Bisdemethoxycurcumin

Bisdemethoxycurcumin is an orally effective curcuminoid. Bisdemethoxycurcumin downregulates pro-inflammatory cytokines in macrophages by inhibiting the phosphorylation of PI3K/Akt and p38 MAPK. Bisdemethoxycurcumin relieves autophagy inhibition and promotes lipophagy to clear vascular smooth muscle foam cells by inhibiting the PDK1/Akt/mTOR pathway. Bisdemethoxycurcumin activates the cAMP/Epac/AMPKα axis and the NRF2/HO-1 antioxidant axis, thereby indirectly inhibiting the phosphorylation of NF-κB p65 and pro-inflammatory outputs such as IL-1β/IL-6/TNF-α, so as to alleviate pulmonary oxidative stress, inflammatory infiltration and pulmonary edema. Bisdemethoxycurcumin blocks NLRP3-mediated pyroptosis and protects cartilage extracellular matrix degradation by activating NRF2/HO-1. Bisdemethoxycurcumin also exerts a synergistic effect with potassium iodide against Candida.

Innate Immunity

Cytokines & Chemokines

Bisdemethoxycurcumin (2.5 μM; 25 h) reduces the mRNA expression levels of IL-6, IL-1β, TNF-α and MCP-1 in LPS (HY-D1056)-induced RAW264.7 cells^[1].

Pyroptosis

Bisdemethoxycurcumin (2-8 μM; 48 h) activates the Nrf2/HO-1 pathway in a dose-dependent manner, and inhibits pyroptosis in TBHP-stimulated ATDC5 chondrocytes by upregulating Nrf2 and HO-1, and downregulating NLRP3, GSDMD, Caspase 1 and IL-1β, with a treatment duration of 48 h^[2].

Inflammasome

Bisdemethoxycurcumin (8 μM; 24 h) significantly reduces the TBHP-induced upregulation of ADAMTS5 and NLRP3 protein expressions in ATDC5 chondrocytes^[2].

Lipid Metabolism

Bisdemethoxycurcumin (10-40 μM; 12 h) reduces lipid accumulation in mouse aortic vascular smooth muscle cells stimulated by oxidized low-density lipoprotein (ox-LDL) (HY-NP013) and promotes cholesterol efflux^[3].

Oxidative Stress

Fungal Infection

When Bisdemethoxycurcumin (20-80 μM) is used alone, the amount of hydroxyl radicals it generates shows a strong correlation with the reduction degree of Candida albicans ATCC 10231 biofilms; however, when it is used in combination with potassium iodide, the correlation is only moderate after irradiation^[6].

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.
