Why Monoamine Oxidase B Preferably Metabolizes N-Methylhistamine over Histamine: Evidence from the Multiscale Simulation of the Rate-Limiting Step.
Maršavelski A, Mavri J, Vianello R, Stare J. Maršavelski A, et al. Int J Mol Sci. 2022 Feb 8;23(3):1910. doi: 10.3390/ijms23031910. Int J Mol Sci. 2022. PMID: 35163835 Free PMC article.
This renders the catalytic environment more efficient for N-methylhistamine, giving rise to a lower barrier relative to histamine. In addition, the transition state involving N-methylhistamine appears to be stabilized by the surrounding nonpolar residu …

Urinary N-methylhistamine in asthmatic children receiving azelastine hydrochloride.
Takei S, Shimago A, Iwashita M, Kumamoto T, Kamuro K, Miyata K. Takei S, et al. Ann Allergy Asthma Immunol. 1997 May;78(5):492-6. doi: 10.1016/S1081-1206(10)63237-1. Ann Allergy Asthma Immunol. 1997. PMID: 9164363
Urinary N-methylhistamine excretion showed no diurnal change or influence of meals. CONCLUSIONS: Decreased urinary N-methylhistamine excretion may be a direct reflection of the antihistaminic action of azelastine in vivo. ...
