生物活性
Stepharine (10, 30 μM) substantially inhibits nitric oxide (NO) release as well as the mRNA and protein expression of pro-inflammatory mediators [inducible nitric oxide synthase, interleukin (IL)-6, tumor necrosis factor (TNF)-α, IL-1β] in LPS-activated BV-2 cells[1].
Stepharine (10, 30 μM) inhibits LPS-induced increase of TLR4 expression, IκBα phosphorylation, and NF-κB p65 nuclear translocation[1].
Stepharine exhibits neuroprotective effects on SH-SY5Y cells cultured with LPS-treated conditioned medium. Stepharine has also shown to inhibit cholinesterase in vitro[1].
