生物活性

Afatinib (BIBW 2992) dimaleate is an orally active, potent and irreversible dual specificity inhibitor of ErbB family (EGFR and HER2), with IC₅₀ values of 0.5 nM, 0.4 nM, 10 nM and 14 nM for EGFR, EGFR, EGFR and HER2, respectively. Afatinib dimaleate can be used for the research of esophageal squamous cell carcinoma (ESCC), non-small cell lung cancer (NSCLC) and gastric cancer.

体外研究(In Vitro)

Afatinib dimaleate (100 nM) sufficiently prevents heregulin-stimulated HER3 phosphorylation.
Afatinib dimaleate (0-10000 nM) effectively inhibits anchorage-independent proliferation of NIH-3T3 cells ectopically expressing EGFR mutants, and inhibits cell proliferation of H1666, H3255, and NCI 1975 cells.
Afatinib dimaleate (48-72 h)shows growth inhibition in HKESC-1, HKESC-2, SLMT-1 and EC-1 cells.
Afatinib dimaleate (0-1 μM, 24-48 h) inhibits AKT and MAPK pathways, and inhibits EGFR and AKT phosphorylation in ESCC cell lines.
Afatinib dimaleate (0-1 μM, 16-48 h) induces G0/G1 cell cycle arrest in HKESC-2 and EC-1.
Afatinib dimaleate (0-1 μM, 24-48 h) effectively induces apoptotic cell death in HKESC-2 and EC-1.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Proliferation Assay

Cell Line:	NIH-3T3 cells, H1666, H3255, and NCI 1975 cells
Concentration:	0, 1, 10, 100, 1000, 10000 nM
Incubation Time:
Result:	Effectively inhibited anchorage-independent proliferation of NIH-3T3 cells ectopically expressing EGFR mutants. Showed inhibition of anchorage independent cell proliferation of various lung cancer cell lines (H1666, H3255, and NCI 1975 cells), with IC₅₀ values of 60 nM, 0.7 nM and 99 nM, respectively.

Cell Viability Assay

Cell Line:	HKESC-1, HKESC-2, SLMT-1 and EC-1 cell lines
Concentration:
Incubation Time:	48 and 72 hours
Result:	Observed over 95% of growth inhibition. The respective IC₅₀ concentrations at 48 hours (HKESC-1=0.078 μM, HKESC-2=0.115 μM, KYSE510=3.182 μM, SLMT-1=4.625 μM and EC-1=1.489 μM) and 72 hours (HKESC-1=0.002 μM, HKESC-2=0.002 μM, KYSE510=1.090 μM, SLMT-1=1.161 μM and EC-1=0.109 μM) were all in lower micro-molar range.

Significantly reduced the phosphorylation level of the downstream effectors of the AKT-mTOR axis especially in HKESC-2 cells.

Afatinib dimaleate (15 mg/kg, Orally, in a schedule of 5 days on plus 2 days off, for two weeks) strongly inhibits the growth of HKESC-2 tumor.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

Administration:	Orally, daily for 25 days
Result:	Resulted in dramatic tumor regression with a cumulative treated/control tumor volume ratio (T/C ratio) of 2% in a standard xenograft model of the epidermoid carcinoma cell line A431, and downregulation of EGFR and AKT phosphorylation. Induced regression of large tumors in this HER2-driven model, effectively controlled xenograft tumor formation by the NCIH1975 cell line, expressing EGFR L858R/T790M, with a T/C value of 12% for doses of 20 mg/kg. Induced more than 50% percent tumor reduction after a 4-week treatment period. Downregulated EGFR, HER2 and HER3 phosphorylation.
