 Use of BLT-1


BLT-1, a thiosemicarbazone copper chelator, is a selectively scavenger receptor B, type 1 (SR-BI) inhibitor. BLT-1 inhibits the transfer of lipids between high-density lipoproteins (HDL) and cells mediated by SR-BI. BLT-1 has pro-inflammatory functions through neutrophil recruitment[1][2][3].

 BLT-1 Biological Activity

Description BLT-1, a thiosemicarbazone copper chelator, is a selectively scavenger receptor B, type 1 (SR-BI) inhibitor. BLT-1 inhibits the transfer of lipids between high-density lipoproteins (HDL) and cells mediated by SR-BI. BLT-1 has pro-inflammatory functions through neutrophil recruitment[1][2][3].
Related Catalog
In Vitro BLT-1 has IC50s of 60 and 110 nM for cellular DiI-HDL and [3H]CE-HDL uptake in ldlA[mSR-BI] cells[1]. BLT-1 (50 μM; 3 hours) does not induce general defects in clathrin-dependent and -independent intracellular membrane trafficking in HeLa, BSC-1 cells[1]. BLT-1 can inhibit SR-BI-dependent selective uptake of [3H]CE from [3H]CE-HDL by mSR-BI-t1-containing liposomes in cells (IC50=0.057 µM) and liposomes (IC50=0.098 µM) [2].
