Direct Blue 1 (0.1-10 μM, 9 days) can bind α-synuclein and inhibit its aggregation, thus blocking the proliferation of α-synuclein between SH-SY5Y cells[4].
Direct Blue 1 (5-20 μM, 48 h) inhibits RANKL-induced osteoclasts and bone resorption in vitro by inhibiting NF-κB signaling and promoting proteasome-mediated MIF degradation[5].
