White powder, soluble in organic solvents such as methanol, ethanol, and DMSO, derived from the resin of the Dracaena frondosa tree. | [Uses]
Loureirin B is a component of traditional Chinese medicine which helps combat neurodegenerative diseases. Extracted from the red resin of Dracaena cochinchinensis S.C Chen, known as Dragon’s Blood. | [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]. | [IC 50]
