In neurodegenerative diseases, using a single molecule that can exert multiple effects to modify the disease may have superior activity over classical "one molecule-one target" approach. Herein, we describe discovery of 6-hydroxybenzothiazol-2-carboxamides as highly potent and selective MAO-B inhibitors. Variation amide substituent led several compounds having diverse side chains with cyclohexylamide 40 displaying highest potency towards (IC50 = 11 nM). To discover new extended efficacy against neurotoxic mechanisms in inhibitors were screened PHF6, R3 tau, cellular tau α-synuclein (α-syn) aggregation. We identified phenethylamide 30 multipotent inhibitor 41 nM) α-syn It showed no cytotoxic on SH-SY5Y neuroblastoma cells, while also providing neuroprotection toxicities induced by tau. The evaluation key physicochemical vitro-ADME properties revealed great potential drug-like small molecules multitarget neuroprotective activity.
