The title of the article was 《Microsphere formulations of ambroxol hydrochloride: influence of Okra (Abelmoschus esculentus) mucilage as a sustained release polymer》.Name: trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride The author mentioned the following in the article:

Ambroxol hydrochloride (AH), a secretion-releasing expectorant, is a good candidate for sustained delivery. Mucilages are biodegradable, inexpensive carriers in microsphere formulations. The study aimed to prepare microspheres of AH using Okra mucilage obtained from pods of Abelmoschus esculentus combined with sodium alginate at various polymer/drug ratios. Okra mucilage was characterized for morphol., swelling, viscosity and flow properties. AH microspheres were prepared by ionic emulsification method and characterized using size, entrapment efficiency, swelling index and dissolution time (t50). A full 2 by 3 factorial exptl. design using three factors (Okra mucilage/alginate ratio X1; drug/polymer ratio X2; and polymer concentration X3), each at two levels, was used to determine the effects of formulation variables on the responses. Optimized formulations of AH microspheres had sizes ranging from 250.91 ± 16.22 to 462.10 ± 23.85μm; swelling index 1.35 ± 0.05 and 3.20 ± 0.03 and entrapment 55.70 ± 3.55-94.11 ± 4.50%. The microspheres exhibited sustained release of AH over a prolonged period as revealed by the dissolution time (t50) 2.85 ± 1.03-7.50 ± 0.96 h. Drug release kinetics generally followed zero order, implying that the process is constant and independent of the initial concentration of drug. Polymer concentration had the highest influence on microsphere size, entrapment efficiency and dissolution time while Okra/alginate ratio had the highest influence on swelling. Okra mucilage was a suitable polymer that could serve as an alternative to synthetic polymers in sustaining the release of ambroxol hydrochloride.

Safety of trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride. The article was titled 《Ambroxol hydrochloride improves motor functions and extends survival in a mouse model of familial amyotrophic lateral sclerosis》. The information in the text is summarized as follows:

Amyotrophic lateral sclerosis (ALS) is a multifactorial and fatal neurodegenerative disease. Growing evidence connects sphingolipid metabolism to the pathophysiol. of ALS. In particular, levels of ceramides, glucosylceramides, and gangliosides are dysregulated in the central nervous system and at the neuromuscular junctions of both animal models and patients. Glucosylceramide is the main precursor of complex glycosphingolipids that is degraded by lysosomal (GBA1) or non-lysosomal (GBA2) glucocerebrosidase. Here, we report that GBA2, but not GBA1, activity is markedly increased in the spinal cord, of SOD1G86R mice, an animal model of familial ALS, even before disease onset. We therefore investigated the effects of ambroxol hydrochloride, a known GBA2 inhibitor, in SOD1G86R mice. A presymptomatic administration of ambroxol hydrochloride, in the drinking water, delayed disease onset, protecting neuromuscular junctions, and the number of functional spinal motor neurons. When administered at disease onset, ambroxol hydrochloride delayed motor function decline, protected neuromuscular junctions, and extended overall survival of the SOD1G86R mice. In addition, ambroxol hydrochloride improved motor recovery and muscle re-innervation after transient sciatic nerve injury in non-transgenic mice and promoted axonal elongation in an in vitro model of motor unit. Our study suggests that ambroxol hydrochloride promotes and protects motor units and improves axonal plasticity, and that this generic compound is a promising drug candidate for ALS. In the experiment, the researchers used many compounds, for example, 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)

Secretory otitis media is a very common nonsuppurative inflammatory disease in otorhinolaryngol. Ambroxol hydrochloride helps to improve ciliary movement in the ear canal and promote the dissolution and discharge of secretions. However, its effect still lacks systematic evaluation. We conducted a meta-anal. of clin. studies to systematically evaluate the application effect of ambroxol hydrochloride. A computer-based search of the Chinese Biomedical Database (CBM), China National Knowledge Infrastructure (CNKI), PubMed, and Web of Science databases was conducted using the keywords “”Ambroxol hydrochloride”” & “”secretory otitis media””. Randomized controlled trials published after 2015 were selected and then screened and analyzed using RevMan 5.4 software. Ten studies involving a total of 998 patients were included. Meta-anal. showed that adding ambroxol hydrochloride to the original glucocorticoid treatment improved therapeutic efficacy [odds ratio (OR) = 4.95, 95% confidence interval (CI): 3.27, 7.50, P<0.00001], reduced tympanic pressure after treatment [mean difference (MD) = -19.04, 95% CI: -22.72, -15.36, P<0.00001], and increased the pure tone threshold (MD =6.37, 95% CI: 5.36, 7.37, P<0.00001), without increasing adverse reactions (OR = 0.51, 95% CI: 0.14, 1.85, P=0.30). On the basis of the original treatment of secretory otitis media, adding ambroxol hydrochloride treatment improved the therapeutic effect, reduced tympanic pressure after treatment, and improved the pure tone threshold (hearing), without increasing adverse reactions.

