Used primarily in research to study inflammatory diseases and neurological disorders due to its ability to inhibit phosphodiesterase 4 (PDE4). This inhibition increases cyclic AMP levels, leading to reduced production of pro-inflammatory cytokines. It has shown potential in preclinical studies for treating conditions like asthma, multiple sclerosis, and depression. Also used as a tool compound to explore memory enhancement and neuroprotection in animal models. Not approved for clinical use in humans.
