  • Patent number: 11247966
    Abstract: A 4-(p-trifluoromethylbenzyl)-3-fluoro-1,2,4-triphenylamine derivative, a pharmaceutical composition and applications thereof are disclosed. The general chemical formula of the derivative is shown in formula I, where, R is a C1-C6 alkyl group, a cycloalkyl group, a heteroatom-containing cycloalkyl group, an aryl group or a heteroatom-containing aryl group, the heteroatom is selected from N or O, and the n is 0, 1, 2 or 3. The pharmaceutical composition contains any one of the above-mentioned 4-(p-trifluoromethylbenzyl)-3-fluoro-1,2,4-triphenylamine derivatives as an active ingredient, and one or more pharmaceutically acceptable carriers. The derivative and the pharmaceutical composition activate KCNQ channel currents. Thus, the derivative can be applied to prepare a KCNQ potassium channel opener, and can be used as the active ingredients of an antiepileptic pharmaceutical preparation, an antianxiety pharmaceutical preparation and a neuropathic pain-relieving pharmaceutical preparation.
