Clorgiline (INN), or clorgyline (BAN), is a monoamine oxidase inhibitor (MAOI) structurally related to pargyline which is described as an antidepressant.[1][2] Specifically, it is an irreversible and selective inhibitor of monoamine oxidase A (MAO-A).[3] Clorgiline was never marketed,[1] but it has found use in scientific research.[4] It has been found to bind with high affinity to the σ1 receptor (Ki = 3.2 nM)[3][5] and with very high affinity to the I2 imidazoline receptor (Ki = 40 pM).[6]

Clorgiline is also a multidrug efflux pump inhibitor.[7] Holmes et al., 2012 reverse azole fungicide resistance using clorgiline, showing promise for its use in multiple fungicide resistance.[7]
