MedKoo Cat#: 326886 | Name: Befloxatone

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Befloxatone, also known as MD-370503, is a potent, selective and reversible inhibitor of monoamine oxidase A. Befloxatone inhibited selectively and competitively monoamine oxidase (MAO)-A in human and rat brain, heart, liver and duodenum homogenates with Ki values ranging from 1.9 to 3.6 nM for MAO-A and from 270 to 900 nM for MAO-B. In vitro, befloxatone was more potent at inhibiting MAO-A activity than reference compounds (befloxatone > harmaline > brofaromine > BW 137OU87 > RS 8359 > toloxatone > moclobemide).
