Bisdemethoxycurcumin, a curcumin derivative, ameliorates adjuvant-induced arthritis by suppressing inflammatory reactions and macrophage migration.

Rheumatoid arthritis (RA) is a highly prevalent and chronic inflammatory synovial joint disease manifested by hyperplasia and continuous inflammation. Curcumin (Cur) has been studied for alleviating RA. However, poor stability and oral bioavailability restrict its therapeutic value.

Bisdemethoxycurcumin Inhibits VEGF-Induced HUVECs Proliferation, Migration and Invasion through AMPK/mTOR Pathway-Dependent Autophagy Activation and Cell Cycle Arrest.

Vascular endothelial growth factor (VEGF) is a key mediator of angiogenesis, which plays a key role in the proliferation, migration and invasion of endothelial cell. Bisdemethoxycurcumin (BDMC) is a natural demethoxy curcumin derivative. In this study, we explored the mechanisms whereby BDMC is able to influence the proliferative, migratory and invasive activity of human umbilical vein endothelial cells (HUVECs) in response to VEGF treatment.

Development of pH-sensitive dextran-based methotrexate nanodrug for rheumatoid arthritis therapy through inhibition of JAK-STAT pathways.

Rheumatoid arthritis (RA) is a chronic and symmetrical autoimmune disease that primarily characterized with articular synovial hyperplasia, joint swelling, cartilage and bone destruction. The in-depth understanding of the role of immune signaling pathway inhibitors provides inspiration for the construction of new and more effective strategy for RA therapy. In this study, by loading methotrexate (MTX) into an acetalated dextran biopolymer, AcDEX, we developed a pH-sensitive, MTX-loaded and molecularly targeted nanodrug MTX@pH-AcDEX NPs) to decrease the toxicity of MTX and simultaneously enhance its therapeutic effect.
