A potent and selective inhibitor of LTA4 hydrolase (LTA4H) with IC50/Ki of 5 nM/23 nM; inhibits calcium ionophore-induced LTB(4) production in human whole blood (IC50=49 nM).

A new potent allosteric effector of sickle cell hemoglobin; increases the affinity of hemoglobin for oxygen and consequently inhibits its polymerization when subjected to hypoxic conditions.

HLM006474 is a pan inhibitor of E2F. This inhibits E2F4 DNA-binding (IC50: 29.8 μM in A375 cells).HLM006474 causes the viability of both SCLC and NSCLC lines (IC50 ranging from 15 to 75 μM). HLM006474 displays little activities against E2F4 DNA-binding in A375 cells at 10 and 20 μM, apparently inhibits E2F4 DNA-binding at 40 μM, and increasingly suppresses the effect at 60 and 80 μM concentrations.
