《Simultaneous determination of guaifenesin enantiomers and ambroxol HCl using 50-mm chiral column for a negligible environmental impactã€?was written by Tantawy, Mahmoud A.; Yehia, Ali M.; Aboul-Enein, Hassan Y.. Safety of trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride And the article was included in Chirality in 2019. The article conveys some information:

Chiral stationary phases are conveniently used for enantiomeric separation of drugs by liquid chromatog. Consumption of large volumes of hazardous solvents is considered as a common challenge for the sustainability of this technique. To this end, a columnar chromatog. has been adopted using 50-mm-length stationary phases. The study comprised five Phenomenex Lux cellulose- and amylose-based columns for the separation of guaifenesin (GUA) enantiomers. In addition, an exptl. design was used to optimize the gradient profile for the separation of racemic GUA and ambroxol HCl (AMB) binary mixture The chromatog. method was achieved using Lux Cellulose-1 (50 × 4.6 mm) as a chiral stationary phase and ethanol/water as a mobile phase with linear gradient elution of 20% to 70% ethanol in 6 min at a flow rate of 1.0 mL min-1 and UV detection at 270 nm. Linearity ranges were found to be 50 to 1000 μg mL-1 and 15 to 450 μg mL-1 for each GUA enantiomer and AMB, resp. Environmental, health and safety tool was used to assess and compare greenness of the proposed and reported methods. Short column indeed reduces the environmental impact by decreasing waste by about 60% and utilizing only 1-mL ethanol in the mobile phase. The proposed method is a safer alternative for the simultaneous determination of drugs in their combined pharmaceutical formulation. The method has been validated and compared favorably with a reported one. The results came from multiple reactions, including the reaction of trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride(cas: 23828-92-4Safety of trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride)

Category: alcohols-buliding-blocksOn October 2, 2020 ,《Trans-Selective and Switchable Arene Hydrogenation of Phenol Derivatives》 was published in ACS Catalysis. The article was written by Wollenburg, Marco; Heusler, Arne; Bergander, Klaus; Glorius, Frank. The article contains the following contents:

A trans-selective arene hydrogenation of abundant phenol derivatives catalyzed by a com. available heterogeneous palladium catalyst was reported. The described method tolerates a variety of functional groups and provides access to a broad scope of trans-configurated cyclohexanols as potential building blocks for life sciences and beyond in a one-step procedure. The transformation is strategically important because arene hydrogenation preferentially delivers the opposite cis-isomers. The diastereoselectivity of the phenol hydrogenation can be switched to the cis-isomers by employing rhodium-based catalysts. Moreover, a protocol for the chemoselective hydrogenation of phenols to cyclohexanones was developed.

And the article was published in Yakugaku Zasshi in 2021. Electric Literature of C13H19Br2ClN2O The author mentioned the following in the article:

Occupational exposure of pharmacists to drugs during powder drug preparation in dispensing pharmacies was investigated. First, we determined frequently prescribed tipepidine hibenzate and ambroxol hydrochloride suspended in the air of the dispensing room. The median concentration of the drugs in the air was 0.01 μg/m3 and 0.02 μg/m3, resp.; these values indicate that the air in the dispensing room was contaminated with powder drug. To estimate drug exposure during powder drug preparation, drug dust was collected near the nose of workers. Anal. of the active ingredients of the drugs used in the preparation revealed that eight drugs, including bethanechol, l-carbocisteine, and zonisamide, were detected in the range of 1.5-1220 μg/m3. Assuming that the respiratory volume of an adult was 0.008 m3/min, it was estimated that 0.4-36 μg of the ingredients were exposed per prescription by multiplying concentration, respiratory volume and sampling time (3-5 min). Furthermore, the effect of wearing a medical mask on the drug powder exposure was evaluated using a self-made apparatus When the amount of drug powder collected on filters that is either covered with or without a medical mask was compared, the covered filter exhibited reduced drug powder accumulation to less than 10% the amount collected on the uncovered filter. The present data suggested that a medical mask might decrease the drug dust allergies in dispensing pharmacists.trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride(cas: 23828-92-4Electric Literature of C13H19Br2ClN2O) was used in this study.

