8Br-HA is an inhibitor of fragile histidine triad diadenosine triphosphatase (FHIT; IC50= 0.12 μM).1It inhibits the growth of HCC827 and H460 lung cancer cells (GI50s = 0.87 and 5.9 μM, respectively). 1.Kawaguchi, M., Sekimoto, E., Ohta, Y., et al.Synthesis of fluorescent probes targeting tumor-suppressor protein FHIT and Identification of apoptosis-inducing FHIT inhibitorsJ.

PD-L1-IN-1, a powerful PD-L1 inhibitor, demonstrated an IC50 of 115 nM. By forming a robust bond with the PD-L1 protein, PD-L1-IN-1 effectively suppressed tumor growth by enhancing the antitumor immune activity of peripheral blood mononuclear cells in co-cultures with PD-L1 expressing cancer cells (PC9 and HCC827 cells). It significantly elevated the release of interferon γ and induced apoptosis in cancer cells, while exhibiting minimal cytotoxicity in healthy cells [1].
EGFR-IN-1, an orally active and irreversible selective inhibitor targeting L858R T790M mutant EGFR, exhibits strong antiproliferative and antitumor activity, particularly against H1975 cells and first line mutant HCC827 cells. This compound potently inhibits Gefitinib-resistant EGFR L858R T790M mutations with a 100-fold selectivity over the wild-type EGFR.
