This study explores the potential of 7-amidocoumarins as multitarget agents against Parkinson's and Alzheimer's diseases, by modulating the substitution patterns within the scaffold. Sixteen compounds were synthesized
via 7-amino-4-methylcoumarin acylation, and
in vitro evaluation of the molecules against
hMAO-A,
hMAO-B,
hAChE,
hBuChE and
hBACE1 was performed. Five compounds turned out to be potent and selective
hMAO-B inhibitors in the nanomolar range, six displayed inhibitory activity of
hMAO-A in the low micromolar range, one showed
hAChE inhibitory activity and another one
hBACE1 inhibitory activity. MAO-B reversibility profile of 7-(4’-chlorobenzamido)-4-methylcoumarin ( 10 ) was investigated, with this compound being a reversible inhibitor. Neurotoxicity on motor cortex neurons and neuroprotection against H
2O
2 were also studied, corroborating the safety profile of these molecules. Finally, theoretical ADME properties were also calculated, showing these molecules as good candidates for the optimization of a lead compound. Results suggest that by modulating the substitution pattern at position 7 of the scaffold, selective or multitarget molecules can be achieved.