《Spatiotemporal distribution of Streptococcus agalactiae attenuated vaccine strain YM001 in the intestinal tract of tilapia and its effect on mucosal associated immune cells》 was written by Huang, Ting; Li, Li-Ping; Liu, Yu; Luo, Yong-Ju; Wang, Rui; Tang, Jia-You; Chen, Ming. Synthetic Route of C13H19Br2ClN2O And the article was included in Fish & Shellfish Immunology on April 30 ,2019. The article conveys some information:

In the current study, the tilapia was orally vaccinated by the attenuated Streptococcus agalactiae(S. agalactiae) strain YM001, and the distribution and the pathol. effect of strain YM001 in different intestinal segments of tilapia were evaluated by real-time PCR(qPCR), immunohistochem.(IHC) and histomorphol. The qPCR results showed that the number of bacteria was the highest in the intestinal tracts at 12 h post oral gavage in the YM001 group, then began to decrease sharply and eliminated at 7 d. And the number of bacteria was highest in the foregut, hindgut, and rectum at 12 h, 24 h, and 3 d, resp. IHC indicated that bacteria mainly distributed in the margin epithelium and the goblet cells at 12 h – 24 h, and in the submucosa and muscle layer in the YM001 group in 3 d post gavage, then almost disappeared at 7 d. Histol. examination of intestines post gavage displayed that an inflammation was observed at 7 d in the YM001 group and the intestinal structure was fully recovered at 15 d. and the intestinal structure was fully recovered at 15 d. The attenuated S. agalactiae vaccine strain YM001 could enter the intestinal tissue after oral gavage and had a strong spatial and temporal selectivity in the intestinal tract, which could cause obvious mucosal immune response and mild pathol. reaction, but the pathol. change could be gradually repaired with the extinction of bacteria in the body. In the experiment, the researchers used many compounds, for example, trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride(cas: 23828-92-4Synthetic Route of C13H19Br2ClN2O)

Application of 23828-92-4On March 25, 2020, Zheng, Rui; Tao, Liyuan; Kwong, Joey S. W.; Zhong, Changming; Li, Chengyu; Chen, Shiqi; Sun, Yang; Zhang, Xiaoyu; Shang, Hongcai published an article in Journal of Ethnopharmacology. The article was 《Risk factors associated with the severity of adverse drug reactions by Xiyanping injection: A propensity score-matched analysis》. The article mentions the following:

Xiyanping injection (XYP), extraction of Andrographis paniculate (Andrographis paniculata (Burm. f.) Nees, chuan xin lian), is a Chinese patent medicine approved to treat bronchitis in China. In 2017, safety incidents associated with treatment of XYP began to emerge throughout China. However, the risk factors of severity of adverse reactions by XYP remain uncertain. To determine risk factors for the severity of XYP-associated adverse drug reactions (ADRs). We analyzed a total of 26,317 cases of ADRs linked to the use of XYP injection in the China National Adverse Drug Reaction Monitoring Information System from 2004 to 2017. Data were analyzed with respect to age, gender, ethnicity, previous ADRs, family history of ADRs, dosage specification, medication frequency specification, body weight, route of administration, herb-drug interactions (ribavirin, cefatriaxone, penicillin sodium, ambroxol hydrochloride, clindamycin, cefoxitin sodium, azithromycin, ceftazidime, amoxicillin sodium and clavulanate potassium, levofloxacin, cefazolin sodium pentahydrate, acyclovir) by univariate anal. and multivariate anal. Propensity score matching was used to compare severity of (general or serious) ADRs. We included 24,911 cases of general ADRs and 1406 cases of serious ADRs. Univariate anal. identified age (p < 0.001), body weight (p < 0.001), route of administration (p = 0.008), co-administration of XYP with ribavirin (p = 0.031) as risk factors of severity of ADRs. Multivariate anal. identified XYP + ribavirin combination (p = 0.048) and age (p < 0.001) as the independent risk factors. Upon propensity score matching, the variables were relatively balanced amongst the two groups of patients with general or severe ADRs, and the level of severity in patients who received treatment of XYP + ribavirin increased (p = 0.020). Age and co-administration of ribavirin may be potential risk factors for the severity of XYP-associated ADRs. This reminds us to pay more attention to the safety of elderly medication. Minimizing the herb-drug-interaction effects of XYP and ribavirin is a viable treatment target for healthcare professionals in managing serious ADRs amongst patients receiving XYP injection.

