Used in research for neurodegenerative disorders, particularly Alzheimer’s disease. Shows potential in improving cognitive function by modulating synaptic plasticity and enhancing memory. Acts as a selective inhibitor of phosphodiesterase-4D (PDE4D), which plays a role in regulating cyclic AMP levels in brain cells. This mechanism supports neuronal communication and may slow cognitive decline. Investigated for possible benefits in Fragile X syndrome and other conditions involving cognitive impairment. Currently in experimental stages, not approved for clinical use.
