Biological Activity
LDC8201 (14 nM to 30 μM; 72 h) potently inhibits cell viability in EGFRH773_V774insNPH and Her2A775_G776insYVMA Ba/F3 cells (GI50 = 48 nM and 59 nM, respectively), EGFRV769_D770insASV Cuto 14 cells (GI50 = 39 nM), and EGFRH773_V774insNPH Cuto 17 cells (GI50 = 23 nM), with moderate selectivity (6-fold) over EGFR wild-type A431 cells (GI50 = 303 nM)[1].
LDC8201 exhibits moderate in vitro ADME properties, including moderate microsomal and hepatocyte clearance, high plasma protein binding, moderate Caco-2 permeability, low hERG inhibition, and low cytotoxicity in normal cells[1].
LDC8201 (8 decreasing concentrations; 72 h) potently inhibits the growth of Ba/F3-EGFR-H773_V774insNPH cells with a GI50 of 48 nM and an EC50 of 53 nM[2].
LDC8201 (8 decreasing concentrations; 72 h) potently inhibits the growth of Ba/F3-Her2A775_G776insYVMA cells with a GI50 of 59 nM and an EC50 of 86 nM[2].
LDC8201 (8 decreasing concentrations; 72 h) potently inhibits the growth of H1975 cells with a GI50 of 18 nM[2].
LDC8201 (0.01-1 μM) inhibits EGFR activation and downstream ERK signaling in Cuto 17 cells at concentrations as low as 10 nM[2].
LDC8201 (0.01-1 μM) inhibits EGFR activation and downstream ERK signaling in A431 cells at concentrations of 100 nM and above, demonstrating wild-type-sparing activity[2].
LDC8201 (1 μM) has moderate metabolic stability in mouse liver microsomes with an intrinsic clearance of 93 μL/min/mg[2].
LDC8201 (10 μM; 2 h) has moderate permeability across Caco-2 cell monolayers with an apical-to-basolateral Papp of 51 nm/s[2].