And the article was published in BioMed Research International in 2021. Quality Control of trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride The author mentioned the following in the article:

There is no better treatment method towards paraquat-induced acute lung injury (ALI) at present. Ambroxol combined with methylprednisolone exhibits a significant improvement effect on ALI treatment, whereas their mechanism in ALI is still unclear. 64 Patients with ALI caused by paraquat poisoning brought to author’s hospital from Jan. 2015 to Jan. 2018 were selected. They were separated into a combined treatment group (CTG) and a routine treatment group (RTG) on the basis of different treatment methods. The survival of patients was observed after 7 days of treatment. Arterial blood gas, oxygen partial pressure (PaO2), partial pressure of carbon dioxide (PaCO2), oxygenation index (PaO2/FiO2), patient’s spontaneous respiratory rate (RR), tidal volume (VT), and pos. end-expiratory pressure (PEEP) were observed before and after treatment for 7 days. Interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) were analyzed. The differences of indexes between the dead patients and the survivors were observed, and the potential predictive value of death was analyzed. After treatment, the indexes of patients were significantly improved in both groups compared with those before therapy. Further comparison showed that the improvement of PaO2, PaCO2, and PaO2/FiO2 in CTG was obviously higher than that in RTG (p < 0.05). The improvement of RR, PEEP, and VT in CTG was obviously higher than that in RTG (p < 0.05). The decreased degree of IL-6 and TNF-α in CTG was higher than that in RTG (p < 0.05). The 7-day mortality rate of 64 patients was 39.06%, and there was no obvious difference in the 7-day survival rate in both groups (p = 0.649). IL-6 and TNF-α were expected to be potential prediction indexes of paraquat-induced ALI. Ambroxol combined with methylprednisolone significantly improved the oxygen partial pressure and oxygenation index of patients with paraquat-induced ALI and inhibited the inflammatory response of patients.

In 2020,Letters in Applied Microbiology included an article by Wang, Y.; Li, X.; Wang, D.; Sun, S.; Lu, C.. Related Products of 23828-92-4. The article was titled 《In vitro interactions of ambroxol hydrochloride or amlodipine in combination with antibacterial agents against carbapenem-resistant Acinetobacter baumannii》. The information in the text is summarized as follows:

The aim of this study was to investigate the in vitro interactions of ambroxol hydrochloride (ABH) or amlodipine (AML) with commonly used antibacterial agents, including meropenem, imipenem-cilastatin sodium, biapenem, cefoperazone-sulbactam, polymyxin B, and tigecycline, against six carbapenem-resistant Acinetobacter baumannii (CRAB) clin. isolates. Drug interactions were interpreted using two models, i.e., the fractional inhibitory concentration index (FICI) model and the percentage of growth difference (ΔE) model. The results show that a majority of the combination groups exhibited partial synergy and additive interactions, such as the combinations of carbapenems and cefoperazone-sulbactam (SCF) with ABH or AML. While the combination of PB/AML exhibited synergistic interactions against all tested isolates, and PB/ABH exhibited synergistic interactions against two isolates. The FICI and ΔE model correlated very well for the combinations of PBABH and PB/AML against AB2. The combinations of TGC with ABH or AML mainly exhibited additive and indifferent interactions. There were no antagonistic interactions observed in any of the combinations. In conclusion, this study revealed that the non-antibacterial agents ABH or AML can work synergistically or partial synergistically with antibacterial agents against CRAB. This finding is crucial for overcoming the carbapenem resistance of A. baumannii. 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: 23828-92-4Related Products of 23828-92-4) was used in this study.
