生物活性 | Loureirin B, a flavonoid extracted fromDracaena cochinchinensis, is an inhibitor of plasminogen activator inhibitor-1(PAI-1), with an IC50of 26.10 μM; Loureirin B also inhibitsKATP, the phosphorylation ofERKandJNK, and has anti-diabetic activity. | ||||||||||||||||

体外研究 (In Vitro) | Loureirin B enhances the relative mRNA level of Pdx-1 and MafA. Loureirin B (1, 0.1, and 0.01 μM) increases insulin secretion in Ins-1 cells. Loureirin B (0.01 μM) almost causes no toxicity on cells. Loureirin B improves the level of expressions ofMafAandPdx-1and ATP level. Loureirin B inhibits the KATP current but increases the [Ca2+]i level in Ins-1 cells[1]. Loureirin B inhibits the expression of Col1 and FN, as well as the TGF-β1-mediated up regulation of p-JNK. Loureirin B also inhibits the up regulation of p-ERK that is induced by TGF-β1. Moreover, Loureirin B inhibits the contraction of TGF-β1-stimulated fibroblasts through the down regulation of p-ERK and p-JNK. However, Loureirin B does not suppress the up regulation of p-p38 that is induced by TGF-β1[2]. Loureirin B downregulates both mRNA and protein levels of type I collagen, type III collagen and α-smooth muscle actin in a dose dependent manner in HS fibroblasts. Loureirin B also suppresses fibroblast proliferative activity and redistributes cell cycle, but does not affect cell apoptosis[3]. | ||||||||||||||||
体内研究 (In Vivo) | Loureirin B significantly improves the arrangement and deposition of collagen fibres, decreases protein levels of ColI, ColIII and α-SMA and suppresses myofibroblast differentiation and scar proliferative activity, in a rabbit ear scar model. Loureirin B effectively inhibits TGF-β1-induced upregulation of ColI, ColIII and α-SMA levels, myofibroblast differentiation and the activation of Smad2 and Smad3, in NS fibroblasts[3]. | ||||||||||||||||
