LEI110
Based on 1 publication(s) in Google Scholar
LEI110 is a pan-inhibitor of the HRASLS family and an inhibitor of AP-2α, with a Ki of 20 nM against PLA2G16. LEI110 exhibits inhibitory activity against PLA2G16, HRASLS2, RARRES3 and iNAT, with pIC50 values of 7.0, 6.8, 6.8 and 7.6, respectively. LEI110 binds to the active site of PLA2G16, reduces intracellular arachidonic acid levels, and attenuates oleic acid-induced lipolysis. LEI110 stabilizes AP-2α, impairs its DNA-binding ability, inhibits the transcription of DNA damage repair genes, induces the accumulation of oxidative DNA damage, suppresses cell proliferation and clonogenicity, and sensitizes HCC cells to DNA-damaging agents. LEI110 can be used in research related to obesity, fatty liver disease, the common cold and hepatocellular carcinoma.

LEI110 (0.001-100 μM) potently inhibits PLA2G16 (pIC50 = 7.0) and other HRASLS family members (HRASLS2, RARRES3, iNAT) in the cytosolic proteome of overexpressing HEK293T cells, and acts as a selective pan-inhibitor of the HRASLS thiol hydrolase family[1].
LEI110 potently inhibits the enzymatic activity of recombinant human PLA2G16 in vitro, with a Ki of 20 nM[1].
LEI110 (10 μM; 4-8 h) reduces PLA2G16-induced arachidonic acid levels in U2OS cells overexpressing PLA2G16 in a time-dependent manner, with nearly complete inhibition observed after 8 h[1].
LEI110 (10 μM; 24 h pre-incubation followed by co-incubation with 100 μM Oleic Acid (HY-N1446) for 24 h) inhibits oleic acid-induced lipolysis and lipid droplet accumulation in human HepG2 cells[1].
LEI110 (1 h treatment) stabilizes the AP-2α protein in human hepatocellular carcinoma cell line HEP3B, confirming a direct binding interaction between LEI110 and AP-2α[2].
LEI110 (2-128 μM) significantly reduces the viability of human hepatocellular carcinoma cell lines HEP3B, Huh7, MHCC-97H and SNU387 in a dose-dependent manner[2].
LEI110 (administered for 4 consecutive days) inhibits the proliferation of HEP3B human hepatocellular carcinoma cells over a 4-day treatment cycle[2].
LEI110 (20 μM; 10 days) potently inhibits the colony-forming ability of HEP3B human hepatocellular carcinoma cells, reducing the colony formation rate to approximately 25% of that in the control group[2].
LEI110 (0-48 hours) inhibits the expression of DDR genes NUDT1, PARP1, TOP2A and POLD1 in human hepatocellular carcinoma cells in a time-dependent manner, with significant down-regulation detectable as early as 12 hours after treatment[2].
LEI110 (20 μM) induces DNA damage in human hepatocellular carcinoma cell line HEP3B, and the proportion of γH2AX-positive cells doubles compared with that of the control group[2].
LEI110 (3.125-50 μM; 72 hours) exhibits strong synergistic cytotoxicity with the DNA-damaging agents H2O2, hydroxyurea, TH5487 and cisplatin in human hepatocellular carcinoma HEP3B cells, with the highest synergy score (approximately 11) observed in combination with H2O2[2].
