In 2020,World Journal of Pharmaceutical Research included an article by Naykodi, Pradnya S.; Bidkar, Shital J.; More, Komal V.; Dighe, Ajinkya D.. Category: alcohols-buliding-blocks. The article was titled 《Taste masking of bitter drugs by using ion exchange resin method》. The information in the text is summarized as follows:

The various organoleptic properties such as taste, smell, texture also these are important factor in development of oral dosage forms. The taste is the major factor that affect the patient compliance and product quality. Acceptability of any dosage form mainly depends over its taste i.e. mouth feel. Drug mol. interact with taste receptor on the tongue to give bitter, sweet or other taste sensation, when they dissolve in saliva. The taste buds shows the sensation of taste by signal transduction from the receptor organs. Now a days most of the potent drugs that are cardiac, analgesic, anti-inflammatory, anti-tubercular, antibacterial, anthalmetics, antimalarial, antiepileptics, anticoagulants, histamine receptor agonist, antithyroids, antineoplastic, antiprotozoal, diuretics, nutritional agents, opioid analgesic, sex hormones, vaccines most of them are bitter in taste. So it become a necessary to develop such a dosage form that is acceptable for its taste by patients especially children or geriatrics. It becomes a challenge for pharmacist to make palatable formulation by masking the bitter taste of the drug. In the part of experimental materials, we found many familiar compounds, such as trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride(cas: 23828-92-4Category: alcohols-buliding-blocks)

trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride(cas: 23828-92-4) is a medication indicated to alleviate chest congestion associated with conditions that include bronchitis, pneumonia, bronchospasm asthma, cough, and allergy.Category: alcohols-buliding-blocks Preclinically, ambroxol, the active ingredient of Mucosolvan, has been shown to increase respiratory tract secretion.

《Application of two advanced derivative spectrophotometric methods for simultaneous estimation of salbutamol sulphate, ambroxol hydrochloride and theophylline in pure and commercial formulations》 was written by Dave, H. N.; Mashru, R. C.. Reference of trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride And the article was included in International Journal of Current Pharmaceutical Research in 2022. The article conveys some information:

Two advanced spectrophotometric methods have been proposed for the simultaneous determination of Salbutamol sulfate, Ambroxol hydrochloride and Theophylline in pure and pharmaceutical formulations. The proposed methods exclude the hectic steps of time-consuming sample preparations or purification or separation steps. There is no any spectrophotometric method has been avail for simultaneous estimation of the ternary mixture containing Salbutamol sulfate, Ambroxol hydrochloride and Theophylline. The methods are derivative ratio spectra zero-crossing method and double divisor ratio spectra derivative method resp. Both the methods are found to be rapid, accurate, precise, reliable and economical as well. The developed methods show best results in terms of linearity, accuracy, precision, limit of detection and limit of quantification for standard laboratory mixtures of pure drugs and marketed formulations. The range for Salbutamol sulfate, Ambroxol hydrochloride and Theophyllineare found to be 1-35μg ml-1, 5-35μg ml-1 and 6-60μg ml-1 resp. For the derivative ratio spectra zero-crossing method, the values of the limit of detection are found to be 0.3161μg ml-1, 0.2212μg ml-1 and 0.2910μg ml-1 and the values limit of quantification are found to be 0.9571μg ml-1, 0.7412μg ml-1 and 0.9671μg ml-1 for Salbutamol sulfate, Ambroxol hydrochloride and Theophylline resp. For double divisor ratio spectra derivative method, limit of detection values is found to be 0.3251μg ml-1, 0.2591μg ml-1 and 0.2640μg ml-1 and the limit of quantification values are found to be 0.9870μg ml-1, 0.8650μg ml-1 and 0.8812μg ml-1 for Salbutamol sulfate, Ambroxol hydrochloride and Theophylline resp. The common excipients and additives did not interfere in the determinations of any of the drugs while being analyzed for com. formulations. These two spectrophotometric methods, which determine SS, AH, and THE simultaneously, are simple, specific, accurate, precise, rapidly, and economically, indicating that they can be used routinely in pharmaceutical anal. As a result, derivative spectrophotometry may be used effectively for the simultaneous determination of SS, AH and THE in the combined dosage forms without any prior separation of individual drugs. The experimental process involved the reaction of trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride(cas: 23828-92-4Reference of trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride)

