Dendrocandin U

Dendrocandin U is a bibenzyl compound found in Dendrobium officinale that exhibits anti-inflammatory activity and α-glucosidase inhibitory effect (IC₅₀ = 9.46 mM). Dendrocandin U inhibits the expression of TLR4 and MyD88 in the TLR4/MyD88/NF-kB pathway, suppresses the phosphorylation of NF-kB p65 and I-kBα, and blocks the nuclear translocation of NF-kB p65. Dendrocandin U inhibits M1 polarization, NO secretion, and TNF-α release in alveolar macrophages, and reduces inflammatory morphological changes in macrophages. Dendrocandin U promotes neurite outgrowth in PC12 cells. Dendrocandin U can be used for research on inflammation-related diseases and type 2 diabetes.

In Vitro

Dendrocandin U (compound 1) (0.01-80 μM; 24 h) shows no cytotoxicity against MH-S cells at concentrations below 20 μM^[1].
Dendrocandin U (0.01-20 μM; 2 h pre-incubation) inhibits NO secretion in LPS/IFN-γ-stimulated MH-S cells^[1].

Dendrocandin U (20 μM; 2 h pre-incubation) attenuates M1-like morphological changes in LPS/IFN-γ-stimulated MH-S cells; inhibits the TLR4/MyD88/NF-κB signaling pathway and nuclear translocation of p-NF-κB p65 in stimulated MH-S cells^[1].
Dendrocandin U (10-20 μM; 2 h pre-incubation) inhibits the expression of M1 markers CD86 and iNOS in stimulated MH-S cells^[1].
Dendrocandin U (compound 11) is a weak α-glucosidase inhibitor with an IC₅₀ of 9.46 mM^[2].
Dendrocandin U (compound 2) (10 μM; 72 h) shows weak neurite outgrowth-promoting activity in PC12 cells, with a differentiation rate of 9.46%^[3].

Cell Viability Assay^[1]

Cell Line:

MH-S alveolar macrophages
Concentration:

0.01, 0.1, 1, 5, 10, 20, 40, 80 μM
Incubation Time:

24 h
Result:

Did not exhibit obvious cytotoxicity at doses below 20 μM.

ELISA Assay^[1]

Cell Line:

MH-S alveolar macrophages
Concentration:

5, 10, 20 μM
Incubation Time:

2 h (pre-incubation); 24 h (stimulated with LPS (1 μg/mL) + IFN-γ (20 ng/mL))
Result:

Inhibited the release of TNF-α at 10 μM.

Immunofluorescence^[1]

Cell Line:

MH-S alveolar macrophages
Concentration:

0, 20 μM
Incubation Time:

2 h (pre-incubation); 6 h (stimulated with LPS (1 μg/mL) + IFN-γ (20 ng/mL))
Result:

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.
