant combined with high-dose ambroxol hydrochloride in the treatment of neonatal respiratory distress syndrome (NRDS) was investigated. One hundred child patients with NRDS in Linyi Central Hospital were collected according to the diagnostic criteria for RDS in the Pediatrics, and randomly divided into the treatment group (n=50) and the control group (n=50) based on different therapeutic methods. Patients in the control group were treated with basic treatment and high-dose ambroxol hydrochloride injection, while those in the treatment group were addnl. administered with pulmonary surfactant Curosurf based on conventional therapy in the control group. The chest X-rays were collected before the treatment and at 12 h after the drug administration, the degree of respiratory distress in child patients was observed and evaluated via Silverman grading, and changes in blood gas indexes were recorded before treatment and at 2, 6 and 12 h after the drug administration. The chest X-ray grade, Silverman grade and blood gas anal. results had no differences between the two groups before the treatment (P>0.05). In the treatment group, partial pressure of oxygen (PaO2) and PH were increased and partial pressure of carbon dioxide (PaCO2) was decreased compared with those in the control group at 2, 6 and 12 h after the drug administration (P<0.05). At 12 h after the drug administration, chest X-ray grade and Silverman grade in both groups were improved, which were significantly superior in the treatment group to those in the control group (P<0.01). Moreover, the efficacy in the treatment group was remarkably better than that in the control group at 12 h after drug administration (P<0.01). Pulmonary surfactant combined with high-dose ambroxol hydrochloride has definite efficacy in the treatment of NRDS, which can significantly improve the pulmonary infection, respiratory distress and blood gas indexes of child patients.

Wang, Diana J.; Targos, Karina; Wickens, Zachary K. published their research in Journal of the American Chemical Society on December 29 ,2021. The article was titled 《Electrochemical Synthesis of Allylic Amines from Terminal Alkenes and Secondary Amines》.Safety of trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride The article contains the following contents:

Allylic amines are valuable synthetic targets en route to diverse biol. active amine products. Current allylic C-H amination strategies remain limited with respect to the viable N-substituents. Herein, authors disclose a new electrochem. process to prepare aliphatic allylic amines by coupling two abundant starting materials: secondary amines and unactivated alkenes. This oxidative transformation proceeds via electrochem. generation of an electrophilic adduct between thianthrene and the alkene substrates. Treatment of these adducts with aliphatic amine nucleophiles and base provides allylic amine products in high yield. This synthetic strategy is also amenable to functionalization of feedstock gaseous alkenes at 1 atm. In the case of 1-butene, high Z-selective crotylation is observed This strategy, however, is not limited to the synthesis of simple building blocks; complex biol. active mols. are suitable as both alkene and amine coupling partners. Preliminary mechanistic studies implicate vinylthianthrenium salts as key reactive intermediates.
