DL-Maackiain (Maackiain) is extracted from the flowers of maackia amurensis rupr.et maxim. and can induce apoptosis and growth suppression. Maackiain (DL-Maackiain) is a larvicidal agent against Aedes aegypti mosquito.xp Parasitol with a LD50 of 21.95 µg/mL[3]. Extent of induction of apoptosis by maackiain was larger than that by trifolirhizin in human leukemia HL-60 cells[4]. MK (Maackiain) significantly reduced dopaminergic neuron damage in 6-hydroxydopamine (6-OHDA)-exposed worms of the BZ555 strain, with corresponding improvements in food-sensing behavior and life-span. In transgenic worms of strain NL5901 treated with 0.25 mM MK, the accumulation of α-synuclein was diminished by 27% compared with that in untreated worms. Moreover, in worms and the SH-SY5Y cell line, we confirmed that the mechanism of MK-mediated protection against PD pathology may include blocking apoptosis, enhancing the ubiquitin-proteasome system, and augmenting autophagy by increasing PINK1/parkin expression[5]. Maackiain could restrain receptor activator of nuclear factor-κB ligand (RANKL)-stimulated osteoclast formation and hydroxyapatite resorption dose-dependently, and interrupt the structures of F-actin belts in the mature osteoclasts. It also repressed the expressions of osteoclast-specific genes and proteins. Furthermore, Maackiain could inhibit RANKL-stimulated NF-κB and calcium signalling pathways, and dampen Nuclear factor of activated T cell cytoplasmic 1 activity, protein expression and translocation into the nucleus[6].
