生物活性

L48H37 is an analog of Curcumin (HY-N0005) with improved chemical stability. L48H37 is a potent and specific myeloid differentiation protein 2 (MD2) inhibitor and inhibits the interaction and signaling transduction of LPS-TLR4/MD2. L48H37 is used for the research of sepsis or lung injury treatment[1].

L48H37 inhibits LPS-induced inflammation, particularly TNF-α and IL-6 production and gene expression in mouse macrophages[1].
L48H37 (0-20 µM; 24 hours) decreases the viability of A549 and H460 cells with IC50 values of 5.3 µM and 2.3 µM, respectively, which is more effective compared to curcumin in lung cancer cells. It shows a low cytotoxicity on normal human lung epithelial cells (BEAS-2B) with IC50 of 21 μM[2].
L48H37 (1, 2, or 4 µM; 16 hours) dose‐dependently inhibited the expression of p‐Cdc2 and Cdc2, and increases the expression of p53. It also shows increased levels of cleaved poly (ADP‐ribosyl) polymerase (PARP) and reduced levels of anti‐apoptotic protein Bcl‐2 in H460 and A549 cells[2].
L48H37 (4 µM; 16 hours) rapidly induces intracellular ROS levels dose-dependently as detected by increased DCF levels in H460 and A549 cells[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