Yu, Li; Bhattacharya, Dhruva; Wang, Zhenhan; Wang, Mingwu published an article in Graefe’s Archive for Clinical and Experimental Ophthalmology. The title of the article was 《Topical administration of ambroxol eye drops augments tear secretion in rabbits》.Synthetic Route of C13H19Br2ClN2O The author mentioned the following in the article:

To investigate if topical administration of ambroxol promotes tear secretion and to compare with Diquas ophthalmic eye drop. Two consecutive studies were conducted using sixteen (32 eyes) New Zealand White rabbits. The first study compared the efficacy of ambroxol hydrochloride (0.05%, 0.2%, and 1.0%) on tear and mucin secretion when administered twice daily. Tear secretion was assessed by Schirmer test I and mucin production by conjunctival impression cytol. and PAS stain. The second study compared 0.2% ambroxol hydrochloride with Diquas. A human goblet cell line and human conjunctival tissue were used to test the effect of ambroxol hydrochloride on the expression of aquaporin 5 (AQP5) and MUC5AC, using reverse transcriptase-quant. polymerase chain reaction and immunoblotting. All three concentrations of ambroxol hydrochloride demonstrated significant efficacy on tear stimulation within 2 wk of treatment and total mucin component appeared increased. When administered topically twice daily, 0.2% ambroxol hydrochloride was more effective in augmenting tear secretion than Diquas. With 24 h of treatment, 5μM of ambroxol hydrochloride upregulated AQP5 and MU5AC mRNA and MUC5AC protein in a goblet cell line. When tested on preserved human conjunctiva tissue, a trend of increased production of MUC5AC protein was seen (P = 0.26). Ambroxol is effective in augmenting tear secretion at the ocular surface in rabbits. With actions desirable of a candidate dry eye drug, further investigation of ambroxol and related compounds is warranted to explore their value toward clin. application. The experimental part of the paper was very detailed, including the reaction process of trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride(cas: 23828-92-4Synthetic Route of C13H19Br2ClN2O)

And the article was published in Journal of Pediatric Gastroenterology and Nutrition in 2020. Related Products of 23828-92-4 The author mentioned the following in the article:

The aim of this study was to assess common laboratory tests in identifying severe ulcerative colitis in children at diagnosis. A cohort of 427 children 4 to 17 years of age newly diagnosed with ulcerative colitis (UC) was prospectively enrolled. Boosted classification trees were used to characterize predictive ability of disease attributes based on clin. disease severity using Pediatric Ulcerative Colitis Activity Index (PUCAI), severe (65+) vs. not severe (<65) and total Mayo score, severe (10-12) vs. not severe (<10); mucosal disease by Mayo endoscopic subscore, severe (3) vs. not severe (<3); and extensive disease vs. not extensive (left-sided and proctosigmoiditis). Mean age was 12.7 years; 49.6% (n = 212) were girls, and 83% (n = 351) were Caucasian. Severe total Mayo score was present in 28% (n = 120), mean PUCAI score was 49.820.1, and 33% (n = 142) had severe mucosal disease with extensive involvement in 82% (n = 353). Classification and regression trees identified white blood cell count, erythrocyte sedimentation rate, and platelet count (PLT) as the set of 3 best blood laboratory tests to predict disease extent and severity. For mucosal severity, albumin (Alb) replaced PLT. Classification models for PUCAI and total Mayo provided sensitivity of at least 0.65 using standard clin. cut-points with misclassification rates of approx. 30%. A combination of the white blood cell count, erythrocyte sedimentation rate, and either PLT or albumin is the best predictive subset of standard laboratory tests to identify severe from nonsevere clin. or mucosal disease at diagnosis in relation to objective clin. scores.
