Maackiain (DL-Maackiain) is an orally active multi-target inhibitor with anti-tumor activity and neuroprotective effects. Maackiain activates the AMPK, NLRP3 and Nrf2/HO-1 pathways, and inhibits key targets such as NF-κB, mTOR, MAO-B, NFATc1 and PKCδ, thereby precisely regulating processes including apoptosis, autophagy and pyroptosis. Maackiain also effectively inhibits microglial activation, osteoclast formation, and proliferation and invasion of tumor cells, and protects dopaminergic neurons from damage. Maackiain is applicable to the research of various diseases such as Alzheimer's disease, osteoporosis, sepsis and dengue fever。

Maackiain (40 μM; 1-5 days) suppresses the expression of osteoclast-specific proteins c-Fos, Integrin β3, MMP9, CTSK and NFATc1 in RANKL-stimulated mouse bone marrow macrophages; meanwhile, it downregulates the protein level of NFATc1 and inhibits its nuclear translocation^[3].
Maackiain (40 μM; 1 h) blocks IκB-α degradation and p65 phosphorylation, inhibits RANKL-induced activation of the NF-κB pathway in mouse bone marrow-derived macrophages, and thereby attenuates RANKL-induced calcium oscillations in mouse bone marrow-derived macrophages^[3].
Maackiain (50-100 ng/mL; sequential treatment for 1 h after 3 h of LPS pre-treatment and 1 h of incubation with 5 μM nigericin (HY-127019)) enhances 5 μM nigericin-induced caspase-1 activation and mature IL-1β production in LPS-pretreated human monocytic cell line dTHP-1, and exhibits a dose-dependent effect at concentrations of 50 ng/mL and 100 ng/mL^[4].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
