Ladostigil hemitartrate (TV-3326) is a compound that acts as a dual inhibitor of cholinesterase and brain-selective monoamine oxidase (MAO). It has IC50 values of 37.1 μM for MAO-B and 31.8 μM for AChE. In addition, Ladostigil hemitartrate possesses neuroprotective, antioxidant, and anti-inflammatory properties. It is commonly used in research relating to depression and Alzheimer's disease.
Rasagiline-13C3 (mesylate) is intended for use as an internal standard for the quantification of rasagiline by GC- or LC-MS. Rasagiline is an inhibitor of monoamine oxidase B (MAO-B; IC50= 4.43 nM for the rat brain enzyme).1It is selective for MAO-B over MAO-A (IC50= 412 nM for the rat brain enzyme). It inhibits serum and NGF withdrawal-induced apoptosis of PC12 cells when used at concentrations ranging from 0.01 to 100 μM.2Rasagiline inhibits rat brain MAO-Bin vivo (ED50= 0.1 mg/kg).1It reduces cerebral edema in a mouse model of traumatic brain injury.2Rasagiline (0.1 mg/kg)reduces cortical and hippocampal levels of full-length and soluble amyloid precursor protein (APP)in rats and mice. It also reduces α-synuclein-induced substantia nigral neuron loss and improves motor dysfunction in a mouse model of Parkinson's disease.3Formulations containing rasagiline have been used in the treatment of Parkinson's disease.
