Drofenin is an anticonvulsant. It is an anticholinergic that acts both at the level of the nerves and the muscle fibers (neurotropic musculotropic effect). Drofenin also acts as FIASMA (functional inhibitor of acid sphingomyelinase )
1-Aminodecylidenebis-phosphonic acid, with its potent inhibitory effect on acid sphingomyelinase (IC50= 20 nM), shows selectivity by being less effective against neutral sphingomyelinase (IC50= >100 μM). Additionally, it entirely prevents dexamethasone-induced apoptosis in HepG2 cells.