The objective of this study was to apply Design of Experiment (DoE) concept for development of stability indicating high-performance thin-layer chromatog. (HPTLC) method for assay of model drugs (Roxithromycin (ROXTM) and Ambroxol hydrochloride (AMBRX)) in marketed tablet formulations followed by validation of developed HPTLC method as per ICHQ2(R1). Box-Behnken exptl. design was applied to optimize chromatog. conditions and their effects on retardation factor (Rf) value. The developed HPTLC method was validated for specificity, linearity, accuracy, precision, and robustness. The ROXTM (Rf 0.42) and AMBRX (Rf 0.75) were well separated (Rs 2.06) from each other and from their resp. degradation products on HPTLC plate using optimized chromatog. conditions. The developed method was successfully validated and statistical anal. proved that the method is sensitive, specific (peak purity > 0.9999 for both ROXTM and AMBRX), accurate (98.59-101.14% and 99.96-101.76%, ROXTM and AMBRX, resp.) and precise (% RSD >1.0 for both ROXTM and AMBRX).

Product Details of 23828-92-4. The article was titled 《Preparation of novel functional drug particles embedded in a gelling-swelling layer (PEGS) for taste masking and subsequent rapid drug release》. The information in the text is summarized as follows:

The purpose of this research was to develop novel functional drug particles embedded in a gelling-swelling layer (PEGS) which are capable of achieving both taste-masking of unpalatable drugs and rapid drug elution. The functional particles had a three-layer structure consisting of a core drug layer, a gelling-swelling layer and an outer water-penetration control layer containing a water-insoluble polymer. The concept of formulation design was as follows: when water reaches the gelling-swelling layer, pulverized fine gelling-swelling particles gellate and swell from water absorption to form a rigid layer, thereby preventing drug release. After a defined lag time, the increased volume of the gelling-swelling layer breaks down the outer water-penetration control layer, leading to rapid drug release. In order to adapt this system for use in orally disintegrating tablets, PEGS were prepared at a size of about 250μm using a fine particle-coating method. Ambroxol hydrochloride was used as a model drug for bitterness and the effects of different gelling-swelling agents and water-insoluble polymers on drug release characteristics from PEGS were examined In in vitro dissolution tests, it was shown that the drug dissolution rate from PEGS could be suppressed to about 5% after 2 min and increased to more than 85% after 30 min by adjusting the composition and thickness of the outer layer. The PEGS expanded about 1.5-fold and the outer layer was ruptured after 5 min in water.

The article was titled 《Dispersion-Corrected DFT Methods for Applications in Nuclear Magnetic Resonance Crystallography》.Electric Literature of C13H19Br2ClN2O The article contains the following contents:

Nuclear elec. field gradient (EFG) tensor parameters depend strongly on electronic structures, making their calculation from first principles an excellent metric for the prediction, refinement, and optimization of crystal structures. Here, we use plane-wave d. functional theory (DFT) calculations of EFG tensors in organic solids to optimize the Grimme (D2) and Tkatchenko-Scheffler (TS) at.-pairwise force field dispersion corrections. Refinements using these new force field correction methods result in better representations of true crystal structures, as gauged by calculations of 177 14N, 17O, and 35Cl EFG tensors from 95 materials. The most striking result is the degree by which calculations of 35Cl EFG tensors of chloride ions match with experiment, due to the ability of these new methods to properly locate the positions of hydrogen atoms participating in H···Cl- hydrogen bonds. These refined structures also feature at. coordinates that are more similar to those of neutron diffraction structures than those obtained from calculations that do not employ the optimized force fields. Addnl., we assess the quality of these new energy-minimization protocols for the prediction of 15N magnetic shielding tensors and unit cell volumes, which complement the larger anal. using EFG tensors, since these quantities have different phys. origins. It is hoped that these results will be useful in future NMR crystallog. studies and will be of great interest to a wide variety of researchers, in fields including NMR spectroscopy, computational chem., crystallog., pharmaceutical sciences, and crystal engineering.

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.
