Ladostigil (Synonyms: TV-3326)

Ladostigil (TV-3326) is a dual inhibitor of cholinesterase and brain-selective monoamine oxidase (MAO), with an IC50 of 37.1 and 31.8 μM for MAO-B and AChE, reapectively. Ladostigil could increase cholinergic transmission, prevent the formation of ROS or their actions and be used for the research of depression and Alzheimer’s disease[1][2].

Ladostigil (1-10 µM) exerts neuroprotective activities, including a prevention of the fall of the mitochondrial membrane potential (ψ), attenuation of apoptotic cascades and an inhibition of ROS production induced by OS insults[2].Ladostigil (1-10 µM) has a significant neuroprotective activity, including inhibition of caspase-3 activation, induction of Bcl-2 and reduction of Bad and Bax gene and protein expression in human neuroblastoma SK-N-SH cells[2].

Ladostigil (17 mg/kg; p.o. daily for 6 weeks) abolishes their hyperanxiety and depressive-like behaviour in the elevated plus maze (EPM) and forced swim tests (FST) tests in adulthood from puberty to prenatally-stressed rats[4].Ladostigil (50 μmol/kg; single p.o.) restores the loss of episodic memory in the object recognition test in rats[3].
