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.

In Vitro

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].

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.
