Biological Activity
IC50: 0.26 nM (EGFR T790M/L858R), 1.33 nM (EGFR L858R), 4.11 nM (EGFR)[1]
EGFR-IN-44 (Compound 6a) (0-10 µM, 72 h) shows anti-proliferative activities against tumor cell lines[1].
EGFR-IN-44 binds to the ATP binding site of EGFR[1].
EGFR-IN-44 (0-10 nM, 48 h) induces H1975 cell apoptosis via the mitochondrial pathway, arrests cell cycle in G0/G1 phase, and suppresses cell migration[1].
EGFR-IN-44 (0-10 nM, 48 and 72h) shows hypotoxicity against normal cells[1].

-
Incubation Time:72 h
-
Result:Showed anti-proliferative activities with IC50 values of 0.0022 ± 0.001, 0.0048 ± 0.001, and 4.499 ± 0.057 µM against H1975, PC9, and H292 cells, respectively.
-
Cell Line:H1975
-
Concentration:1, 5, and 10 nM
-
Incubation Time:48 h
-
Result:Effectively induced cell apoptosis in a dose-dependent manner. Resulted in 33.7%, 52.4%, and 56.2% apoptosis at 1, 5, and 10 µM, respectively, compared to 5.81% apoptosis in the control group.
-
Cell Line:H1975
-
Concentration:5, 10, and 25 nM
-
Incubation Time:48 h and 72 h
-
Result:Dose-dependently upregulated the expression levels of the proapoptotic proteins Bad and Bax and downregulated the expression level of the antiapoptotic protein Bcl-2. Sufficiently reduced the phosphorylation of EGFR and AKT.
