Biochem/physiol Actions

MONNA (benzbromarone (Benzb) and N-((4-methoxy)-2-naphthyl)-5-nitroanthranilic acid) is a TMEM16A antagonists. It affects the liberation of sarcoplasmic reticulum (SR) calcium in human airway smooth muscle cells.
MONNA is a TMEM16A (ANO1) calcium-activated chloride channel blocker. MONNA blocks rhTMEM16A (ANO1) channel currents in HEK293 cells with and IC50 of 1.27 μM. The compound MONNA does not affect related human or mouse chloride channels bestrophin-1, CLC2 and CFTR at concentrations up to 10 μM.
