Characterization of Photodegradation Products of Bepotastine Besilate and In Silico Evaluation of Their Physicochemical, Absorption, Distribution, Metabolism, Excretion and Toxicity Properties

Bepotastine (BPT) is a H1-receptor antagonist. It is used as a besilate salt in ophthalmic solution for allergic conjunctivitis and orally for the treatment of allergic rhinitis and urticaria/pruritus. Its systematic forced degradation study is unreported. The same was carried out in different conditions prescribed by International Conference on Harmonisation. The stressed solutions were subjected to reversed phase liquid chromatographic analysis, and BPT was observed to be labile under photobasic condition only, yielding 5 photodegradation products. The structures of the latter were elucidated from data generated by liquid chromatography–high-resolution mass spectrometry and multistage mass spectrometry. Of the 5, 4 products were further isolated and subjected to nuclear magnetic resonance spectroscopy to justify the proposed structures. Two of them, with similar accurate mass, were additionally and unambiguously characterized from their heteronuclear multiple bond correlation data, hydrogen deuterium exchange mass data, and quantum chemical analysis using density functional theory calculations. One degradation product had a structure that could only be explained by unusual rearrangement involving conversions of N-oxide into hydroxylamine, similar to Meisenheimer rearrangement. The physicochemical, as well as absorption, distribution, metabolism, excretion, and toxicity properties of BPT and its characterized photodegradation products were evaluated in silico by ADMET Predictor software.

Preparation method of important intermediate of bepotastine

The invention discloses a preparation method of an important intermediate of bepotastine. The preparation method is used for preparing (S)-(-)-4-[(4-chlorophenyl)(2-pyridyl)methoxy]piperidine. The preparation method comprises that a racemate ((+/-)-4-[(4-chlorophenyl)(2-pyridyl)methoxy]piperidine) and S-binaphthylphosphate undergo a reaction to produce a salt, the salt is dissociated by an alkali, and the dissociated salt is beat to form slurry of (S)-(-)-4-[(4-chlorophenyl)(2-pyridyl)methoxy]piperidine. The (S)-(-)-4-[(4-chlorophenyl)(2-pyridyl)methoxy]piperidine has optical purity of 99.0% or more. The disclosed chiral resolution method is simple, has a good industrial production prospect, and has a great significance for the industrial production of bepotastine.
